There are different ways to calculate CAC.
Canaree calculates according to the following formula:
CAC = (sales staff + sales & marketing expenses) / # customers
When you've entered your sales staff and added marketing and sales expenses as well as generated a number of customers via the revenue builder your CAC will automatically be calculated and show up with your unit economics.
If you add, edit or remove expenses or staff in those categories the CAC will automatically be updated.
