In order to calculate the compound amount, we can use the following formula for compound interest:

Where A is the final amount after t years, P is the principal (initial amount), r is the rate and n is how many times the interest is compounded in a year.
So, for P = 32350, r = 0.06, t = 4 and n = 1, we have:

Therefore the amount after 4 years is $40,841.13.
