PSA Grading Calculator — Should You Grade Your Pokemon Card?
This free PSA grading EV (Expected Value) calculator helps Pokemon card collectors decide whether grading a card with PSA is worth it. Search for any Pokemon card to see real PSA population data, gem rates, graded market prices, and calculate your expected return on investment from grading.
How the EV Calculation Works
EV = (PSA 10 rate x PSA 10 price) + (PSA 9 rate x PSA 9 price) + (PSA 8 rate x PSA 8 price) + (PSA 7 rate x PSA 7 price) + (below-7 rate x raw price) - raw card cost - grading fees - shipping. Cards grading below PSA 7 are valued at the raw card price because you still own the card. PSA grading fees are probability-weighted per grade outcome because PSA only upcharges when the graded value exceeds the tier cap.

What is a Gem Rate?
The gem rate is the percentage of submitted cards that receive a PSA 10 (Gem Mint) grade. A low gem rate (under 5%) means the card is very difficult to grade a 10, while a high gem rate (over 20%) means most submissions receive the top grade. Gem rate directly impacts your expected value from grading.

PSA Grading Tiers & Fees
| Tier | Fee | Turnaround | Max Declared Value |
|---|---|---|---|
| Bulk | $19 | ~90 days | $499 |
| Economy | $50 | ~45 days | $999 |
| Express | $150 | ~10 days | $2,499 |
| Super Express | $300 | ~5 days | $4,999 |
| Premium | $1000 | ~1 day | $24,999 |
If your card's graded value exceeds the tier's declared value cap, PSA will upcharge to the appropriate tier. This calculator accounts for upcharges automatically.
What is a Gem Rate?
The gem rate is the percentage of submitted cards that receive a PSA 10 (Gem Mint) grade. It's calculated from PSA's public population data: if 10,000 copies of a card have been graded and 500 received a PSA 10, the gem rate is 5%.
Gem rate directly impacts your expected value. A card with a 20% gem rate and a $500 PSA 10 premium is a much better grading candidate than a card with a 2% gem rate and the same premium — even though the upside looks identical, you're 10x more likely to achieve it.
Frequently Asked Questions
What is grading EV?
EV (Expected Value) is the probability-weighted return on a grading submission. Unlike just looking at the PSA 10 price, EV accounts for the realistic odds of each grade outcome and factors in all costs. A positive EV means grading is profitable on average across many submissions.
What if my card grades below PSA 7?
Cards grading below PSA 7 are valued at the raw card price in our calculation — you don't lose the card, you just don't profit from grading it. The only cost is the grading fee and shipping you already paid.
How accurate is this calculator?
The calculator uses real PSA population data and live market prices. However, individual results vary — your card's actual condition, centering, and surface quality all affect the grade you receive. Use the condition adjustment feature to fine-tune your estimate.
