🇺🇸 United States Overtime Pay Calculator

Methodology

How this calculator works

The calculator starts with total hours in a single workweek, subtracts unpaid break hours and compares paid hours with the selected overtime threshold, defaulting to the federal 40-hour baseline. Hourly straight-time pay, shift differential, nondiscretionary bonus and entered commission or piece-rate pay are included in the regular-rate base. Overtime premium is then calculated on the regular rate, using the entered multiplier, while optional double-time or company-policy hours are separated so the result shows regular hours, overtime hours, premium pay and total weekly gross pay.

Worked example

Reading the result

At $20 per hour for 48 paid hours, the federal baseline creates 8 overtime hours. If a $100 nondiscretionary bonus is entered, the regular rate increases because that bonus is spread across paid hours before calculating the overtime premium. This is more transparent than simply multiplying $20 by 1.5.

Accuracy checklist

Validate your United States estimate

1. 1Separate base cash salary, bonus, overtime, taxable benefits and employer-paid items before calculating. Use the correct pay frequency and Federal FLSA baseline setting, and do not subtract an employer contribution from take-home pay unless it is genuinely withheld from the employee.
2. 2Compare gross pay, taxable pay, employee deductions and net cash as separate result lines. This makes it easier to find whether a difference comes from income tax, a capped contribution, an optional deduction or the conversion between annual and pay-period amounts.
3. 3Check the United States estimate against an actual payslip and US Department of Labor — overtime pay guidance. Payroll calendars, cumulative withholding, rounding, benefits, arrears and one-off payments can create period-by-period differences even when the annual method and inputs are reasonable.
4. 4Save the inputs, selected options and calculation date with the result. If the estimate informs a payment, return, contract or application, rerun it when the Federal FLSA baseline rules or your underlying figures change and compare the updated breakdown with the earlier version.
