Break-even ROAS tells you the minimum efficiency needed to cover advertising from contribution margin. Target ROAS is the performance level you actually aim for. Confusing the two can lead to campaigns that technically break even but do not create enough profit for the business.
Break-even ROAS is your economic floor
Your floor comes from unit economics. If contribution margin is 40%, the simplified break-even ROAS is 2.5x. Use the Break-Even ROAS Calculator when your costs include shipping, fees, discounts or returns.
Target ROAS should sit above the floor
A target needs to leave room for profit and fixed operating expenses. The exact buffer depends on the business. A company prioritizing growth may accept a narrower buffer than one prioritizing cash generation.
Do not set targets from platform benchmarks alone
Two stores can have the same 3x campaign ROAS and completely different profit outcomes because their margins, AOV and return rates differ. Read break-even ROAS by profit margin before comparing your account with someone else's.
Use actual ROAS to measure the gap
Once a target is set, compare it with current performance using the ROAS Calculator. A campaign below target is not automatically bad; it may still be above break-even and worth optimizing rather than pausing.
Recalculate when economics change
Price changes, discounting, shipping costs and product mix can all move the break-even point. Targets should be reviewed when those inputs move materially, not treated as permanent account settings.
Turn the guide into your own numbers
Use your real costs and campaign data instead of relying on a generic benchmark.
Calculate break-even ROASFrequently asked questions
Is target ROAS the same as break-even ROAS?
No. Break-even ROAS is the minimum economic floor; target ROAS should normally include room for desired profit and operating costs.
Can target ROAS be too high?
Yes. A very restrictive target can sacrifice volume even when additional sales above break-even would still be valuable.
How often should I recalculate target ROAS?
Recalculate when margins, pricing, return rates, shipping costs or product mix change materially.
