Card Grading Calculator
Grading can multiply a card's value — or lock in a loss. This free tool weighs the odds and the costs so you can see, in numbers, whether to grade your card or sell it raw.

Simplified model: it assumes the card grades either a 10 (at your odds) or a 9 (the rest of the time). Real submissions can come back lower, so treat the result as a favourable-case guide and shade your odds down if condition is uncertain.
How to read the result
The calculator computes your expected graded value — the value of a 10 and a 9 weighted by your odds — then subtracts the grading cost and compares it to selling raw. It also shows the break-even probability: the minimum chance of a 10 at which grading just matches selling raw. If your realistic odds sit comfortably above that number, grading is favourable; if they're below it, sell raw.
Before you rely on it
- Be brutal about condition. Centring, corners, edges and surface decide 9 vs 10. If any are off, drop your odds. See is my card worth grading.
- Use your all-in cost. Grading fees plus shipping and insurance — the full breakdown is in how much does it cost to get cards graded.
- Pick the right grader. Which slab sells best affects your 9 and 10 values — compare PSA vs CGC vs BGS.
