Monthly & Annual Churn

Calculate both monthly churn and extrapolated annual churn from a single data entry. Three analysis modes to fit your needs.

Customer Lifetime

Revenue at Risk

Quantify exactly how much MRR or ARR is at risk from churn — the data you need to justify retention investment.

Cohort Analysis

Analyze how a specific customer cohort has retained over time — more granular than aggregate churn rate.

Understanding Churn Rate & Its Business Impact

Churn is the single most important health metric for subscription businesses.

What Is Churn Rate?

Churn rate is the percentage of customers who stopped subscribing to a service in a given period. The formula is: Churn Rate = (Customers Lost ÷ Customers at Start) × 100.

For SaaS and subscription businesses, churn is a leading indicator of growth health. A company can acquire many new customers but still shrink if churn outpaces acquisition.

What Is a Good Churn Rate for SaaS?

For B2C SaaS, monthly churn of 3–5% is common but concerning; under 2% is excellent. For B2B SaaS, monthly churn under 1% (annual under 10%) is the target. Enterprise SaaS should aim for under 5% annual churn. High churn (above 5% monthly) typically signals product-market fit or onboarding issues.

Churn Rate & Customer Lifetime Value

Churn rate directly determines average customer lifetime: Lifetime = 1 ÷ Monthly Churn Rate. A 5% monthly churn means customers stay an average of 20 months. Combined with average revenue per customer, this gives you LTV — the critical metric for determining sustainable customer acquisition costs.

Why Reducing Churn Is Your Highest-ROI Activity

Reducing churn by even 1% can dramatically increase company value and growth rate.

Compounding Retention

Keeping customers longer means exponentially more revenue per customer — and it costs 5–10x less than acquiring new ones.

Higher Company Valuation

SaaS companies with lower churn are valued at higher revenue multiples because predictable recurring revenue is more valuable.

Better Product Signals

Analyzing churn reasons reveals the most critical product gaps and feature requests — direct input for your roadmap.

FAQ

Churn Rate Questions Answered

Everything you need to know about measuring and reducing customer churn.

What is a good churn rate for a SaaS company?

For SaaS, monthly churn under 2% is considered good, with best-in-class companies achieving under 1%. Annually, that translates to under 10–11%. B2B SaaS typically has lower churn than B2C because switching costs are higher and contracts are longer. Early-stage startups often see higher churn (5–10% monthly) as they work toward product-market fit, while mature SaaS companies target 1–3% monthly.

How is monthly churn rate calculated?

Monthly Churn Rate = (Customers Lost During Month ÷ Customers at Start of Month) × 100. For example, if you had 1,000 customers at the start of July and lost 30, your monthly churn is 3%. Note that new customers acquired during the month are generally excluded from the denominator for a cleaner measurement of retention behavior among your existing base.

What is the difference between customer churn and revenue churn?

Customer churn measures the percentage of customers who leave. Revenue churn (also called MRR churn) measures the percentage of revenue that churns. They differ when customers pay different amounts. You can have positive net revenue churn (good) even with some customer churn if remaining customers expand their plans enough to offset losses. Net Revenue Retention (NRR) above 100% is the gold standard for SaaS growth.

How do I reduce customer churn?

Key strategies: improve onboarding to drive early activation and habit formation; implement proactive customer success outreach, especially for at-risk accounts; collect and act on churn reason data; build in-product health scores to identify disengaged users early; create loyalty programs for long-term customers; and ensure pricing tiers align with value delivered. Segmenting churn by customer type, plan, and cohort reveals where to focus first.

How do I convert monthly churn to annual churn?

The precise formula is: Annual Churn = 1 – (1 – Monthly Churn Rate)^12. For a 3% monthly churn: 1 – (0.97)^12 = 1 – 0.694 = 30.6% annual churn. A common shortcut of multiplying monthly churn by 12 overestimates because it doesn't account for the compounding effect — each month's churn applies to a smaller base. This calculator uses the correct compound formula.
