CAC Calculator
Use this CAC calculator to estimate average customer acquisition cost over a defined period. CAC is most useful when the spend and customer count use the same time window.
Formula
- CAC = sales and marketing spend / number of new customers
Example calculation
If sales and marketing spend is $15,000 and 120 new customers are acquired in the same period, CAC is $125 per customer.
FAQ
What costs should be included in CAC?
Common inputs include ad spend, sales tools, marketing software, agency costs, and sales or marketing labor for the same measurement period.
What if no new customers were acquired?
CAC cannot be calculated by dividing by zero. The calculator will ask for at least one new customer.
Is lower CAC always better?
Not always. CAC should be considered with customer quality, retention, payback period, margin, and lifetime value.
