Retention Rate

How to Calculate Retention Rate: Essential Business Metrics

Retention rate is the percentage of customers who continue using a product or service over a specified time period. This statistical measurement quantifies the proportion of people that remain involved with a group from one time period to another. Businesses across various sectors track this metric to evaluate customer loyalty and operational performance.

The concept of retention rate applies to numerous contexts, including marketing, investment, education, employee management, research, and clinical trials. In marketing specifically, retention rate counts customers and their activity regardless of the transactions they make. According to a survey of nearly 200 senior marketing managers, 63% found the retention rate metric very useful.

For subscription-based businesses particularly, retention rate shows the extent of a company’s revenue regardless of whether they acquire new clients. This metric is less relevant for businesses that sell products to customers only once over a long period, such as car manufacturers, unless they offer ongoing services like warranties or maintenance agreements.

The standard formula for calculating retention rate is:

Retention Rate = ((Number of customers at the end of the period − Number of new customers acquired during the period) / Number of customers at the start of period) × 100

For example, if you start with 105 customers, acquire 20 new ones during a month, and end with 95 customers, your retention rate would be 71%:

(95-20) / 105 = 0.71

• 0.71 × 100 = 71%
• Retention rate is inversely related to churn rate, which measures the percentage of customers who stop using your product. If a company has a 90% retention rate, its churn rate is 10%. When retention rate exceeds the acquisition rate, the product gains users (and generally revenue) over time. Conversely, a retention rate lower than the acquisition rate results in a net loss of customers.

Beyond revenue considerations, businesses use retention rate to understand:

Customer loyalty levels

• Quality of customer experience
• Value users derive from the product
• Sustainability of their business base
• Some companies define retention based on product usage rather than subscriptions alone. This approach considers two key aspects:

The product’s critical event – an action users take that indicates value (e.g., playing a song on Spotify)

1. The product’s usage interval – how often a customer performs the critical event
2. Generally, high retention corresponds to a positive outcome across all contexts. For instance, in mobile app marketing, retention rates are typically measured at specific intervals (day 1, day 7, or day 30) to gage user engagement and the app’s ability to deliver value over time.

Why is Retention Rate Important for Businesses?

Measuring and improving retention rate offers substantial financial benefits for businesses across all sectors. Companies with high retention rates reduce acquisition expenses significantly, as it costs five times more to acquire new customers than to retain existing ones. This cost efficiency extends beyond marketing budgets, directly impacting profitability—research from Harvard Business Review demonstrates that increasing customer retention by merely 5% can boost profits by 25% to 95%.

Financial advantages extend beyond cost savings. Loyal customers typically spend more over time, with existing customers 50% more likely to try new products and spending 31% more than new customers. Furthermore, loyal customers are 5 times more likely to make repeat purchases, 4 times more likely to refer others to the brand, and 7 times more likely to try new offerings.

Revenue stability represents another crucial benefit of strong retention. Higher retention rates provide predictable revenue streams, allowing for more accurate forecasting and strategic planning. For many businesses, this stability is essential—notably, for 61% of small businesses, repeat customers account for more than half of their annual income.

The connection between retention and institutional knowledge preservation cannot be overstated. Organizations with high employee turnover risk losing valuable insights and proven skills that veteran team members contribute, especially during critical moments. This loss of knowledge can significantly slow business operations and hinder responsive decision-making during crises or opportunities.

For subscription-based models, retention directly correlates with business sustainability. SaaS companies consider a monthly retention rate of 95% (representing 5% churn) as generally favorable. Additionally, in the customer lifetime value calculation, higher retention extends customer lifespan, increasing overall value—each loyal subscriber can contribute substantial revenue over their lifetime.

Retention also impacts operational efficiency. Constantly replacing departing employees leads to productivity gaps and morale challenges. High turnover forces managers to focus on hiring rather than team development, leaving existing employees feeling neglected. Moreover, steady workforce turnover damages company culture and disrupts team cohesion, creating cascading effects on performance.

Brand reputation benefits significantly from strong retention as well. Customers notice when businesses experience high turnover rates, which may raise concerns about company stability. Conversely, businesses known for retaining employees build reputations as excellent workplaces, strengthening their employer brands and attracting top talent.

Ultimately, retention serves as a critical indicator of business health across multiple dimensions. Whether tracking customer or employee retention, this metric provides invaluable insight into satisfaction levels, operational effectiveness, and future growth potential. Organizations that prioritize retention strategies position themselves for sustained success while avoiding the costly cycle of continually replacing valuable relationships.

How to Calculate Retention Rate

Calculating retention rate requires a systematic approach to ensure accurate results. This metric helps businesses track customer loyalty over specific time periods. The following four-step process provides a clear methodology for determining your retention rate.

Step 1: Identify starting customers

Initially, determine the total number of customers at the beginning of your measurement period. This establishes your baseline for comparison. Count only existing customers who were active on day one of your chosen timeframe. For business analysis, this period might be monthly, quarterly, or annually depending on your industry and reporting needs. Exclude any customers who joined after the period began, as this would artificially inflate your retention calculations.

Step 2: Count new customers during the period

Subsequently, track the number of new customers acquired throughout your measurement period. This includes all new additions to your customer base between the start and end dates. It’s essential to maintain accurate records of customer acquisition timestamps to properly categorize them as new additions. These customers must be identified separately because they weren’t part of your initial customer base and therefore aren’t being “retained.”

Step 3: Count customers at the end of the period

Next, determine the total number of customers at the conclusion of your measurement period. This represents your final headcount before calculations begin. The end-period figure includes both retained customers from your original cohort and newly acquired customers who joined during the timeframe. This total customer count provides the raw data needed for the formula’s numerator.

Step 4: Apply the retention rate formula

Finally, apply the standard retention rate formula:

Retention Rate = ((Number of customers at end of period – New customers acquired during period) ÷ Number of customers at start of period) × 100

This calculation isolates precisely how many original customers remained with your business. For instance, if you began with 1,000 customers, gained 200 new ones during the quarter, and ended with 1,150 customers total, your calculation would be: (1,150 – 200) ÷ 1,000 × 100 = 95%.

Alternatively, this can be expressed as:

Retention Rate = 1 – Churn Rate

Where the churn rate represents the percentage of customers lost during the period. Businesses should calculate retention rates consistently across comparable timeframes to establish meaningful benchmarks. This methodical approach enables companies to accurately assess customer loyalty trends and evaluate the effectiveness of their retention strategies.

Different Types of Retention Rate

Retention rates apply across various domains, each with its unique characteristics and benchmarks. Understanding these different contexts helps organizations interpret their metrics appropriately and set realistic goals.

Customer retention rate

Customer retention rate measures the percentage of customers a business maintains over a specific timeframe. This metric is particularly crucial for subscription-based companies, where it directly reflects service value and customer satisfaction. In financial services, customer retention rates average 78%, with the banking industry slightly lower at 75%. This high rate correlates with customer behavior—the average American uses their primary bank account for 16 years. Nevertheless, industry standards vary significantly, with retail averaging around 63% and hospitality, travel, and restaurants showing the lowest average at 55%.

App retention rate

App retention rate tracks the percentage of users who continue engaging with an application after installation. This metric is typically measured at specific intervals—day 1, day 7, and day 30 post-download. The calculation divides monthly active users by monthly installs. Industry data shows concerning trends, with approximately 21% of users abandoning apps after just one use. Consequently, developers employ various strategies to improve retention, including re-engagement ads, push notifications, and user segmentation tools. The average retention rate for app users hovers around 35%, highlighting the challenge of maintaining user engagement in the mobile ecosystem.

Student retention rate

Student retention rate represents the percentage of students who remain enrolled in educational programs over time. In school systems, retention rates typically decrease as education levels advance—85.4% for primary (Classes I to V), 78% for elementary (Classes I to VIII), 63.8% for secondary (Classes I to X), and 45.6% for higher secondary (Classes I to XII). In higher education, retention focuses on keeping students actively enrolled in their degree programs. Factors affecting student retention include academic support services, personalized learning experiences, and early intervention systems for at-risk students.

Employee retention rate

Employee retention rate calculates the percentage of staff members who remain with an organization throughout a specified period. To determine this metric, divide the number of employees at period-end by the number at period-start, then multiply by 100. In the United States, the average employee retention rate is approximately 90%, although this varies by industry. Primarily, retention issues stem from workplace culture, limited career development opportunities, and compensation concerns—with 80% of potential departing employees citing poor culture or management as their main stressor. High retention rates correlate with reduced recruitment costs, preserved institutional knowledge, and improved productivity. However, effective employee retention strategies can help curb the issues and challenges.

Retention Rate vs Churn Rate

Retention rate and churn rate represent two sides of the same coin, measuring opposite aspects of customer behavior. Fundamentally, these metrics exist in an inverse relationship—as one increases, the other decreases proportionally. When combined, they always sum to 100%, providing complementary insights into business performance.

Churn rate measures the percentage of customers lost during a specific timeframe, whereas retention rate quantifies the percentage of customers who continue using a product or service. This mathematical relationship can be expressed as:

Retention Rate = 100% – Churn Rate

Both metrics function as indicators of customer satisfaction and loyalty. A high retention rate suggests customers find value in the provided product or service, while an elevated churn rate signals potential issues requiring attention. For subscription-based businesses particularly, these figures serve as critical performance indicators.

The metrics differ in their focus and application. Retention rate emphasizes customer loyalty and the success of retention efforts. In contrast, churn rate highlights customer attrition and identifies areas needing improvement. Industry leaders often maintain an average customer retention rate of approximately 94% (corresponding to a 6% churn rate), though benchmarks vary significantly across sectors.

Various industries exhibit different standard retention rates:

Insurance companies: 84%

• Banking: 75%
• Retail: 63%
• Hospitality and travel: 55%
• SaaS: 35%
• Media: 25%
• Fintech: 37%
• Edtech: 4%
• For SaaS companies specifically, the average monthly churn rate ranges between 3-8%, translating to retention rates of 92-97%. However, when measured annually, average churn increases to 32-50%, meaning retention rates of 50-68%.

These metrics offer distinct business insights. Retention rate correlates with increased customer lifetime value, revenue growth, and profitability. Simultaneously, churn rate can reveal warning signs in service or product experience. Together, they provide a comprehensive view of customer behavior patterns, enabling businesses to make informed strategic decisions about their operations.

How to Improve Your Retention Rate

Implementing effective strategies can drastically improve your retention rates across all business contexts. Consider these proven approaches to strengthen customer relationships and minimize churn.

Use customer feedback

Customer feedback serves as a goldmine of insights for enhancing retention. Collecting feedback at multiple touchpoints enables businesses to identify areas for improvement and address issues before they lead to customer churn. Implementing a comprehensive feedback loop process that includes gathering responses, adding tags, creating tasks, taking action, and following up with customers ensures customers feel valued. Companies that act on customer feedback, like Intercom, have successfully reduced their monthly churn from 5.5% to just 1.5%.

Improve onboarding experience

A quality onboardingexperience keeps new users engaged and committed. Employees with exceptional onboarding experiences are 2.6 times more likely to be satisfied with their workplace. Likewise, for products, guiding users quickly to their “aha!” moment fundamentally changes their relationship with your offering. Effective onboarding should work like a funnel, moving from universal knowledge to role-specific information.

Send re-engagement emails

Re-engagement emails target inactive subscribers to recapture their interest and boost retention. These emails remind customers of positive past experiences while rebuilding trust without resorting to hard selling. Benefits include reduced churn, increased customer lifetime value, and improved email delivery. Effective formats include “We Miss You” messages, incentive emails, product updates, feedback requests, and countdown emails creating urgency.

Offer loyalty rewards

Loyalty programs directly increase customer retention by encouraging existing customers to remain with the company. These rewards make customers feel appreciated while providing valuable data for personalization. Research shows 68% of consumers would pay more for brands they’re loyal to. Effective loyalty programs should align with company strategy, understand member preferences, and deliver high perceived value through exclusive access or experiences.

Personalize user experience

Personalization significantly drives retention and loyalty over time. Companies that grow faster generate 40% more revenue from personalization than slower-growing counterparts. Studies indicate businesses offering personalized experiences can improve customer retention by up to 56%. Effective personalization requires leveraging customer data, creating accurate segments, delivering consistent omnichannel experiences, and establishing feedback mechanisms to refine strategies.
