Free ROAS Calculator: Revenue, Profit and Break-Even
ROAS tells you how much revenue advertising generated for each dollar spent. It does not tell you whether the campaign was profitable until you include product cost and other variable costs.
How this free tool works
Calculate ROAS, contribution profit, ACOS and break-even ROAS from your ad spend, revenue and variable costs. Free with no signup. The result is designed to be transparent: you can see the inputs, the formula and the assumptions instead of receiving a black-box score.
ROAS = attributed revenue ÷ ad spend. Contribution profit = revenue − variable costs − ad spend. Break-even ROAS = 1 ÷ contribution margin.
Best for
- Paid-media teams comparing channel performance
- Operators who want revenue and profit in one view
- Anyone who needs an actual break-even threshold, not a vanity benchmark
Frequently asked questions
What is a good ROAS?+
There is no universal good ROAS. The correct threshold depends on your contribution margin, fees, returns and other variable costs.
Can a campaign have positive ROAS and still lose money?+
Yes. ROAS uses revenue, while profit also subtracts product cost, shipping, fees, refunds and advertising spend.
What is ACOS?+
ACOS is ad spend divided by attributed revenue. It is the inverse view of ROAS: ACOS = 1 ÷ ROAS.
