What this calculator measures
Calculates average advertising cost per click.
Common use cases
Use this model when the inputs describe the same decision, period and customer or product scope.
- Calculate the average paid-traffic cost for a campaign, keyword group or advertising placement.
- Compare CPC with CTR and conversion rate to identify where the paid funnel is becoming inefficient.
- Use the same spend and click definitions when comparing platforms or attribution reports.
Formula
CPC = Advertising spend ÷ Clicks
CPC measures traffic cost, not customer or revenue value.
Worked example
$1,000 spend divided by 500 clicks equals $2.00 CPC.
How to interpret the result
Lower CPC indicates efficient ad targeting and high relevance.
Assumptions and limitations
- All clicks are valid and measured accurately.
