How to calculate cost per click from ad spend and clicks
Divide Total ad spend by Total clicks for the same period or campaign. With the figures below, the calculator displays:
Total ad spend: $850
Total clicks: 1,200
Cost per click (CPC): $0.7083
Implied cost per 1,000 clicks: $708.33The calculation is Total ad spend ÷ Total clicks. Implied cost per 1,000 clicks multiplies that CPC by 1,000. It still uses clicks, while the CPM Calculator uses impressions.
What Target CPC - optional changes
Enter a target to add Gap vs. target (per click) and Gap vs. target (total spend) at the current click volume. Leave Target CPC - optional blank and the assumptions table shows Not entered and N/A for those rows. The warning appears when the absolute per-click gap is greater than 0.0005. The comparison leaves your inputs unchanged and does not recommend a bid.

Frequently asked questions
How do you calculate cost per click from ad spend and clicks?
Divide Total ad spend by Total clicks for the same period or campaign. The formula is CPC = Total ad spend / Total clicks.
What is the difference between CPC and CPM?
CPC divides ad spend by clicks. CPM divides ad spend by impressions and scales the result to 1,000 impressions. The implied cost per 1,000 clicks here uses clicks, so it is a different measure.
What does Target CPC - optional show?
Target CPC - optional shows the difference between the calculated CPC and the target per click and across the current click volume. Leave it blank to omit those comparisons.
Does the CPC Calculator use live ad data?
The CPC Calculator uses only the figures you enter. It does not fetch live rates or ad account records, and it processes your spend, clicks, target, currency, and period values locally in the browser.
