American workers in their 30s are holding steady with their 401(k) contributions, even though their balances have dipped due to market volatility so far in 2025.
That’s according to Fidelity, the largest retirement plan provider in the U.S., which manages more than 24 million 401(k) accounts. Its latest quarterly study breaks down average 401(k) balances by age group for the three months ending March 31.

The year is off to a rough start, with average 401(k) balances for workers in their 30s declining by roughly 2% in the first quarter, according to data provided by Fidelity.
However, this age group has been relatively diligent in saving. Those ages 28 to 44 save an average of 13.5% of their pretax income, Fidelity reports, which is close to its recommended savings rate of 15%.
