We combine real-time market prices, PSA gem rates, and grading costs to calculate the expected value of grading any Pokemon card. The answer to “should I grade this?” — backed by data, not guesswork.
We pull from the same sources professional graders and dealers use, then do the math so you don't have to.
Current raw and graded sale prices from PriceCharting, updated weekly. We track PSA 7 through PSA 10, plus BGS, CGC, and SGC sale prices across 8,800+ cards.
Gem rates and grade distributions from actual PSA submissions. We know the probability of getting a 10, a 9, an 8 — and use every grade outcome in our expected value calculation.
21 tiers across PSA, BGS, CGC, SGC, and TAG with up-to-date 2026 pricing. Switch between companies and see how the math changes instantly.
Expected Value (EV) is a probability-weighted calculation that accounts for every possible grade outcome. Unlike simple profit calculators that only show you the PSA 10 scenario, our EV formula considers the realistic probability of getting each grade — from PSA 10 down to Authentic — and weights each outcome by its market value.
For grades without market price data, we use the raw card price as a conservative floor — because you can always crack the slab and sell it ungraded.
This gives you the true expected return on your grading investment, not just the best-case scenario. Your real outcome over many grades should converge toward the EV.
A positive expected value doesn't always mean you should grade. Our verdicts factor in the full picture.
A card with 5 graded copies and 80% gem rate means nothing — that's 4 out of 5. We flag low-population cards and require 100+ submissions before giving a confident "Yes."
Your PSA 10 is only worth $500 if someone actually buys it. We check sales volume to make sure there's a real market, not just one lucky auction.
Our EV formula accounts for every possible grade, not just the 10. Getting a PSA 8 on a card you paid $200 for can mean losing money — we factor that in.
Cards from sets released in the last 6 months have unstable pricing. Today's $100 card could be $40 by the time your slab comes back from PSA.
