Seller profit tools

Calculate your real selling costs before you list.

Seller Cost Guide helps online sellers estimate marketplace fees, product costs, net profit, profit margin and suggested pricing before selling on platforms like Etsy, eBay, Shopify and other ecommerce channels.

Start with a calculator

Use these tools to test pricing scenarios, estimate net profit and understand which costs may be reducing your margin.

Built for online sellers, not generic spreadsheets

Estimate real profit

Look beyond revenue and understand what may be left after product cost, shipping, packaging, fees and advertising.

Test pricing scenarios

Change prices, costs and target margins to see how small adjustments can affect net profit.

Compare before you list

Use platform-specific and generic calculators to decide whether a product is worth selling.
