How to use the customer acquisition cost calculator.

Add the requested inputs

Use the labelled fields in the workspace above. If example values are provided, try them first or replace them with your own.

Calculate and review

Use the main action when needed. Total acquisition cost = marketing spend + sales spend. CAC = total acquisition cost ÷ new customers; daily cost uses the entered period length.

Try a worked example

£12,000 marketing spend plus £3,000 sales spend for 100 new customers gives a blended CAC of £150.

Check the assumptions

Agree which staff, software, agency and overhead costs belong in CAC, and match customers to the same period or acquisition cohort.
