Net Promoter Score (NPS) is a widely used metric that measures customer loyalty and satisfaction. Developed by Fred Reichheld, Bain & Company, and Satmetrix in 2003, NPS has become a standard in customer experience measurement across various industries, including SaaS.
The NPS is based on a single question: "On a scale of 0-10, how likely are you to recommend our product/service to a friend or colleague?" This simple yet powerful question helps gauge customer sentiment and predict business growth.
The NPS calculation process involves these steps:
Promoters (score 9-10): Loyal enthusiasts who will keep buying and refer others. Passives (score 7-8): Satisfied but unenthusiastic customers who are vulnerable to competitive offerings. Detractors (score 0-6): Unhappy customers who can damage your brand through negative word-of-mouth.
The formula is:

For example, if you have:
Your NPS would be: (60% - 10%) = 50
Determining a "good" NPS can be tricky as it varies by industry, company size, and geography. However, here are some general guidelines:
For SaaS companies specifically, the average NPS is around +30. Top-performing SaaS companies often score between +50 and +70. Comparing your NPS to benchmarks is just a starting point. The most valuable comparison is against your historical NPS scores, showing improvement over time.
For SaaS startups, NPS is crucial for several reasons:
NPS has been correlated with revenue growth. Promoters are more likely to renew subscriptions, upgrade plans, and recommend your product to others.
A low NPS can signal potential churn issues, allowing proactive measures to improve retention.
Feedback collected alongside the NPS question can provide insights for product improvements and new feature development.
NPS allows you to benchmark your customer satisfaction against competitors in your industry.
The simplicity of NPS makes it easy to implement and understand across your organization.
To effectively use NPS in your SaaS startup:
Conduct NPS surveys consistently, typically quarterly or bi-annually.
Include an open-ended follow-up question asking why the respondent gave that score.
Act on feedback, especially from Detractors.
Follow up with respondents to show you're listening and taking action.
Analyze NPS across different customer segments for granular insights.
Monitor how your NPS changes over time.
Share NPS results across the company to foster a customer-centric culture.
For SaaS startups, where customer retention and word-of-mouth referrals are crucial for growth, NPS can be a powerful tool for guiding strategic decisions and fostering a customer-centric culture.
While NPS shouldn't be the only metric you track, its simplicity, actionability, and proven correlation with business growth make it an essential component of any SaaS startup's toolkit.
