Customer Satisfaction Rating (CSAT)

Customer Satisfaction Rating (CSAT) is a survey metric that captures how a buyer felt about one 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 Interactive Voice Response (IVR) flow, retrain the team, ship a feature, and the trend answers you inside a week.

Other metrics ask about the whole relationship. CSAT answers a narrower question — did this one interaction land? That narrowness is the point, because it lets you tie a score to a queue, a script, a shift, or a single agent.

The context around the number keeps growing. PwC’s 2024 Future of Customer Experience survey found 73% of buyers now rank experience above price.

McKinsey’s 2024 customer experience index put top-quartile firms at roughly 2× the revenue growth of laggards. On outsourced accounts, the contact center team usually carries that target in its own scorecard.

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, while Net Promoter Score (NPS) and Customer Effort Score (CES) measure loyalty and effort. The three run best together.
• Outsourced teams usually own the CSAT number as a contractual threshold, with money attached to a miss.
• 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, then converting the answers into a percentage. Divide satisfied responses by total responses and multiply by 100. The scale you choose decides what counts as satisfied.

The question itself stays short: “How satisfied were you with the help you received today?” One question, one scale, no follow-up grid. Every extra field you add costs you responses, and responses are what make the score trustworthy.

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%, self-selection bias skews the result — usually toward happy or furious customers, with the quiet middle absent from the sample entirely.

A score with no action behind it decays into a vanity number. Strong programs route every 1 or 2 to a named owner, tag a reason code, and report the fix rate beside the score. Trend and cause travel together or neither means much.

Examples

Strong CSAT programs pair one clear question with a fast feedback loop. Five patterns show what works in the field, from retail checkout to enterprise software renewals to outsourced support floors in Manila and Cebu.

• 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 a text message survey within 30 seconds of call end, weighted at 40% of agent scorecards.
• Enterprise software relationship: Atlassian runs a quarterly relationship CSAT alongside per-ticket CSAT, tracking both against renewal risk.
• Outsourced delivery: Manila-based providers commonly commit to a CSAT floor of 80% or better in business process outsourcing (BPO) contracts, with financial penalties on misses.
• Self-service deflection: help articles ask for a single thumbs up or thumbs down at the foot of the page, so product teams see which article fails before support volume climbs.

The global backdrop matters. Precedence Research put the BPO market at USD 347.95 billion in 2025, growing at a 10.05% compound annual growth rate (CAGR) through 2035 — every one of those seats is measured against a CSAT number somewhere.

Read the patterns together and one thing stands out. The winners survey close to the event, keep the question to one line, and hand every low score to a person rather than a dashboard.

Related terms

CSAT sits inside a family of customer experience metrics, and the cluster below marks the boundaries. Each entry measures a different slice of the relationship: the moment, the loyalty, the effort, the operational cause, or the contract behind it.

• 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 onto 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

These are the questions buyers and providers ask most often about CSAT: what a healthy score looks like, how it differs from loyalty metrics, who owns the number on an outsourced account, and how often to survey.

What’s a good CSAT score?

Between 75% and 80% is healthy across most industries, and above 85% is strong. Above 90% is usually a red flag, because either you are surveying only your happiest customers or the question is worded so nobody dares click 3.

How is CSAT different from NPS?

CSAT rates one interaction (“How was that call?”) while NPS rates the whole relationship (“Would you recommend us?”). CSAT moves week to week and NPS moves quarter to quarter. Most teams track both and read them side by side.

Do outsourced teams affect CSAT?

Yes, and often more than any other lever, because outsourced teams handle the calls and chats that generate the score. Philippine BPO contracts typically include CSAT floors of 80% with penalties below. Governance stays with the client; daily control sits offshore.

How often should we survey customers?

Post-interaction surveys go out within 15 minutes, post-purchase within 24 hours, and relationship-level surveys quarterly. Stretch past that window and response rates fall below 10%, at which point the score stops telling you anything reliable.

Can CSAT be gamed?

Yes, and the usual tricks are agents asking for “a 5 out of 5”, surveys sent only to closed positive tickets, and leading question wording, all of which independent quality assurance sampling and response-rate parity checks between agents will catch.
