Churn Rate Calculator

Calculate your customer and revenue churn rate with monthly, quarterly, and annual projections. Compare against SaaS benchmarks by company segment and estimate customer lifetime.

About this tool

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.

Frequently Asked Questions

What is a good churn rate for SaaS?

It depends on your segment. Enterprise SaaS should aim for under 1% monthly (under 10% annual). Mid-market SaaS targets 1-2% monthly. SMB SaaS typically sees 3-5% monthly. Early-stage startups often have 5-7% monthly churn while finding product-market fit. The goal is to consistently reduce churn over time.

How do I calculate monthly churn from annual churn?

The formula is: Monthly Churn = 1 - (1 - Annual Churn)^(1/12). For example, 36% annual churn equals about 3.6% monthly churn. Note that you cannot simply divide annual churn by 12 because churn compounds — each month you are losing customers from a smaller base.

What is the difference between voluntary and involuntary churn?

Voluntary churn happens when customers actively decide to cancel. Involuntary churn happens when customers lose access due to failed payments (expired cards, insufficient funds). Involuntary churn typically accounts for 20-40% of total SaaS churn and is the easiest to reduce with dunning email sequences.

How does churn affect customer lifetime value?

Customer lifetime is approximately 1 / monthly churn rate. At 5% monthly churn, average lifetime is 20 months. At 2% monthly churn, it is 50 months. Combined with average MRR, this gives you LTV. Reducing churn from 5% to 3% increases lifetime from 20 to 33 months — a 65% increase in LTV.

How can email marketing reduce churn?

Email reduces churn in several ways: onboarding sequences help new users find value quickly (reducing first-30-day churn), dunning emails recover failed payments (reducing involuntary churn by 10-20%), re-engagement campaigns bring back inactive users, and product update emails keep customers aware of new features they might otherwise miss.

Should I track customer churn or revenue churn?

Track both. Customer churn tells you how many accounts you are losing. Revenue churn tells you the financial impact. If revenue churn is higher than customer churn, you are losing higher-value customers — focus retention on larger accounts. If revenue churn is lower, smaller accounts are churning more — consider whether those accounts are a good fit for your product.
