Customer Satisfaction Score (CSAT)

Customer Satisfaction Score (CSAT)

Customer Satisfaction Score (CSAT) is one of the simplest and most widely used metrics for understanding how customers feel about a specific interaction. Whether after a phone call, live chat, or email resolution, CSAT surveys offer a direct pulse on customer sentiment — fast.

Despite its simplicity, CSAT is often misused, misinterpreted, or over-weighted in operational decision-making. In the spirit of VitalogyCX, we aim to recalibrate how CSAT should be measured, interpreted, and acted on — with context, signal sensitivity, and system-wide awareness.

What is CSAT?

CSAT measures the percentage of customers who are satisfied with a specific service interaction. Typically, it’s asked via a quick post-interaction survey:

“How satisfied were you with your experience?”

Responses are usually captured on a 1–5 or 1–10 scale, with only the top tiers (e.g., 4–5 or 9–10) counted as “satisfied.”

Formula

If using a 1–5 scale and counting 4 and 5 as “satisfied”:

CSAT (%) = (Number of satisfied responses / Total responses) × 100

For example, if 75 out of 100 respondents chose 4 or 5:

CSAT = (75 / 100) × 100 = 75%

Why CSAT Matters

  • Fast Feedback Loop: CSAT provides near-immediate insight into how a customer felt right after the experience.
  • Agent Coaching: When tied to specific agents or teams, it offers a directional input for coaching — but only if paired with context.
  • Process Clarity: CSAT drops often indicate process friction — long hold times, unclear answers, poor transitions — rather than agent failure.

Vitalogy Red Flags

1. No Context = Misleading Metric

Was the customer satisfied with the resolution, the wait time, or the tone of the rep? CSAT doesn’t tell you. That’s why context is the compass. Pair CSAT with metadata like handle time, silence ratios, or escalation tags to interpret it correctly.

2. Channel Blindness

CSAT norms differ drastically by channel. A 90% CSAT on email isn’t equivalent to 90% on phone. Calibrate your expectations to the conversational medium, not just the number.

3. Bias in Who Responds

Only a small slice of customers respond to CSAT surveys — and they tend to be either thrilled or furious. Don’t treat it as a statistically complete representation. Vitalogy recommends comparing CSAT patterns to non-survey signals like sentiment trajectory or resolution confidence to balance the picture.

Design CSAT for Action

Don’t just dashboard it. Route low scores to QA. Trigger coaching workflows. Automatically tag transcripts with follow-up reasons when CSAT is low. This is what design for action looks like — turning passive feedback into active system improvement.
