A couple in their late 50s, with most of their savings in a 401(k), may find themselves torn between locking in guaranteed income and keeping money invested for growth. That tension often boils down to a choice between an annuity and a target date fund, and the right answer is shaped as much by regulation and fees as by personal comfort with risk. I want to walk through what regulators say, what recent rule changes mean for retirement security, and how to think through whether either product truly fits.
Understanding Target Date Funds
The Authoritative SEC explains that target date funds are designed around a specific retirement year and follow a preset “glide path” that gradually shifts from stocks to bonds as that year approaches. In its investor bulletin on these funds, the agency notes that many are structured as mutual funds or ETF products, while others are collective investment trusts that are not SEC-registered, which means disclosures and oversight can differ even when the fund names look similar on a 401(k) menu. That bulletin also highlights that these portfolios typically start with a heavy equity allocation for younger savers and then systematically move toward more conservative holdings as the target date nears.
According to the same Authoritative SEC guidance, target date funds are marketed for diversification across asset classes and are widely used in workplace plans, with 401 language in the bulletin reflecting how commonly they appear as default options. A typical 2050 fund today might hold a majority of its assets in stock funds, then gradually tilt toward bonds and cash as 2050 approaches, so an investor who stays in the fund automatically gets a more conservative mix without having to trade. That kind of built-in rebalancing is a major reason they dominate many plan lineups, but it also means investors rely heavily on the specific glide path and fee structure chosen by the fund provider.
Demystifying Annuities
Where target date funds focus on market-based growth, annuities are insurance contracts that aim to turn savings into income, and the details matter. A Primary regulator explainer on variable annuities describes how these products let contract holders invest in underlying funds while adding insurance features, but it also spells out layers of fees that can add up. According to that document, typical mortality and expense risk charges run around 1 to 2 percent annually, with additional administrative fees, underlying fund expenses, and optional rider costs that can push total expense ratios into the 2 to 3 percent range before any surrender charges are considered.
The same Primary explainer notes that surrender periods can last up to 10 years, during which investors who withdraw more than a limited amount may pay substantial penalties. Those charges are layered on top of the ongoing fees, which the regulator warns can significantly erode returns over time compared with lower-cost investments. Fixed annuities, which are not the focus of that variable annuity document, are often marketed for guaranteed rates or income, but the core trade-off is similar: in exchange for some form of guarantee, the investor gives up liquidity, accepts complex fee structures, and relies on the insurer’s ability to meet its obligations.
Regulatory Safeguards for Recommendations
For anyone deciding between an annuity and a target date fund, a key development is how regulators now frame the duties of people who recommend these products. The SEC’s adopting release for Reg BI explains that when broker-dealers make recommendations to retail customers, they must act in the customer’s best interest and cannot place their own financial interests ahead of the customer’s. The SEC spells out obligations around disclosure, care, and conflict management, which are Critical for situations where a broker might earn higher compensation from selling a complex annuity than from steering a client into a relatively low-cost fund.
Retirement rollovers trigger a second layer of rules. The DOL’s guidance on PTE 2020-02 explains how advisers relying on that exemption must handle conflicts, provide specific disclosures, and document why a rollover recommendation is in the investor’s best interest, including when recommending an annuity over staying in a 401(k) target date fund. That Primary guidance is Useful for understanding that regulators expect firms to analyze costs, services, and investment options on both sides of a rollover, rather than defaulting to a higher-commission product. At the same time, the Primary DOL hub that links to the Federal Register final rule and exemption amendments also notes that a court order has stayed the rule’s effective date, which leaves some legal uncertainty even as firms move to align practices with the stated expectations.
Pros and Cons Comparison
Cost and liquidity are where target date funds often stand apart. The Authoritative SEC bulletin on these funds points out that, like other mutual funds and ETFs, they charge ongoing expense ratios, and in many large plans those fees fall in the 0.1 to 0.5 percent range. That is a small fraction of the 2 to 3 percent total expense levels described in the Primary variable annuity explainer, and target date funds typically allow investors to move money in and out of the fund daily without surrender charges. From a pure cost and flexibility standpoint, that structure tends to favor target date funds for investors who value access to their savings and want to keep more of the market’s return.
Annuities, on the other hand, are built around guarantees that can look attractive during market volatility. The Primary discussion of variable annuities emphasizes that they can offer features such as guaranteed minimum income or withdrawal benefits, which may appeal to people worried about outliving their assets. Yet that same document highlights how fees and surrender charges can erode returns, and independent research so far provides thin evidence that annuities, after costs, consistently outperform a disciplined investment strategy in diversified funds. The innovation around target date funds also continues, with reporting on BlackRock’s new private equity target date fund in 2024 showing that providers are experimenting with alternative assets inside these vehicles, which could change their risk and return profile in ways investors need to understand before comparing them with annuities.
When to Choose Each Option
For someone who wants a largely hands-off approach and is still years away from retirement, I see target date funds as a straightforward way to match risk to age while keeping fees relatively low. The Authoritative SEC bulletin explains that investors still need to check whether a fund’s glide path matches their own comfort with risk, since some funds keep higher stock exposure even after the target date while others shift more quickly into bonds. Within that structure, however, the automatic rebalancing and diversification can be especially useful for savers who do not want to manage a portfolio of individual funds.
By contrast, annuities tend to fit best for people who prioritize predictable income and are willing to trade liquidity and some growth potential for that security. The DOL’s FAQ on PTE 2020-02 stresses that advisers recommending rollovers into annuities should document why the move is in the investor’s best interest, including an analysis of fees and services. That same focus on documentation implicitly acknowledges that individual tax implications and personal circumstances can be complex and uncertain, which is why regulators press for a written rationale rather than assuming a one-size-fits-all answer. For some retirees, a partial annuity that covers essential expenses while leaving the rest in a target date fund can balance longevity protection with growth, but the right mix depends heavily on risk tolerance, health expectations, and other income sources.
State-Level Best-Interest Rules for Annuities
Beyond federal rules, state insurance regulators have reshaped how many annuity sales are supposed to work. The Primary NAIC explainer on annuity suitability describes how revisions to Model 275 added a best-interest standard for annuity recommendations, requiring agents to consider the consumer’s financial situation, insurance needs, and objectives. That document explains that the updated Model is Useful for giving states a template to hold producers to a higher standard than simple suitability when recommending annuities that are not securities.
The same Primary NAIC resource reports that states have been adopting these Model 275 revisions, and as of its latest update, more than 15 jurisdictions had put some version of the best-interest standard in place. For consumers, that means many annuity transactions now fall under both state best-interest rules and, when securities or retirement accounts are involved, federal frameworks like Reg BI and DOL exemptions. The overlapping requirements are not a guarantee of perfect advice, but they do create more avenues for regulators to challenge recommendations that appear driven by commissions rather than client needs.
Next Steps and Professional Advice
Anyone weighing a shift from a 401(k) target date fund into an annuity is facing a decision with long-term consequences, and the regulators themselves encourage investors to seek informed, independent guidance. The Primary DOL hub that links to the Federal Register materials on retirement security highlights how complex the rulemaking around advice and rollovers has become, which is one reason I view a fiduciary adviser, who is obligated to put client interests first, as a valuable ally. At the same time, the DOL’s PTE 2020-02 FAQ makes clear that even fiduciary-level advice must be backed by documentation, cost comparisons, and clear disclosure, so investors should expect and request that level of detail.
On the securities side, the SEC offers tools that can help investors evaluate products before meeting with an adviser. The Authoritative SEC bulletin on target date funds and the Primary explainer on variable annuities both walk through fee structures and risks in plain language, and the agency’s online calculators can help estimate how different expense levels affect long-term outcomes. I generally suggest that investors bring printouts or screenshots from these tools to any meeting where a rollover or annuity purchase is on the table, and ask the adviser to explain, in writing, how the recommendation aligns with Reg BI, DOL PTE 2020-02, and, for annuities, any applicable Model 275 best-interest standard. That kind of evidence-based conversation is the clearest way to decide whether keeping money in a target date fund, locking in an annuity, or combining the two is the better path toward a secure retirement.
