Quick answer: Churn rate is the percentage of customers who stop doing business with you over a period. Divide customers lost by customers at the start of the period, then multiply by 100. Lose 5 of 100 customers in a month and your monthly churn rate is 5 percent.
Why churn rate matters
Every customer you lose is revenue you have to replace just to stand still. A business with a leaky bucket spends heavily on new sales while quietly bleeding existing customers. Tracking churn rate makes that leak visible — and cutting it is often the fastest, cheapest way to grow.
The churn rate formula
Churn rate = (customers lost ÷ customers at start) × 100
Pick a consistent period — usually monthly or annually — and apply the formula the same way every time so your trend is comparable.
A worked example
Suppose you begin the month with 200 customers and 8 of them cancel. Your monthly churn rate is (8 ÷ 200) × 100 = 4%. If that rate holds all year, you lose roughly 48 customers before accounting for compounding — a serious drag on growth that new sales must offset.
Customer churn vs revenue churn
Customer churn counts how many customers you lost. Revenue churn measures the rupee value lost. These can tell very different stories: losing ten tiny accounts might barely dent revenue, while losing one large account can be devastating. Track both alongside customer lifetime value for a complete picture.
How to reduce churn
- Spot at-risk customers early: watch for activity gaps and missed renewals.
- Automate renewal reminders: never let a renewal lapse silently.
- Follow up after support issues: a resolved complaint can build loyalty.
- Onboard well: customers who see value early stay longer.

Frequently asked questions
› What is churn rate?
Churn rate is the percentage of customers who stop buying from you or cancel their subscription during a given period, such as a month or year. If you start with 100 customers and lose 5 in a month, your monthly churn rate is 5 percent.
› How do you calculate churn rate?
Divide the number of customers lost during a period by the number of customers you had at the start of that period, then multiply by 100. For example, losing 8 of 200 customers in a month gives a churn rate of (8 / 200) x 100 = 4 percent.
› What is a good churn rate?
It depends heavily on industry and business model. For many subscription businesses, monthly churn under 2 to 3 percent is considered healthy, but a high-ticket B2B service can tolerate lower volumes with different benchmarks. Track your own trend rather than chasing a universal number.
› What is the difference between customer churn and revenue churn?
Customer churn counts how many customers you lost. Revenue churn measures the value of the revenue you lost. Losing one large account can hurt revenue churn far more than customer churn, so most businesses track both.
› How can a CRM help reduce churn?
A CRM flags at-risk customers through activity gaps, missed renewals and support history, so you can intervene before they leave. It also automates renewal reminders and follow-ups, keeping relationships warm. TatvaCRM helps Indian teams track renewals and retention in one place.
› Why is reducing churn important?
Retaining an existing customer is usually far cheaper than acquiring a new one, and loyal customers spend more over time. Even a small reduction in churn compounds into significant revenue and lifetime-value gains.
