After you have perfonxied a time-value-of-money calculation, you can

amortize the results, that is, calculate the amormt of principal and the

amount of interest that you pay over a period.

The starting value for the amortization calculations, that is the point from

which the payment and interest details is calculated, is the initial value

(stored in the PV field) in the Time Value of Money input form. To

amortize payments from the previous example, perform the following:

1. Enter details for the time-value-of-money calculation, and find the

monthly payment value as in the previous example.

Press AMOR. The Amortize input form is

displayed.

3. In the Payments field, ensure that the

number of payments to amortize is set to

12, and press amor. The financial solver

amortizes the payments and displays the

results.

For the first year’s payments, the financial solver tells you:

® the principal remaining after the number of payments is made

® the interest component of the payments

® the balance of the principal after the number of payments have

been made.

Once you have amortized a batch of payments, you can set the loan

balance as the starting value for amortization. This way you can amortize

payments for each year to compare principal and interest details at

different stages of the loan.
