2026-05-31 7 min read

Payback period is the time required to recover the cost of acquiring a customer through their gross-margin-adjusted revenue. For SaaS: CAC / (ARPA × Gross Margin %). Expressed in months. Best-in-class B2B SaaS: <12 months. Mid-market enterprise (>$50K ACV): 12–18 months acceptable. PLG/SMB: should target <6 months. Payback period is the single most important capital-efficiency metric for venture-backed SaaS in 2026.
