Cohort Retention Curve

2026-05-31 8 min read

A cohort retention curve plots the percentage of customers from a given acquisition cohort (e.g., "January 2025") still retained at each subsequent month. The curve's shape — initial drop, plateau, and slope — diagnoses product-market fit (steep early drop = onboarding problem; flat plateau = sticky product; rising curve = expansion offsets churn). Cohort curves are the single best visualization of SaaS retention economics. Tools: Amplitude, Mixpanel, Heap, ProfitWell.
