Best ETFs for a Three-Fund Portfolio
The three-fund portfolio is the gold standard of simple investing. Here are the best ETF picks from every major provider.
Don't have time? Here's what you need to know:
- 1VTI + VXUS + BND is the classic three-fund portfolio — 15,000+ holdings, ~$4 per $10K in annual fees
- 2Every major provider (Vanguard, iShares, Schwab, Fidelity) offers equivalent three-fund options
- 3A typical allocation: 60% U.S. stocks, 25% international, 15% bonds — adjust bonds upward with age
- 4The three-fund portfolio has built more millionaires than any complex strategy
Why Three Funds Cover Everything
The three-fund portfolio holds one U.S. stock fund, one international stock fund, and one bond fund. Together, these three positions cover over 15,000 stocks and thousands of bonds across 40+ countries. The concept was popularized by Vanguard founder John Bogle and the Bogleheads investing community. It works because broad diversification, low fees, and consistent contributions beat complex strategies for the vast majority of investors.
The beauty is its simplicity: three purchases, one annual rebalance, and total fees under $10 per $10,000 per year. Thousands of millionaires and early retirees have built wealth using nothing more than this approach.
Three-Fund Options by Provider
All four providers offer functionally identical three-fund portfolios at nearly the same cost. Fidelity's mutual fund versions are marginally cheaper. Vanguard's ETFs are the most widely recommended and discussed. Pick the provider your broker makes easiest to use.
| Role | Vanguard | iShares | Schwab | Fidelity (MF) |
|---|---|---|---|---|
| U.S. Stocks | VTI (0.03%) | ITOT (0.03%) | SCHB (0.03%) | FSKAX (0.015%) |
| International | VXUS (0.07%) | IXUS (0.07%) | SCHF+SCHE (0.06-0.11%) | FTIHX (0.06%) |
| Bonds | BND (0.03%) | AGG (0.03%) | SCHZ (0.03%) | FXNAX (0.025%) |
| Blended Cost | ~0.04% | ~0.04% | ~0.04% | ~0.03% |
How to Split the Three Funds
Common allocation for a 30-year-old: 60% U.S. stocks + 25% international stocks + 15% bonds. Adjust bonds upward as you age (roughly your age minus 20 as bond percentage). Adjust international between 20-40% based on your preference for global diversification.
The exact split matters less than sticking with it. A 60/25/15 portfolio and a 70/20/10 portfolio produce similar long-term results. Consistency and low fees are the real drivers of wealth, not the precise allocation percentages.
Tip: If choosing between VTI and VOO for the U.S. slot, either works. VTI is technically more diversified (4,000 vs 500 stocks). VOO is the most recognized benchmark. Performance difference is negligible.

Frequently Asked Questions
Can I mix providers? (VTI + IXUS + SCHZ)
Absolutely. ETFs from different providers trade on the same exchanges and can be held in the same brokerage account. Mix and match to get the lowest fee for each position. There is no requirement to use a single provider.
When should I upgrade from three funds to more?
Most people never need to. The three-fund portfolio covers 95%+ of what matters. If your portfolio exceeds $100,000 and you want to add REITs, dividend growth, or factor tilts, those are optional enhancements — not upgrades.
Is the three-fund portfolio good enough for retirement?
Many people have retired successfully using nothing but a three-fund portfolio. As you approach retirement, shift the bond allocation higher (40-60%) for more stability. The same three funds serve you from age 25 to 95 — only the proportions change.
