What is Cost Per Click (CPC)?

CPC is the amount an advertiser pays each time a user clicks on an ad. It equals Total Ad Spend divided by Number of Clicks.

How is CPC calculated?

CPC = Total Spend / Number of Clicks. Rearranged: Total Spend = CPC × Clicks, and Clicks = Total Spend / CPC.

A "good" CPC depends on industry, channel, and conversion value. For Google Search, average CPCs range from under $1 for broad niches to $50+ for competitive legal or finance keywords.

Is this tool accurate?

The math is exact given your inputs. Actual platform CPCs may differ slightly due to platform rounding or auction mechanics, but the formula is universally correct.
