Final answer:
To make future withdrawals of $24,000 a year for 5 years plus an additional $40,000 in year 15, you would need to deposit approximately $72,665.40 today.
Step-by-step explanation:
To calculate how much must be deposited today to make these future withdrawals possible, we need to use the concept of present value. The formula for present value is:
Present Value = Future Value / (1 + Interest rate)Number of years
In this scenario, the future value is the sum of the annual withdrawals for 5 years, plus the additional amount in year 15. So, the future value is $24,000 x 5 + $40,000 = $160,000. The interest rate is 8% and the number of years is 11. Plugging these values into the formula, we get:
Present Value = $160,000 / (1 + 0.08)11 = $72,665.40
Therefore, the amount that needs to be deposited today to make these future withdrawals possible is approximately $72,665.40.
