Retention Rate
Retention rate is the percentage of users or customers who remain active over a given period, measuring how well a product keeps the people it already acquired.
In depth
Retention is the compounding force behind durable growth, because acquiring users only pays off if they stick around long enough to deliver value and revenue. You measure it over a chosen window, such as monthly or annually, and can track it by logo, revenue, or engagement, each telling a different story about stickiness. High retention also lowers the pressure on acquisition, since you are not constantly refilling a leaking bucket, which makes every marketing dollar work harder.
The common pitfall is averaging retention across very different cohorts, which hides the fact that some segments churn fast while others stay for years. Cohort analysis and segment-level views reveal where the product truly fits. In a lead-qualification workflow, a scorecard quiz protects retention upstream by filtering for fit: scoring prospects on need and readiness means you acquire customers more likely to succeed and stay, rather than poorly matched signups who churn within weeks.
Example in practice
Frequently asked questions
How do you calculate retention rate?
Take the number of users active at the end of a period who were also present at the start, divide by the starting count, and exclude new users added during the period. Express the result as a percentage over your chosen window.
What is the difference between retention rate and churn rate?
Retention rate measures the share of users who stay, while churn rate measures the share who leave; together they sum to 100 percent for a cohort. Tracking both gives a fuller picture of how your base is changing.
Why is retention rate so important for SaaS?
Recurring revenue models depend on customers staying long enough to exceed their acquisition cost. Strong retention compounds growth and reduces how aggressively you must acquire new users.
