How long will my money last? What this calculator shows
This calculator answers one of the most important retirement questions: how long will my money last if I withdraw a set amount each year? Enter your savings, how much you plan to take out, and what you expect your investments to earn, and it shows:
- how long your savings could last, in years and months
- the age your money could run out, if you enter your age
- your starting withdrawal rate, a key measure of risk
- the total amount you'd withdraw over that time
- the yearly withdrawal that would last 30 years with your savings and return
A chart shows your balance falling over time, so you can see when the money runs low.
How to use it
- Savings or investments today: the amount you'll draw income from.
- Yearly withdrawal: what you plan to take out in the first year, before tax.
- Raise withdrawals each year by: usually your expected inflation rate, such as 3%, so your income keeps its buying power. Use 0 to keep it flat.
- Expected yearly return: a long-term average for your investments. Try a few rates, such as 4%, 5% and 6%.
- Your age (optional): to see the age your savings might run out.
Example results
At a 5% return, with withdrawals rising 3% a year:
| Savings | Yearly withdrawal | Could last about |
|---|---|---|
| $500,000 | $25,000 | 26 years 3 months |
| $500,000 | $40,000 | 14 years 9 months |
| $900,000 | $36,000 | 35 years 10 months |
| $900,000 | $72,000 | 14 years 9 months |

What is a safe withdrawal rate?
Your withdrawal rate is your first year's withdrawal divided by your savings. A commonly quoted guideline is about 4%, rising with inflation each year, which has historically given a good chance of lasting around 30 years. It's a rule of thumb, not a guarantee. Lower rates are more cautious; rates above about 5% carry a higher risk of running out.
Why results can differ in real life
- Returns vary. This calculator assumes the same return every year. Real markets go up and down.
- Timing matters. A market fall early in retirement can shorten how long your money lasts, even if average returns are the same. This is called sequence of returns risk.
- Spending changes. Many retirees spend more early on, and costs like healthcare can rise later.
- Taxes and fees reduce what you can spend, and aren't included here.
How to make your money last longer
- Withdraw a little less, especially in years when markets are down
- Keep a cash buffer of one to two years of spending
- Keep investment fees low
- Add other income, such as a pension, government benefits or part-time work
- Delay retirement, even by a year or two
Frequently asked questions
How long will my money last if I withdraw 4% a year?
At a 5% return with withdrawals rising 3% a year, a 4% starting withdrawal lasts about 36 years. At a 4% return, about 29 years.
Should I raise my withdrawals with inflation?
Usually, yes, so your income keeps its buying power. Keeping withdrawals flat makes savings last longer on paper, but your money buys less each year.
Does the calculator include government benefits or pensions?
No. Enter only what you'll withdraw from your savings, after accounting for other income.
Is my data saved?
No. The calculator runs in your browser, and nothing you enter is stored.
