About Me
Sue Chea here. I am passionate about creating high-quality, free tools and resources for the online community. I believe in giving back, and this is my way of making a meaningful contribution. My goal is to provide a comprehensive collection of user-friendly, free online calculators to simplify everyday calculations.
More than 90% of the calculators on this site are based on well-established formulas and equations from textbooks—ensuring accuracy and reliability. Tools like the mortgage calculator and BMI calculator follow widely accepted methodologies, while calculators with multiple approaches, such as the Ideal Weight Calculator, present results from all recognized formulas.
To uphold accuracy, these financial calculators are reviewed by experts from leading personal finance firms, and the health calculators are evaluated and approved by licensed medical professionals. Additionally, over 99% of the site’s content is developed in-house, with select excerpts from Wikipedia under the GNU Free Documentation License. Financial content is meticulously crafted and reviewed, while health-related descriptions undergo expert medical review.
