This is where customer churn rates come in. Churn rates can help you understand exactly how your business is doing and what your current customer turnover is.

If you don’t know how many customers your business is losing, you won’t be able to know about its impact on your business. Consequently, it will be difficult to devise plans and strategies to reduce turnover.

Although it sounds a bit scary, churn rate is quite a necessary metric. However, at times it can be difficult to calculate as well as deal with customer churn.

No need to worry, in this article, you will learn everything there is to know about churn rate, what it is, how to calculate churn rate and so much more.

What is Churn Rate?

Churn rate refers to the rate at which customers discontinue doing business with a company.

Maintaining a low churn rate can prove highly beneficial for a company. It allows you to grow and increase profits with minimum interruptions in your work processes.

Say in a subscription-based service, churn rate would account for how many customers choose not to renew their subscription, both before and after the subscription expires.

The rate applies to both customers who switch to another service as well as those who terminate their service without switching.

Different Types of Churn

There are two main types of churn — voluntary or active churn and involuntary or passive churn.

While both types of churn result in a loss of customers as well as revenue, their underlying factors and prevention measures are very different.

Voluntary Churn

Voluntary churn occurs as a result of customers actively terminating their own subscription. Owners of businesses tend to focus on churn of this kind.

This is because these customers make a conscious decision to leave behind your business.

Reasons why voluntary churn occurs

There are often many reasons behind customers’ decisions to leave, but some common ones are:

  • The clients’ experience failed to meet their expectations. Or, it failed to solve the problem they expected it would solve.
  • The customer was dissatisfied with your product/service. And, this resulted in them having to look for alternative solutions.
  • A competitor could have piqued their interest. Perhaps via a more appealing alternative that better suited their needs/budget.
  • A customer could be closing down operations or going out of business. As a result, they may no longer need your service.

In order to prevent as well as decrease voluntary churn, you need to focus on your customer-brand relationship. It is important to have a very good understanding of your customers’ opinions and feelings toward your products.

Make your product along with customer service invaluable as well as provide frequent value they are unable to live without. These are tried and tested ways to reduce revenue loss as a result of voluntary churn.

Involuntary Churn

Involuntary churn occurs when a business chooses to stop providing services to customers because they are not paying. When a customer’s payment attempt does not go through, without them realizing it, it ends in the cancellation of subscription.

Reasons why involuntary churn occurs

There are often many reasons behind businesses discontinuing service to customers, but some common ones are:

  • Expired cards
  • Hard Payment Decline. These are performed to prevent fraud when a card is lost or stolen.
  • Soft Payment Decline. This occurs when the card card has reached its credit limit.
  • Network Failures

Oftentimes, companies optimize their checkout pages in order to prevent involuntary churn.

In addition to this, they employ smart follow-up and collection strategies in order to communicate with customers and recover payments.

How to calculate Churn Rate?

Calculating churn rate can be quite simple really.

When calculating churn rate, you need to pick a time frame, like annually or monthly. Then, you must determine the total no. of customers at the beginning of the time frame, and the total number of lost customers as well.

Afterwards, you will have to divide the following:

Total no. of lost customers ÷ Total no. of customers at the beginning . Then, you have to multiply the answer by 100.

5 easy steps to remember when calculating churn rate:

  1. Decide on a timeframe — monthly, quarterly or annually.
  2. Determine the total number of customers at the outset of the period.
  3. Calculate the number of customers who churned (lost) by the end of the period.
  4. Divide the no. of lost customers by the no. of customers you initially had.
  5. Multiply your answer by 100.

For example, let us say that your company had 800 customers at the start of last quarter.

Unfortunately, you lost 100 customers because of poor customer service along with expired contracts.

This would make your quarter’s customer churn rate 100 churned customers divided by 800 former total customers, and 100 divided by 800 is 0.125.

Customer Churn Rate = (100 ÷ 800) × 100 Customer Churn Rate = (0.125) × 100 Customer Churn Rate = 12.5%

Multiplying this number by 100, you would get a customer churn rate of 12.5%.

Here’s how the mathematical calculation would look:

So, why does churn rate matter?

Churn rate is a very important metric that should be monitored by any subscription-based business. It helps you understand the long term stability of your business as well as forecast growth.

A high churn rate could negatively impact profits and impede growth.Thus, churn rate is a highly important factor in the telecommunications industry.

In most areas, many of these companies have stiff competition, making it easy for customers to shift from one to another.

Not only does churn include when customers switch carriers, it also includes when they terminate service without switching. Hence, this information can prove highly useful for subscriber-based companies, wherein subscription fees make up most of the revenue.

What is a good churn rate?

A good churn rate depends on the size of the company concerned as well as the industry in which it operates. Normally, the lower the churn rate is, the better it is for the business.

Small businesses commonly consider 5% per month to be a good churn rate. Meanwhile, larger companies aim for a much lower churn rate.

If there is a lot of competition present in a certain industry, this could lead to higher churn rate. This is due to many more options being easily available.

Churn Rate vs. Retention Rate

Churn Rate and retention rate are two metrics that businesses use to help them earn as well as retain customers.

Both of them are very useful in getting to know more about customer satisfaction in your business. They also help you learn more about how to maintain and improve it.

If you’re interested in building your customer base, learning about churn and retention rates can be extremely helpful.

You’ve already learnt about what churn rate is as well as how you can it, let’s take a brief look at retention rate now.

What is retention rate?

Customer rate refers to the extent to which a business keeps its existing customers. Basically, this number helps businesses ensure their marketing strategies and efforts to maintain customer satisfaction are effective.

A higher retention rate would also mean that your company can spend less time searching for new customers. Thus improving cost-effectiveness.

Furthermore, it can also lead to increased profits as customers are more likely to spend more on a service they trust.

How to calculate retention rate?

To calculate retention rate, you need three pieces of information. You should know how many customers you had at the beginning of a time period, how many there were at the end and exactly how many new customers signed up during the period.

Then, you have to first subtract the number of new customers from your total at the end of the period. Next, you will divide that number by how many customers you started with. Finally, multiply your answer by 100.

Customer Retention Rate = [(50,000–5,000) ÷ 45000] × 100 Customer Retention Rate = [1] × 100 Customer Retention Rate = 100% Thus, your retention rate for the year is 100%.

For example, say you started the year with 50,000 customers, added 5,000 new ones during and ended the year with 45,000 customers.

So, to calculate retention rate, you’d have to do the following:

What is a good retention rate?

An ideal retention rate is one that is as close to 100% as possible. This means that the business is keeping almost all of its customers .

In a similar way to churn rate, good retention rate would vary based on size of business and the industry in which it operates. Moreover, it can also depend on the age of your company.

A company that is more well-established may have higher retention rates. This is due to your service being well-known and customers understand what to expect from it.

In comparison, a younger company might have lower rates. This happens as customers are still currently testing and learning more about your service.

What’s the difference between churn rate and retention rate?

The main distinction between churn rate and retention rate is that the former calculates the percentage of customers lost by a business. Meanwhile, the latter calculates the percentage of customers a business keeps/retains.

In both of the cases, businesses aim to be close to one extreme, such as 0% for churn and 100% for retention.

However, the way businesses interpret these rates is different. A high churn rate is considered bad while a high retention rate is considered good.

Overall, both rates reflect levels of customer satisfaction. Furthermore, they both help businesses understand what they’re doing well and which strategies they can improve.


As you now know, churn rate measures the number of subscribers lost by a company in a given period of time.

If you want your company to grow, ensure that the number of new customers is higher than the number of customers lost in a given period of time.

Remember to keep in mind that every industry will have a different average churn rate. Companies can then compare their own with these to better understand their competitiveness.

Hence, you too need to calculate and keep a close eye on your churn to make sure it is properly under control and that your business thrives.
