AdMetricFlow provides free calculators for common paid media metrics such as CPM, CPC, CTR, CPA, ROAS and ROI.
The site is built for marketers, founders, ecommerce operators and agencies who need quick, understandable checks before making campaign decisions.
The tools use standard advertising formulas and user-entered campaign figures. They are designed for planning, checking and reporting support, not for replacing platform dashboards or financial accounts.
Useful AdMetricFlow pages should explain what each metric means, when it matters, what can distort it, and how it fits into campaign profitability.
If a formula, explanation, or example looks wrong, please use the contact page so it can be checked.
