ROAS Formula
Return on Ad Spend (ROAS) measures the revenue generated for every dollar spent on advertising. A ROAS of 4x means you earn $4 for every $1 spent on ads. The same result is sometimes written as a percentage — 4x and 400% describe the identical outcome.
Example: If you spend $1,000 on ads and generate $4,000 in revenue, your ROAS is 4x (or 400%).

How to Improve Your ROAS
What is a ROAS calculator?
A ROAS calculator divides campaign revenue by the ad spend behind it and returns a multiple.
- $6,000 of revenue on $2,000 of spend is a ROAS of 3x
- Break-even ROAS moves with product margin
- One team can scale at 2x where another cannot
- Inside AdBid it is read beside attribution, payback and LTV
ROAS is a signal, not the whole answer
The ROAS formula, and what each input has to mean
ROAS = revenue attributed to the campaign ÷ ad spend behind it.
- $6,000 revenue ÷ $2,000 spend = 3x
- Use attributed revenue, not total store revenue
- Use the same window for revenue and for spend
- Break-even ROAS = 1 ÷ gross margin
A ROAS calculator is a signal, not the whole answer
A ROAS number is useful when it is connected to the business model.
- Compare revenue against ad spend.
- Review profit and margin context.
- Use attribution to confirm which campaign produced the value.
Read return through margin and payback
The same ROAS can mean different budget decisions.
- Add gross-margin context before calling a campaign profitable.
- Compare short attribution windows with cohort payback.
- Use LTV assumptions carefully when cohorts are still maturing.
