Work out your overtime pay at time-and-a-half or double time, and see your total gross pay for the week — with a clear, checkable breakdown. Built by the Salaryitis Editorial Team on the federal FLSA overtime rule · Reviewed against our editorial standards · Last reviewed 2026
Under the federal Fair Labor Standards Act (FLSA), most hourly (non-exempt) employees must be paid a premium for extra hours. Any time you work beyond your overtime threshold — usually 40 hours in a single workweek — has to be paid at no less than one-and-a-half times your regular hourly rate. That premium is why overtime is often called "time-and-a-half."
The math is simple once you split your hours into two buckets. Your first hours, up to the threshold, are paid at your normal rate. Every hour above the threshold is paid at your rate multiplied by 1.5 (or 2.0 for double time). Add the two buckets together and you have your total gross pay for the period. This calculator does that split for you and shows each piece, so you can check your paycheck line by line.
Time-and-a-half (1.5×) is the federal minimum. Double time (2×) is not required by federal law, but some states and many union or company agreements require it in specific situations — for example, hours worked beyond 12 in a single day, or on a seventh consecutive workday. If your employer owes you double time, switch the multiplier above to see the difference.
Federal overtime is measured weekly: it kicks in after 40 hours in a workweek, no matter how those hours are spread across days. A handful of states, most notably California, also require daily overtime after 8 hours in a day. Because you can change the threshold in this tool, you can model either rule — set it to 40 for the federal weekly standard or 8 to check a single long day.
