Practical Examples
Here are two realistic scenarios to illustrate how the Texas Instruments TI-83 Plus Graphing Calculator price impacts your budget.
Example 1: The Single Student Purchase
A high school student needs one calculator for Algebra II. They find a new unit for $90.00 and a used unit for $60.00. Their budget is $80.00, and the local tax rate is 8%.
- New Cost: $90.00 × 1.08 = $97.20 (Over Budget)
- Used Cost: $60.00 × 1.08 = $64.80 (Under Budget)
- Result: The student saves $32.40 by choosing the used option and stays within budget.
Example 2: The Classroom Bulk Order
A math department needs to purchase 30 TI-83 Plus calculators. The vendor offers a new price of $85.00 per unit and a refurbished price of $55.00 per unit. The tax-exempt status means the tax rate is 0%.
- New Total: $85.00 × 30 = $2,550.00
- Refurbished Total: $55.00 × 30 = $1,650.00
- Savings: The school saves $900.00 by purchasing refurbished units.

Key Factors That Affect Texas Instruments TI-83 Plus Graphing Calculator Price
Several variables influence the final price you pay. Understanding these can help you find the best deal.

- Retailer Type: Educational supply stores often have higher markups than online marketplaces or general electronics retailers.
- Seasonality: Prices often spike in August and September during "Back to School" season due to high demand.
- Bundling: Some sellers include batteries, USB cables, or protective cases, which can increase the upfront price but offer better long-term value.
- Shipping Costs: Because the TI-83 Plus is relatively dense, shipping can add $10-$15 to the total cost if not offered for free.
- Model Version: While the TI-83 Plus is standard, ensure you are not comparing it against the TI-84 Plus, which generally costs more.
