Retention Rate Calculator

Retention rate is the percentage of users, customers, employees, or members who remain active over a selected period. For product teams, it usually measures how many users return after starting.

Use the retained population at the end of the period divided by the eligible starting population, then multiply by 100. The exact inputs depend on whether the page measures customer, user, employee, or member retention.

A good retention rate depends on the business model, product frequency, and customer segment. Subscription and membership businesses usually need consistently high retention to protect recurring revenue.

Retention rate measures the share that stayed. Churn rate measures the share that left. Together they explain whether a customer or user base is becoming more stable.

Measure it at intervals that match the product cycle, such as weekly for high-frequency apps, monthly for SaaS, or annually for memberships.

Improve onboarding, activation, lifecycle messaging, product value delivery, and support quality. Segmenting retention by acquisition source or cohort helps identify where the loss is happening.
