What is Churn Rate?

Churn rate is the percentage of customers who stop doing business with you in a given period — monthly or annually. The formula is simple: customers lost in the period ÷ customers at the start of the period × 100. Annual churn of 5% means you lose 1 in 20 customers each year. The flip side, retention rate, is just 100 − churn rate.

Reducing churn starts with talking to customers before they leave — catching the confused, the stuck, and the about-to-cancel while you still can. Eloqra's live chat routes every visitor message to your Telegram, so at-risk customers can reach a human in one click instead of quietly churning.

Frequently Asked Questions

How is churn rate calculated?

Churn rate = (Customers lost during period ÷ Customers at start of period) × 100. Don’t include new customers acquired during the period in the denominator — only the ones you started with.

What is a good monthly churn rate?

For B2B SaaS, monthly churn of 1–2% is good and under 1% is excellent. B2C SaaS typically runs higher (3–8%). E-commerce subscription boxes often see 10%+ monthly churn.

What’s the difference between customer churn and revenue churn?

Customer churn counts the number of customers you lose. Revenue churn weights the loss by how much each customer paid. Revenue churn can be negative (good) if expansion from remaining customers outpaces lost revenue.

What is retention rate?

Retention rate is the inverse of churn rate: 100 − Churn %. If your monthly churn is 4%, your monthly retention is 96%. Annual retention compounds — 96% monthly is only ~61% annual.

How do I reduce churn?

Focus on the activation moment (does the customer get value in the first 7–14 days?), the at-risk signals (usage drop, support tickets), and the renewal moment. Survey detractors quickly and act on the top 3 themes.

How does live chat help reduce churn?

Most churn is quiet — a customer gets stuck, can't be bothered to open a ticket, and just leaves. A visible chat bubble gives them a one-click way to reach a human in the moment. Catching and resolving those small frustrations early is one of the cheapest churn-reduction levers there is.
