Promoters minus detractors score. The Net Promoter Score (NPS) Calculator takes promoters (scored 9–10), passives (7–8), detractors (0–6) and returns net promoter score plus reading, responses, promoter share. Results update as you type, and the formula is shown under the result so you can repeat it in your own spreadsheet.
Marketing metrics are most useful as trends and comparisons between channels. Measure every campaign the same way, over the same period, and judge it against your gross margin rather than against revenue alone. Use the worked example below to check the maths against your own figures.
How the Net Promoter Score (NPS) Calculator works
NPS ranges from −100 to +100. Above 0 is acceptable, above 50 excellent, above 70 world-class. Track the trend and read the comments behind detractor scores.
Worked example
With the example values (promoters (scored 9–10) of 60, passives (7–8) of 25, detractors (0–6) of 15), the net promoter score is 45; reading Positive: more promoters than detractors, responses 100, promoter share 60%. Change any figure above and the result updates immediately; use Copy results to paste the summary into a note or email.
