Total Gross Pay
💡 US Overtime Law (FLSA): Federal law requires 1.5× pay for all hours over 40/week. California also requires 1.5× after 8 hrs/day and 2× after 12 hrs/day. Alaska and Nevada require daily OT after 8 hours. Always check your state's Department of Labor for exact rules.

Gross Pay This Period
💡 US Pay Note: This is a gross pay estimate. Actual take-home pay depends on your federal filing status (W-4), state income taxes, FICA (Social Security 6.2% + Medicare 1.45%), health insurance, and 401(k) contributions. Use this as a quick reference, not for official payroll.
Frequently Asked Questions
How do I calculate my total work hours from a time card?
Enter your clock-in and clock-out times for each day of the week in the Time Card tab. Include your break time in minutes. The calculator subtracts breaks and sums up all your daily hours to give you a weekly total. It also handles overnight shifts (e.g., 10 PM to 6 AM).
What counts as overtime in the US?
Under the federal FLSA, any hours over 40 in a workweek must be paid at 1.5× your regular rate. Some states have stricter rules: California requires daily overtime after 8 hours, and double time after 12 hours or on the 7th consecutive day. Alaska and Nevada also have daily overtime rules.
How is overtime pay calculated?
Overtime pay = Overtime hours × (Regular hourly rate × OT multiplier). For example: 5 OT hours × ($18 × 1.5) = $135 in overtime pay, on top of your regular pay of 40 × $18 = $720, for a gross total of $855.
What is the difference between gross pay and net pay?
Gross pay is your total earnings before any deductions. Net pay (take-home pay) is what's left after taxes, Social Security, Medicare, health insurance, and other withholdings. The Pay Calculator estimates gross pay; your actual net pay will be lower based on your tax bracket and deductions.
How do I add time intervals in the Hours Calculator?
In the Hours Calc tab, enter each time interval in hours and minutes (or use the H:MM format). You can add as many rows as needed. Choose whether to add them all together or subtract from the first entry. The result shows in your chosen format: hours & minutes, decimal hours, or total minutes.
How do I convert decimal hours to hours and minutes?
Multiply the decimal part by 60. For example: 7.75 hours = 7 hours and (0.75 × 60) = 45 minutes = 7h 45m. Alternatively, 8.5 hours = 8h 30m. The Hours Calculator does this conversion automatically.
Can this handle overnight or split shifts?
Yes! The Time Card Calculator automatically detects overnight shifts. If your time out is earlier than time in (e.g., in at 10:00 PM, out at 6:00 AM), it adds 24 hours to correctly calculate the 8-hour shift.
How many hours per day is full-time vs part-time?
In the US, full-time is typically 35–40 hours per week, or 7–8 hours per day. Part-time is generally under 35 hours/week. The ACA (Affordable Care Act) defines full-time as 30+ hours/week for benefits purposes. Exact definitions vary by employer.
