That's simple interest.

This is compounding interest:

P = C (1 + r/n) nt

where
P = future value
C = initial deposit
r = interest rate (expressed as a fraction: eg. 0.06)
n = # of times per year interest in compounded
t = number of years invested

Change "t" for each payment and then add them all up to get the sum.
