How do you measure customer loyalty?

Here are 11 top KPIs to help you measure customer loyalty: 

  1. Customer Retention Rate (CRR)
  2. Churn rate
  3. Repeat Purchase Rate (RPR)
  4. Purchase Frequency
  5. Monthly Recurring Revenue (MRR)
  6. Net Promoter Score (NPS)

1. Customer Retention Rate (CRR) 

Customer Retention Rate (CRR) is a vital metric that measures the percentage of customers who stick with a brand over a specific period. 

How to calculate it?

Customer Retention Rate = ((number of customers at the end of the period - new customers acquired) / number of customers at the beginning of the period) * 100

calculation of customer retention rate

Imagine a small online boutique with 10 customers at the beginning of the year who managed to retain 8 of those by the end of the year.

With only 2 customers lost, they achieved an impressive 80% customer retention rate.

A high CRR indicates strong customer loyalty and satisfaction. It implies that the brand is successful in delivering exceptional products, services, and experiences that keep customers coming back for more.

Conversely, a low CRR suggests that the brand is experiencing a higher rate of customer churn, potentially indicating issues with customer satisfaction or competitive pressures.

2. Churn rate

Churn rate measures the percentage of customers who discontinue their relationship with a brand over a specific period. It helps quantify customer attrition.

How to calculate it?

Churn Rate = (number of customers lost / number of customers at the beginning of the period) * 100

calculation of churn rate

For example, if a subscription-based service begins the month with 500 customers and loses 50 customers during that month, the churn rate would be 10% [(50 / 500) * 100]. 

A high churn rate indicates a significant loss of customers, potentially highlighting dissatisfaction, service issues, or intense competition. Conversely, a low churn rate indicates a higher level of customer loyalty and satisfaction.

3. Repeat Purchase Rate (RPR)

Repeat Purchase Rate (RPR) is a KPI that measures the percentage of customers who make multiple purchases from a brand within a given time frame. 

It provides insights into customer loyalty and the effectiveness of retention strategies. 

How to calculate it?

Repeat Purchase Rate = (number of customers who made repeat purchases / number of unique customers) * 100

calculation of repeat purchase rate

For example, if an e-commerce store had 1,000 unique customers and 400 of them made repeat purchases within a specified period, the Repeat Purchase Rate would be 40% [(400 / 1,000) * 100]. 

A high RPR indicates that a significant portion of customers is engaged and loyal, continually choosing to buy from the brand. It showcases customer satisfaction, product quality, and effective retention strategies. 

Conversely, a low RPR implies the need to focus on improving retention tactics and personalized marketing efforts.

4. Purchase Frequency

Purchase Frequency is a metric that tracks how often customers make purchases from a brand within a given time period. 

It provides insights into customer’s propensity to make repeated transactions.

How to calculate it?

Purchase Frequency = number of purchases / number of unique customers

calculation of purchase frequency

For example, if an online retailer had 1,000 unique customers and they made a total of 2,500 purchases within a month, the Purchase Frequency would be 2.5 (2,500 / 1,000). 

This means that, on average, each customer made 2.5 purchases during that month.

A high Purchase Frequency indicates that customers are actively engaged and making frequent purchases, highlighting their satisfaction with the brand. It suggests a strong customer base and potential for increased revenue. 

Conversely, a low Purchase Frequency may indicate the need for improved customer engagement strategies, personalized offers, or targeted marketing campaigns.

5. Monthly Recurring Revenue (MRR)

Monthly Recurring Revenue (MRR) measures the predictable and recurring revenue generated by a business on a monthly basis. 

It is commonly used by subscription-based or recurring revenue models. MRR helps track the stability and growth of a business over time.

How to calculate it?

Monthly Recurring Revenue = (average revenue per account) x (the total number of customers for that month)

calculation of monthly recurring revenue

For example, if a SaaS company has 100 active customers in a month, with an average monthly subscription fee of $50 per customer, the MRR would be $5,000 ($50 x 100).

A high MRR signifies a strong revenue base and customer retention, indicating a healthy business model. It demonstrates the ability to generate consistent and predictable revenue streams. 

On the other hand, a low MRR suggests the need to focus on improving customer acquisition, retention, or pricing strategies to increase recurring revenue and drive business growth.

6. Net Promoter Score (NPS)

Net Promoter Score (NPS) is a widely used KPI that measures customer satisfaction and loyalty by assessing their willingness to recommend a brand to others. 

It provides insights into customer advocacy and serves as a predictor of business growth.

How to calculate it?

NPS is typically calculated by asking customers : "On a scale of 0-10, how likely are you to recommend our product to a friend? "

Based on their responses, they are categorized into three groups: 

  • Promoters (score 9-10),
  • Passives (score 7-8), 
  • Detractors (score 0-6).

The NPS is determined by subtracting the percentage of Detractors from the percentage of Promoters.

Net Promoter Score = % Promoters - % Detractors

calculation of net promoter score

For instance, if a survey reveals that 50% of respondents are Promoters, 30% are Passives, and 20% are Detractors, the NPS would be +30 (50% - 20%).

A high NPS indicates a strong base of loyal customers who actively promote the brand, leading to positive word-of-mouth and potential customer acquisition. 

On the other hand, a low or negative NPS suggests the need to address customer concerns, enhance overall satisfaction, and improve the brand experience.

7. Customer Satisfaction Score (CSAT)

Customer Satisfaction Score (CSAT) tracks the level of satisfaction customers have with a specific interaction or transaction with a brand. 

CSAT offers immediate customer feedback, capturing sentiments right after a purchase or brand experience.

It focuses on the customer's emotional response, distinguishing it from NPS, which aims for a more rational assessment of the customer experience.

How to calculate it?

To calculate CSAT, customers are typically asked to rate their satisfaction on a scale of 1-5 or 1-10. It is then determined by taking the average rating of all customer responses.

Customer Satisfaction Score = (Sum of all customer ratings) / (Total number of customer responses)

calculation of customer satisfaction score

For example, if a survey collects 100 customer ratings with a total sum of 400, the CSAT would be 4 (400 / 100).

A high CSAT score indicates a high level of customer satisfaction, suggesting that customers are content with their experience and likely to become repeat customers. It reflects positive sentiments towards the brand, its products, services, and customer support. 

Conversely, a low CSAT score highlights the need to identify pain points and address customer concerns.

8. Average Order Value (AOV)

Average Order Value (AOV) helps tracking the average amount of money customers spend per transaction with a brand. 

How to calculate it?

Average Order Value = Total turnover / Number of orders

calculation of average order value

For example, if an e-commerce store generates $50,000 in revenue from 1,000 orders in a month, the Average Order Value would be $50 ($50,000 / 1,000).

A high AOV suggests that customers tend to make larger purchases. It may indicate successful upselling or cross-selling strategies, premium product offerings, or effective pricing strategies. 

Conversely, a low AOV may indicate the need to encourage customers to add more items to their cart, consider bundle deals, or introduce product recommendations to increase the order value.

9. Customer Lifetime Value (CLV)

Customer Lifetime Value (CLV) quantifies the projected total value a customer is expected to bring to a brand throughout their entire relationship. 

It helps businesses understand the long-term profitability of their customer base and shape strategic decisions regarding customer acquisition and retention.

How to calculate it?

Customer Lifetime Value = average order value * purchase frequency * customer lifespan

calculation of customer lifetime value

For instance, if the Average Order Value is $50, Purchase Frequency is 2 purchases per year, and the Customer Lifespan is 5 years, the CLV would be $500 ($50 * 2 * 5).

A high CLV indicates valuable, loyal customers who generate significant revenue over their lifetime.

On the contrary, a low CLV may indicate a need to focus on improving customer retention strategies, increasing repeat purchases, or enhancing customer satisfaction to increase their overall value to the business and maximize long-term profitability.

10. Upselling Rate

Upselling Rate measures the percentage of customers who accept and purchase higher-end products than the one intended, following your suggestions.

It quantifies the effectiveness of upselling techniques in driving customers to upgrade their selections and increase their average order value.

How to calculate it?

Upselling Rate = (number of successful upsells / number of suggested upsells) * 100

calculation of upselling rate

For instance, if a retail store offers upsell opportunities to 200 customers and successfully upsells 40 of them, the Upselling Rate would be 20% [(40 / 200) * 100].

A high Upselling Rate indicates that a significant proportion of customers are receptive to upselling, resulting in increased average order values and revenue per customer. It signifies successful persuasion techniques, effective product bundling, and customer willingness to trade up for higher-value offerings. 

Conversely, a low Upselling Rate may indicate the need to refine upselling strategies, improve product recommendations, or enhance the value proposition.

11. Reward Redemption Rate

Reward Redemption Rate tracks the percentage of customers who actively redeem the rewards or loyalty points they have earned within a given period. 

It provides insights into the effectiveness of a brand's loyalty program and the engagement level of customers with the available rewards.

How to calculate it?

Reward Redemption Rate = (number of rewards redeemed / number of rewards earned) * 100

calculation of reward redemption rate

For example, if a brand's customers earned a total of 1,000 loyalty points and successfully redeemed 500 of those points for rewards, the Reward Redemption Rate would be 50% [(500 / 1,000) * 100].

A high Reward Redemption Rate indicates active participation and engagement in the loyalty program, showcasing customers' appreciation for the rewards and their loyalty to the brand.

A low Reward Redemption Rate may suggest the need to evaluate the rewards offering, communication strategies, or program structure to encourage more customers to redeem their earned rewards.
