How it works
The formula
ROAS is the revenue each unit of ad spend brought back: 6,000 revenue on 1,500 spend is 4, or 400%.
ROAS = revenue ÷ ad spend
Break-even ROAS
Enter your gross margin and the tool gives the ROAS you need just to cover the ad spend, which is one divided by the margin. At a 40% margin that is 2.5. Profit is revenue times margin minus spend.
