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:
Ⅲ
N = 360 (30 years x 12 months)
Ⅲ
APR = 8
Ⅲ
PV = 100,000
Ⅲ
FV = 0
