TI-83 vs TI-84 Cost Formula and Mathematical Explanation

To objectively compare the ti 83 vs ti 84 graphing calculator, we look beyond the shelf price. We calculate the “Total Cost of Ownership” (TCO) over the student’s academic career (typically 4 years of high school + 4 years of college).

The mathematical formula for the Total Cost (C) over time (t) in years is derived as follows:

For TI-83 Plus:
C83(t) = P83 + (Cbat × Nbat × t)

For TI-84 Plus CE:
C84(t) = P84

Variable Definitions

Variable Meaning Unit Typical Range
P83 Price of TI-83 Plus USD ($) $80 – $100
P84 Price of TI-84 Plus CE USD ($) $110 – $150
