See how many of your customers actually stick.

Cohort retention groups customers by when they joined — a month, a quarter — and tracks what share of each group remains active over time. Because everyone in a cohort started together, you can compare how the January cohort looks after six months against how the June cohort looks after six months, holding the timeline constant. That comparison reveals whether the customers you're winning now retain better or worse than before, which a single blended churn number can't show because it mixes cohorts of different ages together.

A blended churn or retention figure can drift for reasons unrelated to product quality — a surge of new customers, a change in customer mix, or seasonality — masking what's really happening to the people you serve. Cohorts isolate each group so you can see the true shape of retention over time and whether changes you've made are working. If newer cohorts retain better than older ones, your improvements are landing; if worse, something has slipped. That clarity is why cohort analysis is the standard way to study retention.
