Sports Card Grading ROI Calculator

The problem with grading decisions

Grading a sports card costs $25-$150+ depending on service level and turnaround. Most collectors guess whether grading is worth it based on gut feeling. The math is simple in theory — will the graded value exceed the raw value plus grading fees? — but the data to make that calculation is scattered across price guides, eBay comps, and PSA population reports.

How the grade ladder works

• • See the market value at every grade: Raw, PSA 7, 8, 9, and 10
• • Grading fees (PSA, BGS, SGC) automatically deducted from profit
• • Cross-grade analysis: "If I crack this PSA 8 and resubmit, what's my upside at a 10?"
• • Grade probability estimates based on population data
• • Clear verdict: GRADE, HOLD RAW, or CRACK & RESUBMIT

PSA vs BGS vs SGC — which grading company?

Different grading companies command different premiums. A PSA 10 typically sells for more than a BGS 9.5 or SGC 10 for most modern cards, but BGS Black Labels can exceed PSA 10 values. Slabfy's grade ladder compares all three so you can choose the grading company that maximizes your ROI. Read more in our PSA vs BGS vs SGC comparison guide.

Should I grade my card?

The answer depends on the card, the expected grade, and the current market. Slabfy runs the numbers so you don't have to. Just scan or search your card and the grade ladder tells you the move — with real data, not guesses. Learn more about grading ROI and when it's worth it.
