TI-84 Plus CE Purchase Formula and Explanation

To determine exactly how much you need to save and when you can afford to buy TI 84 Plus CE graphing calculator units, we use a straightforward budgeting formula. This accounts for the base retail price and your local tax jurisdiction.

The Formula

Total Cost (C) = Price (P) + (Price (P) × Tax Rate (T))

Amount Needed (N) = Total Cost (C) – Current Savings (S)

Weeks to Save (W) = Amount Needed (N) / Weekly Contribution (Cw)

Variable	Meaning	Unit	Typical Range
Price (P)	Retail Price before tax	Currency ($, €, £)	$100.00 – $150.00
Tax Rate (T)	Percentage added by government	Percentage (%)	0% – 25%
Savings (S)	Money currently available	Currency	$0.00 – Total Cost
Contribution (Cw)	Money saved per week	Currency / Week	$5.00 – $50.00
