  "description": "Fully-loaded sales-and-marketing (S&M) expense incurred to acquire one new customer during the period. Per the SMSB standard, the CAC numerator includes salaries + commissions + benefits + travel + marketing programs + tooling — i.e. all S&M costs, not just direct-attribution paid acquisition. The denominator is new logos, not deals. Common pitfall: omitting fully-loaded comp (especially BDR/SDR base salary and CS-team cost-of-sale where they participate in expansion) understates CAC and inflates every downstream efficiency metric. The board cares about CAC alongside CAC Payback and the CAC Ratio family — single-number CAC is a building block, not a verdict.",

  "formula": "CAC = Total fully-loaded S&M expense for the period / New Customers Added in the period. Per SMSB §CAC: numerator includes all S&M spend (compensation, benefits, programs, tooling, allocated overhead); denominator counts net-new logos only (not expansion deals).",
  "whyItMatters": "The cost side of the customer-unit economics ledger — paired with ACV and gross margin, determines whether each customer is a profitable transaction over a reasonable horizon. Boards read CAC alongside payback period before debating S&M investment levels.",
  "interpretationGuidance": "Absolute CAC values vary by ACV band — what matters is the ratio CAC / first-year-ARR (= New CAC Ratio) and CAC Payback. Per public SaaS comps, healthy CAC payback is < 24 months gross-margin-adjusted; > 36 months usually means the acquisition motion is either too expensive or the contract terms too short.",
