Present Value Calculator
Discount a future lump sum into today’s dollars using an explicit rate, time horizon, and compounding frequency. The calculator uses present value = future value ÷ (1 + rate ÷ compounds)^(compounds × years). It returns more than one result so you can check the main answer against a useful secondary measure. A higher discount rate or longer wait reduces present value. The selected discount rate is an assumption, not a guaranteed investment return or inflation forecast.

How the calculation works
Use consistent units and retain full precision until the final display step.
Worked example
Reproduce the displayed scenario, then change one assumption at a time.
Assumptions behind the result
- • Inputs use the units shown beside each control.
- • The displayed formula is applied without hidden market or demographic data.
- • Rounding occurs only for display; calculations keep full numeric precision.
- • A higher discount rate or longer wait reduces present value.
- • The selected discount rate is an assumption, not a guaranteed investment return or inflation forecast.
Mistakes that change the answer
- • Mixing percentages with decimals or mixing incompatible units.
- • Relying on a rounded intermediate value instead of the full result.
- • Changing several assumptions at once instead of testing future amount separately.
