I will build a custom interactive HTML calculator or web tool
Halil T.
About this gig
Build a custom interactive HTML calculator or web tool with clean dark design, real-time calculations, and zero dependencies. Every tool is delivered as a single HTML file no frameworks to install, no hosting required, just open and use.
I build calculators for mortgage, ROI, calorie, savings, and any custom logic you need. Beyond calculators, I also build interactive ebooks, dashboards, landing pages, quizzes, and lead capture forms all as single embeddable HTML files.
What you get: a fully functional tool with instant client-side calculations, mobile responsive layout, professional dark and gold design, and a clean codebase you can embed anywhere or share as a direct link.
Message me before ordering if your tool has specific logic or multiple calculation types so I can recommend the right package.

Interactive tools and data-driven digital products — built to actually work, not just look good.
I design interactive calculators, auto-calculating Excel/Sheets dashboards, polished digital ebooks, and live data visualizations for creators and small businesses.
What I deliver: custom calculators (HTML/JS), formula-driven spreadsheets with charts, designed ebooks, and interactive dashboards for presentations.
I test everything before delivery and only ship work I'd trust myself. Need a tool that looks professional and actually works? That's what I build.
