Card Grading ROI Calculator
Grading a card is a bet: you pay a fee and wait weeks hoping the graded card sells for more than the raw copy. This card grading ROI calculator does the math for you, comparing the expected value of grading against selling raw so you only submit cards that actually pay off.
Grading ROI Calculator
Pull the price inputs from recent eBay sold listings for your exact card.
How to Use It
- Look up your exact card on eBay and filter by Sold Items.
- Enter the raw price, the PSA 9 price, and the PSA 10 price from those solds.
- Enter your all-in fee per card (tier price plus shipping, spread across the submission).
- Set your honest chance of a 10. When in doubt, assume the 9.
- Read the verdict. A positive edge of 20% or more is a clear grade.

Frequently Asked Questions
How does the grading ROI calculator work?
It compares the expected value of your graded card against selling it raw. Enter the raw price, the grading fee, the PSA 9 and PSA 10 sold prices, and your honest odds of a 10. The tool weighs the outcomes and subtracts fees to give a verdict.
What gem rate should I use?
Be conservative. Start from the PSA population report ratio for your exact card, then lower it for any flaw you can see. Most collectors overestimate their gem odds by about one grade.
When is grading not worth it?
When the expected graded value does not clear the raw price plus all fees, or when a card has visible flaws. Junk wax base cards and anything below mint almost never profit from grading.
