Your customer service team solved a problem in 30 minutes. The customer is satisfied. But will they recommend you? Are they loyal?
Those are different questions. And they require different metrics.
NPS, CSAT, and CES all measure customer experience, but they're measuring different things. This guide explains what each one captures and when to use them.
The Quick Comparison
| Metric | Measures | Question | Best For | |--------|----------|----------|----------| | NPS | Loyalty and advocacy | "Would you recommend us to others?" | Long-term business growth | | CSAT | Satisfaction with experience | "How satisfied are you?" | Immediate feedback after interactions | | CES | Effort required | "How easy was this?" | Process optimization |
NPS: The Loyalty Metric
Net Promoter Score measures customer loyalty by asking a single question:
"How likely are you to recommend [company/product] to a friend or colleague on a scale of 0-10?"
Then categorize responses:
- 9-10: Promoters (loyal, will recommend)
- 7-8: Passives (satisfied, but not passionate)
- 0-6: Detractors (unhappy, might criticize)
Formula:
NPS = (% Promoters) - (% Detractors)
Scale: -100 to +100
Real Example
Survey 100 customers:
- 60 say 9-10 (promoters) = 60%
- 20 say 7-8 (passives) = 20%
- 20 say 0-6 (detractors) = 20%
NPS = 60% - 20% = 40
An NPS of 40 is considered good (above 0 is good, above 50 is excellent).
What NPS Reveals
High NPS (50+) means:
- Customers love your product
- Organic growth through referrals
- Long-term viability
- Resilience against competitors
Low NPS (below 0) means:
- Customers actively dislike you
- Negative word-of-mouth
- Churn risk
- Need major improvements
Why NPS Matters
NPS correlates with business growth. Companies with high NPS grow faster because customers do free marketing (word-of-mouth).
Industry NPS benchmarks: | Industry | Typical NPS | Excellent | |----------|-----------|-----------| | Software/SaaS | 30-50 | 60+ | | Retail | 20-40 | 50+ | | Financial Services | 30-50 | 60+ | | Hospitality | 40-60 | 70+ | | Telecom | 10-30 | 50+ |
Apple and Amazon have NPS scores above 70 (exceptional). Telecom and utilities typically score 20-30 (mediocre).
The Problem with NPS
NPS only asks one thing: loyalty. It doesn't capture:
- Why customers are loyal (or not)
- What specific aspects they like
- How to fix problems
A detractor scoring 2 and someone scoring 6 both count as "detractors" even though they're very different. And passives (7-8) are completely ignored in the calculation even though they're the majority of customers in many industries.
CSAT: The Satisfaction Metric
Customer Satisfaction measures how satisfied a customer is with a specific interaction or product.
The Question
"How satisfied are you with [specific product/service/interaction]?"
Typically on a 1-5 or 1-10 scale.
Formula:
CSAT = (% answering 4-5 on 5-point scale) × 100
Typical target: 80-90% satisfied
Real Example
After a support interaction:
- 50 customers rate: 5 (very satisfied)
- 20 customers rate: 4 (satisfied)
- 10 customers rate: 3 (neutral)
- 15 customers rate: 2 (dissatisfied)
- 5 customers rate: 1 (very dissatisfied)
CSAT = (50 + 20) ÷ 100 × 100 = 70% satisfied
A CSAT of 70% is decent but below typical targets (80-90%).
What CSAT Reveals
High CSAT (85%+) means:
- Customers are happy with that specific interaction
- Product quality is good
- Service is responsive
Low CSAT (below 70%) means:
- That specific product or service needs improvement
- Support quality is declining
- Customers found issues
Why CSAT Matters
CSAT is transactional. It tells you quickly whether a customer's experience with a specific thing was good.
Best use: After customer support interactions, after product purchases, after onboarding.
The Problem with CSAT
CSAT measures a moment in time, not loyalty. A customer might rate a support interaction as 5-star (very satisfied) but still leave your product next week because it doesn't meet their needs.
Also, CSAT is inflated. Most companies score 70-90% CSAT because the question is about a specific interaction ("Were you satisfied with this support call?"). Of course they were if the problem got solved. But does that mean they'll stay as customers long-term? Not necessarily.
CES: The Effort Metric
Customer Effort Score measures how much effort it took a customer to complete a task or resolve an issue.
The Question
"How easy was it to [complete task / resolve issue / get support]?"
Typically on a 1-7 scale (1 = very difficult, 7 = very easy).
Formula:
CES = Average score or % rating 6-7
Lower effort = better (aim for CES below 3.5/7 or 50%+ rating 6-7)
Real Example
After an onboarding experience, 100 customers rate ease:
- 40 rate: 7 (very easy)
- 30 rate: 6 (easy)
- 20 rate: 4 (neutral)
- 10 rate: 2 (very difficult)
CES (% rating 6-7) = (40 + 30) ÷ 100 × 100 = 70% rate it easy
Average CES = (40×7 + 30×6 + 20×4 + 10×2) ÷ 100 = 5.4/7
An average CES of 5.4 is good (above 5 is solid).
What CES Reveals
High CES (6+/7) means:
- Your process is smooth and frictionless
- Customers can self-serve easily
- Support tickets might be lower
- Onboarding is effective
Low CES (3-4/7) means:
- Your process is complicated
- Customers struggle
- Support burden is high
- Improvements needed
Why CES Matters
Research shows that customers with low effort are more likely to be loyal and less likely to churn. Reducing friction drives retention.
Use CES to optimize operations:
- How easy is onboarding?
- How easy is it to upgrade/change plans?
- How easy is checkout?
- How easy is support?
When to Use Each Metric
Use NPS When:
- Measuring overall brand health. Is your company one customers love?
- Tracking long-term trends. NPS should be improving year-over-year if you're improving.
- Comparing to competitors. "We have NPS 45, competitor has NPS 35" — clear competitive advantage.
- Planning strategic decisions. High NPS = you can invest in growth. Low NPS = you need to fix product/service first.
- Sales/marketing messaging. High NPS justifies word-of-mouth and referral-based marketing.
Frequency: Quarterly or annually. NPS shouldn't change dramatically month-to-month.
Use CSAT When:
- After support interactions. "Was your support experience good?"
- After purchase. "Are you satisfied with your order?"
- After feature release. "How satisfied are you with the new feature?"
- Quick feedback. CSAT is easy to collect and analyze.
Frequency: Continuously or weekly. Quick feedback loop.
Use CES When:
- Onboarding. "How easy was it to get started?"
- Checkout process. "How easy was checkout?"
- Support issue resolution. "How easy was it to resolve your issue?"
- Self-service features. "How easy was it to find what you needed?"
Frequency: Continuously. Immediate feedback after interactions.
The Ideal Framework: Use All Three
They measure different things:
NPS = "Do you love us?" (loyalty)
CSAT = "Were you satisfied?" (transaction quality)
CES = "Was it easy?" (friction/effort)
A strong customer experience requires all three.
Real Example: E-Commerce Company
NPS 35: Customers somewhat loyal, but not passionate advocates. CSAT 82%: Customers satisfied with shopping experience. CES 4.2/7: Checkout process is a bit clunky.
Interpretation: The company sells fine products (CSAT is decent), but the checkout process is friction-filled (low CES), and customers aren't passionate enough to recommend (NPS moderate). Action: Simplify checkout to reduce CES, which should improve NPS (easier path to purchase = happier customers).
Real Example: SaaS Company
NPS 62: Customers love the product and recommend it. CSAT 90%: Customers satisfied with product. CES 3.1/7: Onboarding is difficult.
Interpretation: Strong product (NPS and CSAT both high), but onboarding has friction (low CES). New customers struggle at the start, so some churn before seeing value. Action: Improve onboarding (guided tours, tutorials) to lower CES, which should reduce early churn and increase lifetime NPS retention.
Checklist: Measuring Correctly
- ✓ NPS is measured at least quarterly, tracked over time
- ✓ CSAT is measured after specific interactions, not once a year
- ✓ CES is measured at touchpoints where effort matters (onboarding, checkout, support)
- ✓ You're not relying on one metric alone
- ✓ You segment NPS/CSAT/CES by customer cohort or product to find patterns
- ✓ You're taking action based on scores (not just collecting data)
- ✓ You're comparing to industry benchmarks
The Bottom Line
NPS asks: Will customers become advocates? CSAT asks: Are customers satisfied with this specific thing? CES asks: Was it easy for them?
A great product has:
- High NPS (customers love it)
- High CSAT (transactions feel good)
- Low CES (easy to use and support)
Track all three. Use NPS for strategy, CSAT for feedback, CES for optimization. Together, they give you a complete picture of customer experience health.
