Best Index Funds and ETFs to Buy in 2026: Ranked by Expense Ratio, Returns, and Risk Profile

The difference between the cheapest and most expensive index fund tracking essentially the same stocks will cost you roughly $9,500 per $100,000 invested over 30 years. FNILX charges literally nothing in annual fees. SPY charges 0.095% for a nearly identical basket of large-cap U.S. stocks. Both give you the S&P 500. One quietly takes more of your money while doing it.

I’ve spent years helping people sort through this exact decision, and the frustrating part is that most “best index funds” articles hand you a list of 10 or 15 tickers and say “pick one.” That’s like a doctor listing every medication for your condition without asking about your health history. This guide tries to do two things those lists skip: match fund types to actual investor situations before recommending anything, and flag which funds to skip depending on your circumstances, not just which ones look good in a comparison table.

Ten funds. Five categories. Real expense ratios, 5-year returns, and a blunt word on who each fund is actually for.

The Decision Matrix: Find Your Fund in 60 Seconds

Before touching a single ticker, figure out which column you fall into. Most guides skip this entirely, which is most of the problem.

One Fund for the Rest of Your Life

If you had to own exactly one fund forever, a U.S. total stock market fund is probably it. Large caps, mid caps, small caps, every sector, one ticker. That’s the pitch.

#1: Vanguard Total Stock Market ETF (VTI)

Expense ratio: 0.03% (effectively closer to 0.02% after securities lending revenue). Five-year annualized return: roughly 13.7%. Minimum investment: $1, or $1 with fractional shares at most brokers. Holdings: about 3,517 stocks. And it has never distributed a capital gain in its entire history, going back to inception in 2001.

Many investors treat VTI as the benchmark everything else gets measured against. What most people miss is the securities lending program: Vanguard generated $194 million from it in fiscal year 2025, which effectively drops the net expense ratio to about 0.02%, according to data from Optimized Portfolio. Marginally cheaper than the already cheap stated cost.

The 25 years of zero capital gain distributions trace back to Vanguard’s dual share-class structure, where the ETF and the mutual fund equivalent (VTSAX) share the same underlying portfolio and flush low-basis shares through the ETF creation/redemption process. That patent expired in 2023. Vanguard still maintains the structure, but competitors are catching up.

One thing to know before buying: VTI is 100% U.S. stocks. International exposure requires a separate fund, like VXUS. VTI does not do that work for you.

If you need a brokerage account to get started, we’ve ranked the best stock brokerage accounts for beginners and active traders with a focus on which platforms offer fractional shares and zero commissions on ETFs.

S&P 500 Funds: Four Tickers, One Index, Wildly Different Fees

Four funds track essentially the same 500 stocks. The fees are not the same, and over 30 years that gap is not trivial.

#2: Fidelity ZERO Large Cap Index (FNILX)

Expense ratio: 0.00%. Five-year annualized return: 13.2%. Minimum investment: $0.

FNILX is the loss leader of the index fund world. Fidelity waives all fees because they want you on their platform buying other products. The catch: it tracks the “Fidelity U.S. Large Cap Index,” not the S&P 500 itself, which lets Fidelity skip the S&P licensing fee. In practice the holdings are nearly identical, and the 0.5% return gap versus VOO over five years likely reflects minor index-tracking differences and timing, not some structural flaw in the fund.

Worth skipping if you want an ETF (FNILX is mutual fund only), if you trade at a brokerage other than Fidelity (it’s exclusive to their platform), or if you’re worried about being locked into one ecosystem. That last point is worth taking seriously. If you ever want to move your account, FNILX doesn’t travel well. You’d sell, potentially triggering a taxable event, and start over.

#3: Schwab S&P 500 Index Fund (SWPPX)

Expense ratio: 0.02%. Five-year annualized return: 13.7%. Minimum investment: $1.

SWPPX doesn’t get enough credit, and honestly this is the one I’d probably steer most beginners toward if they aren’t already committed to Fidelity. It’s a genuine S&P 500 tracker (not a proprietary clone), it comes in mutual fund format which makes automatic investments easier to set up, and the 0.02% expense ratio actually undercuts Vanguard’s VOO by a basis point. Schwab customers especially: there’s almost no reason not to use this as a core holding.

#4: Vanguard S&P 500 ETF (VOO) and iShares Core S&P 500 ETF (IVV)

Expense ratio: 0.03% each. Five-year annualized return: 13.7% each. VOO sits at $860 billion in AUM; IVV is in the same neighborhood.

These two are functionally interchangeable for a long-term investor. Same index, same fee, same returns. VOO benefits from Vanguard’s dual share-class structure; IVV uses the standard ETF creation/redemption mechanism, which is also highly tax-efficient. Pick whichever your brokerage makes easiest to buy and stop thinking about it.

#5: SPDR S&P 500 ETF Trust (SPY)

Expense ratio: 0.095%. Five-year annualized return: 13.6%.

SPY launched in 1993 and still carries a kind of name-brand premium that its fees don’t justify for most people reading this. At 0.095%, you’re paying more than three times what VOO charges for the same stocks. The reason it still has hundreds of billions in assets despite this: liquidity. SPY has the tightest bid-ask spreads and the deepest options market of any ETF on Earth. Active traders and institutions genuinely need that. Long-term buy-and-hold investors probably don’t, though I’ll acknowledge there are edge cases, people who use covered calls, for instance, where SPY’s options liquidity matters. For a pure buy-and-hold strategy, you’re paying 0.065% per year for a feature you’ll likely never use. On $100,000, that’s $65 annually, compounding against you for decades.

International Stocks: The Half That Most Portfolios Are Missing

#6: Vanguard Total International Stock ETF (VXUS)

Expense ratio: 0.05%. Holdings: roughly 5,000 non-U.S. stocks across developed and emerging markets. Dividend yield: 2.67%. AUM: $149.99 billion.

(On the five-year return: international has lagged U.S. meaningfully over the past decade, so any comparison number here deserves skepticism. Past five years are not the reason to buy this fund.)

The case for VXUS isn’t about chasing returns. Anyone who bought it as a growth play over the last ten years has been frustrated. The actual argument is something closer to insurance. U.S. stocks are at historically elevated valuations relative to international markets in 2026, and Fama-French research suggests international diversification dampens sequence-of-returns risk, which matters most for anyone within 10 years of retirement. Whether that plays out this decade, I genuinely don’t know. It might not. But the 2.67% dividend yield is also notably higher than what VTI pays, reflecting the fact that many international companies return capital as dividends rather than buybacks.

One thing that almost never comes up in other guides: be careful about where you hold VXUS. In a taxable account, you can claim the foreign tax credit on dividends and recover some of those foreign taxes on your U.S. return. In a traditional IRA or 401k, that credit disappears entirely. The White Coat Investor’s breakdown of ETF tax efficiency estimates this can cost you 0.3 to 0.5% per year in lost credits. Real money, worth knowing before you decide which account to park this in.

Bonds: Where Most Guides Get Lazy

#7: Vanguard Total Bond Market ETF (BND)

Expense ratio: 0.03%. Yield: roughly 4.0%. Holdings: about 10,000 U.S. investment-grade bonds. Duration: about 6 years.

BND is the default bond recommendation everywhere, and it’s fine for the right investor. But here’s what needs to be said plainly: that 6-year duration means if interest rates rise another 1%, the fund’s price drops roughly 6%. You could collect 4% in yield and lose 6% in principal in the same year. That math doesn’t work for money you need in the near term.

If you’re a near-retiree who wants safe yield with minimal price volatility, a high-yield savings account paying 4.21% (Axos, no conditions) or up to 5.00% (Varo, with conditions) carries zero duration risk and full FDIC insurance. We’ve ranked these in our guide to the best high-yield savings accounts of 2026. For investors who want bond exposure with minimal rate sensitivity, SGOV (iShares 0-3 Month Treasury Bond ETF, 0.09% expense ratio, roughly 3.59% yield) parks your money in T-bills that barely budge when the Fed moves.

BND makes sense for investors with a 5+ year time horizon who want bonds as a portfolio stabilizer, not a cash substitute. Those are different jobs. Know which one you’re hiring for before you buy.

Dividend ETFs: The Income Debate

#8: Schwab U.S. Dividend Equity ETF (SCHD)

Expense ratio: 0.06%. Dividend yield: roughly 3.5%. Holdings: about 100 U.S. dividend-paying stocks. Morningstar rating: Gold.

SCHD has become something of a cult favorite in personal finance communities, and the Morningstar Gold rating isn’t undeserved. The fund screens for companies with at least 10 years of consecutive dividend payments and strong financial health metrics, which filters out a lot of the garbage that ends up in other dividend funds.

The 2026 portfolio skews defensive: consumer staples like Coca-Cola, PepsiCo, and Procter & Gamble make up about 19% of the fund, and energy names like Chevron, ConocoPhillips, and EOG Resources account for 16%, per StockAnalysis data. That helped in 2022, when SCHD dropped roughly 16% versus 19% for the S&P 500. It’s also exactly why SCHD has lagged in every tech-driven bull market since. The income doesn’t fully compensate for that gap in most years, and anyone who’s compared five-year total returns side by side with VTI has seen the difference.

#9: Vanguard Dividend Appreciation ETF (VIG)

Expense ratio: 0.05%. Dividend yield: roughly 1.7%. Holdings: about 300 stocks. Morningstar rating: Gold.

VIG takes the opposite approach. Rather than hunting for high current yield, it holds companies that have increased their dividends for at least 10 consecutive years, which tends to pull in more growth-oriented businesses. The yield is lower, but total return has historically been higher as a result. If I had to pick one of the two for a taxable account, I’d lean VIG, though I hold neither personally and I’ve seen smart people land on both sides of this one.

Both dividend funds share the same tax problem for people accumulating in taxable accounts: dividends are taxable when received, even if you reinvest them automatically. A total market fund like VTI generates most of its return through price appreciation, which you don’t owe taxes on until you sell. In a Roth IRA, this whole concern goes away.

Sector Funds: QQQ vs. VGT

These two get conflated constantly. QQQ tracks the 100 largest non-financial Nasdaq stocks, which means it includes Amazon, Costco, and PepsiCo alongside the tech giants. VGT is pure technology sector. Three stocks (NVIDIA, Apple, Microsoft) make up 44.6% of the entire fund, per StockAnalysis. When tech runs, VGT runs harder. When tech corrects, it falls further. Neither of those things is going to stop being true.

If you already own VTI, think carefully before adding QQQ. The overlap is massive. QQQ’s top holdings are all in VTI, just at lower weights. Buying both means double-dipping on the same companies without realizing it. If you want tech exposure beyond what VTI already provides, VGT gives you a purer and cheaper version of that bet.

VGT is also not for investors who flinch at 30%+ drawdowns. Three stocks controlling nearly half the fund isn’t diversification. It’s a concentrated wager on the continued dominance of NVIDIA, Apple, and Microsoft. That bet has paid off for years. Whether it continues is genuinely unknowable.

If you’re drawn to sector bets and individual stock picks alongside these index funds, our analysis of what stocks to buy in January 2026 covers some of the same growth themes from a single-stock perspective.

Building an Actual Portfolio

Start with a core before adding anything else. A beginner accumulator needs exactly one or two funds: VTI (or VOO/FNILX/SWPPX if you prefer straight S&P 500 exposure) plus VXUS for international. That’s it. A two-fund portfolio at a combined expense ratio of 0.03 to 0.05% beats the vast majority of actively managed funds, financial advisors, and hedge fund managers over any 20-year period. Resist the urge to add complexity until you’ve been investing consistently for at least a year and can articulate why each new position is there.

Check your tax location. If you have both taxable and tax-advantaged accounts, put VXUS in taxable (to capture the foreign tax credit), bonds in tax-deferred (to shelter the income), and growth-oriented funds like VTI or QQQ in your Roth IRA (where the gains compound tax-free). This move, called asset location, can add 0.25 to 0.50% per year to your after-tax returns without changing your risk exposure at all.

Look at what you already own before buying anything new. I once helped someone who held VTI, VOO, and FNILX simultaneously, genuinely believing they were diversified across three funds. They owned the same 500 companies three times over. Check holdings overlap at a site like StockAnalysis before adding a new ticker. Diversification across assets is the goal, not diversification across ticker symbols.

Where Things Are Heading

Fee compression has largely played out. When FNILX already charges zero, there’s not much room left to run. The next battleground is tax efficiency, asset location tools, and direct indexing, where you own individual stocks that replicate an index and harvest tax losses at the individual security level. Schwab and Fidelity are both rolling out versions of this for larger accounts, though how much it matters for investors under $500k is still an open question. My guess is: not much, not yet.

For most people reading this, the boring truth is the same as it’s always been. Pick a cheap total market fund, add international and bonds as your risk tolerance and timeline dictate, automate your contributions, and stop checking your portfolio every day. The funds in this guide all cost less than a cup of coffee per $10,000 invested per year. The real cost isn’t the expense ratio. It’s every panicked decision you make between now and retirement.

If you’re weighing more aggressive alternatives, including cryptocurrency, alongside these index funds, our analysis of whether Bitcoin is still worth it in 2026 provides a framework for thinking about how speculative assets fit (or don’t fit) into a portfolio built on the funds above.
