To solve this problem using a financial calculator, we need to break it down into two parts:
- The withdrawals.
- The deposits.
Let's establish the parameters for each part separately.
Withdrawals
- Present Value (PV): This is the current account balance, which is $11,568.00.
- Future Value (FV): This will be determined later.
- Payment (PMT): This is the amount withdrawn every other year, which is -$5,577.00 (negative because it's an outflow).
- Number of periods (N): The withdrawals occur every other year for 6 withdrawals, so N = 6.
- Interest rate (i/y): Since the account pays 6% annually, for every other year, we'll divide by 2, so i/y = 3.00%.
Using the values for withdrawals:
- N = 6 (total withdrawals)
- i/y = 3.00 (6%/2)
- PMT = -5,577.00
- PV = 11,568.00
- We need to calculate the FV.
Deposits
- Payment (PMT): This is the amount deposited every other year which is +$11,568.00 (positive because it's an inflow).
- Number of periods (N): The deposits occur every other year for 6 deposits, so N = 6.
- Interest rate (i/y): Again 3.00% (6%/2).
- Future Value (FV): This will also be calculated after determining the value after the withdrawals.
- PV: The PV of new deposits starts from 2 years from today, so it needs to be adjusted.
Using the values for deposits:
- N = 6 (total deposits)
- i/y = 3.00 (6%/2)
- PMT = 11,568.00
Combining Both
- After calculating the future value of the account after the withdrawals, we will then calculate the future value of the deposits from that adjusted time frame.
- Finally, we sum the future values from both parts to determine the total in the account after 24 years.
Steps on the Financial Calculator
For Withdrawals:
- Enter N = 6
- Enter i/y = 3.00%
- Enter PV = 11,568.00
- Enter PMT = -5,577.00
- Compute FV (this yields the future value of the withdrawals).
For Deposits:
- You will now need to adjust the PV based on the future value found in the first calculation and account for the timing of the cash flows.
- Set N = 6
- Set i/y = 3.00%
- Enter PMT = 11,568.00
- Compute FV (this calculates the future value of the deposits).
Finally, sum the FV of withdrawals and FV of deposits to get the total amount in the account after 24 years.
Key Notes to Remember
- Make sure to adjust for the timing of the withdrawals and deposits.
- Carefully input the signs (positive for deposits and negative for withdrawals) as they affect the FV computation.
