Multi-card Deal Calculator
Add cards with different market prices and buying percentages, total the offer and optionally calculate resale profit.
Different percentages in one deal
Each card can have its own market price and buying percentage. Enter card 1 at market 100 and 80% to obtain 80, then card 2 at market 200 and 90% to obtain 180. The total offer is 260 against a reference market total of 300.
Add only the resale prices you know
Sale price is optional for each card. With resale prices of 100 and 200 in the two-card example, the modelled gross profit is 40. If only one card has a sale price, the profit total applies only to cards with entered sale prices; it is not a profit prediction for the whole unpriced bundle.
Use individual entries for different cards
Add a row for each card or slab so each reference amount and percentage remains visible. You can remove an entry, export the deal to CSV or print it. Inputs are stored on the browser device, not shared between visitors.
Keep negotiations simple
This is a deal arithmetic tool with no automatic pricing feed, grading assessment or fees. Agree your reference values separately. Market value may differ from what you will actually achieve when reselling.
Common questions
Does the example apply one percentage to everything?
No. It totals the individual buying prices, so an 80% card and a 90% card remain distinct.
Can I leave all sale prices blank?
Yes. You will get the buy total and reference market total without a profit claim.
