About EverydayCalc
EverydayCalc is a set of free online calculators that give you a clear answer and show you how the answer was worked out.
Who makes EverydayCalc
EverydayCalc is created and maintained by Muddasir Riaz. I build each calculator, write the guide that goes with it, and check the formulas against official sources before publishing. I started the site because many calculator pages give you a number but not the reasoning behind it. I want every result here to be something you can understand and verify.
Our mission
To give people simple, fast, mobile-friendly calculators for everyday work, pay and health questions, with the formula and examples right on the page.

How we keep calculators accurate
- Published formulas. We use standard formulas and show them on each page.
- Official sources. Work and pay rules come from the U.S. Department of Labor, the IRS and the Social Security Administration. Health categories come from the CDC. Each page lists its sources.
- Worked examples. Example tables on each page are generated with the same formula as the calculator, so you can compare results.
- Updates. Tax rules and wage limits change. We review pages when rules change and show the date of the last update.
- Corrections. If you find an error, tell us and we will check it and fix it.
Advertising and independence
EverydayCalc is free to use. We may show advertising or affiliate links in the future to cover the cost of running the site. If we do, they will be clearly separated from the calculators, and they will never change a calculation result.
Important notice
Results are estimates for information only. They are not financial, tax, legal or medical advice. For decisions that matter, talk to a qualified professional such as a payroll specialist, tax preparer, attorney or doctor.
