ROAS (Return on Ad Spend) Calculator
Enter your ad spend, the revenue it generated, and your gross margin to get the campaign's ROAS along with the break-even ROAS your margin actually requires to be profitable.
Compare revenue to ad spend, and see the break-even ROAS your margin actually requires.
A ROAS above your break-even ratio means the campaign is profitable after cost of goods; below it, you're paying to acquire revenue at a loss.
ROAS and break-even ROAS
ROAS = Revenue / Ad spend Break-even ROAS = 1 / Gross margin
ROAS alone doesn't tell you if a campaign is profitable — a 3x ROAS loses money at a 20% margin (needs 5x to break even) but is very profitable at a 60% margin (needs only 1.67x). Comparing ROAS to your margin-adjusted break-even point is what tells you if you're actually making money.
How to use
- Enter total ad spend and the revenue directly attributable to those ads.
- Enter your gross margin — revenue minus cost of goods sold, as a percentage of revenue.
- Compare your ROAS to the break-even ROAS: above it means the campaign is profitable after cost of goods, below it means you're losing money per dollar of ad spend.
Example
Input: $2,000 ad spend, $8,000 revenue, 50% gross margin
Output: ROAS = 4x, break-even ROAS = 2x, profit ≈ $2,000

FAQ & notes
Why is a high ROAS not always good enough?
ROAS measures revenue against spend, not profit against spend. A low-margin product needs a much higher ROAS to be profitable than a high-margin one — always check ROAS against your break-even point, not against a generic benchmark.
How is this different from ROI?
ROI typically nets out all costs (including cost of goods) to measure profit directly, while ROAS is a simpler revenue-to-spend ratio media buyers use for quick campaign comparisons. This calculator bridges the two by layering your margin on top of ROAS.
