How to use this tool?
This calculator computes your total work hours, regular vs. overtime hours, and gross pay based on your clock-in/out times and break.
- Enter Clock In & Clock Out – Use the time fields (24-hour format) for when you start and end work.
- Enter Break Start & Break End – Specify your unpaid break period. It must fall within your work hours.
- Set Hourly Rate ($) – Your standard pay per hour (e.g., 25.00).
- Set Overtime Threshold (hours) – The number of hours after which overtime applies (default 8).
- Click "Calculate" – The results show:
- Total Hours = (Clock Out - Clock In) minus break duration.
- Regular Hours = hours up to the threshold.
- Overtime Hours = hours beyond the threshold.
- Gross Pay = (Regular Hours × Rate) + (Overtime Hours × Rate × 1.5).
Note: All times must be in 24-hour format (e.g., 09:00, 17:00). The break must be entirely within the work period, and clock-out must be after clock-in.

Yes, just set the overtime threshold higher than your expected hours to avoid overtime calculation, or set it to 0 to treat all hours as overtime.
