Did you know that increasing customer retention by just 5% can boost profits by 25–95%? And while repeat customers make up only 8% of buyers, they contribute 40% of annual revenue. Tracking the right metrics can help you build loyalty, reduce churn, and grow your business.

Here are the 7 key customer retention metrics every eCommerce brand needs to monitor:

• Customer Lifetime Value (CLV): Measures how much revenue a customer generates over their lifetime.

• Customer Churn Rate: Tracks the percentage of customers who stop buying from you.

• Repeat Purchase Rate: Shows how often customers return to make another purchase.

• Average Order Value (AOV): Calculates the average amount spent per transaction.

• Customer Retention Rate (CRR): Measures the percentage of customers who stay with your brand over time.

• Net Promoter Score (NPS): Gauges customer satisfaction and loyalty.

• Customer Engagement Score (CES): Tracks how actively customers interact with your brand.

Quick Tip: Start by focusing on CLV and churn rate to understand your revenue potential and where you might be losing customers.

These metrics aren’t just numbers - they’re tools to help you improve customer experiences, increase loyalty, and drive long-term growth. Let’s break them down and explore strategies to optimize each one.

Customer Retention & Churn Rate for Ecommerce

1. Customer Lifetime Value (CLV)

Customer Lifetime Value (CLV) represents the total revenue a customer brings to your business throughout their relationship with your brand. Surprisingly, while 89% of companies acknowledge its importance in driving loyalty, only 42% measure it accurately.

For eCommerce brands, the average CLV stands at $168. However, this number can vary widely depending on the industry and business model. Knowing your CLV equips you to make smarter decisions about marketing budgets, customer acquisition, and even inventory planning.

There are two main ways to calculate CLV:

• Historical Method: Add up all past purchases for an existing customer relationship.

• Predictive Method: Estimate future revenue by multiplying the average order value by the predicted number of orders.

CLV also helps you refine customer personas, making it easier to target the right audience.

Ways to Increase CLV

Here are three proven strategies to grow your CLV:

• Introduce a Loyalty Program: Businesses with loyalty programs often see an 80% positive ROI. These programs drive repeat purchases and keep customers engaged.

• Focus on Customer Experience: A better experience pays off - 86% of customers are willing to spend more for it. Investing in top-notch service can directly improve your CLV.

• Personalize Interactions: Use customer data to create tailored experiences. Research from Goethe University and the Wharton School shows that referred customers tend to have higher CLV and stronger loyalty.

"The advantage of determining customer lifetime value is not just the final number itself, but also the thinking and calculation behind the metric".

A high CLV indicates happy customers and a strong fit between your product and the market. It also allows you to outspend competitors on customer acquisition while staying profitable. Combining CLV with other retention metrics can help you fine-tune your strategy for both attracting and keeping customers.

2. Customer Churn Rate

Customer churn rate measures the percentage of customers a business loses over a specific time. Companies collectively lose $1.6 trillion annually due to churn, with 96% of unhappy customers staying silent and 91% never coming back. While Customer Lifetime Value (CLV) highlights profitability, churn rate pinpoints where retention strategies fall short.

How to Calculate Churn Rate

The formula depends on your business model:

• For Subscription-Based eCommerce:
  Churn Rate = (Starting Customers – Ending Customers + New Customers) / Starting Customers

• For Traditional eCommerce:
  

  Determine your average repeat purchase timeline. Then, track customers who haven’t made a repeat purchase within double that timeframe.

Example: A skincare brand with a three-month average repeat purchase cycle examined its January 2022 cohort of 1,000 customers. By July 2022, only 300 had made repeat purchases, revealing a 70% churn rate.

These calculations help you evaluate your performance against industry averages.

Industry Benchmarks

Once you've calculated your churn rate, compare it to these benchmarks for context:

Why Customers Leave

• 73% leave after multiple negative experiences

• 68% feel the company doesn't value them

• The average eCommerce churn rate ranges between 70% and 80%

Financial Impact of Reducing Churn

Lowering churn can significantly boost profits:

• A 5% increase in retention can lead to a 25% to 95% profit increase

• 65% of a company's revenue comes from existing customers

"Customer churn rate is a crucial metric that can shine a light on a company's shortcomings and reveal areas of improvement." – Kenza Moller, Contributing Writer

Practical Steps to Reduce Churn

• Offer Omnichannel Support: Make it easy for customers to contact you through their preferred channels.

• Collect Feedback: Use tools like CSAT and NPS surveys to identify issues early.

• Address Payment Failures: Automate systems to handle failed transactions and prevent involuntary churn.

• Enhance Post-Purchase Experience: Companies using Loop Returns report 15% fewer refunds compared to those that don’t.

• Personalize Communications: Segment customers by purchase history and engagement to deliver tailored messages.

Keep in mind that 80% of future revenue often comes from just 20% of your existing customers. Actively managing churn helps safeguard your most important resource: your customers.

3. Repeat Purchase Rate

Repeat purchase rate measures the percentage of customers who make another purchase within a specific timeframe. Research shows that customers making a second purchase often spend up to three times more than their initial order.

Understanding the Numbers

A good repeat purchase rate typically ranges between 20–40%. Shopify identifies 27% as a standard benchmark. Here's how repeat purchases often progress:

• 53% of customers return for a third purchase

• 64% continue to a fourth purchase

• 40% of revenue often comes from repeat customers

Calculating Repeat Purchase Rate

The formula is simple:
Repeat Purchase Rate = (Number of Repeat Customers ÷ Total Number of Customers) × 100

For example, if you have 26 customers and 18 of them return, your repeat purchase rate would be 69% (18 ÷ 26 × 100).

Real-World Success Stories

Companies that focus on improving repeat purchases have seen impressive results:

• Inkbox: Boosted repeat purchase rate by 80% in one month with their "Inkfam" points program.

• Jane Iredale: Increased repeat purchases by 40% through their "Beauty Rewards" VIP program.

• LIVELY: Achieved a 39% higher customer lifetime value and a 36% increase in spending using a loyalty program.

Strategies to Boost Repeat Purchases

• Smart Post-Purchase Communication
  

  Use targeted messaging to re-engage customers. For instance, Ruggable's "Rug Quiz" boosted purchase likelihood by 4x.

• AI-Powered Recommendations
  

  Leverage first-party data to provide personalized product suggestions based on customer behavior.

• Strengthen Loyalty Programs
  Example: Baby Tula's Collector's Club delivered impressive results:

  • 85,500 active members

  • 4.21 million points earned

  • 24% reward redemption rate

"Repeat purchases are compounding interest for monthly sales. The more you understand your repeat rate, the more you'll understand how fast you can grow." – Leo Strupczewski, April 28, 2021

Impact on Business Growth

• Loyal customers can be worth 10 times their initial purchase value.

• 89% of customers return after a positive service experience.

• Points-based loyalty programs deliver a 90% positive ROI.

Monitoring your repeat purchase rate provides valuable insights into customer behavior. These insights help refine your retention strategies, ensuring more frequent returns and long-term growth.

4. Average Order Value (AOV)

Average Order Value (AOV) is a key metric that focuses on how much customers spend per transaction. Unlike metrics tied to customer loyalty or repeat purchases, AOV zeroes in on revenue per order. This makes it a critical tool for boosting profitability without increasing customer acquisition costs.

Understanding AOV Benchmarks

Recent data from September 2023 highlights how AOV varies across industries:

Globally, the average eCommerce AOV surpassed $110 in September 2023. Interestingly, desktop users tend to spend 20% more per transaction than mobile users.

Calculating Your AOV

The formula to calculate AOV is simple:
AOV = Total Revenue ÷ Number of Orders

For instance, if your monthly revenue is $50,000 from 500 orders, your AOV would be $100.

Strategies to Boost AOV

• Free Shipping Thresholds
  

  A UPS survey found that 52% of shoppers add items to their cart to qualify for free shipping. Setting a free shipping threshold about 30% higher than your current AOV can encourage customers to spend more.

• Loyalty Programs
  

  Loyalty programs can increase AOV by an average of 13.71%. Additionally, 43% of customers are willing to spend more with brands they feel loyal to.

• Dynamic Pricing and Personalization
  

  Using dynamic pricing and personalized offers has been shown to raise AOV by 15.81%.

The Role of Customer Experience

Providing excellent customer service can have a big impact on AOV. Customers are 88% more likely to return after a positive experience, and enhanced shopping experiences can lead to 31% higher spending.

"An increase in the average order value for an online retailer has a strong correlation to an increase in profit. When an ecommerce retailer can sell more on each order, that retailer tends to make more profit overall. Thus, online retailers that are able to increase average order value - AOV - should also become more profitable."
– Armando Roggio, Director of Marketing and Ecommerce at D&B Supply

Tips to Optimize AOV

• Create Bundles
  

  Group complementary products together to provide added value and encourage larger purchases.

• Personalized Recommendations
  

  Use customer data to suggest items based on their past purchases, browsing habits, or preferences.

• Optimize for Desktop Users
  

  Since desktop users spend 20% more than mobile shoppers, ensure your desktop site is seamless while also improving mobile performance.

Watch Out for Common AOV Pitfalls

• Extreme order values (too high or too low) can distort your averages.

• AOV alone doesn’t account for profit margins.

• Seasonal trends may temporarily influence your numbers.

• Different product categories might require separate AOV tracking.

These insights and strategies can help you fine-tune your AOV and drive revenue growth.

5. Customer Retention Rate

Customer Retention Rate (CRR) measures the percentage of customers who stick with your brand and keep making purchases. Even a small boost in retention - just 5% - can increase profits by 25% to 95%.

Industry Benchmarks for Retention

Retention rates vary widely depending on the industry. Here's a quick look:

How to Calculate CRR

The formula for CRR is straightforward:
CRR = ((E – N) ÷ S) × 100

• E: Customers at the end of a period

• N: New customers during that period

• S: Customers at the start of the period

This calculation highlights gaps in your customer base and helps you focus on re-engaging those who may have drifted away.

Real-Life Examples of Retention Wins

Australian fashion retailer PAS Group increased retention from 48% to 69%, while Black Pepper went from 70% to 77%. They achieved this by targeting customers who had been inactive for 9, 18, or 36 months with specific campaigns.

Strategies That Work

Personalization and loyalty programs are powerful tools for boosting retention:

• The Honest Kitchen saw more referral opt-ins by offering tailored educational content.

• Nerdy Nuts improved retention by rewarding every online purchase.

"Start looking for clues in your data. Are people churning after one, three or six months? Do you understand why? Are you gathering customer insights that let you know why customers no longer use your product?" - Ian Rhodes, ECommerce Growth UK founder

Red Flags for Retention Issues

Watch out for these signs of trouble:

• Fewer repeat purchases

• Longer gaps between orders

• More customer complaints

• Lower engagement with marketing messages

• Declining loyalty program participation

Spotting these trends early can help you take action before the problem grows.

Measuring Success

Elph Ceramics combined data from online and physical stores using Shopify POS. The result? A 25% increase in their customer database and a 30% jump in retention.

Advanced Tactics to Drive Retention

Splash Wines introduced a subscription model during Black Friday and Cyber Monday, offering locked-in discounts for the holidays. This approach led to a 177% year-over-year increase in Cyber Weekend sales, with 40% of customers making repeat purchases.

"The most impactful retention strategies are built on shared data between a brand's tech stack, so your brand has a 360-degree view of every single customer - what they like, what they don't, when and what they purchase, who they are, and more." - Moran Khoubian, senior director, ecosystem & community at Yotpo

6. Net Promoter Score (NPS)

Net Promoter Score (NPS) measures customer satisfaction and predicts growth potential. Like CLV and churn, it provides a clear picture of customer loyalty - an essential factor for long-term success in eCommerce.

How NPS Works

To calculate NPS, subtract the percentage of detractors from the percentage of promoters. The result is a score ranging from –100 to +100. A positive score suggests you're doing well.

Industry Benchmarks

NPS averages vary across industries:

• Insurance: 71

• Ecommerce: 62

• Retail: 61

• Financial Services: 56

Why NPS Matters

NPS has a direct impact on business performance:

• Companies with high NPS grow at more than twice the rate of their competitors.

• Promoters are responsible for over 80% of referrals.

• Detractors contribute to more than 80% of negative word-of-mouth.

These findings highlight the importance of improving your NPS to drive growth and customer satisfaction.

Improving Your NPS

Here are some practical ways to boost your score:

• Website Experience

  • Ensure pages load within 3 seconds to avoid mobile drop-offs.

  • Simplify the checkout process - remove forced account creation.

  • Display security badges prominently to build trust.

• Customer Service

  • Add live chat for instant support.

  • Train your team to be both efficient and empathetic.

  • Act quickly on feedback from detractors.

"When you review your results, don't just look at the numbers. Review comments from customers, especially from your Detractors. In doing so, you'll often discover the small but significant flaws in your sales, payment, and order fulfillment processes that hurt the CX." – Retently

Success Story

LSKD, an Australian activewear company, shows how focusing on customer satisfaction pays off. By introducing SMS marketing, customer reviews, and a loyalty program, they achieved an 83% repeat purchase rate. Additionally, their customer lifetime value more than doubled for those redeeming loyalty rewards.

Advanced NPS Strategies

Take your NPS improvement efforts further with these advanced tactics:

• Personalization

  • 80% of shoppers prefer personalized experiences.

  • Send tailored email campaigns.

  • Provide product recommendations based on customer behavior.

• Feedback Loop

  • Use multiple channels to collect customer feedback.

  • Address issues immediately.

  • Set up alerts to identify and assist at-risk customers.

7. Customer Engagement Score

Tracking customer engagement adds depth to understanding how customers interact with your brand. The Customer Engagement Score (CES) measures activity across all touchpoints, offering insights into behavior and helping predict future actions. It's a key metric for driving eCommerce success.

Breaking Down CES

CES evaluates customer interactions by assigning weights to different activities:

Reading CES Scores

CES scores typically range from 1 to 100, indicating varying levels of engagement:

• 71–100: Highly engaged customers who are loyal and likely to make repeat purchases.

• 41–70: Moderately engaged customers who interact occasionally and use basic features.

• 1–40: Low engagement customers who are at risk of leaving and need immediate attention.

Why It Matters

Engaged customers contribute 23% more revenue, while personalized interactions lead to 48% more repeat purchases. On the flip side, disengaged customers can reduce revenue by 13%.

How to Track CES

Integrate CES tracking into your CRM to monitor engagement across channels. Calculate scores monthly and set up automated alerts for major shifts.

Ways to Improve Engagement

• Add interactive product tutorials.

• Send personalized emails.

• Launch a points-based loyalty program.

• Incorporate social proof elements like reviews and testimonials.

"Customer engagement -- which Gallup describes as a customer's emotional or psychological attachment to a brand, product, or company -- is the definitive predictor of business growth." – Gallup

Advanced Tactics

Segmenting Your Audience

Improving Engagement Channels

• Use dynamic product images and 360° views.

• Offer live chat support for instant help.

• Create interactive emails with polls or surveys.

• Send personalized push notifications.

Unlike one-time satisfaction metrics, CES focuses on continuous interactions, helping predict long-term customer loyalty.

Measuring Success

Keep an eye on these metrics to assess CES improvements:

• Rates of feature adoption.

• Time between customer interactions.

• Social media activity.

• Email open and response rates.

• Participation in feedback surveys.

Conclusion

Retention metrics are a game-changer for eCommerce growth and profitability. Boosting retention by just 5% can increase profits by 25–95%, and a staggering 41% of revenue often comes from only 8% of customers.

Here’s how these seven key metrics break down:

These aren’t just numbers on a dashboard - they’re tools for real results. For example, LSKD achieved an 83% repeat purchase rate, while Elph Ceramics increased retention by 30% through targeted engagement and loyalty strategies.

To make the most of these metrics, consider these three actionable strategies:

• Integration and Automation
  

  Use integrated tools to track metrics in real-time. This lets you react quickly to shifts in customer behavior and trends.
