Retirement fund target: Estimating a Retirement Fund from Spending
Dividing desired annual spending by an assumed withdrawal rate produces a rough fund target. It turns the spending plan into a balance that can be compared with projected savings.
Use the Retirement fund target Calculator to enter your own figures and compare the result with the worked example below.
Retirement fund target formula
Target fund = Desired annual spending ÷ Assumed withdrawal rate
Worked example
| Item | Example value |
|---|---|
| Desired annual spending | 40000 USD |
| Assumed annual withdrawal rate | 4 % |
| Retirement fund target | 1,000,000 USD |
These are illustrative inputs, not current prices, rates or recommended targets. Where a currency is shown, keep all comparable money amounts in the same currency; conversion examples identify the two sides separately.
How to interpret the result
The withdrawal rate is an assumption, not a guarantee of sustainability. Longevity, fees, taxes and the order of investment returns matter.
