You want to retire in 38 years and have $100,000 currently saved in an account earning 9.5% interest. How much must you deposit into that account each month to be able to retire for 25 years and withdraw $500,000 per year if you are able to earn 5% during retirement?
Annuity Withdrawl Required (P)= | 500000 |
interest rate (i)= | 5% |
time for Annuity withdrawl (n)= | 25 |
Present Value of ordinary annuity formula = (Annuity *(1-(1/(1+i)^n))/i) |
|
=500000*(1-(1/(1+5%)^25))/5% |
|
=7046972.283 | |
So fund needed at Retirement is | $7046972.28 |
Current deposit (present value) = | 100000 |
interest rate (i)= 9.5% number of years (n) = 38 future value = present value *(1+i)^n =100000*(1+9.5%)^38 =3145839.264 |
|
Ballance Future value required to be saved =7046972.28- 3145839.26 | 3901133.02 |
Time in years (n) = | 38 |
interest rate (i)= | 9.5% |
Amount required to save each year Formula = Future value*i/(((1+i)^n)-1) |
|
3901133.02*9.5%/(((1+9.5%)^38)-1) |
|
12167.6689 | |
So annual Contribution needed is | $12167.67 |
