Vanguard 2023 Data Records Median 401(k) Balance at $71,000 with Top Decile Holding 60 Percent of Assets
Record 401(k) levels mask widening dispersion by income and age, with market returns substituting for wage-driven accumulation. Primary data from Vanguard and the Federal Reserve show the top income decile capturing most asset growth while lower earners remain near contribution floors. Future balance trajectories hinge on equity performance and the uptake of new auto-features rather than broad income gains.
Plan design changes expected in 2025 include expanded auto-escalation defaults and emergency withdrawal provisions under SECURE 2.0. These adjustments will test whether participation gains translate into sustained balance growth or simply accelerate leakage during volatility.
Vanguard: Median 401(k) balance growth will turn negative for the bottom income quartile if the S&P 500 closes 2025 below 5,200.
