How Target-Date Retirement Funds Work: A Beginner’s Guide to Retirement Investing
This article is provided for general educational and informational purposes only and is not individualized investment, financial, tax, or legal advice. All investments involve risk, including the possible loss of principal.
If you are new to retirement investing, choosing investments for a 401(k) or IRA can feel overwhelming. How much should be in stocks? How much in bonds? When should you rebalance? And should your investments change as you get closer to retirement?
A target-date retirement fund is designed to simplify many of those decisions. It combines multiple investments into one fund, automatically rebalances its portfolio, and generally becomes more conservative as its target retirement year approaches.
Here is how target-date retirement funds work, what happens behind the scenes, and what beginners should know before choosing one.
You may see funds with names such as:
- Target Retirement 2040
- Target Date 2050
- Target Retirement 2060
- Target Retirement 2065
The year is a planning reference—not a requirement that you retire that year.

How Do Target-Date Funds Work?
| Question | Quick Answer |
|---|---|
| What does it invest in? | Usually a mix of stock and bond funds |
| Does it rebalance? | Generally, yes |
| Does the allocation change? | Yes, according to its glide path |
| Can it lose money? | Yes |
| Does it end at the target date? | Usually, no |
| Is the return guaranteed? | No |
Think of a target-date fund as a portfolio inside one fund.
Depending on the fund, it may provide exposure to:
- U.S. stocks
- International stocks
- U.S. bonds
- International bonds
- Short-term or cash-like investments
Instead of selecting and maintaining all of these investments yourself, the fund manages the mix according to its stated strategy.
This built-in diversification is one reason target-date funds can appeal to beginners. If this concept is new to you, our guide to how to diversify your investments explains why spreading money among different investments can help manage risk.
How Do You Choose a Target Retirement Year?
A common starting point is estimating the year you expect to retire.
Suppose someone is 30 years old in 2026 and expects to retire around age 65.
30 + 35 years = approximately 2061
That investor might start by examining a 2060 or 2065 target-date fund.
But the closest year is not automatically the right investment. Investors should also consider the fund's risk, fees, underlying investments, and asset allocation.
What Is a Target-Date Fund Glide Path?
The glide path is the planned way a target-date fund changes its investment allocation as retirement approaches.
Someone decades from retirement generally has more time to recover from market downturns, so many target-date funds begin with substantial stock exposure. As retirement gets closer, the fund typically shifts toward a larger allocation to bonds and other relatively conservative investments.
Here is a simplified hypothetical example:
| Time Until Retirement | Stocks | Bonds/Other |
|---|---|---|
| 30+ years | 90% | 10% |
| 20 years | 85% | 15% |
| 10 years | 70% | 30% |
| At retirement | 50% | 50% |
| After retirement | 35% | 65% |
These percentages are illustrative only. Actual allocations vary significantly between funds.
This changing mixture is known as asset allocation. For a deeper explanation, see our beginner's guide to what asset allocation is and why it matters.
Do Target-Date Funds Automatically Rebalance?
Generally, yes. Automatic portfolio rebalancing is one of their important features.
Imagine a fund wants to maintain 80% stocks and 20% bonds. After strong stock-market performance, the allocation might drift away from those targets.
The fund can rebalance its portfolio according to its strategy instead of requiring the individual investor to decide what to buy and sell.
This is why target-date funds are sometimes described as a hands-off retirement investment.
For people who believe they need substantial savings before they can begin investing, it may also help to understand the considerations involved when deciding whether to invest small amounts or wait until you have more money.
What Happens When a Target-Date Fund Reaches Its Date?
A common misconception is that a 2050 fund somehow expires in 2050.
It generally doesn't.
The fund does not necessarily sell everything or automatically turn the investor's account into cash when the target year arrives.
There are also two general approaches to glide paths:
“To” retirement: The fund reaches its intended long-term allocation around the target retirement date.
“Through” retirement: The fund continues adjusting its investments for years after the target date.
Two funds with “2050” in their names could therefore behave differently.
Can You Lose Money in a Target-Date Fund?
Yes.
Target-date retirement funds are investments, and their values can rise or fall. Stocks can experience significant market declines, and bonds carry risks as well.
Even a target-date fund approaching retirement can lose money.
A fund becoming more conservative does not mean it becomes risk-free. The purpose of the glide path is generally to reduce certain investment risks over time—not eliminate the possibility of loss.
Are Target-Date Funds FDIC Insured?
A target-date mutual fund is not the same thing as an FDIC-insured bank deposit.
FDIC insurance generally applies to qualifying deposit products at insured banks, subject to applicable rules and limits. Investment funds can fluctuate in value, and investors can lose principal.
This distinction is especially important for beginners who associate retirement accounts with guaranteed savings accounts.
Target-Date Fund vs. Index Fund
Target-date funds and index funds are not necessarily competing concepts. Some target-date funds actually use index funds as their underlying investments.
| Feature | Target-Date Fund | Individual Index Fund |
|---|---|---|
| Diversified portfolio | Usually across multiple asset classes | Depends on index |
| Automatic rebalancing | Generally | Not necessarily |
| Allocation changes with age | Designed to | Usually not |
| Investor involvement | Lower | Potentially higher |
| Retirement-specific strategy | Yes | Not necessarily |
Someone building a portfolio from individual index funds generally has more responsibility for determining asset allocation and rebalancing.
Target-Date Fund vs. Managing Your Own Portfolio
The major tradeoff is simplicity versus control.
A target-date fund handles many investment-allocation decisions automatically. A do-it-yourself investor can choose exactly how much to place in U.S. stocks, international stocks, bonds, and other investments.
Neither approach removes investment risk.
Investors may also hold assets outside retirement funds. For example, someone considering real estate would need to learn how to determine whether a rental property will cash flow and consider expenses, financing, maintenance, vacancies, and management responsibilities.
Beginners exploring real estate can also compare turnkey rentals versus fixer-uppers or learn about active strategies such as the BRRRR method of buying, renovating, renting, refinancing, and repeating. These approaches require very different levels of work and risk than a hands-off target-date fund.
How Much Do Target-Date Funds Cost?
Check the fund's expense ratio, which represents annual operating expenses as a percentage of assets.
For a simplified illustration:
- 0.10% = about $10 per $10,000 invested annually
- 0.50% = about $50 per $10,000
- 0.75% = about $75 per $10,000
This example only illustrates the expense-ratio calculation. Actual costs and investment results depend on the specific investment and account.
Fees matter because even relatively small differences can add up over a long retirement-investing timeline.
Common Target-Date Fund Mistakes
Beginners should avoid assuming:
- Every fund with the same target year is identical.
- The target year guarantees the fund is appropriate.
- A target-date fund cannot lose money.
- The fund becomes cash at retirement.
- Fees don't matter.
- Adding several other investments will automatically improve diversification.
That last point is important. Adding other funds to a target-date fund can change the overall asset allocation and potentially create overlapping investments.
How to Choose a Target-Date Fund
Before investing, consider this checklist:
- Estimate your expected retirement year.
- Review funds with nearby target dates.
- Check the current stock/bond allocation.
- Understand the fund's glide path.
- Determine whether it invests “to” or “through” retirement.
- Review its underlying investments.
- Compare expense ratios and applicable fees.
- Consider your risk tolerance and time horizon.
- Read the fund prospectus and other available disclosures.
Retirement year is a useful starting point, but it should not be the only consideration.
Bottom Line: How Target-Date Retirement Funds Work
Target-date retirement funds are designed to make retirement investing for beginners simpler by combining diversification, asset allocation, automatic rebalancing, and a gradually changing investment mix into one fund.
Their simplicity, however, should not be confused with a guarantee.
Before selecting a target-date fund, understand its glide path, expense ratio, stock and bond allocation, underlying investments, risk level, and strategy after retirement. Two funds with the same target year can be quite different.
The goal isn't simply to pick the year closest to your expected retirement date. It is to understand what you are investing in and whether the fund's strategy aligns with your broader retirement plan.
