How long will my money last?

Enter what you have and what you plan to spend each year. See the age your savings run out, or whether they never do.

In short: How long your money lasts depends mainly on your withdrawal rate. At a 6% return and 3% inflation, $1 million lasts about 43 years at $40,000 a year, 29 years at $50,000 and 22 years at $60,000.

Your money lasts to age 87

22 years, 3 months of $60,000 withdrawals, adjusted for inflation every year.

Withdrawal rate: 6%
Lasts forever at or below: $28,302
Runs out after: 22 years, 3 months

What would change your result

To make it last to age 95, keep withdrawals at or below $49,017 a year.
Withdraw 10% less ($54,000) and it lasts to 90.
If Social Security or a pension covers $10,000 of that spending, it lasts to 94.

A worked example

With these inputs:

Age when withdrawals start65
Portfolio at retirement$1,000,000
Yearly withdrawal$60,000
Expected return6%
Inflation3%

the calculator returns Your money lasts to age 87. 22 years, 3 months of $60,000 withdrawals, adjusted for inflation every year.

Its first suggestion: To make it last to age 95, keep withdrawals at or below $49,017 a year.

Key facts

Withdrawals that never exceed balance × r ÷ (1 + r), where r is the real return, can last indefinitely.
Withdrawing about 4% of your starting balance, adjusted for inflation, has historically lasted at least 30 years in US markets.
Bad returns early in retirement shorten the result most; this is called sequence-of-returns risk.

How it's calculated

Each year starts with your withdrawal; what remains grows at the real return. We repeat until the balance can no longer cover a full year, and count the partial year at the end.

If your withdrawal is at most balance × r ÷ (1 + r), where r is the real return, the portfolio earns at least what you take and never runs out.

Questions people ask

Why use the real return?

Your withdrawals rise with prices. Growing the portfolio at the return after inflation keeps everything in today's dollars, so $60,000 means $60,000 of today's spending power every year.

Does this include market crashes?

No. This assumes the same return every year. Bad years early in retirement shorten the result; the Monte Carlo calculator shows how much.

Should I include Social Security?

Subtract the benefits you expect from your yearly withdrawal. If they start later, run the calculator for the years before and after separately.
