15 Customer Retention Metrics and 7 Ways To Boost Customer Retention

What is customer retention?

Customer retention is any business's or product's ability to retain customers to do business with them again. It is crucial in any SaaS business since it is harder to make new customers than keep existing customers engaged. Customer retention metrics give detailed insight into how a product or company performs while retaining its older customers. It also keeps track of the customer journey which helps in growth and expansion strategies.

Why is tracking retention KPIs important?

Let's consider a SaaS company that provides a project management tool to businesses. They aim to retain as many customers as possible and increase revenue. The company needs to measure the percentage of customers using its software to create an effective customer retention strategy.

Now consider the company is left with 80 customers at the end of its first year (started with 100 customers). Therefore, the company's retention rate is 80%. However, the retention rate drops to 60% the following year, meaning 60 customers continue to use their tool at the end of the second year. There could be a lot of reasons for this decline, such as the product does not offer value, poor customer service, etc.

This example tells how tracking customer retention metrics can allow a SaaS company to use insights about its performance.

SaaS businesses rely on the revenue generated from the subscriptions from their older customers rather than from new customers because of their product's value. Customer retention is imperative in a subscription-based business model. Thus, tracking customer retention rate is the best way for SaaS businesses to determine how loyal customers are to their brands and reduce customer churn.

In addition to revenue growth, customer retention metrics are essential for gauging business stability and growth, customer loyalty, cost savings, and performance evaluation.

14 essential customer retention metrics to track

Let's look at the most critical customer retention KPIs to understand your product's strengths and weaknesses.
1. Customer retention rate (CRR)

• What is CRR?

The customer retention rate is the percentage of how many users stick with your product after their initial purchase.

• Why is CRR important?

CRR is vital because it helps companies determine their products' performance and their business's profitability.

• How do you calculate CRR?

You need the following formula to calculate CRR:

CRR = (A/B)100%

A= The number of loyal customers at the end of a period, i.e., (Number of customers at the end of a specific period - Number of newly acquired customers)

B= Total number of customers at the beginning of that period.

2. Monthly recurring revenue  (MRR)

• What is MRR?

MRR is the metric that offers insights into the monthly revenue generation of a SaaS company. MRR predicts the future revenue of any SaaS business, which can be helpful for any product's or service's performance measures over time. It is widely found in subscription-based models as well for tracking financial growth.

• Why is MRR important?

MRR is a valuable metric for SaaS companies as it represents the recurring revenue generated by each subscriber per month. As a result, companies can see how their revenue grows and make informed decisions about their business.

• How do you calculate MRR?

Simply multiply the number of active customers by their average monthly revenue.

MRR= No. of active customers * Average monthly revenue per customer



If a SaaS business has 200 active customers and their average monthly subscription cost is $100, their MRR is $20,000 (200 active customers * $100/customer/month).




MRR finds the recurring revenue of the current monthly customers; Therefore, if some more customers are subscribed, the MRR will change accordingly. Assuming the company acquires ten new customers next month that pay $200 per month on average, we will add the new revenue to the old revenue to get the new MRR:


$20,000 + (10 new customers * $200 per customer) = $22,000 MRR

3. Customer lifetime value (CLTV)

• What is CLTV?

The customer lifetime value metric tells the expected revenue from a single customer as long as they use the business's product or service. A high CLTV represents the customer's loyalty to the business and even identifies the most crucial customers.

• Why is CLTV important?

Businesses can use this metric to understand how much the cost of acquiring a customer should be. This metric can also give insights for the business to make strategies as to how the customer acquisition cost should be reduced.

• How do you calculate CLTV?
To calculate customer lifetime value, the formula is as follows:

CLTV = Average Revenue per Customer * Average Customer Lifetime

Let's say a company has a software product with an average monthly revenue per customer of 60$. Also, if the average customer lifetime is 24 months, the customer lifetime value CLTV will be $1440 ($60 * 24). It indicates that, on average, $1440 will be generated as revenue from each customer over the lifetime.

4. DAU to MAU rate

• What is the DAU/MAU rate?

This essential customer retention metric is known as Daily Active Users to Monthly Active Users rate (DAU to MAU) and helps find how much the customers use a product regularly.

• Why is the DAU/MAU rate important?
Knowing how much the customers use a product in the SaaS business. It provides information about the product's "stickiness" and finds the value it creates for the users. Any business needs to understand the customer engagement level.
• How do you calculate the DAU/MAU rate?
To find the DAU to MAU rate, divide the number of Daily Active Users by the Monthly Active Users.

Let's say a company has 400 DAU and 5000 MAU; then the DAU to MAU rate will be 8% ((400/5000) * 100).

5. Repeat purchase rate

• What is the repeat purchase rate?

The repeat purchase rate is used to find the customers who make repeat purchases from the total of the business's customer base.

• Why is the repeat purchase rate important?

This metric is crucial for SaaS businesses to find customers that engage the most with the product and are more likely to purchase the product again.

• How do you calculate the repeat purchase rate?

Simply divide the number of customers who repeat purchases more than once by the total number of customers in the same time frame. Let's say a company has 400 total customers, and from that total, 200 make repeat purchases; then the repeat purchase rate can be calculated as follows: Repeat purchase rate = 200/400 = 0.5100 = 50%

6. Expansion MRR

• What is expansion MRR?

It measures the product's additional customer revenue via upsells, cross-sells, and add-ons. The additional revenue can be generated by upsells when customers switch from a low to a high-priced plan. Cross-sells also bring in revenue, which means purchasing additional products offered by the same business. Similarly, purchasing add-ons and reactivation can also lead to revenue growth.

• Why is expansion MRR important?

Expansion MRR is significant for businesses since increasing the CLTV of already retained customers is much more cost-effective than acquiring new customers. Revenue generated from the existing customers also indicated customer loyalty.

• How do you calculate expansion MRR?

To calculate the expansion MRR, first find the difference between the expansion MRR at the end of the month and the expansion MRR at the beginning of the month. Then divide the above difference by the expansion MRR at the beginning of the month.

Expansion MRR rate(in percentage)= [(Expansion MRR at the end of the month - Expansion MRR at the beginning of the month)/ Expansion MRR at the beginning of month] * 100

If a business has a $300 expansion MRR at the beginning of the month and the expansion MRR at the end of the month is $500, then the expansion MRR can be calculated as:

The expansion MRR rate = [ ( 500 - 300 ) / 300 ] * 100 = 66.7%

Businesses can use this information for future decision-making and effective product growth.

• How do you calculate the customer satisfaction score?

You can calculate this score with surveys by asking customers to rate their level of satisfaction on a scale. Then, divide the number of happy customers by the total number of customers who took the survey.

8. Net Promoter Score (NPS)

• What is NPS?

To measure customer loyalty, Net Promoter Score is the best metric.

• Why is NPS important

It allows businesses to determine whether the customer will recommend its product or service to others.

• How do you calculate NPS?

It is measured by asking customers to rate whether they are likely to recommend the product to others on a scale of 0-10. The customers who score from 9-10 are called promoters. People who score from 7-8 are known as passives, while the ones who score less than 6 are detractors.

The Net Promoter Score is the difference between the number of promoters' and detractors' percentage values. Let's say the result of a survey revealed the promoters to be 40% of the respondents while 25% people were detractors since they scored below 6. So, the Net Promoter value will be 15%.

9. Customer health score

• What is the customer health score?

The customer health score allows businesses to identify customer churning by evaluating their well-being and engagement with the product or service.

• Why is customer health score important?

Using this metric, businesses can get information regarding customer loyalty, whether they will stay with the business or cancel the subscriptions. Tracking this customer retention metric is crucial as it helps to identify customer success or failure patterns.

• How do you calculate the customer health score?

• Why is the revenue churn rate important?

By tracking revenue churn, businesses can better understand the financial impact of customer churn on their revenue and make informed decisions to improve customer retention by identifying areas for improvement.

• How do you calculate the revenue churn rate?

The formula to calculate the revenue churn rate is as follows: (Customer Churning MRR loss / MRR at the beginning of the month) * 100. A business with an MRR of $8000 loses $1200 MRR due to customer churn. Then, the revenue churn rate will be :( 1,200 / 8,000 ) * 100 = 15%

11. Existing Customer Revenue Growth Rate

• What is the Existing Customer Revenue Growth Rate?

It is the rate at which your business generates revenue from customer success.

• Why is the existing customer revenue growth rate important?

Understanding how different product features perform can help diagnose the parts of the product that are frequently used and even those that are underutilized.

• How do you calculate the feature adoption rate?

Feature adoption rate is calculated by dividing the number of specific feature users by the total number of users. Assume 5000 people out of 10000 users have used some specific feature. Then the feature adoption rate of that specific feature will be 50% (( 5000 / 10000 ) * 100).

13. Renewal rate

• What is the renewal rate?

The Renewal rate is the rate at which the customers renew their subscription after their initial contract is expired.

• Why is the renewal rate important?

For a business offering its product in a subscription model, it is crucial to know how many customers are re-subscribing to its product. The Renewal rate also indicates the customer-retaining power of a business. Customer satisfaction is also found using the Renewal rate data. A high rate shows the customers are satisfied with the product, and a low value indicates that the product needs to be more valuable for the customer.

• How do you calculate the renewal rate?
