Overview

CSAT is the most direct measure of customer satisfaction. Unlike NPS, which asks about overall loyalty, CSAT targets a specific moment: a support call, a purchase, a delivery, an onboarding session. The question is simple and the timing is immediate, which makes it one of the most actionable CX metrics available.

The standard CSAT question is: "How satisfied were you with your experience today?" answered on a scale of 1 to 5.

Key Facts
  • Scale: 1 to 5
  • Satisfied threshold: Ratings of 4 or 5
  • Score format: Expressed as a percentage (0% to 100%)
  • Formula: (Satisfied responses / Total responses) × 100
  • Good score: Above 80% in most industries
  • Excellent score: Above 90%
  • Best used: Immediately after a specific interaction or touchpoint

The CSAT scale

1Very dissatisfied
2Dissatisfied
3Neutral
4Satisfied
5Very satisfied

Only customers who select 4 or 5 are counted as satisfied in the final score calculation. Responses of 1, 2, or 3 are treated as dissatisfied regardless of degree.

How is CSAT calculated?

CSAT Formula
CSAT % = (Number of satisfied responses) ÷ (Total responses) × 100
Satisfied responses = those who answered 4 or 5 on the 5-point scale

Example: If 420 out of 500 respondents rated 4 or 5, the CSAT score is 420 ÷ 500 × 100 = 84%.

What is a good CSAT score?

CSAT rangeGeneral interpretation
Below 60%Poor, significant dissatisfaction present
60% to 75%Average, room for meaningful improvement
75% to 85%Good, above average in most industries
85% to 90%Excellent, strong satisfaction levels
Above 90%World-class, very high customer satisfaction

CSAT benchmarks vary significantly by industry. A score of 75% may be strong in one sector and below average in another. Always compare against sector-specific averages rather than a universal standard.

When should you use CSAT?

CSAT works best as a post-interaction metric, measured immediately after a defined touchpoint while the experience is still fresh. Common use cases include:

  • After a support ticket is resolved
  • Following a live chat or phone call
  • After product delivery or installation
  • At the end of an onboarding process
  • After a service appointment or in-branch visit
  • Following a product return or complaint resolution

CSAT is less suitable as a long-term relationship metric. For overall loyalty tracking, NPS is more appropriate.

How does CSAT differ from NPS and CES?

CSAT, NPS, and CES each measure a different dimension of customer experience. Using all three together gives a more complete picture than any single metric alone.

How does CSAT compare to oCX?

CSAT depends on customers responding to a post-interaction survey, which typically captures only 10 to 30% of the people who experienced the interaction. The silent majority never gets counted. Observational Customer Experience (oCX), developed by Alterna CX, measures satisfaction using all available customer signals including online reviews, social media posts, and contact center transcripts, without requiring a survey response.

This means oCX captures feedback from customers who would never fill out a CSAT survey, giving a broader and more representative picture of how customers actually feel across every touchpoint. Learn more about oCX and how it complements CSAT in a complete CX measurement program.

What are the limitations of CSAT?

  • Recency bias: scores reflect how the customer feels at that moment, which may not represent their overall relationship with the brand
  • Low response rates: post-interaction surveys often see response rates of 10 to 30%, leaving most feedback uncaptured
  • No root cause: CSAT tells you a customer was dissatisfied but not why without an open-text follow-up question
  • Scale interpretation varies: some customers always give the highest score regardless of experience; others rarely give a 5
  • Short-term view: a good CSAT score after one interaction does not guarantee long-term loyalty or retention

Key takeaway: CSAT is the clearest measure of how a specific interaction landed with a customer. It is most powerful when combined with an open-text question that explains the rating, and when trends are tracked over time rather than read as single data points.

Frequently Asked Questions

What is CSAT?
CSAT (Customer Satisfaction Score) is a metric that measures how satisfied customers are with a specific interaction, product, or service. It is typically collected via a short survey immediately after a touchpoint, asking customers to rate their satisfaction on a scale of 1 to 5. Only customers who rate 4 or 5 are counted as satisfied in the final score, which is expressed as a percentage.
How is CSAT calculated?
CSAT is calculated by dividing the number of satisfied customers (those who rated 4 or 5 on a 5-point scale) by the total number of survey responses, then multiplying by 100. The result is expressed as a percentage. For example, if 420 out of 500 respondents rated 4 or 5, the CSAT score is 84%.
What is the difference between CSAT and NPS?
CSAT measures satisfaction with a specific interaction at a specific moment, making it a transactional and short-term metric. NPS measures overall loyalty and the likelihood of recommending the company, making it a relational and long-term metric. CSAT is best used immediately after a touchpoint like a support call or delivery. NPS is better suited for periodic relationship health checks and competitive benchmarking.
What is a good CSAT score?
CSAT scores above 80% are generally considered good. Scores above 90% are considered excellent. Benchmarks vary significantly by industry, so it is important to compare against sector-specific averages rather than a universal standard. A score of 75% may be strong in one sector and below average in another.
When should you use CSAT?
CSAT works best as a post-interaction metric, collected immediately after a defined touchpoint while the experience is still fresh. Common use cases include after a support ticket is resolved, following a live chat or phone call, after product delivery or installation, at the end of an onboarding process, and after a complaint resolution. CSAT is less suitable as a long-term relationship metric. For overall loyalty tracking, NPS is more appropriate.
What are the limitations of CSAT?
CSAT has several limitations. Scores reflect how a customer feels at a specific moment, which may not represent their overall relationship with the brand. Response rates are typically 10 to 30%, leaving most feedback uncaptured. CSAT also tells you a customer was dissatisfied but not why, unless paired with an open-text follow-up. Scale interpretation varies across customers and cultures, and a good CSAT score after one interaction does not guarantee long-term loyalty.
How does CSAT compare to oCX?
CSAT relies on customers actively responding to a post-interaction survey, which typically captures only 10 to 30% of the customer base. Observational Customer Experience (oCX), developed by Alterna CX, measures satisfaction using all available customer feedback including online reviews, social media, and contact center data, without requiring a survey response. This means oCX provides a broader and more representative view of customer sentiment, covering customers who would never fill out a CSAT survey.
