How to use this tool
Enter the saving-period balance, contributions, return and years until withdrawals begin.
Set the monthly retirement withdrawal and retirement horizon. Check for depletion; no safe withdrawal rate or pension entitlement is inferred.
Accumulate monthly, then grow the balance and withdraw at each month end
Worked example
$47,161.58 · projected balance at retirement
Fixed example using the settings below. Monetary examples use USD; dates and times use their stated reference values. This example stays unchanged when you edit your calculation.
Example inputs
- Starting balance: 10000
- Monthly contribution: 200
- Assumed effective annual return (%): 5
- Whole years: 10
- Monthly retirement withdrawal: 2000
- Retirement horizon (whole years): 25
Method illustration: A 120,000 balance with zero growth and 1,000 monthly withdrawals lasts 10 years.
Assumptions and limits
- Assumed rates remain constant. Values are estimates before tax and fees unless entered explicitly. No return or affordability is guaranteed.
- Calculations use full precision; displayed money is rounded to cents.
- No pension, tax, changing withdrawals or sequence risk is included. This does not establish a safe withdrawal rate.
