Endowment Mortgage Example One:
Stewart and Linda took out a £220,000 endowment-type mortgage loan twelve years ago with an interest rate of 7.5% compounded annually. They have been putting an extra £300 on to their monthly payments to try and re-pay the principal, and have made a £10,000 lump sum payment five years ago. They plan to make another £10,000 payment in about three years.
Solution Using Loan Calculator:
Access the Loan Calculator from the Home page, and enter the data as follows:
- . Enter the £220,000 in the Amount borrowed field.
- . Enter the Loan Date as 12 years ago today.
- . Leave the Renewal Date as the default for now, since we are first calculating for the interest only payments.
- . Enter an Interest Rate of 7.5%.
- . Click the drop down menu under the Compounding field and choose Annual.
- . Also leave the Amortization at the default for now.
- . Click the drop down menu under Payment Type and choose the Interest Only option.
- . If necessary change the Frequency of Payments to the Monthly option.
- . Click on the Calculate button next to Payment.
The result should be £1,329.88.
- . Now we must add the payments they make towards the principal. Change the Payment to £1,629.88 to show the extra payment of £300 each month
- . Set the Number of Irregular Payments to two (2): one for the payment they have already made and the second for the planned future payment.
- . Click Set
- . Set the first Date field to five years ago today, with the Amount as £10,000
- . For the second irregular payment, set the Date to three years from today, for the Amount of £10,000.
- . Click Calculate beside the Amortization
The answer should be roughly 21 years.
- . Click on the Schedule button at the bottom of the screen to view the payment schedule.
- . Identify the Balance that remains at today’s date.
The balance of the mortgage should be £137,068.62
