Vibe Coding for Product Development:

Unit Economics Calculator

At JetStyle, we are ambassadors of the product development approach.

Case Studies

With our experience of scaling products and consulting startups, we are certain that unit economics is the most effective method to find ways to maximize your profits.

Unit economics provides a formula – a pretty complicated one, but our custom-made Unit Economics Calculator helps to experiment with it easily. This tool helps you understand if you’re scaling profits or losses, and provides you with a list of metrics you need to keep track of.

Intro

We needed to rebuild our unit economics calculator to embed it on the new version of our website.

A traditional rebuild would mean involving developers, writing logic, testing, and spending weeks on a single page.

Instead, we treated it as an internal R&D experiment. Can a small team ship it in one day using AI as a development assistant?

JetStyle & AI
Challenge

1

Create a calculator that not only computes metrics but visually explains the formula and relationships between variables

2

Make it responsive and brand-aligned

3

Deliver fast, without launching a full development cycle

Solution
Design First

We started with a clear Figma layout and defined the structure before any code appeared.

AI-Assisted Build

The first working code draft was generated in 26 seconds.

From there, the designer iterated with AI, refining layout and responsiveness. The final production-ready version was ready within 8 hours = just one working day.

Result

We launched:

  • a fully functional unit economics calculator
  • instant input processing
  • responsive behavior
  • zero dedicated development cycle
More importantly, we validated a faster workflow:
Product Owner + Art Director + Designer + AI
= working product tool in one day.

What This Proves

For clearly scoped digital tools, like calculators, configurators, micro-utilities, AI can compress production time dramatically.

Your expertise matters: you still need to have a clear vision of what should come out as a result. But execution cycles become radically shorter.
