Overtime pay calculator

Enter your hourly rate and the hours you worked this week. The calculator splits them at the overtime threshold (40 hours by default) and shows regular pay, overtime pay at time-and-a-half, and your total gross for the week.

How the 40-hour rule works

Under the federal FLSA, non-exempt hourly employees earn at least 1.5× their regular rate for hours over 40 in a single workweek. The important details people get wrong:

• It's per workweek, not per pay period. On a bi-weekly paycheck, a 47-hour week followed by a 33-hour week is 7 hours of overtime — the two weeks never average out to 80. (More on this in our pay periods guide.)
• It's based on hours actually worked. Unpaid lunch breaks don't count toward the 40 — subtract them first with the lunch break calculator.
• Long days alone don't trigger federal OT. Four 10-hour days is 40 hours — no federal overtime. A few states (California notably) add daily overtime rules on top.
• Some states go further. California pays daily OT over 8 hours and double time over 12; Colorado, Alaska, and Nevada have daily rules too. When state and federal rules differ, the worker gets whichever is more generous.

Worked example

45 hours at $20/hr with a 40-hour threshold: 40 × $20 = $800 regular, plus 5 × $30 = $150 overtime — $950 total. That extra 5 hours pays like 7.5 regular hours, which is why unplanned overtime quietly wrecks job budgets.
