Customer Satisfaction Score (CSAT)

Definition

Customer Satisfaction Score (CSAT)Customer Satisfaction Score (CSAT) measures how satisfied customers are with a specific product, service, or interaction. Respondents rate satisfaction on a short scale — typically 1 to 5 — and CSAT is the percentage giving the top one or two ratings. It captures short-term, transaction-level sentiment.

CSAT is the simplest and most direct customer-experience metric: ask people how satisfied they were, right after an interaction, and report the share who answered positively. Because it is transactional — tied to a specific ticket, purchase, or call — it is the fastest way to see whether a particular process or team is doing right by customers.

That simplicity is also its limit. CSAT captures momentary satisfaction, not long-term loyalty, which is why support teams usually track it alongside longer-horizon metrics like Net Promoter Score and operational ones like First Call Resolution.

How It Is Calculated

Benchmarks

Benchmark ranges below are industry references, not statutory rules — they vary widely by sector and by how each firm measures. Use them as directional context, not a target guaranteed to fit your business.

  • Many contact centers target roughly 75–85% top-box CSAT, though a "good" score depends heavily on industry
  • For a broad economy-wide benchmark, the ACSI national index stood at 76.9 out of 100 in Q4 2025 (a modeled 0–100 measure, not the same as a top-box CSAT percentage)
  • The ACSI has been roughly flat since 2017, easing about 0.5% year over year into Q4 2025

Key Points

  • The American Customer Satisfaction Index national score was 76.9 out of 100 in Q4 2025 and has not materially risen since 2017. (ACSI — National Q4 2025, Q4 2025)
  • ACSI uses a modeled 0–100 scale built from roughly 200,000 customer interviews a year — a different measure from the simpler top-box CSAT percentage most contact centers report. (ACSI, Q4 2025)
  • CSAT is a transactional metric, usually surveyed immediately after an interaction, reporting the share of respondents who chose the top one or two satisfaction ratings (top-box / top-2-box).
  • CSAT scales vary (1–3, 1–5, 1–7, 1–10); the 5-point scale is most common, with ratings of 4–5 counted as "satisfied."

CSAT, NPS, and First Call Resolution form the standard support-quality triad, and outsourced-support contracts often bake CSAT targets into the service-level agreement. When you hire customer support agents — in-house or via a BPO — CSAT is usually the headline number you manage them against.

FAQ

How is CSAT calculated?
CSAT (%) = (satisfied responses ÷ total responses) × 100. On a 1–5 scale, 'satisfied' usually means ratings of 4 or 5 (top-2-box). A CSAT of 80% means 80% of respondents rated their experience positively.
What is a good CSAT score?
Many contact centers target roughly 75–85% top-box, though "good" depends heavily on industry. For a broader economy-wide reference, the ACSI national index stood at 76.9 out of 100 in Q4 2025.
What is the difference between CSAT and ACSI?
CSAT is a simple top-box percentage from a post-interaction survey. The ACSI is a modeled 0–100 index built from about 200,000 interviews across the US economy each year. They use different scales and are not directly comparable.
How is CSAT measured?
Typically with a one-question survey sent right after an interaction — 'How satisfied were you?' — on a 1–5 or 1–10 scale. The share of respondents giving the top ratings becomes the CSAT percentage.
What is the difference between CSAT and NPS?
CSAT measures short-term satisfaction with a specific interaction or product, while NPS measures longer-term loyalty and willingness to recommend the brand overall. Many teams track both alongside first call resolution.
