The future value of a monthly deposit A=125.30 at annual interest i=0.015 per annum for n=35 years compounded monthly is given by FV=A((1+i/12)^(12*n)-1)/(i/12) =125.30(1+0.015/12)^(12*35)/(0.015/12) =$69156.05
The annuity formula is given by Payment = r(PV)/(1-(1+r)^(-n)) where r=interest rate per period = 0.015/12 PV= $69156.05 n=20*12=240 so Payment = (0.015/12)<span>69156.05/(1-(1+0.015/12)^(-240)) = $333.71 per month.</span>
