A target-date fund automatically changes its asset allocation along a glide path toward and sometimes beyond a stated retirement or goal year.
A target-date fund (TDF) is a diversified fund that automatically changes its asset allocation along a planned glide path as a stated target year approaches and, for some funds, after it passes. The target year usually represents an expected retirement date, not a maturity date, guaranteed value, or required withdrawal date.
Target-date funds simplify allocation and rebalancing, but funds with the same year can hold different stock allocations, underlying funds, fees, risk levels, and post-retirement assumptions.
A target-date series usually offers funds at five- or ten-year intervals. A participant selects a vintage near an expected retirement year, and the manager allocates among stock, bond, cash, inflation-sensitive, and sometimes other investments.
When the target date is far away, the fund often holds more equities. As the date approaches, it generally increases allocations considered less volatile, such as bonds and cash instruments. This shift reduces some market risk but does not eliminate loss, inflation, interest-rate, credit, or longevity risk.
The manager may implement the allocation through proprietary underlying funds, unaffiliated funds, direct securities, derivatives, or a combination.
| Feature | “To” target date | “Through” target date |
|---|---|---|
| Most conservative point | Generally at the target year | Generally years after the target year |
| Common assumption | Investor may begin withdrawing or move assets near retirement | Investor may remain invested and withdraw gradually during retirement |
| Equity near target | Often lower than a comparable through fund | Often higher than a comparable to fund |
| Main question | Is the target-date allocation too conservative before a long retirement? | Is post-target equity exposure too volatile for the intended withdrawals? |
The labels do not specify exact allocations. Two “through” funds can follow materially different paths.
| Time relative to target | Fund A equity | Fund B equity |
|---|---|---|
| 20 years before | 80% | 90% |
| 5 years before | 55% | 70% |
| At target date | 40% | 60% |
| 10 years after | 40% | 35% |
Fund A is a hypothetical “to” design that stops changing at the target date. Fund B is a hypothetical “through” design that carries more equity at the target date and continues reducing it afterward.
The table is illustrative, not a recommendation or description of a specific fund. Actual glide paths can include many asset classes and can be changed by the manager under the fund documents.
Two employees both plan to retire near 2050 and each sees a fund named “Target 2050.” Fund X currently holds 88% in equities, while Fund Y holds 76%. Fund X also continues reducing equity for 15 years after 2050; Fund Y reaches its most conservative allocation in 2050.
The shared date does not make the funds equivalent. A useful comparison includes:
Selecting a year from age alone ignores outside pensions, savings, debt, withdrawal plans, risk capacity, and other household assets. This article does not determine which fund or date fits an individual.
Target-date funds are commonly structured as funds of funds. Their prospectus fee table should disclose applicable acquired-fund fees and expenses along with other operating expenses.
Underlying funds can create:
A low headline management fee should be evaluated with all disclosed fund expenses and any plan or account charges.
Retirement-plan duties, tax treatment, available funds, and investor circumstances vary. Target-date funds can lose money before, at, and after the target year.
