Formula
Blended CAC = Total Marketing Spend / Total New Customers
Blended CAC shows the average cost to acquire one customer across your full marketing program. Unlike narrower channel-level CAC, it helps you judge whether the overall growth system is becoming more or less expensive as a whole.
How to use this calculator
- 1Enter total marketing or acquisition spend for the period you want to review.
- 2Enter total new customers acquired in that same period across the whole business or acquisition program.
- 3The calculator divides total spend by total customers to estimate blended CAC.
What this metric tells you
Blended CAC is useful for top-level growth review because it cuts through channel-by-channel noise and shows overall customer acquisition cost.
A healthy channel-level CAC does not always guarantee a healthy blended CAC if weaker channels or overhead are dragging the mix down.
This metric is strongest when paired with blended revenue efficiency metrics like MER and unit-economics metrics like LTV:CAC.
Common use cases
- Checking whether the total acquisition program is becoming more expensive over time.
- Comparing overall customer acquisition efficiency across months or quarters.
- Pressure-testing top-level growth economics before diving into channel detail.

Worked example
Example: calculating blended CAC from total spend and customers
If total marketing spend is $18,000 and total new customers are 120, blended CAC is $150.00. That means the business spent about one hundred and fifty dollars per new customer across the full acquisition program.
FAQ
What is blended CAC?+
Blended CAC is the overall cost to acquire a new customer across your full marketing program, not just one campaign or one channel.
How is blended CAC different from standard CAC?+
Standard CAC can be measured narrowly or by channel. Blended CAC emphasizes the all-in, top-level customer acquisition cost across the whole acquisition mix.
Why can blended CAC worsen while some channels still look efficient?+
Because strong channels can be offset by weaker ones, rising overhead, or broader spend that does not convert into customers efficiently at the blended level.
Should I track channel CAC and blended CAC together?+
Yes. Channel CAC helps with optimization, while blended CAC helps you understand whether the whole growth system still works economically.
