# Churn Rate

Optimizing churn rate is one of the best ways to know if your business can create loyal customers for a certain period. By definition, the churn rate is the rate at which customers stop doing business with an entity (thanks, Investopedia!). More specifically, we like to look at it as how long you were able to maintain the interest of your customers. While the metric seems simple on the surface, it gives valuable insights into areas of future growth and improvement. We'll take you through how to calculate this metric, how to understand it in the context of your industry, and how to apply it to the platforms you're using now.

## How to Calculate Churn Rate

You can calculate the churn rate by dividing the number of churned customers by the total number of customers. Churn rate can be assessed for various time-periods (i.e. day, week, month, year) and, if your churn rate is tied to certain products or campaigns, you can assign a specific churn rate for each.

If you’re confused about how to define the number of churned customers and total number of customers, we’ve included some nifty definitions and examples below:

• Number of churned customers is the number of customers that leave a service/website/app at a certain period. This may include customers who downloaded an app but no longer use it or those who canceled their subscriptions.
• Total number of customers is the number of customers that you have during a period. This may be those who visited the website, availed service or plan, or downloaded the app.

There are also other ways of computing the churn rate of a business. The one above is the most basic way which can also be called customer churn. There is also gross dollar churn, which calculates the total revenues lost.

When choosing what to include in your calculations, remember: consistency is key! That means, if you decide to include XYZ in your churn rate for the month, you should include it in the next month’s churn rate as well. Having consistent metrics will allow you to better identify the causes of good or bad performance.

Again, as you begin (consistently) monitoring the churn rate, you’ll be able to find insights specific to your strategy. Of course, it’s also important to understand your churn rate in relation to your broader industry. To help you know what to expect, we’ve included a list of average churn rate per industry:

• Cable - 28%
• Retail - 27%
• Financial - 25%
• Online Retail - 22%
• Telecom - 21%
• Travel - 18%

Further, we've identified a popular platform that is particularly relevant to churn rate. This may be good place to begin if you’re getting started with this metric:

• Stripe: On this platform, you can calculate churn rate in Billing by counting the number of churned subscribers in the past 30 days and dividing it by the number of active subscribers as of 30 days ago and the number of new subscribers for the past 30 days.

## Tracking Churn Rate with Lido

If you don’t want to spend hours at the end of the month juggling numbers from your Stripe and other accounts, consider trying Lido. Lido can help you build a dashboard to monitor your data and give a look into how your key metrics (such as churn rate) change over time.
