HR Math HubAbout HR Math Hub
HR Math Hub is a set of free calculators for the pay and HR questions people search for most: what a paycheck will actually be, how bonuses and overtime are taxed, how much PTO has been earned, whether someone qualifies for FMLA leave, and what a 401(k) can do over time.
Why it exists
Most pay calculators bury the answer under sign-up forms and long pages. These give you a result as you type, explain the numbers in plain language, and show the assumptions behind them. Nothing you enter is sent to a server.
Who builds it
HR Math Hub is built by Genial Software Solutions Inc., a U.S.-registered company that also runs GRC Training Online, which provides live and recorded HR compliance webinars on topics such as FMLA, wage and hour, payroll and documentation.
How we keep it accurate
- Tax figures come from published IRS and Social Security Administration sources and are updated each year.
- HR rules summarize U.S. Department of Labor guidance.
- Every calculator states its assumptions on the page and in How we calculate.
- Found a mistake? Tell us and we will check it.
