How this calculation works

Future balance = compounded starting savings + compounded monthly contributions.

The projected balance is divided by (1 + inflation)^years to express purchasing power in today’s dollars. The target comparison uses the same today-dollar basis.

A worked example

With $10,000 saved and $100 per month for 10 years at 0% return and 0% inflation, the projected balance is $22,000.

Assumptions and limitations

This is an accumulation projection, not a retirement income or withdrawal sustainability model. No taxes, fees, pensions, employer matching, or variable returns. Contributions stay fixed in nominal dollars.
