Slab-or-sell ROI
Should you grade this card,
or sell it raw?
Quick answer: grading a card is worth it when its expected graded value, minus the grading fee and shipping, beats what it sells for raw today. The math hinges on the PSA 10 premium and the odds of a 10. Plug in the four numbers below and the calculator returns your expected profit, the break-even price, and a grade-or-sell verdict.
Verdict

Expected profit versus selling raw: $92. A graded copy needs to clear $73 just to beat selling it raw today.

Estimate only. Assumes a worthwhile submission lands a 9 or 10; cards likely to grade lower should usually be sold raw. ZeroPop runs this math automatically on every scan, using the grade it predicts for your specific card.
How the math works
Every grading decision comes down to one comparison: the expected value of the slabbed card versus the cash in hand from selling it raw. The formula is simple:
+ (chance of 9 × PSA 9 price)
− grading fee − shipping − raw value
If that number is positive, grading beats selling raw. The break-even price is the raw value plus the all-in submission cost: the slab has to clear that just to match doing nothing. The further a card's PSA 10 price sits above its raw and PSA 9 price, the more grading pays, which is why pulling the PSA 10 premium and the odds of a 10 matters more than the raw price itself.
Worked example: a $40 card
Say a raw card sells for $40, lists at $80 as a PSA 9 and $250 as a PSA 10, and your all-in submission cost is $33. With a coin-flip 50% shot at a 10, the expected graded value is about $165, or $132 after costs. That is roughly $92 more than selling raw, so the verdict is grade it. Drop the PSA 10 price to $90 and the same card flips to sell raw, because the premium no longer covers the fee. Small changes in the 10 price decide it.
Frequently asked questions
How do I know if a card is worth grading?+
A card is worth grading when its expected graded value, weighted by the odds of each grade, minus the all-in submission cost, beats what it sells for raw today. The biggest swing factor is the PSA 10 premium: cards with a large gap between their PSA 9 and PSA 10 price and a realistic shot at a 10 are the ones worth submitting.
What is the break-even on grading a card?+
Break-even is the raw value plus the all-in submission cost (grading fee plus shipping and supplies). The graded card has to sell for at least that amount just to match selling it raw. Anything above break-even is profit; anything below means you lost money grading it.
Is it worth grading a $40 card?+
It depends on the PSA 10 price, not the raw price. A $40 card that sells for $300 as a PSA 10 with a fair chance of a 10 is usually worth grading; a $40 card that sells for $60 graded is not, because the premium does not cover the fee. Enter the numbers above to see the break-even.
How accurate is this ROI estimate?+
The math is exact; the inputs are estimates. The two numbers that move the result most are the PSA 10 price and the odds of a 10. ZeroPop predicts the grade from a scan of your specific card, so the in-app version fills in the odds for you instead of you guessing.
Skip the guessing on the odds.
ZeroPop scans your card, predicts the PSA, BGS, and CGC grade, and runs this exact ROI math automatically, so you get the verdict without estimating the odds of a 10 yourself.
