Other formulas:

 

Simple Interest

I = PV * i * N

PV - principal or present value
i - interest rate per period
N - number of periods

 

Annuity

FV = PMT * [ ( ( 1 + i )N - 1 ) / i ]

FV = future value (maturity value)
PMT = payment per period
i = interest rate in percent per period
N = number of periods

 

Compounded Interest

i = FV - PV

PV = present value
FV = future value (maturity value)
i = interest rate in percent per period
