How our calculators work
Runs in your browser, 100% private
No data you enter is ever transmitted to our servers or stored in any database. All calculations happen locally on your own device.
No fabricated benchmarks
We do not show arbitrary claims like "a good ROAS is 4x". Real performance thresholds depend strictly on your own margins and cost structure.
Useful even without JavaScript
Formulas, worked examples and in-depth explanations are static HTML. You can read and verify every equation even with JavaScript disabled.
About our marketing calculators
Are these tools really free?
Yes, all our calculators are completely free. You do not need to create an account, leave an email address, or enter payment details.
Is my financial data stored anywhere?
No. Everything runs strictly inside your web browser. When you refresh or close the tab, all your entered values are cleared.
How can I share my calculation with my team?
Click the "Copy link" button inside any calculator panel. This creates a URL with your inputs encoded in query parameters, ready to send to teammates.
The maths is done. Are the numbers right?
ROAS and CPA are only as accurate as your tracking. Missing or duplicated conversions break every calculation above. Let an independent audit check your measurement.
