How to use

Calculate average customer acquisition cost from total acquisition costs and new customers acquired in the same period.

  1. Enter Total acquisition costs.
  2. Enter New customers.
  3. Calculate, then review the results and method assumptions.

How it is calculated

CAC = acquisition costs ÷ new customers

Example

Acquisition costs of 2,400 for 80 new customers give CAC of 30. Including another 400 in agency costs changes the average to 35.

Important notes

Count newly acquired customers, not repeat orders. Document included costs such as ads, agency fees and acquisition staff. Compare consistent definitions; delayed sales can distort monthly comparisons.

Frequently asked questions

Should I use the number of orders?

Use unique new customers. A newly acquired customer placing two orders still counts once.

Can I calculate CAC with no new customers?

There is no finite average when dividing by zero. Enter a positive integer or record that no acquisition occurred.

Does this convert currencies or import campaign data?

It uses only entered numbers, without import or currency conversion. Align currency, period and metric definitions in your source before entering values.
