What is the Retirement Withdrawal Calculator?
See how long your retirement savings last with yearly withdrawals. To use the Retirement Withdrawal Calculator, enter savings at retirement, first-year withdrawal, return, inflation; it returns years savings last, withdrawal rate, and shows them instantly as you type.
Planning for retirement income
Retirement income usually comes from several places: workplace plans such as a 401(k), individual accounts, Social Security and sometimes a pension. Begin with the retirement calculator for the big picture and then look at each source.
How to use the Retirement Withdrawal Calculator
- Enter your numbers. The inputs are Savings at retirement ($), First-year withdrawal ($), Return (%), Inflation (%). Use today’s balances and your real contribution amounts, then test a more cautious return. Fields marked optional can stay at zero.
- Read the result. The highlighted box gives the Years savings last, and the cards below show Withdrawal rate. Tables and charts break it down further.
- Test other scenarios. Results update as you type. Change one value at a time to see what drives the answer, and press Reset to go back to the defaults.
Formula and how it works
Example with real numbers
Here is the Retirement Withdrawal Calculator using the default values shown in the calculator above:
Inputs
| Savings at retirement ($) | 900,000 |
|---|---|
| First-year withdrawal ($) | 40,000 |
| Return (%) | 5.5 |
| Inflation (%) | 2.8 |
Results
| Years savings last | 34 |
|---|---|
| Withdrawal rate | 4.44% |
With these inputs the calculator returns Years savings last: 34. Change any value in the calculator to see how the result moves.
What if you change one input?
Sensitivity check: raising Savings at retirement ($) from 900,000 to 1,080,000 (about 20% higher) and leaving everything else as in the example above changes the results like this:
| Result | Example | After the change | Change |
|---|---|---|---|
| Years savings last | 34 | 46 | +35.3% |
| Withdrawal rate | 4.44% | 3.7% | -16.7% |
The input that moves the result most is the one to check twice. Change it in the calculator above to test your own case.
What the results tell you

Frequently asked questions
How long will my savings last?
It depends on the withdrawal rate, return and inflation.
How much should I save for retirement?
Many planners suggest saving 10% to 15% of income, including employer match, starting early. The retirement calculator shows the monthly amount you need for your own goal.
When should I claim Social Security?
Claiming at 62 reduces your benefit permanently, while waiting until 70 increases it. The best age depends on your health, other income and spouse. The Social Security Calculator compares the options.
Are the results guaranteed?
