Fidelity Reports Record Average 401(k) Balance of $155,800 for Q2 2026
Fidelity's Q2 2026 data covering 25.8 million participants shows the average 401(k) balance reached $155,800 as of June 30, a 10.5% quarterly gain and the strongest quarterly growth since Q4 2020. Fidelity attributes the increase to both stock market performance and a record employee contribution rate of 9.6%, but does not quantify how much each factor contributed to the balance change. The report also omits a median balance figure, meaning the $155,800 average does not reflect what a typical participant held.
