Using the TVM Variables
FINANCE VARS Menu
To display the FINANCE VARS menu, press Œ Í ~. You can use TVM variables in TVM functions
and store values to them on the home screen.
N, I%, PV, PMT, FV
Ú, æ, PV, PMT, and FV are the five TVM variables. They represent the elements of common financial
transactions, as described in the table above. æ is an annual interest rate that is converted to a per-
period rate based on the values of P/Y and C/Y.
P/Y and C/Y
P/Y is the number of payment periods per year in a financial transaction.
C/Y is the number of compounding periods per year in the same transaction.
When you store a value to
P/Y, the value for C/Y automatically changes to the same value. To store a
unique value to
C/Y, you must store the value to C/Y after you have stored a value to P/Y.
The EasyData™ Application
The Vernier EasyData™ application by Vernier Software & Technology allows you to view and analyze
real-world data when the graphing calculator is connected to data collection devices such as Texas
Instruments CBR 2é, CBL 2é, Vernier LabProê, Vernier USB sensors, Vernier Go!éMotion, or Vernier
Motion Detector Unit. The TI-84 Plus C comes with the EasyData™ App already installed.
Note: The application is designed to work with Vernier auto-ID sensors. To use older Vernier sensors
that do not auto-ID, contact Vernier at www.vernier.com.
The EasyData™ App will automatically launch on your graphing calculator if you plug in a USB sensor
such as the CBR 2é or Vernier USB Temperature sensor.
Some new features of the EasyData™ App include:
• Added color to meters and graphs
