Are Target-Date Funds a Good Alternative?
If you’ve ever looked at your 401(k) options or browsed through your brokerage’s retirement fund suggestions, chances are you’ve seen a fund labeled something like “Target Retirement 2055” or “Freedom Fund 2040.” These are target-date funds (TDFs)—designed to make retirement investing simple by automatically adjusting your portfolio over time.
But are they really the best choice? Or should you build your own low-cost index fund portfolio?
Let’s break down how target-date funds work, who they’re best suited for, and how they stack up against DIY investing.
What Is a Target-Date Fund?
A target-date fund is a mix of investments—usually stocks and bonds—that gradually becomes more conservative as you approach a specific “target” year, such as your retirement date.
Example:
If you’re planning to retire in 2055, you might choose a fund like Vanguard Target Retirement 2055 Fund (VFFVX). In your younger years, the fund holds mostly stocks for growth. As the years pass, it automatically shifts more into bonds to reduce risk.
Glide Path:
This gradual shift in asset allocation is called a glide path, and it’s pre-set by the fund provider. You don’t have to rebalance or adjust anything—the fund does it for you.
Pros of Target-Date Funds
Simplicity
You pick a fund once, and it handles diversification, rebalancing, and risk reduction automatically.
Broad Diversification
Most TDFs include U.S. stocks, international stocks, bonds, and sometimes even real estate or inflation-protected securities.
Perfect for “Set It and Forget It”
Ideal for retirement savers who don’t want to constantly monitor or tweak their portfolios.
Auto-Rebalancing
TDFs stay aligned with their asset allocation model—no need for manual rebalancing, which many investors forget to do.
Cons of Target-Date Funds
One-Size-Fits-All
TDFs assume that all investors retiring in the same year have the same risk tolerance—which isn’t always true.
Higher Fees Than DIY Index Portfolios
While still relatively low-cost, most TDFs charge 0.12%–0.35%. A DIY mix of index funds could cost under 0.05%.
Lack of Customization
You can’t adjust for your personal situation (e.g., pension income, early retirement plans, or a desire for more aggressive growth).
Target-Date Funds vs. DIY Index Fund Portfolios
Here’s a side-by-side breakdown:
| Feature | Target-Date Fund | DIY Index Portfolio |
|---|---|---|
| Simplicity | Very high | Moderate |
| Customization | Low | High |
| Fees | 0.12%–0.35% | 0.02%–0.10% |
| Rebalancing Required? | No | Yes |
| Best For | Hands-off investors | Active planners |
| Tax Efficiency | Good in tax-advantaged accounts | Varies |
When a Target-Date Fund Makes Sense
- You’re new to investing or don’t want to research asset allocations.
- You’re investing in a 401(k) or IRA, and a good TDF is offered.
- You want automatic diversification without needing to manage multiple funds.
TDFs shine in workplace retirement plans where convenience and automation matter. In fact, over 60% of 401(k) contributions now flow into target-date funds, according to Vanguard’s 2024 retirement trends report.
When a DIY Index Portfolio Might Be Better
- You want more control over asset allocation.
- You can tolerate some hands-on portfolio management.
- You care about minimizing fees even further.
- You have unique goals—like early retirement or retiring abroad.
A DIY portfolio using a mix like 80% VTSAX (U.S. stocks) + 20% FXNAX (bonds) can offer lower fees and more flexibility—but you’ll need to rebalance and adjust over time.
Target-Date Fund Examples for 2025
| Fund Name | Target Year | Expense Ratio | Fund Family |
|---|---|---|---|
| Vanguard Target Retirement 2060 (VTTSX) | 2060 | 0.08% | Vanguard |
| Fidelity Freedom Index 2045 (FIOFX) | 2045 | 0.12% | Fidelity |
| Schwab Target 2050 Index (SWYJX) | 2050 | 0.08% | Schwab |
These are all low-fee, well-diversified choices from trusted providers. You can invest in them through most retirement platforms.
Final Word: Which One Wins?
There’s no “one-size-fits-all” answer. But here’s the takeaway:
- If you want to set it and forget it, a target-date fund is probably the right choice.
- If you’re willing to be more hands-on and want lower fees or more customization, a DIY index portfolio may serve you better.
Both approaches are better than not investing at all—so choose the one you’ll actually stick with.
