Card grading calculator

Is your card worth grading? Three numbers, one answer.

How it works: We compare selling raw with grading: the chance of each grade × its sold price, minus the grading fee, shipping and eBay fees. Fees are 2026 official prices.

Recent sold price, not asking price.

We guess 3× and 1.3× raw until you type your own comps.

Sets your odds of each grade. Fine-tune them in Advanced options.

FAQ

What numbers do I need?

Only three: what the card sells for raw today, and what a 10 and a 9 sell for (recent sold prices, not asking prices). Everything else has a sensible default.

Where do I find sold prices?

Type the card name and use the lookup links: eBay sold listings, 130point and the PSA and SGC population reports open in a new tab with your search filled in.

How does it pick a grading tier?

Auto picks the cheapest tier whose declared-value cap covers the card’s value at its best likely grade, which avoids upcharges. You can override it under Advanced options.

Does it save my cards?

Yes, if you click Save. Saved cards stay in this browser only (local storage). Nothing is sent to us.
