What is CTR Calculator?
CTR Calculator helps you compare clicks with impressions to find a click-through rate.
The main result is click-through rate. The formula, example and assumptions below explain how to interpret it.

Understanding the CTR result
The main output is click-through rate, expressed in %. It applies to the inputs and operation you selected.
Displayed results use a readable number of decimal places. When checking a result by hand, keep extra precision until the last step. To compare scenarios, change one input at a time and keep the others fixed.
CTR Calculator: assumptions and common mistakes
A useful estimate starts with the right inputs. Check the following assumptions and limits before applying the result to your situation.
- Match numerators and denominators from the same reporting period. Creator RPM is revenue per thousand views, while advertiser CPM measures spending.
