An illustrative reading on the scale this metric uses.

Definition

A customer loyalty metric that measures how likely customers are to recommend a company's product or service to others. It subtracts Detractors from Promoters.

A standardized customer satisfaction index calculated by asking customers how likely they are to recommend a company on a scale of 0 to 10, grouping responses into Promoters (9-10), Passives (7-8), and Detractors (0-6), and subtracting the percentage of Detractors from Promoters.

Why it matters

NPS is a key leading indicator of customer retention and growth. A high NPS shows strong loyalty, which translates into lower churn, more referrals, and more organic upsell opportunities, while a low NPS signals future customer loss.

Directly related: LTV, Retention, Upsell.

Formula

Promoters (%) - Detractors (%)

Improvement tips

  • Follow up with detractors immediately to resolve their issues and prevent negative word of mouth.
  • Ask a follow up open ended question to understand the reason behind the score.
  • Share NPS feedback across the engineering, product, and sales teams to align on improvements.

Common mistakes

  • Focusing only on the average score while ignoring the specific complaints from detractors.
  • Surveying customers too frequently, which leads to survey fatigue and low response rates.
  • Manipulating the timing of the survey to only ask customers when they are happy.

Frequently asked questions

Do I need to track NPS before I start my business?
No, you do not need to track NPS before launching because you do not have any customers yet. You should focus on building your product and closing your initial sales before setting up a formal loyalty survey.
When does NPS first become relevant for a new startup?
NPS becomes relevant once you have a steady group of active customers who have been using your product for at least a few weeks. Conducting surveys at this stage gives you your first real data on customer loyalty and product quality.
How often should a new company send out NPS surveys?
A new company should typically send NPS surveys once or twice a year to avoid survey fatigue. Sending surveys too frequently can annoy your customers and reduce the response rates of your surveys.
Should an aspiring founder use NPS as their main business metric?
No, NPS should not be your main metric when starting out because early revenue and product-market fit are far more critical. NPS is a useful health check, but it cannot replace tracking cash flow and customer acquisition.
Why does NPS matter for a business already running?
NPS matters because it serves as an early warning system for customer loyalty and future revenue drops. A low score highlights hidden issues in your product or service before customers start canceling their accounts.
What goes wrong when a business ignores its NPS feedback?
Ignoring NPS feedback allows customer complaints to go unresolved, leading to high churn rates and negative word of mouth. Neglecting feedback also prevents your team from knowing who your most loyal promoters are for referrals.
How do I start collecting NPS scores without stopping day-to-day operations?
You can automate the process by setting up a simple email survey tool that automatically emails customers a single loyalty question after their purchase. This automation allows you to collect scores in the background with zero daily effort.
What should I do if my business receives a very low NPS score?
If your score is low, you should contact the unhappy customers immediately to understand their complaints and resolve their issues. Use their feedback to make specific improvements to your product or service quality.
What does NPS actually mean in plain words?
NPS stands for Net Promoter Score and is a simple number that shows how happy and loyal your customers are. The score is based on asking them how likely they are to recommend your business to a friend.
Is setting up NPS complicated or expensive?
No, setting up NPS is very simple and can be done for free using standard online form tools. You only need to ask one question on a scale of zero to ten to calculate your score.
Do I need a customer success team to handle NPS?
No, you do not need a customer success team to manage NPS when you have a small business. A business owner can easily send the surveys and review the responses themselves.
How is the NPS score calculated?
The score is calculated by taking the percentage of customers who score you a nine or ten and subtracting the percentage who score you a six or lower. The final number ranges from minus one hundred to plus one hundred.
