Why We Built
These Calculators
Most ecommerce founders run their businesses on gut feeling and vanity metrics. They know their revenue, they track their ROAS, and they watch their order counts. But when you ask them about profit, real actual profit after all costs, the answers get vague.
These calculators exist to give you a reality check. They strip away the complexity and show you the numbers that actually matter: Are you profitable? What's killing your margins? How much ROAS do you actually need to break even?
Use them to understand your business better. Then use MerchantFlow to track it all automatically, without spreadsheets, without guessing, and without hoping your math is right.
