Net Sentiment Score (NSS) is a CX metric used to measure the overall emotional tone of customer feedback. It reflects the balance between positive and negative sentiments expressed in comments, reviews, or survey responses.
NSS is used to monitor brand perception, identify emerging issues, and evaluate the emotional impact of customer experience initiatives in real time.
To calculate NSS, subtract the number of negative mentions from positive ones, divide by the total number of mentions, and multiply by 100:
((Positive – Negative) / Total Mentions) × 100
The score ranges from -100 (all negative) to +100 (all positive). A score above +40 is typically considered strong, while scores near zero or negative may indicate reputational concerns.
