Commission Calculator

See what a marketplace commission really takes, compare two platforms, and find the price needed to keep your margin.

Selling price

Cost of the goods sold

Materials, labour and packaging for this item.

Marketplace commission %

The headline rate the platform quotes.

Payment processing %

Fixed charge per transaction

The flat part of the processing charge. It hurts small sales far more than large ones.

Listing or renewal fee per sale

A listing fee, a renewal, a promoted listing charge or a subscription amortised per sale.

Shipping and other costs you pay

Anything else the sale costs you rather than the buyer.

Target margin %

Optional. A MARGIN, which is a share of the selling price. Used to find the price that holds it after the fees.
