Cohort Analysis Tool

Analyse customer retention and optimise your marketing strategies

What is cohort analysis?

Cohort analysis is an advanced analytics technique that groups users who share common characteristics (usually their acquisition date) and tracks their behavior over time. This allows you to:

  • Identify retention patterns across different time periods
  • Measure the impact of product or marketing changes
  • Detect problems in user experience early
  • Optimize your retention and growth strategies

How to use cohort analysis

Cohort analysis is especially useful for:

Measure retention

Track what percentage of users acquired in a specific month continue using your product or service in subsequent months. This allows you to identify if you have retention problems and at what point users churn.

Evaluate product changes

If you launch a new feature or make changes to your product, you can compare the behavior of cohorts before and after the change to measure its real impact.

Optimize marketing strategy

Compare cohorts acquired through different channels to identify which sources bring users with best retention and lifetime value.

Practical example

A SaaS company notices that users acquired in Q1 have 80% retention at month 6, while users from Q2 only have 60%. Analyzing differences, they discover that Q2 lacked the onboarding process they had perfected in Q1.

Key metrics in cohort analysis

  • Retention Rate: Percentage of users who remain active over time
  • Churn Rate: Percentage of users who stop being active
  • Revenue per Cohort: Total revenue generated by each cohort
  • LTV per Cohort: Average lifetime value of users in each cohort
