This calculator is an estimate only. Actual results depend on market returns, taxes, fees, and withdrawal timing.
How to Use the How Long Will My Money Last Calculator
Step 1: Enter Your Starting Balance
Input the total amount you currently have saved or invested. This serves as the starting balance for the projection.
Step 2: Enter Your Withdrawal Amount
Specify how much money you plan to withdraw on a regular basis. This can represent living expenses, retirement income needs, or any recurring withdrawals.
Step 3: Select Your Withdrawal Frequency
Choose how often you plan to withdraw funds. The calculator uses this schedule when estimating how quickly your balance may decline.
Step 4: Enter Your Expected Annual Return
Add the annual rate of return you expect your savings or investments to earn. Investment growth can help extend the life of your portfolio.
Step 5: Enter Your Annual Inflation or Withdrawal Increase
If you expect your spending to rise over time, enter an inflation or withdrawal increase percentage. The calculator will factor this into future withdrawals.
Step 6: Set a Calculation Limit
Choose the maximum projection period. This determines how far into the future the calculator will model your savings and withdrawals.
