a. | ||
We would calculate the amount at retirement using future value of annuity formula | ||
Future value of annuity | Annuity*[((1+r)^n)-1]/r | |
r represents interest rate and n represents no of payments | ||
Monthly interest rate | 0.92% | 10.99%/12 |
No of payments | 300 | 25*12 |
Calculation of future value of annuity | ||
Future value of annuity | 300*[((1+0.0092)^300)-1]/0.0092 | |
Future value of annuity | 300*1573.394 | |
Future value of annuity | $472,018.21 | |
b. | ||
After tax amount received at maturity | 472018.21*(1-0.30) | |
After tax amount received at maturity | $330,412.74 | |
c. | ||
Using the present value of annuity formula the monthly payment can be calculated | ||
Present value of annuity | Annuity*[1-((1+r)^-n)]/r | |
Monthly interest rate | 0.67% | 8%/12 |
No of payments | 240 | 20*12 |
Annuity | 330412.74/[1-(1.0067^-240)]/0.0067 | |
Annuity | 330412.74/119.5543 | |
Annuity | $2,763.70 | |
Thus, monthly amount received would be $2,763.70. | ||
