How to use this calculator

  1. Enter values with a consistent currency and reporting period.
  2. Calculate to see the result and supporting figures.
  3. Review the formula and assumptions before using the result.

The formula, explained

Campaign spend ÷ completed actions

Spending 600 for 30 actions gives a CPA of 20. Define the action before comparing campaigns: a newsletter signup, a qualified enquiry and a completed purchase are different outcomes.

Example inputs: campaign spend 600; completed actions 30. Result: 20 per outcome.

What to check before using the result

An action can occur more than once per customer. CPA is not automatically customer acquisition cost. Keep the attribution window, action definition and reporting period consistent.
