Answer:
$46,922.09
Explanation:
we must first determine the amount of money your father will receive in 10 years adjusted to inflation:
future value = $60,000 x (1 + 4%)¹⁰ = $88,814.66
I used an excel spreadsheet to calculate the other 24 payments. Since the retirement plan will continue to earn 10% per year, I calculated the present value of the distributions (when your father turns 60) = $1,227,639.71.
This means that your father's retirement account must have $1,227,639.71 by the time he turns 60 years old.
Your father currently has $185,000 which will gain interest and its future value = $185,000 x (1 + 10%)¹⁰ = $479,842.36
He will be $1,227,639.71 - $479,842.36 = $747,797.35 short.
In order to determine the annual contribution, we have the use the future value of an annuity formula:
- future value = $747,797.35
- FV annuity factor, 10%, 10 periods = 15.937
annual contribution = $747,797.35 / 15.937 = $46,922.09
