Break-Even ROAS: The Minimum Return You Need to Profit
Practical guide to calculating your break-even ROAS: basic formula, adjusting for cash-on-delivery, ready-made table, and difference between break-even ROAS and target ROAS.
SymplysisAI editorial team7 min readWhat is break-even ROAS and why does it determine your profit?
Before you understand break-even ROAS, remember that ROAS itself is simply return on ad spend: how many dollars of sales come back per dollar you spend on ads. If you spent $1000 on a campaign and got $3000 in sales, ROAS equals 3.
Break-even ROAS is the threshold number: the return where you neither profit nor lose, because all profit before ads goes to cover ad costs. Any return above it means net profit; any below means loss with every order. You can't judge a campaign as winning or failing until you know your product's break-even threshold.
The key insight many sellers miss: break-even ROAS isn't a universal number to borrow from videos or other sellers—it comes directly from your product's profit margin. High-margin products tolerate lower ROAS and stay profitable; thin-margin products need high ROAS just to survive. So the right question isn't 'what's a good ROAS?' but 'what's my break-even ROAS?'
How do you calculate break-even ROAS step by step?
Break-even ROAS calculation needs no complex tools—just five clear steps from sale price to threshold number. The principle is simple: know how much stays from each sale before ads, then convert that margin to a return threshold.
- 1Set the product's actual sale price as the customer pays it.
- 2Sum all variable costs except ads: product, shipping, packaging, collection or payment fees.
- 3Subtract these costs from sale price to get profit before ads (margin in currency).
- 4Divide profit before ads by sale price to get profit margin percentage.
- 5Divide 1 by this margin percentage; the result is your break-even ROAS.
How does cash-on-delivery change break-even ROAS calculation?
The basic formula assumes every order gets paid. That's true for digital products and prepaid card orders, but unrealistic for cash-on-delivery where not all orders reach delivery. Some get refused at the door or are never picked up, and you absorb the outbound and return shipping cost without getting paid.
So measure your sales by what actually paid you, not registered orders, and distribute return-shipping losses across delivered orders. This raises your real break-even ROAS above the simple formula number—a major reason campaigns look profitable on paper but lose in reality.
Return shipping cost spread per delivered order = return shipping cost × (non-delivery rate ÷ delivery rate). Subtract this from your profit before ads before calculating the margin to get a break-even closer to reality.
Quick table: profit margin vs. break-even ROAS
Instead of recalculating each time, read your break-even directly from your profit margin. Notice how break-even threshold drops sharply as margin rises—exactly why raising margin before scaling budget matters.
| Profit margin before ads | Break-even ROAS |
|---|---|
| 20% | 5.00 |
| 25% | 4.00 |
| 30% | 3.33 |
| 40% | 2.50 |
| 50% | 2.00 |
| 60% | 1.67 |
| 70% | 1.43 |
Difference between break-even ROAS and target ROAS
Reaching break-even means you didn't lose, but you also didn't profit and haven't covered fixed costs like subscriptions and salaries. So don't make break-even your goal—make it your floor. Target ROAS is the return that leaves you net profit after ads, always higher than break-even.
To calculate target ROAS, subtract your desired net profit percentage from your margin, then divide 1 by the result. If your margin is 40% and you want 15% net profit from sales after ads, target ROAS = 1 ÷ (0.40 − 0.15) = 1 ÷ 0.25 = 4.
- Break-even ROAS: covers ads only, zero profit.
- Target ROAS: covers ads and leaves net profit margin for you and fixed costs.
- The bigger the gap between actual return and break-even, the more profit per ad dollar.
Common mistakes that make break-even ROAS calculation misleading
The number is only useful if its inputs are complete. Most hidden losses come from real costs missed from the equation or measuring sales wrong.
From number to decision: how to use break-even ROAS daily
Once you know your break-even threshold, ROAS shifts from a display number to a decision tool. Make break-even your pause line: any campaign staying below it after sufficient testing stops; any consistently exceeding your target ROAS deserves budget increases.
The smarter path isn't just chasing higher ROAS but lowering the break-even threshold itself, which happens by raising margin, boosting average order value through upsells and bundles, or lifting conversion rate so you get more sales from the same spend. A clearer landing page and stronger ad copy mean higher ROAS without budget increases—an easier break-even to hit.

Questions and answers
What's the difference between ROAS and break-even ROAS?
ROAS is your actual return from a campaign: sales divided by ad spend. Break-even ROAS is the reference number you must exceed to profit, derived from your profit margin. You compare the two: if your actual return exceeds break-even threshold, you're winning; if it's below, you're losing.
What's a good break-even ROAS?
No single number works for everyone because it depends entirely on your profit margin. A 50% margin gives a threshold of 2.0, a 25% margin gives a threshold of 4.0. Lower thresholds are easier to hit, so instead of chasing a perfect number, work to raise your margin so your threshold drops.
How does cash-on-delivery affect break-even ROAS?
It raises it. Because some orders don't deliver and you absorb outbound and return shipping without getting paid. Spread return-shipping losses across delivered orders and measure sales based on what you actually collected, not what was registered, to get a break-even that's higher and truer than the simple formula.
Should I target break-even ROAS or higher?
Target higher. Break-even means zero profit and doesn't yet cover fixed costs. Calculate target ROAS by subtracting your required net profit percentage from your margin, then dividing 1 by the result. Make break-even your floor, not your goal.
How do I lower the break-even ROAS required?
Three levers: raise margin through better supplier terms or smarter pricing, boost average order value via bundles and upsells, and raise conversion rate with a stronger landing page and ad copy. All three increase what you earn per ad dollar, lowering the threshold you need to hit.
