I wanted a clean and simple EMI calculator for a small personal project,
So I decided to build one using plain HTML, CSS, and vanilla JavaScript.
No frameworks, no libraries — just the basics.
Features
- Calculates monthly EMI instantly
- Simple and clean UI
- Mobile responsive layout
- Built with HTML, CSS, and vanilla JS
Why I built it
Most EMI calculators online are overloaded with ads or unnecessary options.
I wanted something:
- Easy to understand
- Quick to use
- Reusable in other small projects
Implementation overview
- HTML handles the form structure and inputs
- CSS is used for layout, spacing, and responsiveness
- JavaScript handles:
- EMI formula calculation
- Input validation
- Updating results dynamically
Live demo & source code

What I learned
- Even small calculators benefit from good UX
- Clear labels and defaults reduce user friction
- Vanilla JavaScript is more than enough for focused tools
I’m building more small, practical web tools like this
to improve my front-end skills and share what I learn.
Feedback on the UI or logic is welcome.
