You have $39,000 in an account earning an interest rate of 4%. What are the equal beginning-of-month withdrawals you can make from this account such that it is completely depleted with the last withdrawal at the beginning of the last month in 22 years? Round to the nearest cent. [Hint: The amount in the account today is the PV of an annuity due where the withdrawals are the annuity cash flows. There will be a total of 22 x 12 withdrawals.]
Monthly rate = 4% / 12 = 0.333333%
Number of periods = 22 * 12 = 264
Presnet value = (1 + r) * Annuity * [1 - 1 / (1 + r)^n] / r
39,000 = (1 + 0.00333333) * Annuity * [1 - 1 / (1 + 0.00333333)^264] / 0.00333333
39,000 = 1.00333333 * Annuity * [1 - 0.415391] / 0.00333333
39,000 = 1.00333333 * Annuity * 175.382959
39,000 = Annuity * 175.967569
Annuity = $221.63
Monthly withdrawals will be $221.63
