It is a free Shopify profit margin calculator that turns your price, COGS, shipping, fees and ad spend into net profit, margin, markup, break-even price and break-even ROAS.

Net profit starts with your selling price, then subtracts product cost, shipping you pay, discounts, payment fees, refunds and ad cost per order.

Margin is profit as a percentage of the selling price. Markup is profit as a percentage of your cost. The calculator shows both side by side.

Break-even price is the lowest price at which you make no loss. Break-even ROAS is the return on ad spend you need to cover all costs.
