How Much Should You Save for Retirement by Age?

Two rules of thumb turn 'enough for retirement' into a number you can track: the salary-multiple benchmarks (1× by 30, 10× by 67) and the 4% rule (save 25× the annual income you want). Here's how to use both.

Key takeaways

  • Rough benchmarks: 1× salary saved by 30, 3× by 40, 6× by 50, 10× by 67.
  • The 4% rule: to draw $40k/year from savings, target about 25× that — roughly $1M.
  • Contribution rate, starting early, and capturing the full employer match matter most.
  • If you're behind, raising your monthly contribution is the fastest fix — it's rarely too late.

There's no single number that means 'enough for retirement,' but there are useful checkpoints. This guide covers the two rules of thumb worth knowing — the multiple-of-salary benchmark and the 4% rule — and how to turn them into a target you can actually track.

The salary-multiple benchmarks

Fidelity's widely-cited guideline expresses savings as a multiple of your salary at each age. They're rough, but they make an abstract goal concrete:

  • By 30: about 1× your salary saved.
  • By 40: about 3× your salary.
  • By 50: about 6× your salary.
  • By 60: about 8× your salary.
  • By 67: about 10× your salary.

If you're behind, don't panic — these assume saving from your early twenties. The lever that matters most is your monthly contribution rate, and it's rarely too late to raise it.

The 4% rule: how much your savings can pay you

The 4% rule estimates sustainable retirement income: withdraw 4% of your starting balance in year one, then adjust for inflation each year, and the money has historically lasted 30 years in most market scenarios. Flip it around and it becomes a target — to draw $40,000 a year from savings, you need roughly 25× that, or about $1 million, on top of Social Security.

What actually moves the number

Three things dominate the outcome: how much you contribute, how early you start, and the employer match you capture. Time does the heavy lifting — a dollar invested at 25 can become far more than a dollar invested at 45, because it compounds for two extra decades. Capturing a full 401(k) match is free money that accelerates everything.

Turn it into a plan

Use the retirement and 401(k) calculators below to project your own path: enter your current savings, monthly contribution, and expected return to see where you land by your target age, and the monthly income the 4% rule suggests it could provide. Then stress-test it at a lower return — if the plan still works at 5%, it's robust.

Frequently asked questions

How much do I need to retire?

A common target is 25× your desired annual spending from savings — the inverse of the 4% rule. Wanting $40,000 a year from your portfolio implies roughly $1 million, on top of Social Security. Fidelity's simpler benchmark is about 10× your final salary by age 67.

What if I started saving late?

Focus on your contribution rate rather than the age benchmarks, which assume saving from your twenties. Maxing the employer match, using catch-up contributions after 50, and raising your savings rate with every raise can close a surprising amount of ground in 15–20 years.

Should I count Social Security in my target?

Yes, as a separate layer. For middle earners, Social Security replaces roughly 30–40% of pre-retirement income. Estimate your benefit from your SSA statement and treat your savings as the top-up that covers the rest of your desired income.
