For years, target-date funds have been one of the simplest tools in retirement saving. Pick the fund closest to your expected retirement year, keep contributing, and let the fund gradually become more conservative as you age. For many 401(k) investors, that simplicity has been the appeal.
But target-date funds may be entering a new phase.
More retirement plan providers are beginning to add annuity-like features to target-date strategies, designed to help participants turn retirement savings into lifetime income. Morningstar recently reported that target-date strategies with annuity components have grown sharply, with assets reaching roughly $42–44 billion by early 2026. The trend received an even bigger signal when Vanguard announced its first new target-date series in more than two decades, one that includes a built-in lifetime income option.
So what does that actually mean?
In practice, these products are trying to solve a real problem: retirement savers do not just need to accumulate money; eventually, they need to turn that money into a reliable paycheck. Annuities can help address longevity risk — the risk of outliving your savings — by creating a stream of income that lasts for life.
But the mechanics matter.
Some target-date strategies use income annuities, where a portion of the account may eventually be converted into guaranteed lifetime payments. Others use guaranteed lifetime withdrawal benefits, where the investor remains invested but pays for a guarantee that allows a certain level of lifetime withdrawals. These structures are not identical, and the tradeoffs can be significant.
The potential benefit is clear: more predictable income in retirement, less pressure to sell investments during market downturns, and a more pension-like experience for workers who do not have traditional pensions.
The downside is that this adds complexity to a product category whose greatest strength has always been simplicity. Depending on the design, investors may face higher fees, reduced liquidity, insurer-related risks, less flexibility around taxes and withdrawals, and payout terms that may be difficult to compare. In some cases, the cost of the guarantee is explicit; in others, it is embedded in the annuity payout itself. Morningstar notes that evaluating these products requires looking beyond normal fund metrics to factors like fees, liquidity, insurer strength, payout structure, and participant understanding.
That last point is important. A target-date fund is often treated as a “set it and forget it” investment. But adding an annuity feature can turn it into something closer to a retirement income contract. That does not make it bad. It does mean participants need to understand what they are getting — and what they may be giving up.
The bottom line: annuity-embedded target-date funds may become an important retirement planning tool. But they should not be evaluated on marketing language alone. Guaranteed income can be valuable, especially for retirees who want a stable income floor. Still, decisions about liquidity, taxes, survivor needs, inflation, and legacy goals should be made carefully.
Before relying on any retirement income feature inside your 401(k), make sure you understand how it works and whether it fits your broader financial plan.
