Value Score = (Condition Adjusted Value / Total Cost) × 10
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Listed Price | Seller’s asking price | $ | $30-$200 |
| Condition Rating | Physical and functional condition | Scale | 1-10 |

Practical Examples (Real-World Use Cases)
Example 1: TI-84 Plus Purchase
A student finds a TI-84 Plus listed for $45 with a condition rating of 8/10. The shipping cost is $8, and sales tax is 7.5%. Using our calculator for buying used graphing calculator around me:
- Listed Price: $45.00
- Condition Rating: 8/10
- Shipping Cost: $8.00
- Tax Rate: 7.5%
- Total Cost: $45 + $8 + ($45 × 0.075) = $56.38
- Condition Adjusted Value: $45 – (2 × (10 – 8)) = $41.00
- Value Score: ($41.00 / $56.38) × 10 = 7.3
