Table 12 Sept 2026From “What is CAC?”

How should CAC be calculated and read across operating views?

Table 1How should CAC be calculated and read across operating views?

Route	Declare	Do not infer
Formula and calculation	Included acquisition costs, customer event, cohort, window, assignment status, and denominator	One formula is the universal accounting or causal standard
Strategy and interpretation	Budget or capacity decision, comparison, contribution horizon, and the companion measure	A lower ratio is automatically better growth or better value
Dashboard and data requirements	Cost source, customer key, start event, channel, market, plan, allocation rule, version, and unresolved fields	A complete chart proves the customer count, cost attribution, or counterfactual
Cohort, segment, and B2B	Offer, channel, market, buying process, implementation event, customer grain, and maturity window	A blended average transfers unchanged across segments or buying motions
Checklist and review	Owner, included and excluded costs, exception state, sensitivity, source, decision, and next date	A checklist creates an incremental result without a comparison design

Growth that compounds

What is CAC?

CAC is a defined cost per acquired customer, not a universal ratio. State the cohort, boundary, horizon and counterfactual before comparing channels.
