The Fidelity benchmarks
Fidelity publishes the most widely cited retirement-savings benchmarks in the U.S., updated annually using their data across 40 million accounts. The framework expresses savings as a multiple of current salary, much easier to internalise than absolute dollar amounts that mean different things at different incomes.
By age 30: 1x salary. By 40: 3x. By 50: 6x. By 60: 8x. By 67 (full retirement age): 10x. The numbers assume a worker who starts saving 15% of gross income (including any employer match) at age 25, earns a 7% real return on a diversified portfolio, and retires at 67. The 10x target is calibrated to replace ~80% of pre-retirement income using a 4% safe withdrawal rate plus Social Security.
Where the median American actually stands
- Median 401(k) balance for ages 25–34: approximately $14,900 (Vanguard 'How America Saves').
- Median 401(k) balance for ages 35–44: approximately $35,500.
- Median 401(k) balance for ages 45–54: approximately $60,800.
- Median 401(k) balance for ages 55–64: approximately $87,000.
- Federal Reserve SCF median retirement balance across all accounts for 55–64: ~$134,000.
- The 10x-of-salary target at 67 implies $700,000–$1,500,000 for typical income ranges, far above the median.
If you're behind, what to actually do
- Raise the savings rate. Add one percentage point every six months until you're at 20–25% of gross.
- Capture any unclaimed 401(k) match, it's an immediate 50–100% return, no other input matches it.
- Use the catch-up contributions: at 50+, the extra $7,500 in a 401(k) and $1,000 in an IRA add ~$8,500/year to your shelter.
- Delay retirement by 2–3 years. Each year of delay raises sustainable spending by roughly 6–7% (extra savings + fewer withdrawal years + larger Social Security).
- Plan to spend ~20% less in retirement than your current lifestyle. Most retirees naturally do this anyway, the data backs it up (Employee Benefit Research Institute).
- Audit fees. A 1% expense ratio costs roughly 25% of your final balance over 40 years, switch to broad index funds with sub-0.1% fees.
If you're ahead, what to actually do
Being well above the benchmarks at any age opens up options. The first is geographic and lifestyle freedom, being able to take lower-paying but more meaningful work without sweating retirement. The second is Coast FIRE: at 1.5x–2x the age benchmark, you can technically stop contributing entirely and let compounding alone hit your number by 67.
The third is sequencing optimisation. Once you're past 2x the benchmark, the highest-value tax planning becomes Roth conversions in low-income years (sabbaticals, between jobs), HSA stuffing for medical receipts, and asset-location optimisation between Traditional, Roth and taxable accounts. These moves can be worth six figures over 30 years.
Beyond the benchmarks: spending matters more
The Fidelity benchmarks are pegged to lifestyle: 10x of your current salary, not 10x of some abstract 'comfortable retirement.' The implicit assumption is that you'll continue spending roughly what you spend now. If your real retirement spending will be lower, paid-off mortgage, kids launched, no commuting, then 8x might be plenty. If it will be higher (chronic-care concerns, generous gifting plans, an expensive hobby), the benchmark is too low.
The Bengen and Trinity studies, which underpin the 4% rule, are built on real spending, not income. Re-anchor the benchmark on your projected retirement budget, not your current paycheck, and the savings target becomes both more accurate and more motivating.
Catch-up plan if you're behind by decade
Behind at 30 (under 0.5x salary): your runway is still 35+ years. Bumping savings from 7% to 15% of pay closes most of the gap by 45. Compounding does the rest. Don't panic-allocate to risky assets to 'catch up', the lever is savings rate, not return chasing.
Behind at 40 (under 2x salary): the next decade is the most important of your career. Target 20–25% savings rate including match. Max the 401(k) and an IRA. If you have kids in the house, consider deferring 529 contributions for one to two years and putting the cash into your own retirement first, kids can borrow for college, you cannot borrow for retirement.
Behind at 50 (under 5x salary): use the catch-up contributions ($7,500 in a 401(k), $1,000 in an IRA, $1,000 in an HSA), and consider Mega Backdoor Roth if your employer offers it. Plan to work to 67 or 70, every additional year of work is roughly 2 years of delayed withdrawal plus 1 year of additional contribution, a triple win.
Behind at 60 (under 7x salary): downsizing housing in retirement is often worth $200,000–$400,000 in unlocked equity. Combined with delaying Social Security to 70 (an 8% per year increase from age 67 to 70), most late starters can still retire comfortably at 70 even from a thin 401(k).
The benchmarks behind the rule of thumb
Fidelity's age-based benchmarks (1x at 30, 3x at 40, 6x at 50, 8x at 60, 10x at 67) are reverse-engineered from a few key assumptions: starting savings at 25, contributing 15% of pay including match, retiring at 67, replacing 45% of pre-retirement income from your portfolio with the rest from Social Security, and lasting 28 years in retirement. Change any of those inputs and the benchmark shifts.
T. Rowe Price uses a slightly more conservative ladder (1x at 30, 2x at 35, 3x at 40, 5x at 45, 7x at 50, 9x at 55, 11x at 60, 14x at 65) that assumes a lower replacement rate from Social Security. The Center for Retirement Research's National Retirement Risk Index finds 39% of working-age households are not on track to maintain their standard of living in retirement, make sure you're not in that 39%.
What 'salary multiple' actually counts
Use gross household income, not net. Include 401(k), Roth IRA, Traditional IRA, HSA (only if you intend to use it for medical), Roth 401(k), SEP-IRA and SIMPLE-IRA balances. Exclude home equity (you have to live somewhere), 529s (those are for kids), checking-account cash, and emergency funds.
Include taxable brokerage balances earmarked for retirement, but apply a 15% haircut because you'll owe long-term capital gains on withdrawal. A $400,000 brokerage = $340,000 effective retirement balance for benchmarking.
