What 401(k) Percentiles by Age Reveal
Retirement savings benchmarks grouped by age percentile let workers see how their 401(k) balance compares with others in the same stage of life. The figures come from large aggregated datasets, typically from retirement-plan recordkeepers or survey research, and they help people judge whether their savings trajectory is on track. Because individual circumstances vary widely, these percentiles are best used as context, not as a verdict on financial health.

How Percentile Ranges Are Constructed
Analysts sort 401(k) balances into percentiles — typically the 10th, 25th, median (50th), 75th, and 90th — within narrow age bands. The underlying data usually includes only participants with a balance in a defined-contribution plan, so it skews toward people who have access to an employer-sponsored account. Missing from these tables are workers who never joined a plan or who held only short-term jobs with no retirement benefit.
Typical 401(k) Balance Ranges by Age Group
Below is a generalized snapshot of what the mid-2020s data from major recordkeepers and research firms often looks like. Exact figures shift each year and by source, so treat these as reference points rather than fixed thresholds.
| Age Range | 10th Percentile | 25th Percentile | Median | 75th Percentile | 90th Percentile |
|---|---|---|---|---|---|
| 20–29 | Under $5,000 | $5,000–$10,000 | $10,000–$20,000 | $20,000–$40,000 | $40,000+ |
| 30–39 | $5,000–$10,000 | $15,000–$30,000 | $30,000–$60,000 | $60,000–$120,000 | $120,000+ |
| 40–49 | $15,000–$30,000 | $40,000–$80,000 | $80,000–$160,000 | $160,000–$300,000 | $300,000+ |
| 50–59 | $30,000–$60,000 | $80,000–$150,000 | $150,000–$300,000 | $300,000–$600,000 | $600,000+ |
| 60–69 | $50,000–$100,000 | $120,000–$250,000 | $250,000–$500,000 | $500,000–$1,000,000 | $1,000,000+ |
Factors That Pull a Balance Up or Down
A worker at the 25th percentile is not necessarily behind; they may have started late, taken career breaks, or worked for employers without generous matching. Conversely, someone at the 90th percentile may carry high-cost debt or face a volatile industry. The biggest levers are years of contributions, employer matching, investment returns, and fees — not age alone.
Why the Median Often Understates Readiness
The median balance omits the impact of future Social Security and pension income. For a household expecting a substantial pension, a 401(k) balance in the 25th percentile may still support a comfortable retirement, while a high earner at the 75th percentile with no pension might feel less secure. Plans that include annuities or other guaranteed income shift the picture of what a given balance actually means.
Using the Data to Set a Savings Target
Instead of chasing a specific dollar amount at a given age, workers should anchor their savings rate to replacement income goals. A common guideline is to save 15% of pre-tax income, including employer contributions, starting by the mid-20s. Someone behind the median can use the gap to calculate the higher rate needed to catch up. Automated annual increase features in 401(k) plans help close that gap without requiring constant attention.
Limitations of 401(k) Percentile Data
These datasets exclude balances rolled into IRAs, balances left in former employer plans, and nonparticipants. They also do not adjust for cost-of-living differences, household size, or defined-benefit pension wealth. As a result, the percentiles describe a subset of the workforce and should be combined with personal budgeting and professional advice.
Where to Find Updated Percentile Tables
Major sources include the Employee Benefit Research Institute, Fidelity, Vanguard, and the Transamerica Center for Retirement Studies. Each publishes annual or quarterly snapshots with slightly different methodologies, so comparing two or three sources gives a more complete picture.
