For compounding interests, we use the equation F = P (1+i) ^n where F is the future amount of the principal amount, P, in n years. Take note that the interest to be used should be the effective interest rate. In this case, it is already the effective interest rate.

F = P (1+i) ^n

F = $4000 (1+.055) ^4

F = $4955.2986
