CAC Payback Period

The time it takes to recover the cost of acquiring a customer through their gross margin.

Customer Success

Definition

CAC Payback Period is the number of months of a customer's gross-margin-adjusted revenue required to equal their acquisition cost. Short payback = efficient growth. Long payback = capital-intensive growth that strains cash flow.

Key points

  • Formula: CAC / (ARPU × Gross Margin)
  • Best-in-class SaaS: under 12 months
  • Reasonable: 12-24 months
  • >24 months signals capital inefficiency
Example

$5,000 CAC, $400/month ARPU, 70% gross margin: Payback = $5,000 / ($400 × 0.7) = 17.9 months.
