Lumpsum Calculator formula
A one-time investment is compounded at the entered annual rate for the selected number of years. The calculation assumes returns stay constant and remain invested.
How to interpret the result
The future value is a mathematical illustration, not a forecast. Compare assumptions rather than treating the largest displayed value as the most likely outcome.
Worked example
A 10,000 investment at an assumed 10% annual return for 10 years grows to about 25,937.
