ShouldISlab

a card grading calculator

Know before you slab it.

Every other calculator shows you the dream — what you'd make if it gems a 10. ShouldISlab weighs that against the real odds, taken from actual PSA submission counts, not a number someone guessed. It prices every grade from recent sales, subtracts grading and selling fees, and tells you your true expected profit, your break-even grade, and when the smart move is to not grade at all.

Find your card

Search

Pick the exact version. Base, Shadowless and 1st Edition are separate cards — often 10x apart. Each grade is the median of up to 50 recent sales, and the odds come from real PSA submission counts. Cards that rarely sell can have gaps in the ladder; those are labelled as estimates.

Search a card to pull recent sales and a grade-or-skip verdict.

Your assumptions

Gem rates come from real PSA submissions — and people send in their best copies, so those odds flatter a card pulled at random. Telling us how yours actually looks shifts the odds to match.
