You are correct. Assuming it's compounded annually, you plug in

P = 800 (the amount loaned)
r = 0.15 (15% = 15/100 = 0.15)
n = 1 (compounding 1 time per year)
t = 4 (number of years)

If you are compounding at different rates, then you change the value of n. For example, if you compound it quarterly, then you compound 4 times a year (so n = 4). If you compound monthly, then n = 12.

Use this formula A(t) = P(1+r/n)^nt
------
A(4) = 800(1+(0.15/1))^(1*4) = 800(1.15)^4 = $1399.21
