The average amount that you've been charged for a click on your ad. Average cost-per-click (avg. CPC) is calculated by dividing the total cost of your clicks by the total number of clicks.

• Your average CPC is based on your actual cost-per-click (actual CPC), which is the actual amount you're charged for a click on your ad. Note that your average CPC might be different than your maximum cost-per-click (max. CPC), which is the highest amount that you're willing to pay for a click.
• Here's an example of how to calculate your average CPC. Let's say your ad gets two clicks, one costing $0.20 and one costing $0.40, for a total cost is $0.60. You'd divide $0.60 (your total cost) by 2 (your total number of clicks) to get an average CPC of $0.30.
• You can find your average CPC amounts in the "Avg. CPC" column in Campaigns.
