How It Works
How to Calculate Cost Per Click
Formula
CPC = Total Ad Spend / Total Clicks
CPC tells you the price you pay for each visitor acquired through paid advertising. Lower CPC means your budget stretches further, but CPC alone does not determine campaign success. A low CPC with poor conversion rates can still produce a negative return. Always evaluate CPC alongside conversion rate and cost per acquisition.
Worked Example
An ad campaign spent $2,000 and generated 800 clicks.
- 01CPC = $2,000 / 800 = $2.50
- 02Clicks Per Dollar = 800 / $2,000 = 0.40
- 03Each click costs $2.50 on average.
