FAQ
About this calculator
What is a good ROAS?
It depends on your margins. A ROAS of 4 means $4 of revenue per $1 of ads, which is profitable only if your costs and margin leave room.
Is ROAS the same as ROI?
No. ROAS compares revenue to ad spend. ROI compares profit to cost, so it also accounts for the cost of goods and other expenses.
What counts as a conversion?
Whatever action you are paying for, such as a purchase, a booking or a form submission.
Is anything saved?
No. The math runs in your browser and nothing you enter is sent to us.
Is this tax or financial advice?
No. It is a calculator for general information. Check the numbers against your own records, and ask an accountant before you act on them.
