Track hours worked across shifts with lunch-break deduction, overtime at 1.5x for hours over 40/week, and full pay breakdown.
Work hours are the total time between clock-in and clock-out, minus unpaid breaks. For payroll, they are usually converted to decimal hours (7 hours 30 minutes = 7.5 hours) and multiplied by the hourly rate, with overtime (over 40 hours per week in the US) paid at 1.5x. A time card calculator handles multiple shifts per day, lunch deductions, overtime across a workweek, and shows the gross pay breakdown for each shift and the total.
US federal rule: 40 hours / week
Federal default: 1.5x (time-and-a-half)
| Shift | Clock-in | Clock-out | Break (min) | Hours | |
|---|---|---|---|---|---|
| #1 | 7h 30m | ||||
| #2 | 7h 30m | ||||
| #3 | 7h 30m | ||||
| #4 | 7h 30m | ||||
| #5 | 7h 30m |
Times use 24-hour format. A clock-out earlier than clock-in is treated as an overnight shift (crosses midnight). Default 5 shifts represent a standard Mon-Fri workweek.

Total hours shown as 37:30 in HH:MM format (decimal: 37.50). Timesheet-ready.
The US Fair Labor Standards Act (FLSA) requires non-exempt employees to receive overtime pay of 1.5x the regular rate for any hours over 40 in a single workweek. Some states (notably California) also have daily overtime rules above 8 hours per day, but this calculator applies the federal 40-hour weekly rule.
The total across all shifts in your time card is summed first. Hours up to the threshold (default 40) are paid at the regular rate; anything above is multiplied by the overtime multiplier (default 1.5x). Decimal hours like 7.5 are converted back to HH:MM for traditional timesheets.

A time card calculator is a free payroll tool that computes hours worked and gross pay from clock-in and clock-out times. Our time card calculator handles multiple shifts, lunch break deductions, overtime at 1.5x for hours over 40 per week, and total pay breakdown. The time card calculator is used by employees to verify paychecks and by employers to track timesheet accuracy.
How it works
Our time card calculator totals hours worked and gross pay from clock-in and clock-out times, with lunch-break deduction and overtime at 1.5x for hours over 40.
Type your start time and end time for each shift. Use the 12-hour format with AM/PM. The time card calculator handles overnight shifts that cross midnight.
Type the unpaid lunch break duration in minutes. The default 30 matches a standard US lunch. The time card calculator deducts this from the gross shift duration.
Type your hourly wage in dollars. The time card calculator multiplies regular hours by this rate, then multiplies overtime hours (over 40/week) by 1.5x.
Use the 'Add shift' button to add more days or shifts to your time card. The time card calculator aggregates all shifts into weekly regular hours, overtime hours, and gross pay.
The time card calculator shows total hours worked, regular hours, overtime hours (over 40/week), regular pay, overtime pay, and gross pay. The table lists each shift with its individual hours for timesheet accuracy.
