What’s more important than acquiring customers?

NOT losing them (aka churn).

Today’s topic is how FP&A teams can calculate and reduce customer churn.

This post covers the following:

You can save your company from losing customers, which makes you a big winner when promotions are given. 🙌

Now, let’s talk about bathtubs.

What is customer churn?

Filling up a bathtub with water is like trying to grow your customer base. Bathtubs take time, effort, and money to fill.

But what happens when you try to fill a bathtub and don’t plug the drain?

You lose a lot of water.

And worse…the bathtub takes FOREVER to fill.

Customer churn is like water flowing through an unplugged drain. It happens when customers you worked so hard to acquire decide to say goodbye.

Examples of customer churn include:

❌Cancelled contracts

❌Closed accounts

❌Non-renewal of subscriptions

Churn makes growth harder, more expensive, and hurts the bottom line.

The CFO oversees accounting, cash flow, and financial planning, while the CRO is laser-focused on driving sales and boosting revenue. But that’s just scratching the surface.


Why is customer churn important?

Acquiring new customers is expensive and time-consuming.

These very reasons are why retaining customers is so important.

The longer you keep those customers, the more money you make from them.

Don’t waste all that acquisition effort.

Customer churn is also a leading indicator of major issues with:

  • The product you sell
  • The service you provide
  • The price you charge
  • The customer support you offer

Fix those issues ASAP and plug that leaky bathtub to accelerate growth.

Understanding customer churn rate

Customer churn rate is the % of customers lost during a certain period. The best companies look at churn monthly and annually, and they track it consistently every single month.

How is your customer churn rate trending?

Once you have the data at your disposal, it’s critical to investigate the drivers of and reasons behind churn.

Calculating customer churn rate

Investigation requires data to figure out WHO is churning.

To calculate the customer churn rate, you need three things:

  1. List of active customers at the beginning of the period
  2. List of active customers at the end of the period
  3. Flag customers that were active at the beginning and not active at the end

Let’s fire up the spreadsheet and look at an example below.

Churn example

Start with your list of customers going down and time periods going across as shown below:

churn example 1


Your company started with 10 active customers and ended with 13. That’s a change of three. Congrats! Your company grew. 🥳

Now, understand HOW your company grew.

Add a column to measure new customers. To do this, count any customers with a “+1” in the change column.

Add a coloumn to measure new customers

You added five new customers in the ending period.

But why did you only increase the customer count by three?

Answer: Churn

Add another column to measure churn customers.

To do this, count any customers with a “-1” in the change column.

Measure churn customers

You lost two customers to churn out of the original 10.

Your customer churn rate is 20%.

Customer churn rate = (2 / 10) = 20%

Let’s find out if that’s good or bad.

Interpreting customer churn

Customers will churn, it’s a fact of life.

To interpret your company’s customer churn, you’ll need to understand a few things.

Industry benchmarks

Every industry is different, so it goes without saying that churn rates will vary.

Do you know many people who have terminated their Microsoft subscription?

SaaS companies tend to have lower annual customer churn rates, typically in the single digits.

Do you know many people who have joined a gym, quit, and then joined another one?

Fitness companies tend to have annual customer churn rates as high as 40-50%.

Research your industry’s customer churn rate to understand how you stack up. This info is available on the web.

Or just ask ChatGPT. 😉

Then benchmark against your company’s churn rate.

Track history

Is your company’s churn rate improving or getting worse?

It’s a critical non-financial metric that should be reviewed consistently.

Review customer churn with your customer support team EVERY month. You’ll learn a ton and find ways to materially reduce future churn, i.e. DIRECT impact to the business.

Now you’re helping business partners hit essential business goals and marching towards that promotion.

Identify drivers

Build up a robust history of churn customers through your monthly reviews.

Now, work to understand WHY those customers are churning. You can create churn categories from this info.

Examples of churn reasons include:

  • Price
  • Support
  • Quality
  • Product/service not needed anymore

These categories allow you to take specific actions with your business partners. Trust us, they’ll love you for it and appreciate you helping them.

Strategies to reduce churn

You can’t go back in time to prevent the churn that happened. But you can look forward.

Use information from the past to reduce future churn and improve retention. There’s no shortage of areas you can focus on to plug that leaky bathtub.

Think about the products and services you use every day. What makes them great?

Improve customer experience

Customers have questions. Your company must be quick to address them.

The best customer support teams leverage case-tracking systems to manage incoming customer questions.

Track your customer support team’s case tickets:

  • How fast are they responding to the initial case question?
  • How long does it take to resolve the case entirely?
  • What was the customer’s feedback after the case was resolved?

Ideas to help your organization scale its customer support teams:

💡Reduce the number of cases raised by building a public Q&A / Help page that customers can access to address common questions.

💡Eliminate some customer questions altogether by creating thorough educational material for onboarding and ongoing use.

Note, however, that you should still expect case tickets. It means your customers are using your product or service.

Make the product better

Life is good when your customers are happy. Understand how they feel by measuring customer satisfaction.

You can do this by capturing your customers’ Net Promoter Score (NPS). Analyze these scores across customers and products, and then transform those unhappy customers into your biggest fans.

Add a personal touch

Every customer is different, so make them feel special. Personalization is key.

Segment them to tailor your communications and offers, and don’t be afraid to pick up the phone for an old fashioned chat. Human interaction goes a long way in building long-term relationships.
