Breakeven ROAS: the formula, a worked example and what “good” means
Breakeven ROAS is the return on ad spend at which an order neither makes nor loses money. The formula is: breakeven ROAS = 1 ÷ contribution margin before ads, where contribution margin is what is left from each rupee of revenue after product cost, shipping, payment fees and returns. If 40% of revenue is left, breakeven ROAS is 1 ÷ 0.40 = 2.5x.
Key takeaways
- There is no universal “good ROAS”: it depends on your margin.
- Use net revenue after cancellations and RTO, not the platform's gross revenue.
- Breakeven ROAS covers each order; you need a higher ROAS to also cover salaries and rent.
- Track POAS (profit on ad spend) once your numbers are reliable.
The formula
Breakeven ROAS = 1 ÷ (contribution margin before ads, as a share of revenue)
Contribution margin before ads is revenue minus product cost (COGS), forward and reverse shipping, packaging, payment gateway and COD fees, and the cost of returns and RTO.
Worked example: an Indian D2C order
| Item | Per order |
|---|---|
| Average order value | ₹1,500 |
| Product cost | ₹500 |
| Shipping | ₹80 |
| Packaging + gateway | ₹40 |
| Contribution before ads | ₹880 (58.7%) |
| Breakeven ROAS | 1,500 ÷ 880 = 1.70x |
Now add a 15% RTO rate. Returned orders bring no revenue but still cost forward and reverse shipping, so the real breakeven moves above 2x. That is why ROAS that looks healthy in Ads Manager can still lose money. Try your own numbers in the breakeven ROAS calculator.
Unit breakeven vs business breakeven
Unit breakeven ROAS only covers the cost of each order. To cover fixed costs such as team, rent, tools and agency fees, you need the operating breakeven ROAS: (ad spend + fixed costs) ÷ (ad spend × contribution margin). At low ad budgets, fixed costs push this number much higher.
So what is a good ROAS?
A good ROAS is one comfortably above your own breakeven, with room for fixed costs and profit. For a brand with a 2.1x unit breakeven, 3x may be excellent; for a brand with thin margins, 4x may still lose money. Judge ROAS against your margin, never against another brand's screenshot. To see where margin leaks, use the CM1/CM2/CM3 calculator.
How we handle this at UpscaleEra
Breakeven ROAS is the first number in our CAC Ceiling Method™. It gives you the floor. The ceiling, the most you can pay per customer and still make the margin you want, comes next, after RTO, overheads and repeat purchases. Profit Scale budgets rise only while you stay under that ceiling.
Frequently asked questions
What is the breakeven ROAS formula?
Breakeven ROAS = 1 ÷ contribution margin before ads (as a decimal). With a 40% margin, breakeven ROAS is 2.5x.
Is 2x ROAS good?
Only if your contribution margin before ads is above 50%. Below that, 2x ROAS loses money on every order.
Should I use Meta's reported ROAS?
Use it as a signal, but calculate decisions on net revenue after cancellations, RTO and returns, which is usually lower.
What is POAS?
Profit on ad spend: contribution profit divided by ad spend. A POAS above 1 means ads are adding profit, not just revenue.
