US Retirement Savings Shift by Age

In the US, retirement-account participation started near half under 35, climbed to ~60% through ages 35-54, then gradually eased in later decades.
Among account holders, median balances began just under $19K before 35, topped 2x that by 35-44, and kept building during peak earning years.
Later-life participation fell back toward half, and 75+ dropped to the low-40% range, largely reflecting rollovers and drawdowns once people stop working.
Age comparisons can motivate or discourage, because income, housing costs, family needs, workplace-plan access, and other resources all shape how much people save.
Best use of age benchmarks: focus on progress, not comparison. Starting early helps, but boosting contributions at any working stage can still improve outlook.
