5% 401(k) Rate at Age 53 Projects Sub-30% Income Replacement by 65

MarketWatch coverage notes the need to increase savings but omits explicit modeling of salary growth, employer matches, and equity returns. IRS Form 5500 data and Vanguard 2023 How America Saves report show median contribution rates for ages 50-59 at 6.8%, with only 22% of plans offering automatic escalation above 5%. At an $85,000 salary, 5% annual contributions plus 3% real return compound to roughly $142,000 by age 65 before taxes.

Social Security replacement averages 40% for median earners per SSA actuarial tables, leaving a combined 65-70% gap versus the 80% target cited in EBRI studies. Sequence-of-returns risk is elevated for a 12-year horizon ending in 2036, when bond yields remain below historical averages. The 2024 Secure 2.0 catch-up provision raises the limit to $7,500 after 60 but does not alter base deferral behavior.

Plan sponsors report 34% of participants aged 55+ maintain deferrals below 6% even after auto-escalation, per Deloitte 2024 retirement survey. Without an immediate 3-5 percentage point increase, drawdown pressure on remaining assets rises sharply after age 75.
