The Three-Fund Portfolio for Beginners
Three funds, entire global market. The three-fund portfolio is the gold standard of simple investing. Here is how to set it up.
Don't have time? Here's what you need to know:
- 1VTI + VXUS + BND = entire global stock and bond market for about $5 per $10K per year
- 2Adjust the bond percentage as you age: roughly your age minus 20
- 3Rebalance once per year by directing new money to the underweight fund
- 4The three-fund portfolio has been the default recommendation of financial experts for decades
The Three-Fund Portfolio: 15,000+ Holdings, Three Purchases
The three-fund portfolio holds one U.S. stock fund, one international stock fund, and one bond fund. The most popular combination: VTI (total U.S. market), VXUS (total international), and BND (total U.S. bond market). Together they hold over 15,000 stocks and thousands of bonds spanning 40+ countries. Total cost: about $5 per $10,000 invested per year.
This portfolio was popularized by John Bogle (founder of Vanguard) and the Bogleheads community. Thousands of early retirees, millionaires, and financial advisors use some version of it. The logic: you own everything, you pay almost nothing in fees, and the returns take care of themselves.
Allocation: One Size Does Not Fit All
These are guidelines, not rules. Someone at 50 with a pension and paid-off house can afford more stock exposure than these numbers suggest. Someone at 30 who cannot sleep when the market drops 15% should hold more bonds than 10%. Adjust to your actual situation.
| Age | VTI (U.S. Stocks) | VXUS (Intl Stocks) | BND (Bonds) |
|---|---|---|---|
| 25 | 65% | 25% | 10% |
| 30 | 60% | 25% | 15% |
| 40 | 50% | 20% | 30% |
| 50 | 40% | 15% | 45% |
| 60 | 30% | 10% | 60% |
Maintaining It: 30 Minutes Per Year
Set up automatic monthly purchases in your target ratio. Once a year — pick your birthday, New Year's, or any memorable date — open your accounts and check the allocation. If any fund has drifted more than 5% from target, direct your next few months of purchases toward the underweight fund until the balance is restored.
In tax-advantaged accounts (Roth IRA, 401k), you can sell and rebuy to rebalance without tax consequences. In taxable accounts, rebalance by directing new money rather than selling to avoid triggering capital gains. The entire annual maintenance process takes about 30 minutes.
Tip: Keep a simple spreadsheet or use a free tool like Empower (formerly Personal Capital) to see your combined allocation across all accounts. View the total picture, not each account in isolation.

Frequently Asked Questions
Is the three-fund portfolio good enough forever?
For most people, yes. Professional endowments and pension funds use more complex strategies, but individual investors who stick with a three-fund approach and contribute consistently tend to outperform those who chase complex strategies. Simplicity and consistency beat sophistication and intermittent effort.
Can I use Schwab or Fidelity funds instead of Vanguard?
Absolutely. Schwab equivalents: SWTSX (U.S.), SWISX (international), SWAGX (bonds). Fidelity: FSKAX (U.S.), FTIHX (international), FXNAX (bonds). The ETF versions work too. Any low-cost total market fund serves the same purpose.
Should I add a fourth fund?
Not until your portfolio exceeds $100,000 and you have a specific reason. REITs, dividend funds, or small-cap value are common fourth additions — but they add complexity and overlap with VTI. The three-fund portfolio covers 95%+ of what matters.
