About WorkHoursTools
Free calculators for the work-hours math that comes up every pay period.
Why this exists
Turning clock-in and clock-out times into a payroll-ready number is simple in theory and fiddly in practice the moment breaks, overnight shifts, overtime rules, or decimal-hour conversions get involved. WorkHoursTools started as a small set of calculators built to remove that friction — enter the numbers you have, get an answer immediately, with the formula shown so the result is easy to verify rather than a black box.
How the calculators are built
Every calculator runs entirely in your browser using the same shared calculation logic, so the same inputs produce the same result no matter which tool you're on. There's no account, no signup, and no data sent to a server — see the Privacy Policyfor details. The site is independently built and maintained.
What the tools are not
WorkHoursTools is a calculation aid, not a source of legal, tax, or payroll advice. Overtime thresholds, break requirements, and rounding rules differ by jurisdiction and employer — verify anything that affects actual pay with your employer, payroll provider, or a qualified professional. More detail is in the Terms of Service.
