About this ctr calculator
Calculate clicks as a percentage of impressions. Results above 100% include a warning to check the counting definitions.
How this tool works
CTR (%) = clicks / impressions × 100. For 100 clicks and 1000 impressions, the result is 10%. The percentage updates from the two input fields without a submit button.
- Set these visible inputs: Clicks = 100; Impressions = 1000
- Read the automatically updated result and compare it with the example.
Worked example
Scenario: Set these visible inputs: Clicks = 100; Impressions = 1000 Read the automatically updated result and compare it with the example.

Limits and verification
Clicks must be finite and nonnegative; impressions must be finite and positive. A result above 100% is retained with a warning because definitions can count multiple clicks per impression. Compare the same date range and click definition. Results use floating-point arithmetic. Ordinary values show up to two decimal places; small and large values use scientific notation with seven significant digits.
Examples demonstrate an expected workflow; they do not prove every input or every branch of an external specification. Check important results with an independent source before using them for money, security, compliance, safety, or irreversible file changes.
Browser processing boundary
Tool input is processed by code running in the browser and is not intentionally sent to a CZOA processing API. The page can still request ordinary site assets, analytics, or advertising when those services are enabled. Browser extensions and managed-device software remain outside this tool's control.
