How to use the time card calculator
- Choose a weekly or biweekly pay period.
- Enter each clock-in and clock-out time. Add unpaid break minutes and a second shift when needed.
- Alternatively, enter a daily total such as 8:30 or 8.50 instead of clock times for that day.
- Set an hourly rate, weekly overtime threshold or time-rounding rule if they apply.
- Review the live totals, then print, copy, download or explicitly save a local draft.
Example calculation
A shift from 9:00 AM to 5:30 PM is 8 hours 30 minutes elapsed. Subtracting a 30-minute unpaid break produces 8 hours worked, or 8.00 decimal hours.
Work hours, payroll hours and timesheets
This page keeps one authoritative calculation for overlapping needs such as a work-hours calculator, payroll-hours calculator and timesheet calculator. You can use clock-in/out entries or a direct daily total in hours and minutes or decimal hours. Clock time is shown as hours and minutes, while the decimal total is ready to compare with systems that accept decimal hours.
Overnight shifts, overtime and rounding
If an end time is earlier than its start time, ClockSlate treats the end as the following day. Weekly hours above the threshold are shown as overtime; in a biweekly card, each seven-day week is evaluated independently. Time rounding changes the clock events before the worked duration is calculated.
Frequently asked questions
Can I enter military time?
Yes. Select 24-hour format and enter values such as 1730 or 17:30. Entries with AM or PM are also understood.
Does the calculator send or save employee data?
No. Entries and calculations remain in the browser. Nothing is saved automatically. Settings or a full draft are stored on this device only when you explicitly choose the corresponding save action; exports and share links are also created only when requested.
Is overtime always due after 40 hours?
No. Rules vary by location, employer and occupation. The 40-hour default is editable and the result should be checked against the policy and law that apply to you.
