For your target margin
Your campaign
Profitable: 19.8% margin after ads.
How it's calculated
Profit before ads is your order value minus product cost, shipping, other costs and fees. That is the most you can spend on ads to win one order and still break even, your maximum cost per acquisition.
Break-even ROAS = order value ÷ profit before ads. Target ROAS does the same after first setting aside your target profit margin. Break-even ACoS is the inverse, shown as a percentage.
Campaign check turns your ad revenue into orders, then subtracts ad spend from the profit those orders made before ads.
Questions sellers ask
What is break-even ROAS?
Break-even ROAS is the return on ad spend at which an ad campaign makes zero profit. It equals your order value divided by what each order leaves you after product, shipping and fee costs. Below it, ads lose money; above it, they make money.
How do I calculate break-even ROAS?
Subtract product cost, shipping and platform or payment fees from your average order value to get your profit before ads. Then divide the order value by that number. For example, a $60 order that leaves $30 before ads has a break-even ROAS of 2.0x.
What is a good ROAS?
There is no universal good ROAS, because it depends on your margins. A product with high margins can be profitable at 1.5x, while a low-margin product may need 4x or more. Use your break-even ROAS as the minimum and your target ROAS as the goal.
What is the difference between ROAS and ACoS?
ROAS is revenue divided by ad spend, while ACoS (used on Amazon) is ad spend divided by revenue, shown as a percentage. They are inverses: a 4x ROAS equals a 25% ACoS. Your break-even ACoS equals your profit margin before ads.
