Used TI 84 Calculator Formula
To determine the profitability of reselling a used TI 84 calculator, we utilize the standard Break-Even Point (BEP) formula. This helps resellers understand how many units they must sell to cover their costs.

Variables
- Fixed Costs (F): Total costs that do not change with the number of used TI 84 calculators sold (e.g., eBay store subscription, bulk cleaning supplies).
- Price (P): The selling price of a single used TI 84 calculator.
- Variable Costs (V): Costs directly tied to one unit (e.g., shipping a specific calculator, cost of batteries, acquisition cost per unit).
- Quantity (Q): The number of used TI 84 calculators that must be sold to reach profitability.

What is a Used TI 84 Calculator Assessment?
A used TI 84 calculator assessment is a financial calculation used by students, electronics recyclers, and resellers. The Texas Instruments TI-84 Plus is a staple in high school and college math classes, creating a robust secondary market. Understanding the break-even point ensures that you are not selling the hardware for less than it costs to acquire and refurbish it.
By inputting your specific costs, this calculator helps you determine the optimal listing price for a used TI 84 calculator or the volume required to justify a bulk purchase of school surplus equipment.
Whether you are a student looking to flip your old device or a business managing inventory, accurate calculation of margins is essential to avoiding losses in the competitive electronics market.
How to Calculate Used TI 84 Calculator Break-Even (Example)
Let’s say you buy a lot of broken calculators to fix. Here is how you find your break-even number:
- Identify Fixed Costs: You spend $100 on soldering tools and listing software (F = $100).
- Identify Variable Costs: It costs you $30 to buy one broken unit and $5 for parts (V = $35).
- Set Price: You plan to sell a refurbished used TI 84 calculator for $85 (P = $85).
- Apply Formula: Q = $100 / ($85 – $35) = $100 / $50 = 2.
- Result: You need to sell exactly 2 calculators to break even.
Frequently Asked Questions (FAQ)
Does this calculator work for the TI-84 Plus CE?
Yes, the financial logic applies to any model, including the used TI 84 Plus CE, Silver Edition, or the original TI-83, as long as you input the correct costs.
What is a good profit margin for a used TI 84 calculator?
Resellers typically aim for a 20-30% net margin. You can adjust the “Price” variable in the calculator to see how a higher price affects the quantity needed to break even.
Why is my result negative?
If your variable cost (V) is higher than your selling price (P), you are losing money on every sale. The calculator will flag this as an impossible break-even scenario.
Can I use this for bulk school purchases?
Absolutely. Enter the total cost of the bulk lot as your Fixed Cost (if paying a lump sum) to determine how many individual units you need to sell to recover your investment.
