Techmaker started with a simple idea: make construction cost estimation fast, accurate, and free for everyone. That first tool the Construction Cost Estimate Calculator for the USA, UK, and Canada — was built by Muhammad Arslan, a Software Engineer with over 5 years of experience working alongside contractors and estimators.
But that was just the beginning.
A New Vision
Muhammad is a Software Engineer with a bigger goal: to build the most user-friendly, visually clear, and feature-rich collection of free online calculators on the web.
You’ve probably seen sites like Calculator.net huge libraries of useful tools, but often built with basic HTML, outdated design, and confusing layouts. Many users get lost or frustrated. Techmaker is changing that.
Our mission is simple:
Create beautiful, intuitive, and powerful calculators for everything finance, construction, health, math, conversions, and more so anyone can get accurate results without confusion.
