64-Year-Old Retiree Taps $85,000 401(k) Yearly to Lock In 8% Social Security Gain

Q: What is the biggest risk to this plan if a retiree doesn't live into their 80s?

The biggest risk is dying before the strategy’s break-even point, which means Linda may give up lifetime income by delaying Social Security and may not fully benefit from the taxes she pays on Roth conversions. This plan is built for longevity. Delaying Social Security to 70 raises her monthly check by about 32% versus claiming at full retirement age, but that only pays off if she lives long enough—typically into the early 80s. If she dies in her 70s, she could collect less total Social Security over her lifetime than if she had claimed earlier. The same timing risk applies to Roth conversions. Linda is paying tax now to reduce future required minimum distributions and create tax-free Roth assets later. If she does not live long enough, she may not personally realize much of that long-term tax benefit. In that case, the upfront tax cost was real, while the payoff was limited. That does not mean the plan fails entirely. The 401(k) withdrawals still reduce future tax pressure, and Roth assets can still help heirs because qualified Roth withdrawals are generally tax-free and Roth accounts avoid lifetime RMDs for the original owner. But for Linda herself, the main tradeoff is clear: this strategy is strongest for someone with reasonable life expectancy, and its biggest risk is a shorter-than-expected lifespan.

$85,000 in annual 401(k) withdrawals lets 64-year-old Linda fund retirement now while delaying Social Security to 70, where her projected benefit reaches $5,181 a month.
That delay adds roughly 8% a year after full retirement age—plus a 2.8% 2026 COLA—outpacing risk-free alternatives such as a near-5% 10-year Treasury.
Over six years, the plan would draw about $510,000 from her $1.1 million traditional 401(k), still leaving several hundred thousand dollars if the remaining portfolio earns 5% to 6%.
The strategy also exploits a low-tax window: a single filer can withdraw about $63,000 and stay in the 12% federal bracket, avoiding higher taxes on later withdrawals and the $106,000 IRMAA Medicare threshold.
Linda could also convert $30,000 to $40,000 a year to a Roth IRA before 70, shrinking future required minimum distributions at 75 and leaving her Social Security check 32% above its full-retirement-age level.
