Definition

Cohort-based LTV estimates lifetime value using observed retention and gross profit over time for a cohort, rather than a simple churn formula.

How to use it

  • More accurate when churn changes over time or expansion is meaningful.
  • Use cohorts by plan/channel to avoid mixing behaviors.

Measured as

Measure Cohort-based LTV on the same customer segment, time window, and revenue basis each time you review it.

Operator takeaway

  • More accurate when churn changes over time or expansion is meaningful.
  • Use cohorts by plan/channel to avoid mixing behaviors.
  • Keep Cohort-based LTV consistent by cohort, segment, and period before you use it as a decision signal in planning or reporting.
  • Interpret the metric alongside retention, margin, or payback so one ratio does not hide the real operating trade-off.

  • Read Cohort LTV forecasting: churn, expansion, discounting (practical model) if the decision depends on interpretation, policy, or trade-offs beyond the raw formula.
