Free online calculators for everyday money, time and health

EverydayCalc is a growing set of free calculators for the questions people ask every week. How many hours did I work this week, and did I earn overtime? What will my paycheck be after taxes? What is my BMI, and what weight range counts as healthy for my height? Each calculator sits above a plain-English guide that explains the formula, shows examples, answers common questions and links to official sources such as the U.S. Department of Labor, the IRS and the CDC.

The tools are written and maintained by one person, Muddasir Riaz, and we add new calculators and guides regularly. If you spot a mistake or want a calculator we do not have yet, contact us.
