Churn Rate Calculator

Churn rate is the percentage of customers who cancel or stop using your product during a given period. For SaaS businesses, churn is the single most important metric to track because it directly determines your growth ceiling. Even a small change in monthly churn compounds dramatically over time — the difference between 3% and 5% monthly churn is the difference between retaining 69% and 54% of customers over a year.

Customer churn vs. revenue churn

Customer churn counts the number of customers lost. Revenue churn counts the dollar value of MRR lost. These can differ significantly. If you lose 10 customers but they were all on your cheapest plan, your revenue churn might be lower than your customer churn. Conversely, losing one enterprise customer can mean more revenue churn than losing 50 small accounts. Tracking both gives you a complete picture.

How churn connects to email marketing

Email is your most powerful tool for reducing churn. Onboarding sequences guide new users to their first success, reducing early churn. Dunning emails recover failed payments before they become involuntary churn (which accounts for 20-40% of all SaaS churn). Re-engagement campaigns bring back inactive users before they decide to cancel. Calculate the revenue impact of your email efforts with our SaaS Email ROI Calculator.

Benchmarking your churn

Acceptable churn varies by business segment. Enterprise SaaS companies typically see monthly churn below 1%, while SMB-focused products see 3-5%. Early-stage startups often have higher churn (5%+) as they find product-market fit. The key is understanding your segment's benchmark and working systematically to reduce churn over time. Even reducing monthly churn by 1% can double customer lifetime value.
