Finance buttons

Finance buttons enable you to find an unknown variable value based

on a group of known variable values.

For example, to calculate the monthly payment for a 30-year home

loan of $100,000 with an annual interest rate of 8%, you would enter

the following variables:

■

Payments/year = 12

■

N = 360 (30 years x 12 months)

■

APR = 8

■

PV = 100,000

■

FV = 0

Using these variables, the answer would be -733.76 per month.

To solve this exmaple:

1. Enter a value and then tap the corresponding variable button.

Repeat this process until you’ve entered the following four

variables:

■

N = 360 (30 years x 12 months)

■

APR = 8

■

PV = 100,000

■

FV = 0

2. Enter 12 and tap the P/Yr button to enter the number of payments

per year.

3. Tap Edit.

4. Tap the Pmt line and erase all values on the line including zero.

5. Tap Solve.

6. Tap Done.

You can use a similar process to solve other financial equations by

entering four of the variables to find the value of the fifth variable.
