Trigonometry buttons
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 example:
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
