Target Date Fund Guide
Target date funds automatically adjust their asset allocation from growth-oriented to income-oriented as a specified retirement date approaches. They offer a complete portfolio in a single fund, making them the default choice in most employer-sponsored retirement plans.
A target date fund is structured around a specific year, such as 2030, 2040, or 2060, corresponding to the investor's expected retirement year. The fund uses a glide path that starts with a high allocation to stocks (typically 85-90%) decades from retirement and gradually shifts toward bonds and cash as retirement nears. The Vanguard Target Retirement 2060 Fund (VTTSX) currently holds about 90% in stocks and 10% in bonds, while the Vanguard Target Retirement 2025 Fund (VTTVX) holds roughly 60% stocks and 40% bonds.
The primary advantage of target date funds is simplicity. An investor needs only one fund to achieve a globally diversified portfolio across stocks and bonds. The Fidelity Freedom Index 2040 Fund (FBIFX) invests in underlying Fidelity index funds covering U.S. stocks, international stocks, U.S. bonds, and international bonds, all rebalanced automatically. The expense ratios for target date index funds are remarkably low, with Vanguard's series charging about 0.08% annually, compared to 0.30-0.75% for actively managed target date series.
Glide Path Variations and Criticisms
Different fund families use different glide paths. Vanguard's glide path is relatively conservative, reaching a 50/50 stock/bond split at retirement and then stabilizing at roughly 30/70 about 7 years after retirement. Fidelity's Freedom Index series is slightly more aggressive, maintaining a higher equity allocation throughout. The T. Rowe Price Retirement series uses a through-retirement glide path that continues to de-risk for several years after the target date. These differences matter: a Vanguard 2030 fund might hold 60% stocks while a T. Rowe Price 2030 fund holds 70%.
Critics note that target date funds take a one-size-fits-all approach that may not match an individual's risk tolerance, other assets, or retirement income needs. An investor with a pension, for example, may want a more aggressive target date fund than someone with no guaranteed income. The age-based approach does not account for personal factors. Nevertheless, for investors who prefer a hands-off approach, target date funds remain an excellent default choice, particularly in 401(k) plans where the Vanguard Institutional Target Retirement funds are among the most popular options.
FAQs
Which target date year should I choose?
Choose the fund closest to the year you expect to retire (age 65). A 30-year-old today would choose a 2060 or 2065 fund. If you prefer more or less risk, you can pick an earlier or later date. Choosing a 2030 fund when you plan to retire in 2050 will result in a very conservative portfolio.
Are target date funds only for retirement accounts?
They are designed for retirement but can be used in taxable accounts. However, they are less tax-efficient than holding separate funds because they rebalance frequently and distribute capital gains. They are best suited for tax-advantaged accounts like 401(k)s and IRAs.
What happens after the target date passes?
The fund continues to adjust its allocation for several years after the target date, eventually settling at a static retirement allocation (typically 20-40% stocks, 60-80% bonds). This allocation is designed to provide income while preserving capital throughout retirement. The fund does not liquidate after the target date.
