Customer Acquisition Cost (CAC): GrowthBar vs Hadrian
DIRECT ANSWER
Customer acquisition cost (CAC) is the total sales and marketing spend required to acquire one new paying customer, calculated as total acquisition spend divided by new customers acquired in the same period. It is a primary efficiency metric for growth teams, typically evaluated alongside LTV to determine whether customer economics are sustainable. GrowthBar addresses customer acquisition cost (cac) as a tool you prompt manually; Hadrian's agents execute it continuously on your live brand data under your approval gate.
What customer acquisition cost (cac) means in practice
The standard CAC formula is: total sales and marketing spend ÷ number of new customers acquired, measured over the same time period (monthly or quarterly). Fully-loaded CAC includes salaries and benefits for sales and marketing staff, agency and contractor fees, ad spend, tool and software costs, and event costs — not just media spend. Blended CAC mixes all channels; paid CAC isolates spend on paid acquisition only. Both are useful; the distinction matters when evaluating channel efficiency.
For marketing teams, customer acquisition cost (cac) is a lever that needs consistent, ongoing execution — not a one-off task. The question is whether your tooling runs it continuously or requires manual effort each time.
