DSAT (Dissatisfaction Score)

DSAT is the percentage of survey responses that land in the bottom box — typically the 1s and 2s on a 5-point scale — right after an interaction. It is the mirror image of CSAT, and people often compute it as "100 minus CSAT." That shortcut is wrong whenever the survey has a neutral middle: a 3 is neither satisfied nor dissatisfied, so it belongs to neither number. The honest version is the bottom-box count over total responses, measured on its own.

The reason to track it separately is that satisfaction and dissatisfaction are not two ends of one axis; they move for different reasons. A team can lift top-box CSAT with a delighted, vocal minority while the unhappy tail quietly thickens underneath — and the bottom box starts rising before the top box falls, which makes DSAT the earlier warning of the two. It also points at money: dissatisfied customers leave harder than satisfied ones stay, so the bottom box is a churn signal, not just a mood reading.

What it hides: DSAT inherits every sampling flaw CSAT has and adds a nastier one — the angriest customers frequently don't answer the survey at all, they just close the account. A low surveyed DSAT can mean a genuinely content base or a dissatisfied majority that skipped the form. It is also a small-numerator metric: on modest response volume, a handful of 1s swings it violently, so read it as a trend on adequate sample, never as a weekly scoreboard.
