Calculating amortizations

Amortization calculations determine the amounts applied

towards the principal and interest in a payment, or series

of payments. They also use TVM variables.

To calculate amortizations:

1. Start the Finance app.

2. Specify the number of payments per year (P/YR).

3. Specify whether payments are made at the beginning

or end of periods.

4. Enter values for I%YR, PV, PMT, and FV.

5. Enter the number of payments per amortization

period in the Group Size field. By default, the

group size is 12 to reflect annual amortization.

6. Tap . The calculator displays an amortization

table. For each amortization period, the table shows

the amounts applied to interest and principal, as well

as the remaining balance of the loan.

Example:

Amortization for a

home mortgage

Using the data from the previous example of a home

mortgage with balloon payment (see page 289),

calculate how much has been applied to the principal,

how much has been paid in interest, and the balance

remaining after the first 10 years (that is, after 12 × 10 =

12 0 p aym e n t s ) .

1. M a k e yo u r d a t a

match that shown in

the figure to the right.
