Overtime Pay Calculator
Calculate your exact overtime pay under the federal FLSA and state rules with this free 2026 calculator. Enter your hourly rate, regular hours, overtime hours, and (if you're in California or working extreme shifts) any double-time hours to see your total weekly and annual gross pay. The default overtime multiplier is 1.5× (time-and-a-half), the FLSA standard for hours worked over 40 per workweek, but you can adjust it to 2× for double time or a custom multiplier if your union contract specifies otherwise.
Federal vs State Overtime Rules in 2026
The federal FLSA sets the floor: 1.5× the regular rate for hours worked beyond 40 in a single workweek. But several states go further. California requires time-and-a-half after 8 hours in a single day, and double time after 12 hours. Alaska, Nevada, and Colorado also have daily overtime thresholds. In Texas, Florida, and most other states, only the federal 40-hour rule applies. Always check the stricter of the two — that's the rule your employer must follow.
How to Read Your Paystub for Overtime
Overtime should appear as a separate line item on your paystub, typically labeled "OT," "Overtime," or "1.5x." Verify that the OT rate shown is exactly 1.5× your base rate (or 2× for double time). If you receive shift differentials, non-discretionary bonuses, or commissions, those must be blended into your "regular rate" before the multiplier is applied — a common source of underpayment.
