Dissatisfied Customer Score

— Definition —

DSAT (Dissatisfied Customer Score) measures the percentage of support interactions that resulted in a negative customer rating. It is the inverse of CSAT, but tracking it separately matters because dissatisfied customers represent active churn risk — not just a scoring gap. A 1- or 2-star rating after a support interaction is a customer telling you directly that something went wrong.

— Formula —

DSAT % = (Number of negative ratings ÷ Total ratings received) × 100

"Negative" typically means ratings of 1 or 2 out of 5. Note that DSAT % + CSAT % do not add to 100% unless you have no neutral (3-star) ratings — most teams have some in the middle.

— Common mistakes —
  • 1Waiting for a weekly or monthly report to review DSAT — these customers are churn risks right now.
  • 2Tracking only team-level DSAT — agent-level DSAT reveals coaching needs that team averages hide.
  • 3Dismissing low-volume DSAT spikes — even a 3-day spike matters if the customers involved are high-value accounts.
  • 4Not following up on DSAT conversations — a fast, personal response to a bad experience can turn a churner into a loyalist.
