Blended CAC
What is Blended CAC?
DefinitionBlended CAC divides total sales and marketing spend by all new customers - including those from organic, referral, and brand - rather than isolating a single paid channel.
Formula
Blended CAC = Total sales & marketing spend ÷ All new customers (paid + organic)Blended CAC flatters paid performance because it folds in “free” organic customers, so always read it next to paid CAC. Across AdBoost Health partner accounts, blended CAC runs 30–50% below paid CAC once an organic engine (SEO, email, referral) is compounding: $60,000 of monthly spend acquiring 200 paid and 100 organic patients is a $200 blended CAC against a $300 paid CAC. The decision signal is the gap itself; if blended CAC drifts up toward paid CAC, the organic engine is stalling even while platform dashboards look stable.
