The earliest age you could retire

Age 64

Retiring at 64, you would have about $796,129 in today's dollars, enough to spend $61,432 a year until age 95, with Social Security covering $24,852 a year from 67. Each year you wait adds savings and shortens the years the money has to cover.

All figures in today's dollars, using a steady 3.9% return after inflation. Social Security is assumed to start at 67 at the amount you enter. Taxes are not included. This is a planning estimate, not advice.

How this calculator works

Enter your age, what you have invested, what you add each month and what you expect to spend in retirement. The spending default is the average for US households aged 65 and over.

For every possible retirement age from 45 to 75, the calculator grows your savings to that age, then spends it down, counting Social Security from 67, and checks whether the money lasts until the age you plan for.

The earliest age that works is your answer. The bars and table show how much difference a few more working years make.

FormulaNest egg at age R = savings grown at the real return + monthly investments; it must cover (spending − Social Security) every year until the plan age

Common questions

What is the average retirement age in the US?

Most Americans retire in their early 60s, and many earlier than they planned because of health or job changes. Planning for a range of ages, not one, is safer.

Why plan for money to last until 95?

A 65-year-old today has a good chance of living past 85, and for couples, one partner often reaches the 90s. Running out of money late in life is the risk most worth avoiding.

When should I claim Social Security?

You can claim from 62 with a smaller check, or wait until 70 for a larger one. The calculator assumes 67, the full retirement age for most people working today. Your own estimate is at ssa.gov.

Why does each extra year help so much?

Working one more year adds a year of savings and growth, and removes a year the savings must pay for. Both move in your favor at once.

Are the numbers in today's dollars?

Yes. The calculator uses the return after inflation, so every amount is in what money buys today.
