什么是客户保留率？完整指南

客户保留率是在特定时期内保持活跃或继续使用产品/服务的客户百分比，是业务健康状况和保留策略有效性的指标。

Sales and CRM

Customer retention rate is the percentage of customers who keep doing business with you over a given period. In subscription businesses it is the counterpart of churn. It shows how many customers you keep and build relationships with, rather than lose to competitors or churn. For digital marketers, it is key to sustainable growth and profitability.

Here's the challenge. In our experience at Arfadia, many companies underinvest in retention. They chase new acquisition tactics while existing customers quietly head for the door. According to Harvard Business Review, acquiring a new customer can cost five to 25 times more than retaining an existing one, yet DemandSage reports that only 18% of companies prioritize retention, while 44% focus primarily on acquisition.

How to Calculate Customer Retention Rate (a Formula That Really Works)

Let's cut to the chase. Here is the formula we use at Arfadia for all of our clients:

Customer Retention Rate = ((E - N) / S) x 100

Where:

S = Number of customers at the start of the period
E = Number of customers at the end of the period
N = New customers acquired during the period

Example: You start January with 1,000 customers (S), add 200 new customers (N) and end January with 1,050 customers (E). Your retention rate is ((1,050 - 200) / 1,000) x 100 = 85%.

The key point many marketers overlook: new customers must be excluded from this calculation. Otherwise you are measuring growth, not retention. We suggest calculating it monthly for subscription businesses and quarterly for traditional B2B services.

Why customer retention rate matters more than it ever did

The numbers make the case. Research by Frederick Reichheld of Bain & Company, cited by Harvard Business Review, found that increasing customer retention rates by 5% increases profits by 25% to 95%.

We have seen this across many client campaigns at Arfadia: companies that retain customers well tend to outperform their competitors on the metrics that matter. Here's why:

Retained customers spend more. DemandSage reports that existing customers spend 67% more than new customers, and that companies typically generate 65% of their revenue from repeat customers. Loyal customers aren't just sticking around; they are deepening their relationship with your brand.

Retention creates predictable revenue. Businesses that depend on constant acquisition ride a rollercoaster, while companies with strong retention can project revenue months ahead. That consistency supports smarter strategic decisions and more confident investment in growth.

Word of mouth becomes a growth engine. Customers who feel an emotional connection to a brand are more likely to stay, buy again and recommend it to others.

Customer Retention Rate benchmarks by Industry

Here is what good retention looks like across industries, based on our research and DemandSage's industry retention statistics. Across all industries, DemandSage puts the average customer retention rate at approximately 75.5%.

SaaS and Technology Companies

Benchmark: 91% median gross revenue retention

In SaaS, retention is usually measured in revenue as well as in customers. Gross revenue retention shows how much recurring revenue you keep from existing customers; net revenue retention adds expansion revenue such as upgrades and cross-sells.

ChurnZero's look at SaaS retention benchmarks, based on SaaS Capital's 2023 benchmarks for private B2B companies (data through 2022), reports a median gross revenue retention of 91% and a median net revenue retention of 102%. For companies with annual contract values above $250,000, median net revenue retention reached 110%.

E-commerce and Retail

Benchmark: 63% retention for retail

Retail sits near the bottom of DemandSage's industry table; only hospitality, travel and restaurants score lower, at 55%. Shoppers can compare and switch easily, so strong e-commerce brands win repeat purchases through convenience, personalization and service.

Subscription Services

Benchmark: compare against your own category and billing cycle

Churn varies by industry, price point and billing cycle, so compare your figures against benchmarks for your own category. Recurly, for example, publishes subscription churn benchmarks by industry.

Real-World Customer Retention Examples

Onboarding: Guiding New Users to Value

Many software products lose a large share of new users before those users see real value. A common fix is in-app guidance that walks users through key tasks across the product.

The lesson: early, positive customer success interventions make an outsized difference to long-term retention. Users who reach a first success quickly have a reason to come back.

Zappos: A Culture of Service Excellence

Zappos built its reputation on customer service. Its approach is service that turns transactions into relationships.

We encourage our clients to adopt a similar philosophy. The lesson: many customers will pay a premium for exceptional service, and relationships built on service tend to grow in value over time.

Netflix: Personalization at Scale

Netflix uses its recommendation system to help members find what to watch next, so engagement is driven by relevance. This retention-through-relevance approach is a model we use for data-led customer strategies.

"The companies that are truly winning in today's market aren't the ones with the flashiest acquisition tactics, they're the ones that have mastered the art of keeping customers engaged long after the initial purchase. We've seen clients increase their revenue substantially simply by shifting their focus from hunting new customers to nurturing existing relationships."

Here are 7 strategic advantages of focusing on Customer Retention

1. Dramatic Cost Efficiency Gains

Acquiring a new customer can cost five to 25 times more than retaining an existing one, according to Harvard Business Review, so retention gains can be worth pursuing. Shifting part of the budget from acquisition to retention can make your marketing spend go further, provided the retention work itself is cost-effective.

2. Compound Growth Acceleration

Forrester's 2024 US Customer Experience Index found that CX quality had fallen to an all-time low after declining for a third year in a row. In the same release, Forrester said customer-obsessed organizations reported 41% faster revenue growth, 49% faster profit growth and 51% better customer retention than organizations that are not customer-obsessed. That is an association, not proof that CX alone causes those results.

3. Predictable Revenue Forecasting

Companies with high retention can forecast revenue further ahead, while companies with weak retention often struggle to forecast even one quarter out.

4. Premium Pricing Power

High retention can give you more pricing flexibility, but it doesn't guarantee that you can raise prices without losing customers. Test how much extra value customers see and how price-sensitive they are before changing prices.

5. Natural Advocacy Development

Retained customers can be your most effective marketing channel. Loyal customers recommend you to others, so strong retention builds a base of brand advocates.

6. Competitive Differentiation

In crowded markets where products look alike, retention can be a lasting competitive advantage. While rivals chase the next customer, retention leaders nurture ongoing relationships.

7. Operational Excellence Catalyst

A focus on retention pushes a business to earn loyalty at every interaction, from onboarding and support to product development.

Tried and True Techniques to Increase Your Customer Retention Rate

How to Master the First 90 Days

4 Customer Retention Mistakes to Avoid

Mistake #1: Focusing Only on Acquisition

Despite the cost advantages and competitive leverage that retention offers, many companies still spend most of their marketing budget on acquisition and neglect the customers they already have.

Mistake #2: Making Cancellation Difficult

Complicated cancellation procedures lead to bad reviews and kill word of mouth. We believe in transparent, respectful offboarding that leaves the door open for customers to return.

Mistake #3: Providing the Same Service to Every Customer

Your highest-value customers warrant premium service, while more price-sensitive segments need different engagement approaches.

Mistake #4: Ignoring Early Churn Signals

Proactive outreach based on leading indicators can prevent churn before customers start thinking about leaving.

The Future of Customer Retention Is AI-Powered

AI is shifting retention from reactive to predictive. We use AI systems that analyze many behavioral signals to identify at-risk customers earlier.

Using machine learning, hyper-personalization lets brands tailor experiences to individual customers at scale. Pricing, content and the timing of communication can all adapt to what the models predict.

Conversational AI can offer round-the-clock support that helps retention. Unlike older rule-based chatbots, today's AI assistants can handle more complex questions and pass difficult cases to a person.

Customer Retention Rate FAQs

What is a good customer retention rate?

Benchmarks vary widely by industry. DemandSage puts the average across all industries at approximately 75.5%, ranging from 55% in hospitality, travel and restaurants to 84% in media and professional services. Compare yourself with your own industry and your own trend rather than with a single universal number.

How often should you calculate customer retention rate?

Fast-moving businesses usually measure it monthly, while many B2B services do well with a quarterly cycle. What matters most is the trend over time. Even if you calculate it less often, we suggest watching leading indicators every day.

What is the difference between retention rate and churn rate?

They are mathematical complements: retention measures the customers who stay, and churn measures those who leave. For the same group of customers and the same period, retention plus churn equals 100%. We focus on retention for positive framing but monitor both for a full picture.

How does customer retention rate affect lifetime value?

Higher retention lengthens the average customer lifetime, which raises lifetime value as long as those customers remain profitable. Be clear whether CLV is based on revenue or on contribution margin, and keep the time horizon and cost assumptions consistent. A longer relationship does not automatically mean more profit if a customer is costly to serve.

What are the key drivers of customer retention?

Product quality, customer support, pricing strategy, onboarding effectiveness and ongoing engagement all count. In our experience, setting accurate expectations during the sale and early customer success interventions have a disproportionate impact.

Can a customer retention rate be too high?

Generally, high retention is good news. Retention measures how many existing customers stay, not how many new customers you win, so a rate close to 100% says nothing on its own about growth. What matters more is whether the customers you keep are profitable and a good fit, and how much it costs to serve them.

How can you improve retention cost-effectively?

In some situations, personalization and automation can lower the cost of keeping each customer, although they bring their own setup and operating costs. Outreach's guide to customer retention strategies recommends monitoring customer activity and usage data to spot at-risk accounts early and give them extra support, which helps you focus limited resources where they matter most.

Related Customer Retention Metrics

Customer Lifetime Value (CLV)

Greater retention can raise CLV by lengthening the relationship and creating room for cross-selling. Whether that adds profit depends on the margin each customer generates and the cost of serving them over the same time horizon.

Net Promoter Score (NPS)

NPS is a leading indicator of loyalty: track it alongside retention, and treat a falling score as an early warning.

Customer Acquisition Cost (CAC)

We track the LTV:CAC ratio closely, and retention improvements are one of the fastest ways to improve it.

Monthly Recurring Revenue (MRR)

For subscription businesses, retention is the key to keeping MRR stable.

Churn Rate by Cohort

Don't wait until customers near the end of their average tenure. Cohort analysis shows when churn tends to happen, so you can reach out early to customers who are at risk.

How to take your customer retention to the next level

Customer retention rate isn't just another metric; it is a building block of profitable growth. Across many client engagements at Arfadia, we have seen how a focus on retention changes the whole company.

The math is clear. Reichheld's research found that a 5% increase in retention can lift profits by 25% to 95%, which makes retention one of the best investments a marketer can make.

Success needs a systematic approach that ties technology, strategy and culture together. Start by tracking your current retention rate with the formula above, benchmark it against your industry, and then apply the strategies covered here.

Most importantly, make retention everyone's job, not just a team KPI. The strongest companies focus on keeping customers, not just acquiring them. In a connected world, retention is reputation.
