The concept
A retirement balance is not retirement income
A future balance model helps inspect the relationship between time, contributions and an assumed return.
It does not estimate spending needs, inflation-adjusted income, tax, fees, sequence risk or how long assets may last.
The method
How the calculation works
Current savings are compounded for the entered period. The future value of equal end-of-month contributions is calculated separately and added.
Current savings compound monthly; recurring contributions are modelled at each month-end.
Worked example
A neutral example
Starting with $50,000 and contributing $750 monthly for 25 years at an assumed 6% annual return produces an illustrative future balance.
This example explains the method. It does not recommend a financial action or predict an outcome.
