Below are the median 401(k) balances by age group based on recent data from Vanguard's 2024 "How America Saves" report, which provides a comprehensive view of retirement savings trends:

Under 25: $2,816

25 to 34: $14,933

35 to 44: $35,537

45 to 54: $60,763

55 to 64: $87,571

65 and older: $88,488

These figures represent the median, which is a better indicator than the average for understanding typical savings, as it is less skewed by high-balance accounts.
