Customer Acquisition Cost (CAC) for Fractional CMOs
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. For Fractional CMOs, this is especially relevant because running marketing strategy for multiple clients simultaneously with minimal personal bandwidth.
What customer acquisition cost (cac) means for Fractional CMOs
A fractional CMO juggles 2–5 clients at once — each with its own brand voice, channels, and KPIs. The bottleneck is execution bandwidth, not strategic clarity. Every hour spent on production is an hour not spent on strategy.
For a fractional CMO, customer acquisition cost (cac) is a lever you need but rarely have time to execute consistently. 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.
