Buy offer
Enter each card’s market price: the calculator removes the fees of the platform you will resell on, your contributions and your target margin, then splits the offer card by card.
Same calculation as the app’s buyer mode: offer = market price − resale fees − contributions − target margin, never below zero, then split by largest remainder in proportion to the prices.
Indicative figures: the platform’s own statement prevails.
Nothing leaves your device: no upload, no cookie, no tracker.
Example
Three cards priced €60, €25 and €25 (€110.00), resold hand to hand, contributions at 12.4% and a 30% target margin: maximum offer €63.36.
The same calculation, on your whole stock
The app runs this calculation for every card and every sale, with your real cost, your usual shipping and your estimated contributions.
