Break-Even ROAS Calculator – Find Your Minimum ROAS
Break-even ROAS Calculator — 100% free, unlimited, no sign-up cost.
Break-even ROAS is 1 divided by your profit margin; if your margin is 40%, break-even ROAS is 2.5, meaning each dollar of ad spend must return $2.50 in revenue to cover costs.
Enter the profit margin on what you sell and the calculator returns the ROAS you need just to cover your ad spend. It ignores other overheads, so treat it as a floor for campaign decisions, not a profit target.

The Break-even ROAS formula
Break-even ROAS = 1 ÷ Profit Margin
Profit Margin is expressed as a decimal (25% = 0.25). This is the minimum ROAS where ad spend stops being a loss.
Example
Your product has a 25% profit margin.
1 ÷ 0.25 = 4.0x break-even ROAS
Worked example: 40% margin
A product sells for $100 and leaves $40 profit before ad costs, a 40% margin.
- Break-even ROAS = 1 ÷ 0.40 = 2.5x.
- Spending $1,000 needs $2,500 of attributed revenue just to recover the ad cost.
- A campaign reporting 2.0x is losing money at this margin; one at 3.5x is profitable before other overheads.
What to do next: Check the margin includes product cost, shipping and payment fees, then compare against each campaign's ROAS over the same period. Platform-reported ROAS and your own accounting may differ.
Why it's free
Platform dashboards report ROAS without telling you whether it is good. The answer depends on margin: a 60% margin business breaks even at 1.7x, a 20% margin business needs 5x. Knowing the floor tells you which campaigns to pause or scale.

What is the formula behind the Break-even ROAS Calculator?
Break-even ROAS = 1 ÷ Profit Margin. Profit Margin is expressed as a decimal (25% = 0.25). This is the minimum ROAS where ad spend stops being a loss.
What is a good ROAS?
It depends on your margin. Anything above your break-even ROAS makes money on the ad spend; below it you lose money, even if the revenue number looks large.
Should I use gross margin or profit margin?
Use the margin that remains after product costs, shipping and fees but before ad spend. That tells you how much of each sale is available to pay for ads.
Is break-even ROAS the same as target ROAS?
No. Break-even is the floor where ad spend is exactly recovered. A target ROAS sits above it so the business also earns a profit after ad cost.
