Net Promoter Score (NPS) Calculation): A Quick Overview

To calculate your NPS score, whether by using an 11- point or 5-point NPS scale, all you need to do is,

STEP 1: Ask your customers how likely they are to recommend your product to others.

STEP 2: Then, categorize their responses into promoters (9-10), passives (7-8), and detractors (0-6).

STEP 3: Subtract % of detractors from % of promoters. This is the foundational NPS formula. Now, the NPS score can be anywhere between -100 and +100.

Now that you know your NPS Score, what is the next step? 

Is your NPS score good or bad? If it is 73, it is surely a good number. But what if your NPS score is 28? Is it bad? Not necessarily!

Assess the NPS score after Calculation: Methods

There are two methods to assess your NPS score right after its calculation:

1. Absolute Method: 

This method helps you to make your NPS score an internal benchmark. Any positive integer can be deemed to be a good NPS score since it indicates the overall positive sentiments of customers towards the business.

But to gain a competitive edge in customer experience, all your teams need to work fiercely to boost this number and compare it with the Industry Benchmarks. 

2. Relative Method:

This method helps you to understand where you stand against your competitors. Comparing your NPS Score with the Industry Benchmarks tells you how outstanding or poor your customer experience is against your competitors.

But, what is a bad NPS Score?

Let’s say you’ve got -25 after your NPS calculation. This is a negative NPS Score.

A negative NPS score means that you have more unhappy customers than those who enjoy your products or service. Simple!

Let’s take an example to explain such cases of the net promoter score.

Telecommunications giant Comcast has traditionally had poor NPS scores. It had a score of -3 in 2019. In fact, their customer service is considered so shoddy that they even had to promise US senators in 2016 that they would fix its service issues. Sadly, their NPS score is still negative.
