Welcome to uscalculator.site – your go-to destination for easy-to-use, reliable, and free online calculators.
We are a team of dedicated IT professionals with a shared passion for building high-quality tools and content that help people in their everyday lives. Our mission is simple: to make useful calculators accessible to everyone, completely free of charge.
Launched in 2025, our website offers a wide variety of calculators neatly organized into four main categories:
- Financial Calculator
- Fitness & Health Calculator
- Math Calculator
- Others Calculator
All of our tools are developed in-house, and many are based on trusted formulas found in textbooks—like our Mortgage Calculator and BMI Calculator. When there are multiple accepted methods (for example, in our Ideal Weight Calculator), we show results from all major formulas to help you make informed decisions.
Some of our calculators—such as the Dowry Calculator, Love Calculator—are created purely for fun and are powered by our own custom formulas.
To ensure accuracy and trust, our financial calculators have been reviewed by professionals from top personal finance advisory firms. Likewise, our health-related tools and their descriptions have been checked and approved by local medical doctors.
Over 99% of the written content on our site is original and created by our team. A small portion comes from reliable sources like Wikipedia under open-source licenses.
We believe that useful information and helpful tools should be easy to access. That’s why we’re proud to offer a wide collection of free calculators designed to simplify your daily tasks—whether you’re managing money, tracking fitness, or solving math problems.
