Click-Through Rate (CTR) Calculator

Quickly translate clicks and impressions into a CTR percentage and keep your marketing performance transparent.

Input values

Raw values must be non-negative integers; impressions must be greater than zero to produce a meaningful CTR.

How to use this calculator

All calculations are based on the standard CTR formula: the number of clicks divided by impressions, multiplied by 100 to produce a percentage. Use this calculator to benchmark ad creatives, call-to-action copy, or placement performance.

Step-by-step

  1. Enter the total clicks your campaign or link received during the selected period.
  2. Enter the total impressions (how many times the creative was shown).
  3. Hit Calculate to see the CTR percent and watch the narrative explain what the rate means for your reach.

Glossary of variables

  • Clicks: Every time a user interacts with your link or ad.
  • Impressions: The total opportunities the creative had to be seen.
  • CTR: The percent of impressions that turned into clicks.

Example

An ad with 500 clicks and 10,000 impressions yields a CTR of 5.00%. That means 5 out of every 100 impressions converted into clicks.
