Your uncle is 75 years old and he has $3,065,359 saved for her retirement. He expects to live for another 30 years and he receives a 9% rate (APR) from Retirement-Bank. How much should he withdraw at the end of each of the next 30 years, so that he ends up with zero in the account (he uses all of his savings by the end of those 30 years)?

Final answer:

An uncle with $3,065,359 saved for retirement needs to calculate a fixed annual withdrawal at a 9% annual rate over 30 years to deplete his savings. The annuity formula P = (r × PV) / [1 - (1 + r)^(-n)] is used to determine the fixed payments. Substituting the given values into the formula, we calculate the precise amount to withdraw each year.

Step-by-step explanation:

The student's question involves determining how much an uncle, who is 75 years old with $3,065,359 saved for retirement, should withdraw annually at a 9% annual rate over the next 30 years to deplete his savings entirely. To solve this, we use the annuity formula, which calculates the fixed payments over a certain period at a specified interest rate. The formula is: P = (r × PV) / [1 - (1 + r)^(-n)], where P is the payment, r is the annual interest rate, PV is the present value, and n is the number of payments.

Calculating the Annual Withdrawal

To find out the exact withdrawal amount, we need to plug the values into the formula:

PV (Present Value of Retirement Savings) = $3,065,359
r (Annual Interest Rate as a decimal) = 0.09
n (Number of Years) = 30

The formula for the yearly withdrawal then becomes:
P = (0.09 × 3,065,359) / [1 - (1 + 0.09)^(-30)], calculating this gives us the fixed annual amount the uncle needs to withdraw to use all his savings by the end of the 30 years.
