When an amount is entered in the input box also select what kind of amount it is by choosing "Future value (FV)" or "Interest (I)". The amount may contain max two digits after its decimal point. The amount entered may contain a comma (,) or a point (.) as a decimal point separator. Do not use the thousands separator in the amount. Correct entered amounts5123.04 5123,04 6123 Incorrect entered amounts5,123.04 5.123,04 5123.041 The compound interest equation: FV = P * (1 + (R / N)) ^{N * T}I = FV - P where: FV = Future value I = Interest amount P = Principal initial amount R = Nominal interest rate per year (as a decimal, not in percentage) T = Time period in years N = Number of compounding periods in one year |
