Breakeven ROAS tells you the minimum performance required to cover advertising. Target ROAS should sit above that floor so the business preserves contribution after acquisition.
Start with contribution margin
Calculate the contribution generated by an order before advertising. That is the pool available to fund acquisition and profit.
Subtract desired profit
If an order contributes $40 and you want to keep $12 after ads, allowable ad cost is $28.
Convert allowable CPA into ROAS
If the platform tracks $80 of revenue and allowable ad cost is $28, target ROAS is about 2.86x.
Keep revenue definitions consistent
Do not mix gross revenue, after-return revenue and margin percentages from different definitions. Consistency matters more than false precision.
Use a range
Attribution and product mix create noise. A calculated target such as 2.86x is often better treated as an operating range around 2.8-3.0x.
Calculate your own break-even point
Use your real product costs, fees, returns and conversion rate instead of relying on generic targets.

How do I calculate target ROAS?
Estimate allowable ad cost after preserving desired profit, then divide tracked revenue by allowable ad cost.
Is target ROAS the same as breakeven ROAS?
No. Breakeven is the economic floor; target ROAS is normally higher.
Should target ROAS stay fixed?
No. Recalculate it when costs, AOV, return rate or discounting changes.
