Based on the calculation below, the amount that can be withdrawn each month for 10 years is a. $769.27.
Calculation of monthly withdraw
First, we calculate the future value (FV) of the amount after 20 years using the formula for calculating the Future Value (FV) of an Ordinary Annuity as follows:
FV = A * (((1 + r)^n – 1) / r) ................................. (1)
Where,
FV = Future value of the amount after 20 years =?
A = Monthly deposit = $235.15
r = Monthly interest rate = 3.2% / 12 = 0.00266666666666667
n = number of months = 20 * 12 = 240
Substituting the values into equation (1), we have:
FV = $235.15 * (((1 + 0.00266666666666667)^240 – 1) / 0.00266666666666667) = $78,910.41
The amount planned to be withdrawn on monthly basis can be calculated using the formula for calculating the present value (PV) of an ordinary annuity as follows:
P = PV / ((1 - (1 / (1 + r))^n) / r) …………………………………. (2)
Where;
P = Monthly withdrawal or payment = ?
PV = Present value = FV calculated above = $78,910.41
r = Monthly interest rate = 3.2% / 12 = 0.00266666666666667
n = number of months = 10 * 12 = 120
Substitute the values into equation (2), we have:
P = $78,910.41PV / ((1 - (1 / (1 + 0.00266666666666667))^120) / 0.00266666666666667) = $769.27
Therefore, the amount that can be withdrawn each month for 10 years is $769.27.
