Best VOO Alternatives 2026: ETFs Similar to VOO
VOO is one of the world's best ETFs. But it is not the only option — and depending on your brokerage, account type, and investment goals, a different ETF may serve you better. This guide compares every serious alternative: VTI, IVV, SPLG, SCHB, FXAIX, and global options for non-US investors.

Key Takeaways
- ►SPLG (0.02%) is the cheapest S&P 500 ETF available, costing less than VOO (0.03%) while tracking the identical index
- ►IVV is functionally identical to VOO — same index, same cost, different issuer (BlackRock) — ideal for non-Vanguard brokerage users
- ►VTI holds ~3,700 stocks vs VOO's ~503, adding mid and small-cap exposure at the same 0.03% cost
- ►FXAIX at 0.015% is the cheapest S&P 500 product anywhere but is a Fidelity-only mutual fund, not an ETF
- ►European and UK investors cannot buy US-domiciled ETFs; VUAA and CSPX are the UCITS-compliant S&P 500 equivalents
- ►Holding both VOO and VTI in the same portfolio creates redundancy, not diversification — choose one or the other
- ►For options traders, SPY remains irreplaceable despite its 0.0945% ER — liquidity and daily expirations justify the premium
- ►The right VOO alternative depends on your brokerage, account type, and whether you want S&P 500 or total market exposure
VOO — the Vanguard S&P 500 ETF — has grown to over $550 billion in assets under management and charges just 0.03% annually, making it one of the most cost-efficient investment vehicles ever created. It tracks the S&P 500 index: the 500 largest US publicly listed companies, weighted by market capitalization, representing roughly 80% of total US equity market value.
But VOO is not uniquely optimal for every investor. Depending on your circumstances, a cheaper S&P 500 ETF may exist on your platform. You may want broader US market exposure. You may be a non-US investor barred from purchasing US-domiciled funds. You may prefer total global market coverage over a US-only index. Or you may be at a specific brokerage where a competing product integrates more seamlessly with your tools and automatic investment features.
This guide systematically evaluates every credible alternative to VOO, organized by use case. The goal is not to crown a single winner — VOO is excellent — but to identify the specific conditions under which another ETF serves your goals better.

Historical Performance: VOO vs Alternatives
All five US-domiciled ETFs in the table below track broad US equity indices at near-identical cost. Performance differences reflect index composition (S&P 500 vs total market) and minor tracking differences. Figures represent total returns including dividends reinvested.
| Period | VOO | VTI | IVV | SPLG | SCHB |
|---|---|---|---|---|---|
| 1-Year (2025) | +24.2% | +23.6% | +24.2% | +24.3% | +23.5% |
| 3-Year Ann. (2023–2025) | +11.8% | +11.3% | +11.8% | +11.9% | +11.2% |
| 5-Year Ann. (2021–2025) | +15.1% | +14.8% | +15.1% | +15.2% | +14.7% |
| 10-Year Ann. (2016–2025) | +13.4% | +13.1% | +13.4% | +13.5% | +13.0% |
| Since-inception (approx.) | +14.6% (from 2010) | +14.2% (from 2001) | +10.3% (from 2000) | +11.1% (from 2005) | +13.8% (from 2009) |
Performance figures are approximate annualized total returns. Past performance does not predict future results. Differences between S&P 500 trackers (VOO, IVV, SPLG) reflect minor tracking error only. VTI and SCHB differences reflect index composition (total market vs S&P 500). Educational illustration only.
SPLG: The Cheapest S&P 500 ETF at 0.02%
If minimizing expense ratio on S&P 500 exposure is your primary objective, SPLG (SPDR Portfolio S&P 500 ETF) is the answer. At 0.02%, SPLG charges one-third less than VOO and IVV (both 0.03%) and less than half of SPY (0.0945%). It tracks the exact same S&P 500 index, holds the same approximately 503 securities in the same market-cap weights, and is structured as an open-end fund — not a Unit Investment Trust — enabling continuous dividend reinvestment and securities lending.
State Street launched SPLG in 2005 as a lower-cost companion to SPY, primarily targeting the retail long-term investor segment that the institutional-grade SPY was not optimally designed for. After a repositioning in 2020 that cut its expense ratio from 0.03% to 0.02%, SPLG has grown rapidly — from approximately $5 billion in AUM to over $50 billion as of mid-2026 — as cost-conscious investors migrate toward it.
The primary trade-off versus VOO: SPLG has significantly lower daily trading volume — approximately $300–500 million per day versus VOO's $1–3 billion. For investors making regular monthly contributions or periodic rebalances of typical retail sizes (under $500,000), this liquidity difference is entirely immaterial. The bid-ask spread on SPLG is typically $0.01–0.02, which on a $65 share price represents 0.015–0.030% of the transaction — a one-time cost that pales against the ongoing annual savings.
SPLG's lower share price (approximately $65 versus VOO's $530) also makes it more accessible for investors without fractional share support at their brokerage, since a single share represents a more granular unit of investment. For Roth IRA investors with annual contribution limits, the ability to invest in precise dollar amounts without fractional shares is a genuine practical advantage.
The verdict on SPLG: for pure cost-minimization on S&P 500 exposure without any need for institutional liquidity or options trading, SPLG is objectively superior to VOO at current pricing. The only reason to prefer VOO over SPLG, all else equal, is familiarity with the Vanguard ecosystem and the deeper liquidity of VOO for large transactions.
IVV: The BlackRock Equivalent of VOO
IVV (iShares Core S&P 500 ETF) is the world's largest ETF by assets under management, with over $600 billion in AUM as of mid-2026. It tracks the S&P 500 at a 0.03% expense ratio — identical to VOO — and is structured as an open-end fund with continuous dividend reinvestment and securities lending income that partially offsets the stated expense ratio.
In terms of investment mechanics, IVV and VOO are functionally interchangeable. Both track the same index, charge the same fee, reinvest dividends continuously, lend securities, and have delivered near-identical total returns over their shared history. The historical tracking difference between IVV and VOO against the S&P 500 benchmark is typically within 0.01–0.03% annually — within the range of measurement noise.
The case for IVV over VOO is purely ecosystem-driven. Investors at Fidelity, Merrill Edge, TD Ameritrade, or other non-Vanguard brokerages often find IVV integrates more naturally with their platform's tools, automatic investment features, and tax-lot management systems. iShares products are available on virtually every major US brokerage with zero commission.
IVV's higher daily trading volume versus VOO ($3–6 billion per day versus VOO's $1–3 billion) makes it slightly more liquid for larger transactions and gives it a more robust options market — though neither approaches SPY's liquidity. For institutional investors managing tens of millions in S&P 500 exposure, IVV's larger trading volume and tighter institutional bid-ask spreads make it the preferred open-end fund S&P 500 ETF.
One nuance: BlackRock's securities lending program on IVV has historically generated lending income that effectively reduces the net cost below the stated 0.03% ER. Vanguard's program on VOO does the same. In recent years, both funds' effective tracking difference versus the S&P 500 total return index has been slightly positive — meaning they have essentially matched or marginally exceeded the index after all costs, net of securities lending income. This is the correct way to evaluate real-world fund cost, not the stated expense ratio alone.
VTI: The Total US Market Alternative
VTI (Vanguard Total Stock Market ETF) is the most compelling structural alternative to VOO for long-term investors who want to capture the full breadth of the US equity market rather than just its 500 largest companies. VTI tracks the CRSP US Total Market Index, holding approximately 3,700 stocks across large, mid, small, and micro-cap US companies — at the same 0.03% expense ratio as VOO.
The S&P 500 covers approximately 80% of US market capitalization. The remaining 20% — roughly 2,500–3,500 mid and small-cap companies — are captured by VTI but excluded from VOO. This additional breadth matters theoretically and practically:
Small-Cap Premium (Fama-French)
Academic research (Fama-French 1992, 2015) documents a historical tendency for smaller companies to outperform large-cap over long periods when adjusted for risk. VTI provides marginal exposure to this premium; VOO provides none.
Index-Agnostic Market Coverage
The S&P 500 is a committee-selected index with profitability and liquidity screens. A company can be large but excluded from the S&P 500. VTI's rules-based CRSP methodology captures any investable US company above a minimum size threshold.
Diversification Argument
VTI's 3,700 holdings versus VOO's 503 means individual company risk is further diluted — though mega-caps dominate both funds' returns due to market-cap weighting.
Practical Return Difference
In practice, VTI and VOO move nearly in lockstep because the S&P 500 accounts for 80% of VTI's weight. Annual return differences are typically 0.1–0.5%, often in VOO's favor during large-cap dominated bull markets.
The evidence-based investor community — including institutions like Vanguard itself and academics like William Bernstein and Burton Malkiel — generally favors total market exposure over S&P 500-only for long-term portfolios. The argument is simple: if you believe in passive, cost-minimized investing, you should own the whole market, not a filtered subset. The S&P 500 is a filtered subset; VTI is as close to the whole market as a single US equity fund can provide.
The strongest counter-argument for VOO over VTI is empirical: over the 2010–2025 period, the S&P 500 outperformed the total market index by approximately 0.3–0.5% annualized, driven by the concentration of mega-cap technology companies (Apple, Microsoft, NVIDIA, Amazon, Alphabet, Meta) in the S&P 500. VOO's top 10 holdings constitute approximately 35% of its weight — meaning VOO is effectively a large-cap technology fund with diversified income-generating satellite positions. Whether this concentration continues to be an advantage or becomes a source of mean-reversion risk is the central question for VOO-vs-VTI over the coming decade.
SCHB: The Schwab Total Market Alternative
SCHB (Schwab US Broad Market ETF) is Charles Schwab's answer to VTI — a total US market ETF charging 0.03% that covers approximately 2,500 of the largest US companies across all market-cap tiers. It tracks the Dow Jones US Broad Stock Market Index rather than the CRSP index used by VTI, but the practical difference in composition and returns is negligible.
For investors whose primary brokerage is Charles Schwab, SCHB is the natural core US equity holding. Schwab's platform provides full integration with SCHB for automatic investments, dividend reinvestment plans (DRIPs), and Schwab's portfolio analysis tools. Schwab also offers fractional share trading on SCHB through its Stock Slices program, enabling precise dollar-based investing without size constraints.
Compared directly to VTI: both track the broad US market at 0.03%, both hold thousands of US stocks, and both have delivered within 0.1% of each other annually over the past decade. The choice between them is almost entirely a function of brokerage preference. Schwab investors should use SCHB; Vanguard investors should use VTI.
One distinguishing factor: Schwab also offers SCHA (Schwab US Small-Cap ETF at 0.04%) for investors who want to tilt their portfolio toward small-cap exposure beyond what the broad market provides. Combining SCHB with a small allocation to SCHA gives an explicit small-cap factor tilt — relevant for investors who believe in the Fama-French size premium and want to overweight it relative to market-cap allocation.
FXAIX: The Cheapest Product Period — But Not an ETF
FXAIX (Fidelity 500 Index Fund) is the cheapest S&P 500 investment product available anywhere at 0.015% — half the cost of VOO. On a $100,000 investment, FXAIX costs $15 per year versus VOO's $30. Over 30 years at 8% gross returns, this $15 annual difference compounds to approximately $1,800 of additional wealth — real money, though modest relative to overall portfolio value at that horizon.
However, FXAIX is a mutual fund, not an ETF. This distinction matters in several practical ways:
- →Fidelity-only availability: FXAIX can only be purchased through Fidelity. You cannot buy it at Schwab, Vanguard, Merrill, or any other brokerage. If you ever transfer your account, you must sell FXAIX (potentially a taxable event) before moving.
- →End-of-day NAV execution: Mutual fund trades execute at the closing NAV, calculated after market close. You cannot set a limit order or control your exact execution price. For buy-and-hold investors, this is irrelevant; for tactically timed entries, it is a constraint.
- →No intraday liquidity: You cannot sell FXAIX during market hours and receive same-day proceeds at a price of your choosing. Settlement is at end of day. Again, irrelevant for long-term investors; meaningful for anyone who needs intraday access.
- →No options market: Mutual funds cannot be used as options underlyings. If you ever want to write covered calls or hedge your S&P 500 position with puts, FXAIX provides no path to that strategy.
- →No minimum investment at Fidelity: Fidelity eliminated the minimum investment on FXAIX, making it accessible for any dollar amount — a genuine advantage for small investors starting out.
For committed Fidelity users — particularly in tax-advantaged accounts where portability and intraday liquidity are irrelevant — FXAIX is the optimal S&P 500 product on pure cost grounds. In a Fidelity Roth IRA held for 30 years, the compounding advantage of 0.015% vs 0.03% is a legitimate reason to choose FXAIX. Beyond that specific use case, VOO's ETF structure, portability, and broader availability make it the more flexible choice.
VOO Alternatives for Non-US Investors: UCITS ETFs
Investors resident in the European Union, the United Kingdom, and many other non-US jurisdictions face a regulatory barrier that American investors rarely consider: MiFID II and the EU's PRIIPS regulation prohibit the retail distribution of ETFs that do not produce a Key Information Document (KID) in the required format. US-domiciled ETFs — including VOO, IVV, VTI, SPLG, and SPY — do not comply with PRIIPS/MiFID II, and European brokers are therefore prohibited from selling them to retail clients.
For non-US investors, the equivalent products are UCITS ETFs— funds domiciled in Ireland or Luxembourg that comply with EU's UCITS framework and produce the required KID documentation. The primary UCITS alternatives to VOO are:
Vanguard's own UCITS S&P 500 ETF, domiciled in Ireland. The accumulating share class automatically reinvests dividends (no withholding tax drag for most EU investors), making it tax-efficient for European investors in accumulation phase. This is the closest European equivalent to VOO. Available on most European brokers.
BlackRock's UCITS S&P 500 ETF — the most liquid S&P 500 ETF on European exchanges with over $80 billion in AUM. Available in both accumulating (CSPX) and distributing (CSPU) share classes. Excellent liquidity on the London Stock Exchange and Euronext Amsterdam.
Tracks the MSCI World Index — approximately 1,500 large and mid-cap companies across 23 developed markets including the US (~70%), Europe, Japan, and other developed economies. Provides built-in international diversification that European investors relying solely on S&P 500 ETFs lack.
Covers both developed and emerging markets — approximately 3,900 holdings across 40+ countries. VWCE (accumulating) is one of the most popular 'one-fund portfolio' solutions for European passive investors, providing complete global market coverage in a single ETF.
European UCITS equivalents cost more than their US counterparts — typically 0.07% versus 0.02–0.03% for the best US ETFs — reflecting the smaller scale of the European ETF market and the compliance costs of UCITS registration. The fund management industry in Europe is less consolidated, creating less fee competition than in the US where Vanguard, BlackRock, and State Street have driven fees toward the floor over two decades.
One significant advantage of Irish-domiciled UCITS ETFs for non-US investors: Ireland has a tax treaty with the United States that reduces the US dividend withholding tax on S&P 500 dividends from 30% (for funds domiciled outside the treaty network) to 15%. This treaty benefit is passed through to UCITS ETF shareholders in the form of higher net dividends, partially offsetting the higher expense ratio compared to US-domiciled equivalents.

Decision Matrix: Which VOO Alternative Is Right for You?
The right ETF is not a universal answer — it depends on your specific situation. Use this decision matrix to identify the optimal choice for your brokerage, account type, and investment goals.
The S&P 500 Index: What VOO and Its Alternatives Actually Own
Understanding what the S&P 500 actually is — and is not — is essential context for evaluating ETFs similar to VOO. The S&P 500 is not simply the 500 largest US publicly listed companies. It is a committee-selected indexmaintained by S&P Global, applying a set of eligibility criteria including: US domicile, minimum market capitalization (currently approximately $20.5 billion), minimum public float of 50%, inclusion in major US exchanges, and a profitability screen requiring positive reported earnings over the most recent four quarters.
This committee-based selection creates a meaningful but often overlooked distinction from total market indices. A company can be extremely large and yet be excluded from the S&P 500 — as happened with Tesla for several years and as happens regularly with recently IPO'd companies that have not yet met the profitability screen. When these companies are eventually added to the S&P 500, index funds must buy them, creating what academic research calls "index reconstitution costs" — real return drag from the predictable buying pressure that occurs at reconstitution.
As of mid-2026, the S&P 500's top 10 holdings — Apple (AAPL), Microsoft (MSFT), NVIDIA (NVDA), Amazon (AMZN), Alphabet (GOOGL/GOOG), Meta (META), Berkshire Hathaway (BRK.B), Broadcom (AVGO), Tesla (TSLA), and JPMorgan Chase (JPM) — represent approximately 35–38% of the index's total weight. VOO, IVV, SPLG, and SPY — all tracking this same index — therefore have highly concentrated mega-cap technology exposure within a nominally diversified wrapper.
This concentration is both VOO's greatest strength and its primary risk. The strength: these ten companies have driven the majority of S&P 500 gains over the past decade, and their enormous market caps reflect genuine economic dominance — deep moats, strong free cash flow, and global platform businesses. The risk: any structural shift in technology sector valuations, regulatory environments (antitrust, AI regulation), or macroeconomic conditions disproportionately affects S&P 500 ETFs relative to more diversified alternatives.
This is exactly why VTI, SCHB, and ITOT have a theoretical diversification advantage — their inclusion of mid and small-cap companies slightly dilutes mega-cap concentration, reducing single-sector dominance from roughly 35% (S&P 500) to closer to 28–30% (total market). Whether this additional breadth produces better risk-adjusted returns over the investor's specific time horizon remains an open empirical question.
Expense Ratio Compounding: The Long-Term Dollar Impact
The compounding arithmetic of expense ratios is frequently cited but rarely shown in full detail. The following table presents the actual terminal wealth difference between the cheapest (SPLG at 0.02%) and most expensive (SPY at 0.0945%) S&P 500 ETF available, across multiple investment sizes and time horizons, assuming 8% gross annual return. All figures are nominal (not inflation-adjusted).
| Initial Investment | Years | SPLG (0.02%) | VOO (0.03%) | IVV (0.03%) | SPY (0.0945%) | SPLG vs SPY Advantage |
|---|---|---|---|---|---|---|
| $10,000 | 10 | $21,580 | $21,577 | $21,577 | $21,543 | +$37 |
| $10,000 | 20 | $46,571 | $46,563 | $46,563 | $46,396 | +$175 |
| $10,000 | 30 | $100,555 | $100,520 | $100,520 | $100,063 | +$492 |
| $100,000 | 10 | $215,800 | $215,765 | $215,765 | $215,431 | +$369 |
| $100,000 | 20 | $465,710 | $465,626 | $465,626 | $463,957 | +$1,753 |
| $100,000 | 30 | $1,005,552 | $1,005,196 | $1,005,196 | $1,000,629 | +$4,923 |
| $500,000 | 20 | $2,328,548 | $2,328,129 | $2,328,129 | $2,319,783 | +$8,765 |
| $500,000 | 30 | $5,027,760 | $5,025,982 | $5,025,982 | $5,003,145 | +$24,615 |
Assumes 8% gross annual return. Net returns: SPLG at 7.98%, VOO at 7.97%, IVV at 7.97%, SPY at 7.9055%. For illustrative purposes only. Does not account for taxes, bid-ask spreads, tracking differences, or securities lending income. Source: mathematical projection only — not historical return data.
The table demonstrates several important points. First, the difference between SPLG, VOO, and IVV is minimal — we are talking about hundreds of dollars over 30 years on a $100,000 investment, not thousands. The marginal cost advantage of SPLG over VOO is real but not life-changing. Second, the difference between low-cost alternatives (VOO/SPLG/IVV) and SPY is more substantial — nearly $5,000 over 30 years on $100,000, or $25,000 on $500,000. This is the most actionable finding: if you are holding SPY in a long-term buy-and-hold context and not using it for options, switching to a lower-cost alternative is clearly mathematically advantageous.
Third, the numbers confirm that the primary determinant of long-term wealth is not the choice between VOO and its near-identical peers — it is asset allocation, savings rate, time in the market, and behavioral discipline. An investor who picks VOO over SPLG and saves $1,000 more per year will end up with vastly more wealth than one who optimizes for the last basis point of expense ratio but contributes less or invests more conservatively. Expense ratio optimization matters most at the margin — after the bigger decisions are already right.
Factor ETFs: VOO Alternatives with a Tilt
For investors who want to move beyond pure passive market-cap weighting, factor ETFs provide systematic exposure to return premiums identified by academic finance research. These are not simple alternatives to VOO — they involve higher expected volatility, potential tracking error versus the broad market, and the behavioral challenge of underperforming during extended periods when the targeted factor is out of favor.
The most well-documented equity risk factors, beyond market beta itself, are:
- →Value (VTV, IVE, AVUV): Companies trading at low price-to-book, price-to-earnings, or price-to-cash-flow ratios relative to the market. Vanguard Value ETF (VTV, 0.04%) captures the large-cap value premium. Avantis US Small Cap Value ETF (AVUV, 0.25%) targets the small-cap value premium where the factor has historically been strongest.
- →Small-Cap (IJR, VBR): Smaller companies have historically earned a risk premium over large-cap. iShares Core S&P Small-Cap ETF (IJR, 0.06%) and Vanguard Small-Cap Value ETF (VBR, 0.07%) provide targeted small-cap exposure. Note the small-cap premium has been absent or negative in some recent periods.
- →Momentum (MTUM, QMOM): Stocks with strong recent price performance tend to continue outperforming over the next 3–12 months. iShares MSCI USA Momentum Factor ETF (MTUM, 0.15%) captures US large-cap momentum. The momentum factor has strong empirical support but high turnover and associated costs.
- →Quality (QUAL, DGRO): Companies with high profitability, stable earnings, and low debt. iShares MSCI USA Quality Factor ETF (QUAL, 0.15%) and Vanguard Dividend Growth ETF (DGRO, 0.08%) provide quality-tilted alternatives to market-cap VOO.
- →Low Volatility (USMV, SPLV): Stocks with lower historical volatility that have empirically delivered comparable returns to the market with less drawdown. iShares MSCI USA Min Vol Factor ETF (USMV, 0.15%) is the largest low-volatility ETF.
For a deeper exploration of factor investing and how to build a factor-tilted ETF portfolio, see the factor ETFs guide. The critical caveat: factor premiums are not guaranteed, may take decades to manifest, and require behavioral discipline to hold through extended underperformance. For most investors, a simple VOO or VTI position captures the market premium — the most reliable and largest documented equity risk premium — without the complexity and behavioral risk of factor tilts.
Tax Considerations: VOO vs Alternatives in Taxable Accounts
For investors holding ETFs in taxable brokerage accounts — as opposed to IRAs, 401(k)s, or other tax-advantaged vehicles — the tax treatment of capital gains distributions and dividends becomes a meaningful selection criterion. All of the major ETFs discussed in this guide (VOO, VTI, IVV, SPLG, SCHB) are highly tax-efficient by design, primarily because the ETF creation/redemption mechanism allows funds to flush unrealized capital gains from the portfolio without triggering taxable distributions to shareholders.
Vanguard holds a structural tax advantagethrough its patented share class structure. Vanguard's ETFs are a share class of their equivalent mutual funds — for example, VOO and VFIAX (Vanguard 500 Index Fund Admiral Shares) are different share classes of the same fund. This structure allows Vanguard to use its ETF share class to distribute low-cost-basis shares to authorized participants, reducing unrealized gains in the mutual fund share class. This patent expired in 2023, allowing other fund companies to potentially replicate the structure — but Vanguard currently has the longest track record of tax-efficient distributions.
In practice, all major S&P 500 ETFs have generated minimal capital gains distributions in recent years. The tracking difference — which measures actual return versus index — is the most important tax-adjusted metric, and all major low-cost index ETFs deliver tracking differences within 0.05% of their stated expense ratios, confirming efficient after-tax performance. For detailed ETF tax guidance including how capital gains distributions, dividend tax treatment, and wash-sale rules apply to ETF investing, see theETF taxes guide.
One tax-specific use case favors holding multiple VOO alternatives: tax-loss harvesting. When VOO declines significantly — as during the 2022 bear market when the S&P 500 fell approximately 19.4% — investors in taxable accounts can sell VOO to realize a capital loss (reducing tax liability) and immediately reinvest in IVV or SPLG, maintaining substantially identical market exposure while the 30-day wash-sale clock resets. This strategy requires holding at least two substantially similar but not identical ETFs to execute cleanly. Understanding the full mechanics of tax-loss harvesting pairs is covered in theETF portfolio construction guide.
Dollar-Cost Averaging into VOO Alternatives
Regardless of which VOO alternative you select, the mechanism through which you build your position matters as much as the fund choice. Dollar-cost averaging (DCA) — investing a fixed dollar amount at regular intervals regardless of market price — is both the most practical and most psychologically sustainable approach for long-term wealth building through passive index funds.
DCA works particularly well with low-cost, broad market ETFs like VOO, VTI, SPLG, and their alternatives because: the funds are highly diversified (no single company represents more than ~7% of assets), liquidity is ample for any retail purchase size, bid-ask spreads are negligible relative to the investment amount, and the underlying indices have never failed to recover new highs over sufficiently long time horizons in US market history.
For a systematic approach to deploying capital into these ETFs over time — including the mechanics of automatic investments, optimal contribution frequency, and how to handle lump-sum contributions versus DCA — see thedollar-cost averaging guide.
One practical note on DCA with specific VOO alternatives: SPLG's lower share price (~$65) versus VOO (~$530) makes it mathematically easier to invest precise dollar amounts without fractional share support. An investor automating $500 monthly contributions can buy approximately 7 full shares of SPLG versus 0 full shares of VOO without fractional support. At most major brokerages (Fidelity, Schwab, Robinhood), fractional shares are available for both, eliminating this distinction — but it remains relevant at older brokerages or in employer-directed 401(k) plans that may not support fractional ETF shares.
Building a Complete Portfolio Around a VOO Core
VOO and its alternatives are typically held as the core equity positionin a broader portfolio, not as standalone investments. The classic two-fund portfolio pairs a US stock fund (VOO, VTI, or an equivalent) with a bond fund; the classic three-fund portfolio adds international equity. These frameworks — popularized by Vanguard founder John Bogle and the Bogleheads community — remain the most evidence-based portfolio construction approaches for long-term individual investors.
A sample low-cost three-fund portfolio for a 35-year-old US investor in accumulation phase:
| Position | Allocation | Vanguard Option | Schwab Option | iShares Option |
|---|---|---|---|---|
| US Equity Core | 60% | VTI (0.03%) | SCHB (0.03%) | ITOT (0.03%) |
| International Equity | 25% | VXUS (0.07%) | SCHF+SCHE | IXUS (0.09%) |
| US Aggregate Bonds | 15% | BND (0.03%) | SCHZ (0.03%) | AGG (0.03%) |
Substituting VOO for VTI in the US equity sleeve is perfectly valid — the difference is minor and the choice should be driven by brokerage convenience and personal preference for S&P 500 vs total market. For investors who prefer the S&P 500's larger-cap focus, VOO or SPLG is the right choice. For investors who prefer maximum breadth at the same cost, VTI or SCHB. For comprehensive guidance on portfolio construction, asset allocation, and rebalancing, see thecomplete ETF portfolio building guide.
The bond component deserves mention: as investors approach retirement, the bond allocation typically increases to provide income stability and reduce portfolio volatility.

Common Mistakes When Choosing VOO Alternatives
The universe of ETFs similar to VOO is well-defined and the differences between top options are small. Nevertheless, investors make recurring mistakes in this decision:
- →Chasing past performance within near-identical funds: If VOO returned 24.2% and VTI returned 23.6% in a given year, it does not mean VOO will outperform next year. The difference reflects index composition — the S&P 500 happened to outperform mid/small-cap in that period. Both are excellent; neither is predictively better than the other based on one-year differences within the range of tracking noise.
- →Holding SPY for long-term buy-and-hold by default: Many investors hold SPY simply because it is the most famous S&P 500 ETF. For pure buy-and-hold without options or tactical trading, SPY's 0.0945% ER is 3-4x more expensive than VOO, IVV, or SPLG tracking the same index. There is no defensible reason to hold SPY for long-term passive investing unless switching would trigger a large taxable event.
- →Treating VOO and VTI as different asset classes: Some investors hold both VOO and VTI thinking they are diversifying across different asset classes. They are not — both are US equity funds with over 80% overlap. The marginal diversification from adding a total market fund on top of an S&P 500 fund is negligible. Choose one or the other.
- →Ignoring brokerage-specific advantages: At Fidelity, FXAIX costs 0.015% versus 0.03% for VOO. At Schwab, SCHB integrates natively with all Schwab portfolio tools. At Vanguard, VOO trades commission-free with fractional shares and no transaction fees. Ignoring platform-specific advantages leaves real money and convenience on the table.
- →Switching funds in taxable accounts without tax analysis: If you hold $300,000 of SPY with $100,000 of unrealized gains in a taxable account, selling to buy VOO triggers a $20,000+ federal tax bill (assuming 20% long-term capital gains rate) to save $64.50 per year. That is a 300+ year payback period. Calculate the tax breakeven before switching funds in taxable accounts.
