Break-even ROAS table
Break-even ROAS and ACoS for each margin before ads (profit per order before ads ÷ price). Below the break-even ROAS every ad-driven order loses money.
| Margin before ads | Break-even ROAS | Break-even ACoS |
|---|---|---|
| 10% | 10.00 | 10% |
| 15% | 6.67 | 15% |
| 20% | 5.00 | 20% |
| 25% | 4.00 | 25% |
| 30% | 3.33 | 30% |
| 35% | 2.86 | 35% |
| 40% | 2.50 | 40% |
| 50% | 2.00 | 50% |
| 60% | 1.67 | 60% |
Worked example
Price $24.99, landed cost $6.52, 15% commission, $5 fulfillment, 5% returns. Profit before ads is $8.94, 35.76% of the price, so break-even ROAS is 2.80 (ACoS 35.76%). To keep a 10% margin ROAS needs to reach 3.88. At a 10% conversion rate, clicks above $0.89 lose money. At the current ROAS of 4, each ad-driven order makes $2.69.
| Profit per order before ads | $8.94 |
|---|---|
| Break-even ROAS | 2.80 |
| Break-even ACoS | 35.76% |
| Target ROAS | 3.88 |
| Target ACoS | 25.76% |
| Most ad spend per order | $8.94 |
| Highest bid per click | $0.89 |
| Profit per ad order now | $2.69 |
How it works
- Profit per order before ads = price × share not returned × (1 − commission − payment rate) − payment fixed fee × share not returned − fulfillment − return rate × handling per return − landed cost × (share not returned + return rate × cannot be resold).
- Break-even ACoS = profit before ads ÷ price; break-even ROAS = 1 ÷ break-even ACoS = price ÷ profit before ads.
- Target ACoS = break-even ACoS − target margin; target ROAS = 1 ÷ target ACoS.
- Most ad spend per order = profit before ads; highest bid per click = most ad spend per order × conversion rate.
- Profit per ad-driven order now = profit before ads − price ÷ current ROAS.

Questions
How do ROAS and ACoS relate?
ROAS = ad-attributed sales ÷ ad spend; ACoS = ad spend ÷ ad-attributed sales. One is the inverse of the other: a ROAS of 4 is an ACoS of 25%. Amazon reports ACoS; Meta, Google and TikTok mostly report ROAS.
What does break-even ROAS mean?
The ROAS at which an ad-driven order neither makes nor loses money. If profit before ads is 25% of the price, break-even ACoS is 25% and break-even ROAS is 4. Below 4, every ad-driven order loses money.
Should I stop ads that are below break-even?
Not always. Launches that build ranking, ads that bring organic sales and products with repeat buyers can carry losing ads for a while, as long as you know how much each order loses and for how long. This calculator looks at the ad-driven order on its own.
Why count returns?
Ad dashboards usually count ROAS on ordered sales and don't take returns back out. Apparel returns are high, so leaving them out makes the break-even line look lower than it is, and ads that seem profitable lose money.
How do I use the highest bid per click?
The most an order can spend on ads times the conversion rate is what one click is worth. If an order can spend $8 and 10% of clicks buy, an average cost per click above $0.80 loses money. Bid below it to keep a margin.
How is TACoS different from ACoS?
ACoS counts only ad-attributed sales; TACoS is ad spend ÷ all sales, organic included. The more organic orders, the lower the TACoS. This calculator uses ACoS.
