Understanding Retention Analysis in SQL

Retention analysis is a crucial metric for any data-driven team aiming to measure how often users return to a product or service over time. Analysts, marketers, and product managers frequently use SQL to perform retention analysis—identifying trends, pinpointing where users drop off, and guiding efforts to improve customer lifetime value. However, crafting an accurate SQL retention analysis query can get complex, especially as datasets grow and cohort definitions evolve.

When Should You Use a Retention Analysis Query?

Typical scenarios for running a SQL retention analysis query include:

  • Measuring new user retention by week or month

  • Comparing cohorts based on signup date, campaign, or geography

  • Evaluating long-term customer engagement

While SQL is powerful, manually writing these queries can be tedious and error-prone—especially for non-experts.

Example: SQL Retention Analysis Query

Prompt:

Suppose you want to track the percentage of users who return each week, based on their signup date. Here’s a simple SQL query example for retention cohort analysis:

SELECT
  DATE_TRUNC('week', signup_date) AS cohort_week,
  DATE_TRUNC('week', event_date) AS activity_week,
  COUNT(DISTINCT CASE WHEN signup_date = event_date THEN user_id END) AS new_users,
  COUNT(DISTINCT user_id) AS retained_users,
  ROUND(100.0 * COUNT(DISTINCT user_id) / NULLIF(COUNT(DISTINCT CASE WHEN signup_date = event_date THEN user_id END), 0), 2) AS retention_percentage
FROM user_events
GROUP BY 1, 2
ORDER BY 1, 2;

This query groups users by their signup week and shows how many were active in subsequent weeks—the essence of retention reporting.
