See what you actually make after the purchase, tax, grading, marketplace fees, and shipping. No sign-up. No spreadsheet formula.
How card profit is calculated
Net profit equals the sale price minus purchase price, inbound shipping, tax, grading, percentage-based selling fees, fixed fees, and shipping to the buyer. Break-even price accounts for percentage fees, so it is more accurate than simply adding your costs.
Does this include grading?
Yes. Enter the total grading and submission cost you want assigned to the card.
What fee rate should I use?
Use the total percentage shown by your marketplace or payment processor. Keep separate rates if both apply.
What cards can I calculate?
The same math works for sports, Pokémon, Disney, and other collectible cards.
Will my numbers be saved?
This free calculator does not save data. A free My Slab Stats account keeps costs and results organized by card.
