Enter what a product costs you and what you sell it for, and see your gross profit, margin and markup. Or start from the margin you want and get the price to charge.

Set a markup on your cost to get the selling price, or enter cost and price to see the markup. The margin is calculated at the same time, with a markup to margin chart below.

Get your return on ad spend, and the break-even ROAS you need to stop losing money, counting product cost, shipping, payment fees and returns, not just your product margin.

POAS (profit on ad spend) tells you how much profit each dollar of advertising brings back. Above 1, your ads make money; below 1, they lose it, whatever the ROAS says.

See what a Shopify order really leaves you after product cost, shipping, payment fees, apps and advertising, and the break-even ROAS for that product.
