Churn Rate

The percentage of customers or revenue you lose over a given period.

What it means

Churn rate measures the rate at which customers cancel their subscriptions or stop paying. It comes in two flavors: customer churn (percentage of accounts lost) and revenue churn (percentage of MRR lost). Revenue churn is generally more important because losing a $500/mo customer hurts more than losing a $10/mo customer, even though both count as one in customer churn.

Formula

Customer Churn = (Customers lost in period ÷ Customers at start of period) × 100%

Why it matters

High churn kills SaaS businesses silently. Even if you're adding customers every month, a churn rate above 5-7% monthly will keep you on a treadmill. Reducing churn by even 1% compounds dramatically over time and is usually cheaper than acquiring new customers.

What is churn rate?

Churn rate is the percentage of customers (or revenue) that leave your product during a specific time period. It's the opposite of retention.

What is a good churn rate for SaaS?

For B2B SaaS, a monthly churn rate of 3-5% is average for early-stage. Best-in-class companies achieve under 2% monthly churn. Enterprise SaaS often targets below 1%.

How do you reduce churn?

Improve onboarding, increase product usage through education content, build sticky features, collect and act on feedback, and communicate product updates regularly.
