Did you know? Increasing customer retention by just 5% can boost revenue by 25–95%. Yet, 44% of businesses don’t measure retention effectively.

What is Customer Retention Rate (CRR)?
CRR measures how well a business keeps its customers over time. It’s calculated using this simple formula:
Retention Rate = ((E – N) / S) × 100

  • E: Customers at the end of the period
  • N: New customers during the period
  • S: Customers at the start of the period

Why does it matter?

  • Retaining customers is 5-30 times cheaper than acquiring new ones.
  • Loyal customers are 60-70% more likely to purchase again.
  • Top-performing businesses aim for retention rates of 70–90%.

Example Calculation:
If a business starts with 130 customers, gains 23 new ones, and ends with 144 customers:
((144 – 23) / 130) × 100 = 93% retention rate.

Industry Benchmarks:
Retention rates vary by sector. For example:

  • Media & Entertainment: 84%
  • SaaS: 68%
  • Hospitality: 55%

Key Takeaway:
Tracking and improving CRR is essential for growth. Focus on enhancing customer experience, offering loyalty programs, and personalizing communication to keep customers coming back.

How to calculate your customer retention rate (CRR)

Customer Retention Rate Formula

Measuring retention rate accurately is essential for understanding how well a business keeps its customers. Let’s break down the key components of the formula and how it works.

Core Components of the Formula

The formula for customer retention rate relies on three main variables:

Retention Rate = ((E – N) / S) × 100

Where:

  • E: Total number of customers at the end of the period
  • N: Number of new customers acquired during the period
  • S: Number of customers at the start of the period

This formula intentionally focuses on existing customers by excluding new ones gained during the period, providing a clear picture of how well the business retains its original customer base.

Example Calculation

Let’s look at an example using Astro’s numbers: Astro started the month with 130 customers. They lost 9 customers but gained 23 new ones, ending the month with 144 customers .

Plugging these values into the formula:
((144 – 23) / 130) × 100 = 93%

This means Astro retained about 93% of its starting customers, which highlights the effectiveness of their retention efforts.

Adjusting the Formula for Different Industries

Different industries tweak the formula to account for their unique characteristics. Here’s a quick look at how retention rates vary across sectors:

Industry Type Average CRR Key Focus Areas
Media & Entertainment 84% Subscription renewals and user engagement
Professional Services 84% Client satisfaction and project completion
Commercial Insurance 83% Policy renewals and long-term relationships
SaaS 68% Monthly/annual subscription renewals
Hospitality & Travel 55% Repeat bookings and loyalty programs

For example, SaaS companies prioritize reducing churn and tracking subscription renewals. Service-based industries often emphasize client satisfaction and successful project outcomes, while product-focused businesses might monitor repeat purchases or warranty renewals .

Reading Your Retention Results

Understanding Your Numbers

Customer Retention Rate (CRR) is a key indicator of how satisfied your customers are and how well your business is performing. A high retention rate means customers appreciate what you offer, while a low rate suggests areas that need improvement .

Here’s why retention matters: retained customers are 60-70% more likely to make additional purchases, compared to just 5-20% for new customers . Knowing your retention numbers helps you measure success against these benchmarks:

Retention Level Rate Range What It Means
Excellent 90%+ Customers are loyal, and your service delivery is outstanding.
Good 75–89% Relationships are strong, and retention strategies are effective.
Average 60–74% There’s room to enhance the customer experience.
Poor Below 60% Immediate action is needed to address customer satisfaction.

Use this table to see how your retention rate stacks up and identify areas to refine.

Industry Standards

The average retention rate across all industries is 72.5% , though this varies widely depending on the sector:

Industry Sector Average CRR How It Compares
Media & Entertainment 84% Among the best performers.
Professional Services 84% Top tier in retention.
Insurance 83% Strong results.
IT Services 81% Performing well.
Banking 75% Matches the overall average.
Hospitality 55% Needs significant improvement.

If your retention rate falls below these industry benchmarks, it’s time to evaluate your approach.

Areas for Improvement

Here are three areas to focus on for better retention:

  • Customer Experience and Service Quality: Did you know that 88% of customers value their experience as much as the product itself ? Make sure your team is trained to resolve issues quickly and effectively.
  • Service Excellence: With 89% of companies citing customer service as critical to retention , investing in better support systems and team training is a must.
  • Feedback Implementation: Regularly gather and act on customer feedback. Addressing issues early can prevent churn and build trust.

Methods to Increase Retention

Looking to keep your customers coming back? These practical strategies can help strengthen loyalty and reduce churn.

Improving Customer Service

Great customer service can make all the difference. In fact, 55% of customers are willing to pay more for better service .

Service Area How to Improve Benefits
Response Speed Offer 24/7 support channels Minimizes frustration, lowers churn
Support Options Provide chat, email, and phone support Makes help easily accessible
Documentation Create self-service resources Allows customers to solve issues quickly

Take Superhuman as an example. They provide personalized onboarding to help users understand the product’s value right away .

Loyalty Programs That Work

Loyalty programs can significantly boost customer retention, with some studies showing they drive revenue growth by 2.5x . Here are two standout examples:

  • Marriott Bonvoy: A tier-based program where members earn and redeem points for stays, meals, and experiences .
  • Nothing Bundt Cakes: A simple punch card system offering a free cake after 12 purchases .

These programs show that whether simple or more structured, rewarding your customers can build stronger relationships.

Clear and Personalized Communication

Customers value communication that feels personal. 71% of consumers expect personalized interactions . Focus on these key areas:

  • Proactive Updates: Keep customers informed with real-time updates about service changes or improvements.
  • Personalized Content: Personalization can increase revenue by 40% . For instance, Ahrefs includes product usage tips in their blog content .
  • Educational Resources: Webflow’s tutorial videos teach both design principles and platform usage, helping customers succeed while deepening their connection to the product .

Retention Rate Calculation Errors

Getting your retention rate calculations right is essential for reliable business insights. Mistakes – whether caused by incorrect timeframes, averaging across segments, or mixing up metrics – can lead to misleading conclusions.

Time Period Mistakes

The timeframe you use for retention calculations matters. Many companies rely on arbitrary periods instead of focusing on signup cohorts, which can distort results. For instance, early-stage businesses often experience higher initial churn that stabilizes over time .

Here’s how to avoid common time period errors:

  • Focus on signup cohorts: Track retention based on when users signed up (e.g., weekly or monthly cohorts) instead of calendar-based periods.
  • Account for business stage: Recognize that retention patterns differ for new customers versus long-term users.
  • Stick to consistent timeframes: Don’t mix different periods in your calculations.

As a benchmark, here are retention rates businesses should aim for over the long term :

Business Type Target Retention Rate
Consumer Free Products 40%
Consumer Subscription 50%
B2B Small Business 60%
B2B Enterprise 90%

Now, let’s dive into the problems caused by averaging across customer groups.

Customer Group Errors

Averaging retention rates across different customer segments can lead to major miscalculations. Research shows that this approach can undervalue one-year customer revenue by more than 52% .

Here’s an example to illustrate :

A company had two customer groups, each with 100 users. One group had a 90% monthly retention rate, while the other had just 10%. Averaging these rates (50%) led to an annual revenue estimate of $3,984.38. However, calculating each group separately revealed the true value: $8,285.70.

This highlights the importance of segmenting your customer groups. Beyond this, mixing retention metrics can also skew your analysis.

Metric Mix-ups

Confusing similar metrics – like monthly and annual retention rates – can create significant errors. For example, a 5% monthly churn rate might seem small, but it actually compounds to a 46% annual churn rate .

Here’s a breakdown of key metrics:

Metric What It Measures Typical Range for SaaS
Monthly Retention Rate Percentage of customers retained month-over-month 92-97%
Annual Retention Rate Percentage of customers retained year-over-year 50-68%
Revenue Churn Revenue lost from downgrades or cancellations Varies by industry

To ensure accuracy, track these metrics separately and avoid using them interchangeably. For SaaS companies, monthly churn typically falls between 3-8%, while annual churn ranges from 32-50% . Understanding these distinctions is key to making informed decisions about retention.
