Should you grade it?
Grading can multiply a card's value, or quietly lose you money on fees. Put in the raw value, the top-grade comp, and your odds, and see the expected return before you ship.
“Value if top grade” is the comp for the grade you realistically expect (often PSA 10 / PSA 9). Be conservative on the chance, surface flaws are easy to miss.
Rule of thumb: grade when the top-grade comp is at least ~3–5× your raw + fees, and you're confident in the card's condition. Estimates only, not financial advice.
When grading is worth it
Grading costs a per-card fee plus shipping and insurance, and takes weeks. It pays off when a high grade is both likely and worth a large multiple of the raw price. A common rule of thumb: grade when the top-grade comp is at least 3–5× your all-in cost (raw value + fees) and the card looks clean, sharp corners, no surface scratches, good centering.

Questions, answered
How does the grading ROI calculator work?+
Enter the card's raw value, the comp price at the top grade you're targeting (e.g. PSA 10 / CGC 10), your grading cost, and your estimated odds of hitting that grade. The tool weighs the expected payoff against your all-in cost and tells you whether grading is likely to beat just selling the card raw.
Where do the prices come from?+
You supply the raw and graded comps yourself, so the math reflects your own research. For raw values you can use Foilio's free search, which shows honest Cardmarket EUR reference prices via free catalog APIs, never sold-listing scrapes or paywalled data. Graded comps you'll want to pull from recent like-for-like sales of the same card and grade.
Is the calculator free, and do I need an account?+
Yes, it's completely free with no sign-up. It runs entirely in your browser, your inputs stay on your device, and nothing is sent to a server.
Which games and graders does it cover?+
The calculator is grader-agnostic, it works for PSA, CGC, BGS or any service as long as you enter that service's fee and a comp for the grade you're after. The same math applies to Pokémon, Magic, Yu-Gi-Oh! or any collectible card.
