What this calculator estimates
Calculate blended CAC from marketing and sales spend.
How to use it
Enter Marketing spend ($); Sales spend ($); New customers acquired. Select Calculate to update the results.
How the calculation works
Add marketing spend and sales spend for the same acquisition period. Customer acquisition cost (CAC) = that total / new customers acquired. The ten-customer illustration multiplies CAC by ten.
Worked example: starting scenario
| Marketing spend ($) | 25000 |
|---|---|
| Sales spend ($) | 15000 |
| New customers acquired | 200 |
| Customer acquisition cost | $200.00 |
|---|---|
| Total acquisition spend | $40,000.00 |
| New customers | 200 |
| Cost per 10 customers | $2,000.00 |
Important limitations
New customers must be positive. Include the acquisition costs appropriate to your definition, such as allocated sales salaries or agency charges, in the entered totals. The tool does not allocate shared costs, adjust acquisition time lags, measure retention or establish customer lifetime value.
