Profit calculator
What does a good month actually make?

Where campaigns stop making money
You're $7,600 ahead for the month — but check each campaign's ROAS against 2.94x break-even before scaling anything.
This, but automatic and daily
The calculator works on averages; your business works on specifics — per SKU, per channel, per campaign, updated every day. Data Doodle does this math continuously across your connected stores and ad accounts.
