Purchase calculator

The most you can pay to keep your margin, or the price you need to resell at. Before you buy, in seconds.

A reseller's most important decision happens before the purchase: “how much can I pay for this?”. The calculator does the maths with your real fees.

Open it from the + button (the Purchase calculator row, on a phone) or from search (“calculator”, “margin”, “max price”…). It opens over the current page.

The purchase calculator

Two calculations

“I can resell it for X, how much can I pay?”

Enter the expected resale price. The result is the maximum purchase price that keeps your margin:

resale price − fees − postage − target margin = maximum purchase price

The settings

FieldDetail
Resale platformVinted, Leboncoin, eBay, Cardmarket, Whatnot or in person. By default, the platform of your last sale.
Platform fees (%)Prefilled with the rate of your last sale on that platform. Without a recent sale, enter it. In person: 0.
Postage you pay (€)Remembered from one use to the next.
Target marginAs a % of the resale price, 30% by default, remembered. It is the same definition as the margin rate in Finances.

If the calculation is impossible, Aeon explains: “At this resale price, a 30% margin is out of reach.”, or “Fees and margin take the whole price”.

Nothing is saved

The calculator creates nothing and sends no amount: you can close it safely. Only the mode, postage and target margin are remembered on your device.

The same rule is used in the wishlist to suggest a maximum price.
