Find out which features your customers truly need, which ones delight them, and which ones they don’t care about, so you can build the right things first.
Kano Model Calculator
Formula
Must-be → Performance → Attractive
For each feature, you ask two questions: how customers feel if they have it, and how they feel if they don’t. The combination of their two answers places the feature into the Kano category.
What is a Kano Model Calculator?
A Kano Model calculator sorts your product features by how they affect customer satisfaction, using the model professor Noriaki Kano developed in 1984. Instead of ranking features on a single scale, it shows which ones customers expect and which ones win them over.
Must-be features
What do customers expect?
These are the basics customers simply expect to be there, like security or a checkout that works. Having them doesn’t impress anyone, but missing them upsets people fast. You have to get these right before anything else.
Performance features
What do customers want more of?
These are the more-is-better features. The better you do them, the happier the customers are, and the worse you do them, the less happy. Things like speed, price, and storage. This is usually what you compete with your rivals.
Attractive features
What delights customers?
The bonus features that surprise customers. Having them makes people happy, but leaving them out causes no complaints. They set you apart and can turn a good product into one people love.
Kano result
What does it tell you?
It shows you what to build first: cover every must-be, improve performance features that matter, and add a few delighters. It also spots the features customers don’t care about, so you can stop wasting effort on them.
From guesswork to features customers love
Build a roadmap around what customers actually value.
ProductBridge helps you collect feedback from across your channels, turn it into a clear roadmap, and share every release through a built-in changelog. The Kano model tells you which features matter most, and ProductBridge helps you gather that input and act on it.
How to Use Kano to Prioritize Features?
Pick the features you’re considering, then survey customers with two questions for each: how they’d feel with the feature, and how they’d feel without it. Their answers sort each feature into a category, showing you what to build first.
Use the results to prioritize in order: make sure every must-be is covered, invest in the performance features customers care about most, then add a few delighters to stand out. It’s also worth re-running the survey over time, because today’s delights slowly become tomorrow’s expectations for customers.

Kano Model calculator FAQ
Answers to common questions about using the Kano Model to categorize features, understand customer satisfaction, and prioritize product investments.
What are the five Kano model categories?
The full Kano model has five categories. Must-be features are the expected basics, performance features get better the more you invest in them, and attractive features delight customers. The last two are easy to forget: indifferent features leave customers unmoved no matter what you do, and reverse features actually annoy some customers when present. Most prioritization focuses on the first three, but checking for indifferent and reverse features is what stops you building things nobody wants.
Who created the Kano model?
The model was created by Noriaki Kano, a professor at the Tokyo University of Science, in 1984. His research showed that customer satisfaction isn’t one-dimensional — some features only prevent dissatisfaction, while others actively create delight — and the model has been a staple of quality management and product prioritization ever since.
How does the Kano survey work?
For every feature, a Kano survey examines customer reactions both with and without the feature. Customers answer on a five-point scale, from I like it to I dislike it. Their two answers are then matched on the Kano table, which sorts the feature into a category like must-be, performance, or attractive, showing how much it affects satisfaction.
When should you use the Kano model?
The Kano model works best when you have several possible features and need to decide which ones truly matter to customers. It’s especially useful before a big release, when planning a roadmap, or when your team can’t agree on what to build next. In short, reach for Kano when the stakes are high and customers' priorities aren’t clear.
How many responses do you need for a Kano survey?
There’s no fixed number, but you need enough responses to see a clear pattern for each feature. Small teams often start with 20 to 30 responses for a direction, while more confident teams usually need 100 or more. The right amount depends on how many features you’re testing and how varied your customers are.
What are the limitations of the Kano model?
Kano only tells you how customers feel about a feature, not how much time, money, or effort it takes to build, so it can point you toward features that aren't worth the cost. The answers are also subjective and can shift depending on someone's mood or how a question is worded. On top of that, categories don't stay fixed; today's delighters become tomorrow's expectations, so results can go out of date.
