Two of the most important metrics for SaaS teams to track are customer churn rate and customer retention rate.

These are the product analytics that let you know if you’re onboarding your most aligned customers, if your product is delivering a high-quality experience, if the features you’ve gone live with are the right ones, and so much more.

Let’s take a deep dive into these key metrics.

The Difference Between Churn Rate and Retention Rate

Customer churn rate is the percentage of customers that sign up and then leave within a given amount of time. Whereas customer retention rate is the percentage of customers that sign up and stay with you.

To put it simply, churn rate is bad because it means you’re losing customers, and retention rate is good because it means you’re keeping customers.

There are three major benefits to having a high customer retention rate and a low customer churn rate.

First, you’re likely spending money on new customer acquisition costs.

If you spend $100 on ads to generate one customer who pays you $50 per month, you need that customer to stay with you for at least 2 months to break even and 3 months to make money. If the customer leaves after month one you’ve just lost $50.

Second, a low churn rate and high retention rate means your customers are happy with your product.

It means you’ve identified a need in the market and you’re successfully filling it. Now it’s just up to you to keep innovating so you don’t lose your edge over any potential competitors that enter the market.

Third, having a high retention rate allows you to accurately predict your future revenue. This is important when it comes time to invest in expanding your team, increasing your ad budget, and enhancing your features or product suite.

A strong retention rate will help you feel confident that money will keep flowing in as you make these investments into the future of your company.

For all of these reasons, you need to be tracking your churn rate and retention rate and to know these numbers like the back of your hand.

It may sound obvious but your retention rate is your most important customer retention metric.

Metrics You Should Track to Determine Churn and Retention Rate

When getting ready to prepare a churn and retention rate report you’re going to want to have the following metrics ready:

  • Number of new customers onboarded in the last month
  • Number of new customers onboarded in the last year
  • Number of new customers who cancel after the first month
  • Number of new customers who cancel after the first year
  • Average number of months a customer remains a customer before canceling

If you lock your customers into annual contracts, as is common in the enterprise SaaS world, don’t worry about tracking how many customers cancel before the end of the first month.

However, if you offer a free month trial for your SaaS business before locking a customer into an annual contract, you should account for how many cancel before the trial is over to determine your Saas churn rate.

Retention Rate Formula and How to Calculate It

Calculating your customer retention rate, also sometimes referred to as renewal rate, is easy.

First, you want to determine the time period you’re looking at.

If you offer your services on a month-to-month basis it would make sense to look at both a monthly retention rate as well as your overall annual retention rate.

If you only offer services on an annual basis then you’ll just look at your annual retention rate.

To calculate your customer retention rate you’ll just want to determine the percentage of people who keep their account for the given period of time you’re looking at.

Customer Retention Rate Formula

For example, let’s say in May you brought in 1000 new customers and 50 of them canceled their accounts before the end of the month, which means you retained 950 customers.

950 is 95% of 1000 which means your monthly customer retention rate is 95% for May.

What is a Good Retention Rate?

If you’re wondering what a good customer retention rate is, you can start by looking at industry averages.

The average monthly churn rate for SaaS companies is 3-8% which would mean the average retention rate should be in the 92-97% range.

Additionally, we know that average annual churn is 32-50% which means the average retention rate should be in the 50-68% range.

That being said, it’s best not to compare yourself against the industry average.

Churn Rate Formula and How to Calculate It

There are two types of customer churn rates you’ll want to look at: voluntary churn and involuntary churn.

Voluntary churn is the number of people who unsubscribe for reasons of their own such as they are unhappy with the product or no longer need it.

Involuntary churn refers to the number of people who are unsubscribed due to things like payment failure.

At the end of the day, a churned customer is a lost customer, and you want to do everything you can to prevent it from happening.

That all starts with understanding how many customers you’re losing aka what your overall churn rate is.

The simplest way to calculate your customer churn rate is to use the basic churn calculation of:

Number of customers who left / total number of customers x 100

For example, if you had 1000 new customers in a given time period and 50 of them left without renewing their subscription, you would have a churn rate of 5%. Because 50 divided by 1000 is 0.05; multiply that by 100 and you get 5%.

Just like user retention rate, you’ll want to calculate your churn rate on a monthly, quarterly, and/or annual basis depending on how long your subscription agreements last for.

When calculating your customer churn rate you’ll likely want to look at not just the percentage of churn but the monthly recurring revenue (MRR) or annual recurring revenue (ARR) lost due to churn. This is considered your revenue churn.

This will help you get a better understanding of just how much net revenue churn is impacting your bottom line, and why even a “low” percentage like 5% could mean losing thousands of dollars each month.

Let’s say you sell a monthly subscription that costs $100 per month.

If you onboard 1,000 new customers each month you’re bringing in $100,000 in MRR.

If 50 of those 1000 new customers don’t renew at the end of the month your revenue churn rate is 5% like we previously discussed. Five percent is a low percentage, that sounds great. It means you’re retaining 95% of your customers!

However, losing 50 customers at $100 revenue per customer means you’re losing $5,000 in MRR each month.

You may be thinking at this point, “$5,000 isn’t so bad if I’m retaining $95,000 heading into the second month.”

This is why even a 5% churn rate is something to work hard at improving. If you can move the needle 1-2% you’re potentially keeping thousands of dollars.

This is exactly why it’s important not to get complacent even when your churn rate percentage looks good.

What’s a Good Churn Rate?

The average monthly churn rate for a Saas company is 3-8%, and the average annual churn rate is 32-50%.

If you don’t want to lose out on revenue it’s so important to make your product the very best it can be.

Be consistent with asking for feedback from your customers. Survey them after a month of use and gauge how they feel, and then send another survey after a few months and see if the response is still as positive.

If you know you get a lot of churn at one particular point in the customer journey. For example, if you see a lot of churn in month 2, then you’ll want to figure out why. Use feedback surveys, reach out to customers directly, and find out what’s going on so you can fix it.

Also, remember to always be innovating. You could have a great retention rate and churn rate one day and then a competitor disrupts the market and suddenly everyone is leaving your company for the new company.

While you can’t always anticipate a truly disruptive competitor, you can put customer loyalty programs in place to try and retain loyal customers in the event that a shiny new competitor comes into the space.

A strong customer loyalty program can help reduce churn and increase retention. This could be something simple as having a strong and personal account services team, or by sending customers quarterly gifts.

Investing in keeping your existing customers is just as important as signing new customers.

How Do You Stack Up?

Now that you know how to calculate your churn rate vs retention rate at their most basic levels - how do you stack up?

Are you currently sitting within or above the industry averages?

What plan can you and your product analytics manager come up with to be more data driven and increase your retention rate and reduce your churn rate?

Here’s a hint: you do both at the same time by staying focused on customer satisfaction.
