Imagine your friend calling you and asking for a suggestion about a grocery shop, and you can remember that you’ve just had a great shopping trip at a grocery shop with friendly staff, unique products, and prices.
Now you leave thinking, “I should tell my friends about this place.” That feeling is what the Net Promoter Score (NPS) captures and how likely customers are to recommend a brand to others.
In this post, we’ll explore what NPS is, why it matters, and how brands like Trader Joe’s use it to build lasting customer relationships.
What is NPS?
Net Promoter Score (NPS) is one of the most common ways to measure customer loyalty and satisfaction. It’s used by companies in various industries—like the grocery industry—to get a quick sense of how people feel about their experience.
This methodology is based on a simple question:
“On a scale of 0–10, how likely are you to recommend our company to a friend or colleague?”
Based on their answers, customers are grouped into three categories:
- Promoters (9–10): These loyal customers will recommend you to others.
- Passives (7–8): These customers are satisfied but uninterested in recommending you.
- Detractors (0–6): These unhappy customers might spread negative feedback.
Once you have classified your respondents into the three categories above, it is time to calculate your NPS using a simple formula:
NPS = % of Promoters – % of Detractors
That’s it! If you followed the steps correctly, you’ll get a percentage that reflects your customers’ satisfaction. A high NPS indicates that the customers are happy and loyal, while a low NPS indicates there may be issues to address.
How do I know if I have a good NPS? Well… the answer is simple: you need a benchmark in your industry to compare yourself. You can usually consider the average score for your entire industry or compare yourself to a direct competitor or a benchmark within your industry. Below, we’ll explore this a little more, using Trader Joe’s NPS as an example.

Trader Joe’s Customer Testimonials
Customer reviews help explain why Trader Joe’s earns such a high NPS:
“I love Trader Joe’s. They have great products at reasonable prices. I have a list of items from Trader Joe’s that I use daily. We go there about once a month. I wish they had a location more convenient to our home, then I might go there weekly. I hope they continue maintaining the same quality in all their products because I’ll always be a loyal customer!”
“I really like the products and private label offerings. It’s nice to know my $ are going to food quality vs. Facebook ads. The service is great.”
“Great quality food at reasonable prices. I am new to Trader Joe’s but blown away by the quality of the produce and products there. After decades of shopping at Safeway, I was shocked to find bananas for 23c/lb at Trader Joe’s when the same brand of banana sells for 99c/lb at Safeway — that is four times the price! Most of my reviews are critical ones, so I am particularly happy to post this review in praise of Trader Joe’s, my new supermarket.”
