Why Conventional CAC Calculations Fall Brief
Earlier than diving into the components, let’s handle why most CAC calculations miss the mark. Conventional approaches sometimes isolate every channel:
- Paid Adverts CAC: Advert spend ÷ clients acquired via adverts
- Content material CAC: Content material prices ÷ attributed conversions
- Companion CAC: Partnership charges ÷ referred clients
This siloed method ignores the fact of recent buyer journeys. A buyer would possibly uncover your model via content material, analysis on social media, and eventually convert via a paid advert. Whereas it is a win, it does not give the total story on its success. What different data might be left unconsidered, like, “Which channel will get credit score?” or, “How do you account for model advertising that helps all channels?”.
The reply lies in calculating blended CAC and true CAC, which account for multi-channel complexity.

$230 (Blended CAC) = $115,000 (Complete Spend) ÷ 500 (New Prospects)
Whereas blended CAC supplies a useful benchmark, it does not assist you to optimize particular person channels or allocate funds successfully.
