Calculate your exact customer churn rate using your starting customers, new acquisitions, and end-of-period count — then benchmark against SaaS standards.
Enter your customer counts for the period you want to analyse.
Enter your customer counts for the period — starting customers, new customers acquired, and total at end — to see your churn rate and annualised impact.
Get your exact churn rate in under 30 seconds. Enter three customer counts and instantly see your monthly churn, annualised impact, and benchmark rating — no spreadsheets needed.
Input the total number of paying customers at the beginning of your period — month or quarter. This is the denominator the churn formula is built on.
RequiredEnter how many new paying customers you added during the same period. This separates fresh acquisitions from the customers you started with.
RequiredInput your total paying customers at the end of the period. The calculator subtracts new acquisitions to isolate exactly how many original customers churned.
RequiredInstantly see your churn rate, customers lost, retained, and acquired — plus annualised churn and a colour-coded benchmark rating against SaaS standards.
InstantChurn compounds silently — measure it consistently and catch problems before they become expensive.
Track churn every month to catch upward trends before they compound into serious revenue loss.
Measure churn before and after a pricing update, feature change, or UI redesign to isolate the impact.
Churn rate is one of the first metrics investors ask about. Know your number and have a credible reduction plan ready.
Use your churn rate as a key input when projecting MRR — without it, your growth forecasts are dangerously optimistic.

Run the calculator separately for different customer segments or acquisition cohorts to find which groups retain best.
Everything you need to know about churn rate, SaaS benchmarks, revenue churn, and how to reduce customer loss.
Churn rate is the percentage of customers (or revenue) lost during a given period. A 5% monthly churn rate means 5 out of every 100 customers cancelled that month.
For B2B SaaS, monthly churn below 1% is excellent. 1–2% is good. 2–5% is average but sustainable with strong acquisition. Above 5% monthly is high and signals a retention problem. Enterprise SaaS typically sees 0.5–1% while SMB-focused products often see 2–4% monthly.
Customer churn counts the number of customers lost. Revenue churn (MRR churn) measures the percentage of monthly recurring revenue lost. Losing one large enterprise customer can produce high revenue churn with low customer churn. Tracking both gives you a complete picture of retention health.
Annual churn is not simply monthly churn × 12 — that overstates the problem. The correct formula accounts for compounding:
The most common causes are poor onboarding (customers never reach the value moment), product-market fit issues, pricing misalignment, poor customer support, competitive switching, and involuntary churn from failed payments. Identifying which category your lost customers fall into is the essential first step to reducing churn.
Negative churn (net negative churn) occurs when revenue expansion from existing customers — through upsells, cross-sells, or seat growth — exceeds revenue lost from churn. It means your existing customer base grows in value even without new acquisition, making it the most powerful growth lever in SaaS.
Involuntary churn is customer loss from failed payments — expired cards, insufficient funds, or billing errors — rather than intentional cancellation. It typically accounts for 20–40% of total churn. Automated dunning emails, smart payment retries, and card updater services can recover a large portion of this revenue.
The highest-impact tactics: improve onboarding so customers reach their value moment faster, add proactive CS outreach for at-risk accounts, build product stickiness through integrations, offer annual contract incentives to reduce monthly opt-out windows, and fix involuntary churn through automated dunning and payment retry logic.
