Calculator Details

The calculator has 11 inputs; 6 are required:

  • Your current age
  • ROI for retirement savings
  • Age at which you want to retire
  • Retirement income lasts until what age
  • Desired retirement income
  • ROI during retirement

There are 5 optional inputs. Any or all can be left at 0.

  • Annual contribution increase
  • Current retirement savings
  • Income from government
  • Other annual income
  • Annual inflation rate

Click the [Help] button for more details about each input.



If “For retirement income, withdraw only interest” is checked, you will not be able to enter a value for “Retirement income lasts until age” because withdrawing only interest means the principal remains untouched. Theoretically, the income will last indefinitely. An exception occurs if you enter a value for “Annual inflation rate”; then only the first withdrawal will equal the interest earned for the year. Subsequent withdrawals will exceed the interest to offset inflation.

This retirement savings calculator is designed to help you plan for a secure future.
