SalarySum is a free set of pay calculators for workers in the United States. It helps you turn a salary into an hourly wage, work out overtime, and see what a raise means for each paycheck, with every formula shown so you can check the math yourself.
Who runs this site
SalarySum is built and maintained by Mubarak Hussain. I hold an engineering degree in Information Science and work professionally as a web application developer, which is the background I bring to building and testing these calculators.
I am not a tax professional, accountant or lawyer. The calculators do arithmetic using published rules and standard pay-period conventions; they don’t give personal advice.
How the calculators work
- Every formula is on the page. Each calculator explains its formula, works through an example, and shows a step-by-step breakdown of your own result.
- Official sources for rules. Overtime and pay rules are summarized from the U.S. Department of Labor and state labor departments. Tax figures, when we add paycheck calculators, will come from the IRS and each state’s revenue department, with the tax year shown on the page.
- Tested before publishing. Each calculator is checked against worked examples calculated by hand, at desktop and phone sizes, including invalid inputs.
- Runs in your browser. The numbers you type into a calculator are processed on your device and are not sent to our server or stored.
Keeping things up to date
Pay and tax rules change. Every calculator page shows when it was last reviewed. Tax-dependent pages will be updated each January when new federal and state figures are published.
Corrections
If you find a wrong number, an outdated rule or a bug, please contact us. Reports are checked against the original source, and confirmed errors are fixed and the page’s review date updated.
