Paid CAC

What is Paid CAC?

DefinitionPaid CAC isolates the cost of customers acquired specifically through paid advertising, excluding organic and referral, giving a true read on channel efficiency.
FormulaPaid CAC = Paid media spend ÷ Customers acquired through paid channels

Paid CAC is the number that tells you whether ad spend is actually working; blended CAC can look healthy while paid economics quietly break. In telehealth, track it by platform: a $180 Meta paid CAC next to a $320 Google paid CAC on the same offer usually points at the offer, not the channel. Benchmark it against your vertical rather than a universal number: across AdBoost Health partner accounts, blended CAC runs $150–350 for GLP-1 and $80–180 for hair and dermatology, with blended sitting 30–50% below paid once organic compounds, so a $250 paid GLP-1 CAC is comfortably inside range while the same number on a hair offer signals a broken funnel.
