Revenue and ROAS don’t tell you if you made money.
Most 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.
These tools give you that number for one order. Built for Shopify brands doing between 50k and 1m per month, Vibel gives it to you for every order, every SKU and every channel, every morning.
