TI-Nspire CX Used Value Calculator
Use this calculator to estimate the fair market value of a used TI-Nspire CX or TI-Nspire CX II graphing calculator. The value is influenced by its original price, age, physical condition, and included accessories.
Enter the approximate price of the calculator when new (e.g., $150 – $180).

Understanding the Value of a Used TI-Nspire CX Graphing Calculator
The TI-Nspire CX series, including the CX and CX II models, are powerful graphing calculators widely used by students and professionals for advanced mathematics, science, and engineering. When buying or selling a used unit, several factors determine its fair market value.
Key Factors Influencing Used Calculator Price:
- Original Retail Price: Newer models or those with advanced features (like the CX II CAS) generally hold a higher base value. Our calculator uses a typical new price as a starting point.
- Age of the Calculator: Like most electronics, graphing calculators depreciate over time. Newer models (1-2 years old) will command a higher price than older ones (5+ years old), even if in similar condition. Our calculator applies a depreciation rate based on the age you provide.
- Physical and Functional Condition: This is a major determinant.
- Excellent: Looks and functions like new, no visible scratches or dents.
- Good: Minor cosmetic wear (light scratches), fully functional.
- Fair: Noticeable scratches, dents, or screen imperfections, but still fully functional.
- Poor: Significant cosmetic damage, potential minor functional issues (e.g., sticky buttons, dim screen), but still usable.
- Included Accessories: Having the original charger, USB data cable, a protective case, and the user manual adds value. Buyers often prefer a complete package.
- Market Demand: While harder to quantify in a simple calculator, demand can fluctuate. During back-to-school seasons, demand (and thus prices) might be slightly higher.
How the Calculator Works:
Our calculator takes your inputs for the typical new price, age, condition, and included accessories to provide an estimated used value. It applies a base depreciation for age, then adjusts this value based on the selected condition, and finally adds a small bonus for each included accessory.
Realistic Examples:
- Example 1: Nearly New, Excellent Condition
New Price: $170, Age: 1 year, Condition: Excellent, Accessories: Charger, USB Cable, Case, Manual
Estimated Value: ~$140 – $155 (Slight depreciation, high condition bonus, accessory bonuses) - Example 2: Average Use, Good Condition
New Price: $160, Age: 3 years, Condition: Good, Accessories: Charger, USB Cable
Estimated Value: ~$95 – $110 (Moderate depreciation, standard condition, basic accessories) - Example 3: Older, Fair Condition
New Price: $150, Age: 5 years, Condition: Fair, Accessories: Charger Only
Estimated Value: ~$55 – $70 (Significant depreciation, lower condition, minimal accessories)
Remember, this calculator provides an estimate. Actual selling prices can vary based on your local market, urgency of sale, and negotiation.
