Annuities in 401(k) Plans Aren’t All Their Cracked Up to Be

Key Takeaways

• 83% retirees face unexpected expenses annually
• Typical emergency cost equals 10% of income
• Needed retirement fund: $200k‑$400k
• Only 28% hold $200k‑$5M assets for annuities
• Annuities lack inflation indexing, reducing attractiveness

Summary

A new study from the Center reveals that 83% of retirees encounter unexpected expenses each year, averaging about 10% of their annual income. To cover such shocks over a 25‑year retirement, households need an emergency fund ranging from $200,000 to $400,000. Only 28% of retirees possess the $200,000‑$5 million asset base where annuities become viable, limiting the market for 401(k) annuity options. Moreover, annuities often lack inflation indexing, further reducing their appeal as a default investment choice.

Pulse Analysis

Retirement planners are increasingly confronting the reality that unexpected expenses are the norm, not the exception. The Center’s analysis of two decades of Health and Retirement Study data shows that nearly every senior household will face a financial shock—whether a car repair, family emergency, or health care cost—within a given year. This translates to roughly one‑tenth of annual earnings, compelling retirees to amass sizable cash buffers. Traditional 401(k) structures, which often default to annuity products, may not accommodate such liquidity needs, especially when the annuity market is constrained to a narrow slice of high‑net‑worth participants.

Annuities have long been marketed as a safeguard against longevity risk, yet their design inherently transfers wealth from early‑deceased, lower‑paid participants to those who outlive expectations. Coupled with the fact that most annuities are not indexed to inflation, retirees risk eroding purchasing power over long horizons. For the average retiree earning $85,000, the study suggests a $212,500 emergency reserve, while higher earners may need upwards of $437,500. These figures dwarf the typical balance in many 401(k) accounts, underscoring the mismatch between product offerings and actual cash‑flow requirements.

For employers and fiduciaries, the implication is clear: a one‑size‑fits‑all annuity default may expose participants to inadequate flexibility and higher out‑of‑pocket costs during emergencies. Instead, plan designs should incorporate diversified investment options, including liquid cash‑equivalents and low‑cost index funds, alongside optional annuity riders for those who value guaranteed income. Financial advisors must also recalibrate recommendations, emphasizing emergency fund adequacy before locking assets into illiquid annuity contracts. By aligning retirement plans with realistic expense patterns, the industry can better serve the 83% of seniors who regularly confront unforeseen financial demands.
