Customer Satisfaction Rating (CSAT)

Customer satisfaction rating (CSAT) is a survey metric that captures how a buyer felt about a specific product, service, or interaction, scored on a fixed scale and reported as a percentage. A healthy CSAT sits between 75% and 80% across most industries.

Companies run CSAT because it tells them, in near real time, whether recent changes are landing. Add a new IVR flow, retrain the team, launch a feature, and the trend answers within a week.

The context around it keeps expanding. PwC’s 2024 Future of Customer Experience survey found 73% of buyers now rank experience above price, and McKinsey’s 2024 CX index put top-quartile firms at roughly 2× the revenue growth of laggards.

Key takeaways

• CSAT is a survey score, usually on a 1–5 or 1–10 scale, reported as the percentage of satisfied responses.
• Healthy scores sit between 75% and 80% for most industries; outliers above 90% often signal sampling bias, not excellence.
• CSAT measures a moment; NPS and CES measure loyalty and effort — the three run best together.
• Outsourced contact center teams usually own the CSAT number as a contractual SLA.
• Response rates below 10% distort the score; sample size and question wording matter more than most teams admit.

How it works

CSAT works by asking one direct question after a specific interaction: “How satisfied were you with…?” The customer picks a number on a fixed scale, most often 1 to 5.

Divide satisfied responses (usually 4 or 5) by total responses, then multiply by 100. The scale choice shifts what counts as satisfied:

Formula: (satisfied responses ÷ total responses) × 100. If 30 of 50 customers score 4 or 5 on a five-point scale, CSAT is 60%.

Simple by design. The discipline sits in when you ask, who you ask, and what you do with the answer. Post-call surveys sent within 15 minutes get roughly 2× the response rate of surveys sent the next day.

Response rate matters as much as the raw score. Below 10% and self-selection bias skews the result — usually toward happy or furious customers, with the quiet middle absent from the sample.

Examples

Strong CSAT programs pair one clear question with fast feedback loops. Four patterns show what works in the field, from retail to enterprise SaaS to outsourced support.

• Retail post-purchase: Uniqlo sends a 1–5 email survey 24 hours after checkout, targeting a 30% response rate on a single question.
• Contact center post-call: Optus in Australia triggers an SMS survey within 30 seconds of call end, weighted at 40% of agent scorecards.
• Enterprise SaaS relationship: Atlassian runs a quarterly relationship CSAT plus per-ticket CSAT, tracking both against renewal risk.
• Outsourced BPO: Manila-based providers commonly commit to a CSAT ≥80% SLA in business process outsourcing contracts, with financial penalties on misses.

The global backdrop matters. Precedence Research put the BPO market at USD 347.95 billion in 2025, growing at 10.05% CAGR through 2035. Every one of those seats is measured against a CSAT number somewhere.

Related terms

CSAT sits inside a family of customer-experience metrics. Each of the terms below measures a different slice of the relationship: the moment, the loyalty, the effort, or the outcome.

• Net promoter score: asks how likely a customer is to recommend you, measuring loyalty rather than one moment.
• Customer experience: the broader discipline that CSAT quantifies at a single touchpoint.
• First call resolution: the operational metric most tightly correlated with CSAT gains.
• Service level agreement: the contract that pins CSAT thresholds on outsourced teams.
• Call center: the operational unit whose calls generate most CSAT scores.
• BPO company: the provider running CSAT programs on the client’s behalf.

FAQ

What’s a good CSAT score?

Between 75% and 80% is healthy across most industries. Above 85% is strong. Above 90% is usually a red flag — either you’re surveying only the happiest customers, or the question is worded so no one dares click 3.

How is CSAT different from NPS?

CSAT rates one interaction (“How was that call?”), NPS rates the whole relationship (“Would you recommend us?”). CSAT moves week to week; NPS moves quarter to quarter. Most teams track both.

Do outsourced teams affect CSAT?

Yes, often more than any other single lever. Outsourced contact center teams handle the calls and chats that generate the score, and Philippine BPO contracts typically include CSAT floors of 80% with penalties below.

How often should we survey customers?

Post-interaction: within 15 minutes. Post-purchase: within 24 hours. Relationship-level: quarterly. Anything beyond that timing window drops response rates below 10% and the score stops being reliable.

Can CSAT be gamed?

Yes. Common tricks include agents asking for “a 5 out of 5”, surveys only sent to closed positive tickets, or leading question wording. Independent QA sampling and response-rate parity between agents catch most of it.
