What is a Net Promoter Score (NPS)?

Net Promoter Score (NPS) is a widely used customer loyalty metric that measures how likely your customers are to recommend your business, product, or service to others. It’s a simple but powerful way to gauge customer sentiment and predict growth.

Instead of asking about general satisfaction, NPS focuses on the likelihood of recommendation, which correlates strongly with retention, word-of-mouth referrals, and revenue growth.

How the NPS Calculator Works

This NPS calculator lets you compute your score instantly by analyzing customer responses on a 0–10 scale.

NPS Formula

NPS = % Promoters − % Detractors

Where:

• Promoters: Scores 9–10 → loyal enthusiasts
• Passives: Scores 7–8 → satisfied but unenthusiastic
• Detractors: Scores 0–6 → unhappy customers who can damage growth

Example:

• Responses: 10, 9, 7, 6, 5, 10, 8
• Promoters: 10, 9, 10 → 3/7 = 43%
• Passives: 7, 8 → 2/7 = 29%
• Detractors: 6, 5 → 2/7 = 29%

NPS = 43% − 29% = 14

Your score ranges from -100 to +100, with higher values indicating stronger loyalty.

How to Collect NPS Responses

Before using the calculator, gather responses using an NPS question. You can learn more about creating NPS questions with our NPS question type guide.

Typical NPS Question:

“On a scale of 0–10, how likely are you to recommend our product to a friend or colleague?”

Responses are then categorized into Promoters, Passives, and Detractors for calculation.
