About the Time Card Calculator
A time card (timesheet) calculator totals the hours you worked each day from your start and end times, minus any unpaid break, then sums the week. It splits the total into regular and overtime hours (over 40 by default, paid at 1.5×) and, if you enter an hourly rate, works out your gross pay. Times that cross midnight are handled automatically.
How Time Card Calculator works
Daily hours are:
Hours = (clock-out − clock-in) − break
The week is the sum of all days. Overtime is anything over the weekly threshold (40 hours by default):
Pay = regular hours × rate + overtime hours × rate × 1.5
Example: in 9:00, out 17:30, 30-minute break → 8.0 hours that day. Five such days = 40 regular hours; a sixth day becomes overtime.
Common uses
- Total weekly work hours from daily clock-in / clock-out times
- Subtract unpaid breaks automatically
- Split hours into regular and overtime (1.5×)
- Calculate gross weekly pay from an hourly rate
Frequently asked questions
How do I calculate hours worked?
Subtract the start time from the end time, then subtract your break. For example 9:00 to 17:30 with a 30-minute break is 8 hours. This tool does it for each day and totals the week.
How is overtime calculated?
Hours over the weekly threshold (40 by default) are overtime, usually paid at 1.5× the normal rate. You can change the threshold.
Does it handle shifts past midnight?
Yes — if the end time is earlier than the start time, the calculator assumes the shift crossed midnight and adds 24 hours.
Is my timesheet data saved?
No. Everything is calculated in your browser; nothing you enter is uploaded or stored.
