How much is my graphing calculators worth?

Offers depend on the exact model, condition, and current market demand, so we quote every item live rather than posting prices that go stale. The best way to find out what yours is worth is a free, no-obligation evaluation.

A graphing calculator is one of the few school supplies that holds its value — a working TI-84 sells for real money years after the course ends. Demand peaks every semester as new students need them, so yours is worth cash whether finals ended last week or three years ago. We test the screen and keypad in store and pay on the spot: an easy win for students, and a smart cleanout for parents whose graduates left one in a drawer.

Any condition considered

Working calculators with screens intact.
