Grading ROI Calculator
Don't grade blind. Plug in what your card sells for raw, what a 9 and a 10 sell for, your grading tier, and see if the math actually works.
Enter raw value and expected sale prices.
How this works
Expected graded value is a weighted average: P(10)×Sale10 + P(9)×Sale9 + (1 − P9 − P10)×SubSale. We subtract sale fees, grading fees, and shipping. Then we compare to your raw-sale net.
If you don't fill in a sub-9 sale price, we assume it goes back to raw value (you sell it raw on return).
FAQ
How do I estimate P(9) and P(10)? +
Look at how many gem mints the card has on the pop report vs total population. For modern cards with sharp corners and centered, 10–25% gem rate is realistic. Vintage is way lower — often under 5% for a 10.
Are these fees current for 2026? +
PSA, BGS, and SGC update tier pricing periodically. The defaults are typical brackets — always override with the fee you'll actually pay. Bulk submissions often unlock cheaper tiers.
What about insurance and return shipping? +
We bundle insurance into the "shipping both ways" number. A safe rule for $500+ cards is ~$15 each way through Registered Mail.
What's the rule of thumb? +
If your card raw is under ~$30 and a 10 doesn't fetch at least 3× a 9, grading usually isn't worth it. Vintage, autos, and key rookies are where grading prints money.
