What it measures
Google Ads Target ROAS is the return-on-ad-spend goal for Smart Bidding, set above your break-even ROAS to leave the profit margin you want.
Formula
Break-even ROAS = 1 ÷ Margin · Suggested Target ROAS = Break-even × (1 + Profit goal)
Worked example
At a 40% margin, break-even ROAS is 250%, and with a 50% profit goal the suggested Target ROAS is 375%.
Typical benchmarks

How this calculator works
Break-even ROAS = 1 ÷ profit margin (shown as a percentage). At a 40% margin you break even at 250% ROAS. Multiply by your desired profit goal to set a target that actually nets profit.
Frequently asked questions
How do I calculate break-even ROAS? +
Divide 1 by your profit margin. A 25% margin needs a 400% (4×) ROAS just to break even before any profit.
What Target ROAS should I set? +
Above break-even by the margin you want to keep. Set it too high and Google limits volume; too low and you lose money.
Why does a higher Target ROAS reduce my volume? +
A higher target tells Google to bid only on traffic likely to hit that return, which shrinks the eligible audience and lowers impressions and conversions.
Does Target ROAS need conversion values? +
Yes. The strategy optimizes toward revenue per dollar, so you must pass accurate conversion values, not just conversion counts.
How is Target ROAS different from Target CPA? +
Target CPA optimizes for a fixed cost per conversion regardless of value; Target ROAS optimizes for revenue return, favoring higher-value conversions.
