7 Customer Loyalty Metrics That Drive Retail Growth

In retail, tracking the right customer loyalty metrics is crucial for growth. These seven metrics give you actionable insights into customer behavior and help you build lasting relationships:

• Customer Retention Rate (CRR): Measures how well you keep customers over time.
• Customer Lifetime Value (CLV): Calculates the revenue a customer generates during their relationship with your business.
• Repeat Purchase Rate (RPR): Tracks how often customers return to make additional purchases.
• Net Promoter Score (NPS): Gauges customer satisfaction and likelihood to recommend your brand.
• Average Order Value (AOV): Shows the average spending per transaction.
• Redemption Rate: Examines how often customers use loyalty program rewards.
• Customer Effort Score (CES): Assesses how easy it is for customers to interact with your business.

Each metric offers unique insights to improve loyalty programs, increase repeat purchases, and boost revenue. For example, increasing retention by 5% can lead to profit growth of 25%-95%. Together, these metrics create a data-driven approach to understanding and enhancing customer loyalty.

The Top KPIs for Retailers to Measure

1. Customer Retention Rate (CRR)

Customer Retention Rate (CRR) shows the percentage of customers who stick with your business over a set time. It’s a clear measure of how well you keep your customers and maintain steady revenue.

Here’s the formula: CRR = ((Ending Customers - New Customers) / Beginning Customers) x 100

Let’s break it down with an example: If you start with 100 customers, gain 21 new ones, and end with 120, your CRR would be 99%. That’s a strong retention rate ^[2]. Generally, a CRR above 75% is solid, and hitting over 90% is outstanding - but benchmarks can differ depending on your industry ^[2].

Why is CRR so important? Keeping current customers costs less than finding new ones, making this metric a key indicator of your business’s overall health ^[1].

Here are some ways to boost your CRR:

• Improve customer service: Offer support across multiple channels and provide personalized help.
• Leverage data-driven marketing: Craft targeted campaigns based on customer behavior.
• Refine loyalty programs: Make adjustments based on what your customers value most.

Tracking CRR consistently helps you identify patterns and tackle problems early. While CRR tells you how well you’re retaining customers, pairing it with Customer Lifetime Value (CLV) gives you a fuller picture of their long-term worth.

2. Customer Lifetime Value (CLV)

Customer Lifetime Value (CLV) measures the total revenue a customer is expected to generate over their entire relationship with your business. It’s a key metric to identify your most profitable customers and decide where to focus your retention efforts.

Here’s the basic formula for CLV:

CLV = Average Order Value × Purchase Frequency × Customer Lifespan

For example, if a customer spends $100 per order, makes 4 purchases a year, and stays with your business for 3 years, their CLV would be $1,200.

According to research, 81% of businesses monitor CLV, underlining its importance in the retail sector ^[1].

CLV isn’t just about numbers - it’s a strategic tool. It helps allocate resources, create personalized experiences for your top customers, and spot potential churn by flagging declining CLV early on. In fact, increasing customer retention by just 5% can lead to a profit boost of 25%-95% ^[4].

Here are some ways to improve CLV:

• Use analytics to understand buying habits.
• Create tailored campaigns for your best customers.
• Strengthen loyalty programs and customer service to encourage repeat business.

Retailers can also use CLV insights to design loyalty programs that reward their most valuable customers, building lasting relationships. While metrics like CRR focus on retention rates, CLV goes a step further by showing the financial impact of keeping those customers. Plus, analyzing purchase frequency offers an even clearer view of customer loyalty.

3. Repeat Purchase Rate (RPR)

Repeat Purchase Rate (RPR) calculates the percentage of customers who make multiple purchases over time. This metric helps retailers spot trends that encourage repeat business, boosting both customer loyalty and revenue. The formula is simple:

RPR = (Number of Repeat Customers / Total Number of Customers) × 100

An RPR between 20-40% typically indicates strong customer retention. Repeat customers often spend more and are easier to convert. For instance, someone who makes a second purchase is 45% more likely to buy again, and this jumps to 56% after their fourth purchase ^[1].

Why does RPR matter? Because repeat customers are incredibly valuable. They spend 67% more per order compared to first-time buyers ^[3] and have a much higher chance of converting - 60-70% versus just 5-20% for new prospects ^[1].

Ways to Boost RPR

• Strategic Email Marketing
  Email remains a highly effective way to encourage repeat purchases. Personalized messages, reorder reminders, and exclusive offers can make a big difference. According to Litmus, "87% of brands say that email marketing is very critical to business success" ^[3].
• Loyalty Programs That Work
  Well-designed loyalty programs can keep customers coming back. In fact, 83% of consumers say these programs influence their buying decisions ^[3].

To track RPR, analyze customer purchase behaviors over specific time periods. For example, if you have 100 customers and 5 of them make repeat purchases, your RPR is 5%.

While RPR measures repeat buying behavior, Net Promoter Score (NPS) can show how likely customers are to recommend your brand, giving you deeper insights into loyalty.

4. Net Promoter Score (NPS)

NPS measures customer loyalty by asking: "On a scale of 0-10, how likely are you to recommend our company/product/service to a friend or colleague?" Based on their answers, customers fall into three groups: Promoters (9-10), Passives (7-8), and Detractors (0-6).

The formula to calculate NPS is straightforward: % Promoters - % Detractors.

In retail, an NPS above 20 is considered strong. With the industry average sitting around 15 (as reported by Bain & Company), this metric serves as an important benchmark for evaluating performance.

Use Feedback to Drive Improvements

Tracking NPS consistently with tools like Medallia can help uncover trends and assess the results of your improvement efforts. This feedback is a goldmine for refining products, enhancing service quality, and optimizing loyalty programs - all of which boost customer retention and revenue.

Practical Tips for Implementing NPS

• Track Regularly: Use tools designed for NPS tracking to monitor changes and spot patterns over time.
• Analyze Feedback: Pinpoint specific issues raised by customers. Retailers can use this insight to make targeted adjustments that improve scores and loyalty.
• Act on Responses: Reward Promoters, tailor experiences for Passives, and address Detractors' concerns. A systematic approach to resolving issues can significantly enhance customer satisfaction.

When paired with metrics like Repeat Purchase Rate, NPS offers a more complete view of customer loyalty. While NPS captures customer sentiment, Average Order Value (AOV) provides insight into how that sentiment impacts spending behavior.

5. Average Order Value (AOV)

Average Order Value (AOV) represents how much customers spend on average per transaction. It’s a useful metric for assessing the success of loyalty programs. To calculate AOV, divide your total revenue by the number of orders in a given period.

A higher AOV often indicates stronger customer trust and confidence in your brand. For context, the global AOV surpassed $110 in September 2023, serving as a benchmark for retail performance.

Ways to Boost AOV

• Product Bundling: Lively saw a boost in sales by bundling bras, with bundles accounting for 50% of purchases in just two weeks.
• Free Shipping Offers: Dae Hair increased AOV by offering free shipping and a 10% discount for orders over $70.
• Loyalty Programs: Claire's rewards program, which gives $5 cash back for every 100 points, encouraged larger purchases. Loyalty programs have been shown to raise AOV by up to 14% ^[3].
• Cross-Selling: Love Wellness suggests complementary products during checkout, leading to higher AOV and an improved shopping experience.

Tracking AOV

Keep an eye on AOV regularly to spot trends and opportunities:

• Daily during peak shopping periods like Black Friday or the holidays.
• Monthly for routine business tracking.
• Quarterly to uncover long-term patterns.

Customer trust plays a big role in how much they spend. Regularly tracking AOV helps retailers identify ways to grow revenue through loyalty-driven strategies.

While AOV focuses on spending per transaction, you can also measure Redemption Rate to see how engaged customers are with your loyalty rewards.

6. Redemption Rate

Redemption Rate measures the percentage of rewards that customers redeem. On average, the industry sees a rate of 13.67%, but top retailers can hit as high as 96%.

Understanding Your Redemption Rate

The formula is straightforward: (Rewards Redeemed ÷ Rewards Issued) × 100. For example, if 1,000 rewards are issued and 200 are redeemed, your Redemption Rate is 20%. Why does this matter? Higher redemption rates can lead to a 50% increase in sales, even after applying discounts.

Why Redemption Rates Matter

A low Redemption Rate can create financial risks - just look at the $100 billion in unredeemed points recorded in 2017. Plus, it impacts customer satisfaction. Redeemers are twice as satisfied compared to those who don’t redeem rewards.

Tips to Boost Your Redemption Rate

Here are some actionable ways to improve:

• Make redemption simple: Self-service options and clear account access can make a big difference. A 2018 survey showed customers who fully understand how to redeem rewards rate their satisfaction 87 points higher than those who don’t.
• Tailor rewards: Offer personalized incentives like birthday deals or customized offers to keep customers engaged.
• Use expiration dates strategically: Send reminders before points expire to encourage timely use and maintain goodwill.
• Stay in touch: Regular updates and reminders can help re-engage inactive members and keep your program top of mind.

Keeping Track of Performance

Check your Redemption Rate quarterly. A rate below 20% often indicates your program needs adjustments.

Streamlining the redemption process doesn’t just improve engagement; it also reduces customer effort, which ties directly to CES - a topic we’ll dive into next.

7. Customer Effort Score (CES)

Customer Effort Score (CES) gauges how easy it is for customers to interact with your retail business. Why does it matter? Because it directly ties to loyalty and sales. Research shows that 96% of customers who experience high-effort interactions lose loyalty, while low-effort experiences can increase loyalty by 22% and reduce churn by 15% ^[1][2].

Measuring CES Effectively

CES is typically measured through a simple survey using a 1-7 scale after customer interactions:

How to Make Customer Interactions Easier

• Simplify processes: Offer clear FAQs, self-service tools, and hassle-free digital returns.
• Empower your team: Train staff to resolve issues on the spot, eliminating the need for transfers or repeated explanations.
• Leverage technology: Use AI chatbots for instant responses and real-time inventory systems to reduce frustration.

The Role of Technology in CES

Technology can be a game-changer for reducing customer effort. Automated support systems help resolve issues quickly, while real-time inventory tracking ensures smoother purchasing experiences. These tools minimize the friction that often leads to customer dissatisfaction.

Measuring the Results

Pair CES with other loyalty metrics to see the bigger picture. For example, track how improved CES scores align with higher repeat purchase rates or increased customer lifetime value. This data will reveal which strategies are working best to keep customers coming back.
