Target-Date Fund
Quick Definition
A mutual fund that automatically adjusts its asset allocation from aggressive to conservative as the target retirement date approaches.
What Is Target-Date Fund?
A target-date fund (TDF) is an "all-in-one" retirement investment that automatically adjusts its asset allocation over time, becoming more conservative as you approach your target retirement year.
How It Works:
- Choose fund based on expected retirement year (e.g., 2055 Fund)
- Fund starts aggressive (heavy stocks)
- Automatically shifts to conservative (more bonds)
- "Glide path" continues into retirement
Glide Path Example (Vanguard Target 2055):
| Years to Retirement | Stocks | Bonds |
|---|---|---|
| 30+ years | 90% | 10% |
| 20 years | 85% | 15% |
| 10 years | 70% | 30% |
| At retirement | 50% | 50% |
| 7 years after | 30% | 70% |
Key Benefits:
- Simplicity: One fund for entire portfolio
- Automatic Rebalancing: No manual adjustments needed
- Diversification: Holds thousands of securities
- Professional Management: Experts handle allocation
- Set and Forget: Ideal for hands-off investors
Types:
- "To" Funds: Reach most conservative at retirement
- "Through" Funds: Continue adjusting after retirement
Major Providers:
| Provider | Fund Family | Expense Ratio |
|---|---|---|
| Vanguard | Target Retirement | 0.08% |
| Fidelity | Freedom Index | 0.12% |
| Schwab | Target Index | 0.08% |
| T. Rowe Price | Retirement | 0.55% |
Considerations:
- Higher expense ratios than DIY portfolios
- Glide paths vary by provider
- One-size-fits-all may not fit your situation
- Check underlying holdings
Ideal For:
- 401(k) default investment
- Hands-off investors
- Those who want professional allocation
- People who won't rebalance on their own
Not Ideal For:
- Active investors
- Those with specific allocation preferences
- People who want tax-location optimization
