Revenue is a vanity number. Plug in your total costs and ad spend to see your real contribution margin, the ROAS you need to break even, and whether the store makes money after ads.
Open calculatorPromo impact
Discount calculator
A 20% off promo is not 20% off your profit - it is far more. See the real margin hit and how many extra units you have to sell just to break even on the deal.

Break-even ROAS calculator
Enter your supplier cost, shipping and fees to see the exact ROAS you must beat to profit per order. Shows your max CPA and profit at your target ROAS.
Open calculatorMost ecommerce dashboards report revenue and blended ROAS. Neither tells you if you are making money. Contribution margin - what is left after COGS, shipping, fees and ad spend - is the number that actually matters. These calculators put that number in front of you in seconds, for free.
