Grade it or sell it raw?

Enter what the card sells for raw and graded, and how likely each grade is. You'll see the expected profit after grading fees, shipping and selling fees, plus the chance you lose money.

Odds of 7 or lower fill in as whatever is left. Not sure? Population reports show how often a card gets each grade, and it's safer to lean low.

How the math works

For each grade, the calculator takes the graded sale price minus selling fees, then subtracts the grading cost and what you'd have kept by selling raw. Weighting each grade by your odds gives the expected profit.

net(price) = price × (1 − fee%) − fixed fee
profit(grade) = net(graded price) − grading cost − net(raw price)
expected profit = Σ odds × profit(grade)

GRADE IT means the expected profit beats your target return. MARGINAL means a likely profit that's thin for the wait and risk. SELL RAW means grading is expected to lose money.
