Understanding your calculation
Method, example and limitations
How the calculation works
Future value projects a current sum using FV = PV(1 + r)^n. If contributions are included, their amounts and timing also affect the final balance.
Example to check
$1,000 growing at 10% annually for two years becomes $1,210 without additional deposits. That is $210 of growth, rather than $200 from simple interest.
Before using the result
Constant-return projections do not represent market volatility. Review fees, taxes, inflation and whether contributions happen at the start or end of a period.
