The compound interest equation:
P = FV          or          P = I
(1 + (R / N))N * T (1 + (R / N))N * T - 1
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
