About Seller Profit Toolkit

Seller Profit Toolkit helps independent sellers make pricing decisions with clearer numbers. It brings costs, marketplace fees, shipping, and profit goals into a single workspace.

Built around the sale

Our calculators focus on the economics of one order. You can edit every modeled fee, compare scenarios, and export the results without creating an account.

International by design

The toolkit is written in English and supports sellers in the United States, United Kingdom, Canada, Australia, selected European countries, and other markets through custom fee settings.

Transparent by default

We publish our formulas, assumptions, and fee sources. This is an independent project, not an official marketplace service. We do not claim that a target price guarantees sales or business income.
