Most wage-and-hour questions come down to one of a few situations. If you are figuring overtime for an hourly employee, start with the FLSA Overtime Calculator — it handles the regular rate and the effect of non-discretionary bonuses. When the employee is paid a fixed salary but their hours swing week to week, the Fluctuating Workweek Calculator applies the 0.5× half-time method instead. And when someone works two jobs at different rates in the same week, overtime is based on the weighted average — that is the Blended Overtime Calculator.
If the question is whether overtime was owed in the first place, two tools help before you ever run the numbers: the Exempt vs. Non-Exempt Calculator walks the salary and duties tests that decide whether an employee is entitled to overtime at all, and the Back Pay Calculator estimates what is owed — plus liquidated damages — when overtime was underpaid. For tipped staff, the Tip Credit Calculator checks whether cash wage plus tips clears the minimum wage. And for leave rather than pay, the FMLA Eligibility Calculator tests the three gates that decide who qualifies for job-protected leave.
Every tool is free, runs entirely in your browser, and shows its formula and sources so you can check the result. If you are new to the regular-rate concept that underlies most of them, the step-by-step overtime guide is the place to start.
