The future value of an annuity is given by:
(where, R is the monthly contribution amount; i, the rate of interest and n is the number of periods).
Here, the payments and interest compounding occur monthly, so the interest rate per period is 0.065/12=0.005416667
and the number of compounding periods is 35*12 = 420.
Substituting the information into the formula for future value of an annuity gives:
Thus, the required monthly contribution is `R 625` .
