Top 10 Best Index Funds for Long-Term Investors in 2026

## Frequently Asked Questions About Index Funds in 2026

Are index funds still a good idea in 2026? Yes. With over 90% of active managers trailing their benchmarks over the past 15 years (per SPIVA data referenced in the intro), low-cost index funds remain one of the most reliable ways for long-term investors to build wealth.

What expense ratio is considered low for an index fund? Anything at or below 0.10% is competitive for broad-market index funds in 2026. Several funds on this list, such as VXUS (0.07%) and FZROX (0.00%), sit at or below that threshold.

VOO vs VTI — which is better for long-term investors? VOO tracks the S&P 500 (500 large-cap U.S. companies), while VTI tracks the entire U.S. stock market (3,800+ companies, including small- and mid-cap). For broadest single-fund U.S. exposure, VTI wins; for the lowest expense ratio on large-caps, VOO wins. Many long-term investors hold both.

How long should I hold an index fund? Most of the funds on this list are designed for multi-decade holding periods. Short-term volatility is normal; the long-term wealth-building benefit comes from compounding over 10+ years.

Do index funds pay dividends? Many do. Funds such as SCHD on this list are specifically chosen for dividend income, while broad-market funds like VOO and VTI also pay quarterly dividends that can be reinvested.

Most of the funds on this list fall into one of two roles. VTI, VOO, and the Vanguard Target Retirement funds are "core" holdings — broad and diversified enough to be the entire portfolio on their own. BND, VWO, SCHD, USRT, and VXUS are "satellite" holdings — they add a specific tilt (bonds, emerging markets, dividends, real estate, international) on top of a core position, not instead of one. If you only want to own a single fund, it should come from the first group.

The expense-ratio differences across this list are small in absolute terms — the gap between the cheapest fund here (FZROX at 0%) and the priciest (several funds around 0.08%) amounts to a few dollars a year on a typical account balance. What actually separates these funds is asset class and role, not cost: a total-market fund, a bond fund, and a REIT fund aren't competing for the same dollar, they're built to do different jobs inside the same portfolio.
