Customer Satisfaction Metrics: 4 Key Measures to Track

A best practice among leading companies is to use a few focused metrics together, as no individual measurement can provide a complete picture on its own. The goal of your metrics is to help your leadership predict future business needs and make adjustments to operations that can lead to lasting improvements in customer satisfaction, relationships, and revenue growth. Here are four key metrics that have stood the test of time and remain effective measures of customer satisfaction.

These important customer satisfaction metrics are essential for enabling businesses to make data-driven decisions, improve customer experiences, and drive business growth.

By tracking these important customer satisfaction metrics, businesses are enabled to make informed decisions that enhance customer loyalty and overall satisfaction.

Introduction to Customer Satisfaction

Customer satisfaction is at the heart of every successful business. It reflects how well your company is meeting customer expectations and delivering on promises throughout the customer journey. Measuring customer satisfaction is essential for understanding what your customers value, where you excel, and where there's room for improvement.

Key customer satisfaction metrics—such as Customer Satisfaction Score (CSAT), Net Promoter Score (NPS), and Customer Effort Score (CES)—offer valuable insights into the customer experience. These satisfaction metrics help you gauge customer sentiment, track changes over time, and identify trends that impact customer loyalty and business growth. By regularly monitoring these key customer satisfaction metrics, businesses can make informed decisions to improve customer satisfaction, enhance customer loyalty, and drive sustainable business growth. Whether you're aiming to boost your customer satisfaction score CSAT, reduce friction with a lower customer effort score CES, or increase your net promoter score NPS, focusing on these metrics enables you to deliver experiences that consistently meet or exceed customer expectations.


Customer Satisfaction Metrics Comparison

Here's a quick comparison of the four key customer satisfaction metrics to help you understand when to use each one:

Metric What It Measures How to Calculate Good Score When to Use
NPS (Net Promoter Score) Customer loyalty and likelihood to recommend % Promoters - % Detractors 50+ is excellent, 30-40 is average, 0+ is good Measure overall brand sentiment and customer loyalty
CSAT (Customer Satisfaction Score) Satisfaction with a specific interaction or product and overall satisfaction (Sum of scores ÷ Total responses) × 100 75-85% is good, 85%+ is excellent Collect real-time feedback after support interactions
CES (Customer Effort Score) Ease of completing a specific task or interaction Average score on 1-7 scale (lower is better) Below 3 is excellent, 3-4 is good Identify friction points in customer journey
CAC (Customer Acquisition Cost) Cost efficiency of acquiring new customers Total marketing costs ÷ New customers acquired Varies by industry; should be < Customer Lifetime Value Evaluate marketing ROI and optimize spending

1. Net Promoter Score (NPS)

The Net Promoter Score is a complex metric that presents a lot more information about your brand. The NPS was first introduced in a 2003 article by Fredrick F. Reichheld in Harvard Business Review after two years of research on customer loyalty. It remains an important metric for any organization serious about customer engagement as it captures the overall sentiment a customer has based on their interaction with a brand. NPS is a key tool for measuring customer loyalty.

The NPS asks customers to answer a single question: "How likely are you to recommend [this company] to a friend or family member?" Customers rate this question with a score of 1-10, with 0 being never likely to 10 being definitely likely. Based on the ratings, customers are divided into three categories:

  • Promoters (9-10) – These are your most loyal customers who are very likely to purchase more from your brand in the future and become repeat customers.
  • Passives (7-8) – A difficult group to influence, these customers are generally satisfied by your product or service but are unlikely to remain loyal in the face of reasonable competition.
  • Detractors (0-6) – At best, this group can be considered indifferent, and, at lower scores, these customers are highly dissatisfied. Low scores are a sign of customer dissatisfaction and can indicate issues affecting customer retention.

To calculate the actual NPS, you take the percentage of Promoters from your overall survey pool and subtract the percentage of Detractors. This calculation provides a score that ranges from -100 to +100. A positive score is considered good, anything over 50 is excellent, and a negative score means that significant improvement is needed. Most industries have an average score of around 30-40.

2. Customer Satisfaction Score (CSAT)

The Customer Satisfaction Score gives you an indication of how satisfied a customer is with your product or service offering. It is measured by asking the customer to rate their satisfaction on a scale of 1-5, with 1 being very unsatisfied and 5 being very satisfied. CSAT surveys provide valuable customer satisfaction feedback that can be analyzed to identify trends and drive improvements in your service.

This metric is especially useful because it can be easily presented at the end of a customer service interaction and gives you real-time feedback about your performance. The customer service team plays a crucial role in delivering high CSAT scores and improving overall service quality. Reviewing these results over time can highlight trends in your ability to improve service, and it provides a simple and direct baseline metric for your service organization. Along with other customer satisfaction metrics, monitoring how CSAT scores change over time can reveal the impact of new customer service tools or processes. For example, you might find that CSAT scores improve after implementing a solution such as a shared inbox to ensure that no customer service inquiries fall through the cracks.

3. Customer Effort Score (CES)

Customer Effort Score gives you a measurement of your customer's effort required to interact with your business. The metric is typically collected by asking customers a single question that asks them how difficult it is to perform a specific action. Some examples include the ease of leaving a review, making a purchase, or contacting the customer support staff. CES is often measured after interactions with the customer support team to assess how easy it was for customers to get their issues resolved.

Like the CSAT, it is usually asked right after a service call or visit to collect a timely and accurate measurement based on the customer's experience. The primary benefit of the CES is the very focused nature of the question. It gives your team direct information about a particular aspect of your customer experience process that may need improvement. Analyzing CES results can help identify areas where service quality can be improved, ensuring your support processes meet customer expectations.

4. Customer Acquisition Cost (CAC)

Customer Acquisition Cost is an important metric that has become especially relevant in today's digital environment that enables highly targeted advertising. It's used by companies and their investors to understand how profitable a company's marketing efforts are and what may be done to improve them. Optimizing CAC allows businesses to attract more customers efficiently. To measure CAC, you divide a company's marketing costs during a time frame by the number of new customers acquired during that same period.

It's important to audit the data to understand any factors that affect the results, such as significant or long-term investments in marketing infrastructure or campaigns. Tracking your CAC metric over time will allow you to focus on improving your conversion metrics, measure the effects of any improvements to customer experience, and measure the impacts of major system improvements such as implementing a customer portal or knowledge base software.

It can be challenging to understand a customer's journey with your brand from end to end. As mentioned above, the best strategy for measurement is a holistic approach. By evaluating multiple points along your customer experience journey, you can make more informed business decisions and, most importantly, understand the effectiveness of any changes you are making as your business develops. While acquiring new customers is important, retaining existing customers is often more cost-effective and can lead to greater long-term value for your business.

Customer Feedback and Lifetime Value

Listening to your customers is one of the most effective ways to improve customer satisfaction and drive long-term business success. Collecting customer feedback through customer satisfaction surveys allows you to understand customer needs, preferences, and pain points directly from the source. This feedback is invaluable for identifying opportunities to enhance your products, services, and support processes.

Another important metric to consider is Customer Lifetime Value (CLV), which measures the total revenue a business can expect from a single customer over the course of their relationship. Satisfied customers are more likely to become loyal customers, leading to repeat business, positive reviews, and referrals. By consistently measuring customer satisfaction and acting on customer feedback, you can increase customer lifetime value, reduce customer churn rate, and build a base of loyal customers who contribute to your business's ongoing growth. Ultimately, prioritizing customer satisfaction and collecting customer feedback are key to understanding customer needs, fostering repeat business, and achieving lasting business success.


Customer Retention and Churn Rate

Customer retention is a critical indicator of your company's ability to keep customers engaged and satisfied over time. High customer retention rates are often a sign of strong customer satisfaction and effective customer support, while a high customer churn rate can signal underlying issues with your product, service, or customer experience.

To improve customer retention and reduce churn, it's essential to listen to customer feedback, understand customer expectations, and deliver experiences that consistently meet or exceed those expectations. Providing exceptional customer support, responding promptly to concerns, and personalizing your interactions can all help increase customer retention rate and decrease customer churn rate. By focusing on customer satisfaction and loyalty, businesses can foster long-term relationships, drive business growth, and create a loyal customer base that supports your brand through repeat purchases and referrals.


Customer Satisfaction Survey Best Practices

Customer satisfaction surveys are a powerful tool for collecting customer feedback and measuring key customer satisfaction metrics. To get the most out of your surveys, it's important to follow best practices that encourage participation and yield actionable insights.

Keep your surveys concise and focused, using clear and straightforward language that makes it easy for customers to respond. Ask relevant questions that directly measure satisfaction metrics such as CSAT, NPS, and CES. Consider using a mix of quantitative questions (like rating scales) and open-ended questions to gain valuable insights into customer experiences and preferences.

Regularly collecting customer feedback through well-designed surveys allows you to identify trends, uncover areas for improvement, and make targeted improvements that increase customer satisfaction. By analyzing survey data and acting on the results, you can build trust with your customers, demonstrate that you value their input, and foster greater loyalty over time.


How to Calculate Customer Satisfaction Metrics: Step-by-Step Examples

Calculating NPS (Net Promoter Score)

Example: You surveyed 200 customers and received these responses:

  • 100 customers rated 9-10 (Promoters) = 50%
  • 60 customers rated 7-8 (Passives) = 30%
  • 40 customers rated 0-6 (Detractors) = 20%

Formula: NPS = % Promoters - % Detractors

Calculation: 50% - 20% = 30 NPS

This score of 30 is considered average for most industries. Scores above 50 are excellent, while negative scores indicate serious issues. A high NPS score is a strong indicator of brand loyalty, showing that your customers are likely to return and recommend your business to others.

Calculating CSAT (Customer Satisfaction Score)

Example: After 100 support interactions, you received:

  • 5-star ratings: 60 responses
  • 4-star ratings: 25 responses
  • 3-star ratings: 10 responses
  • 2-star ratings: 3 responses
  • 1-star ratings: 2 responses

Formula: CSAT = (Number of satisfied customers ÷ Total responses) × 100

Typically, ratings of 4 and 5 are considered "satisfied."

Calculation: (60 + 25) ÷ 100 × 100 = 85% CSAT

A CSAT score of 85% is excellent, indicating strong customer satisfaction with your support interactions. A high CSAT score means you have a large number of happy customers who are satisfied with your support.

Calculating CES (Customer Effort Score)

Example: You asked 150 customers "How easy was it to resolve your issue?" on a scale of 1-7 (1 = very easy, 7 = very difficult):

  • Total score sum: 450 points
  • Total responses: 150

Formula: CES = Total score sum ÷ Total responses

Calculation: 450 ÷ 150 = 3.0 CES

A score of 3.0 is good. Lower scores (closer to 1) indicate less effort required, which correlates with higher customer loyalty and contributes to higher overall customer satisfaction by minimizing the effort customers need to resolve their issues.

Calculating CAC (Customer Acquisition Cost)

Example: Your SaaS company spent in Q1:

  • Paid advertising: $30,000
  • Marketing team salaries: $20,000
  • Marketing software tools: $5,000
  • Total marketing spend: $55,000

New customers acquired in Q1: 110 customers

Formula: CAC = Total marketing costs ÷ New customers acquired

Calculation: $55,000 ÷ 110 = $500 CAC

Whether this is good depends on your Customer Lifetime Value (LTV). A healthy ratio is LTV:CAC of 3:1 or higher. Understanding CAC in relation to Customer Lifetime Value also helps you identify and prioritize high value customers, allowing your business to focus on retaining your most profitable clients.

Industry Benchmarks for Customer Satisfaction Metrics

Understanding how your customer satisfaction levels compare to industry standards helps you set realistic goals and identify areas for improvement. Comparing your customer satisfaction levels to industry benchmarks is essential for accurately assessing your performance.

NPS Benchmarks by Industry

Financial Services 35-40 55+
Telecommunications 25-30 50+
Healthcare 30-35 55+
Insurance 30-35 50+

What is a good NPS? Any positive NPS (above 0) is good, 50+ is excellent, and 70+ is world-class.

CSAT Benchmarks by Industry

Industry Average CSAT Top Performers
SaaS/Software 78-85% 90%+
E-commerce 80-85% 90%+
Financial Services 75-80% 88%+
Customer Support 80-85% 92%+
Retail 75-80% 88%+

What is a good CSAT score? 75-85% is good, 85%+ is excellent, and 90%+ is exceptional.

CES Benchmarks

Since CES is typically measured on a 1-7 scale (lower is better):

  • Excellent: 1.0 - 2.5 (Very low effort)
  • Good: 2.5 - 3.5 (Low to moderate effort)
  • Needs Improvement: 3.5 - 5.0 (Moderate to high effort)
  • Critical: 5.0+ (Very high effort - risk of churn)

Industry insight: Research shows that 96% of customers who experience high-effort interactions become more disloyal, compared to only 9% who have low-effort experiences. High-effort interactions are a leading cause of poor customer experience, which can significantly increase customer dissatisfaction and disloyalty.

CAC Benchmarks by Industry

Industry Average CAC LTV:CAC Ratio
SaaS (B2B) $200-$500 3:1 to 5:1
SaaS (B2C) $50-$150 3:1 to 4:1
E-commerce $10-$50 3:1 to 5:1
Financial Services $200-$500 4:1 to 6:1

What is a good CAC? Your CAC should be at least 3x lower than your Customer Lifetime Value (LTV). A 3:1 LTV:CAC ratio is good, 4:1 or higher is excellent.
