$\displaystyle A = A_0\left(1 + \frac{r}{n}\right)^{nt}$

$\displaystyle A$ = investment value at any time t in years

$\displaystyle A_0$ = initial investment

$\displaystyle r$ = annual interest rate as a decimal

$\displaystyle n$ = number of compounding periods per year

$\displaystyle t$ = number of years
