How this calculation works

CPM alone measures delivery cost. Add CTR and post-click conversion rate to estimate clicks, conversions, and CPA.

Clicks = impressions × CTR; conversions = clicks × conversion rate; CPA = spend ÷ conversions.

Example calculation

100,000 impressions at 1% CTR and 5% conversion rate produce 1,000 clicks and 50 conversions.

Change either input in the calculator to model a different campaign scenario.

Use the result correctly

  • Enter CTR and conversion rate as percentages.
  • Keep click and conversion definitions consistent.
  • A lower CPM is not automatically better if traffic converts poorly.
