Use this formula: FV=PV(1 + i)^n, where
FV=Future value
PV=present value
i=Interest rate as a decimal, e.g. 5%=5/100=.05 per period
n=number of periods.
Example: What the future value of $1,000 invested at 5% compounded annually for 10 years?
FV=1,000(1 + .05)^10
FV=1,000(1.05)^10
FV=1,000 X 1.6288946
FV=$1,628.89
