How the Work Hours Calculator Works

This free work hours calculator helps you track your weekly schedule with daily start and end times. It automatically calculates net working hours after break deductions, weekly totals, and overtime.

Weekly Overtime: Hours exceeding your weekly threshold (default 40 hours) are flagged as overtime and calculated at 1.5x your hourly rate. This follows standard US overtime regulations under the FLSA.

Monthly Estimates: Monthly projections use the standard 4.33 weeks per month multiplier for accurate annual planning.

Want to skip manual entry entirely? Fill the Timesheet automatically generates timesheets from your Google Calendar, Microsoft Teams, Zoom, and Jira events.

Frequently Asked Questions

How do I calculate my weekly work hours?

Enter your start time, end time, and break duration for each working day. The calculator subtracts breaks from your total time and sums all days to give you accurate weekly hours. For example, working 9:00-17:00 with a 30-minute break gives you 7.5 hours per day, or 37.5 hours across a 5-day week.

How is overtime calculated?

Hours exceeding your weekly overtime threshold (default 40 hours) are flagged as overtime and calculated at 1.5x your hourly rate, following standard US overtime regulations under the FLSA. You can adjust the threshold to match your employment agreement.

Can I track monthly work hours?

Yes. The calculator automatically estimates your monthly hours by multiplying your weekly total by 4.33 (the average number of weeks per month). This gives you an accurate projection for budgeting and invoicing.

Can I export my work hours to Excel?

Yes. Click the "Export to Excel" button to download a .xlsx file containing your daily schedule, weekly summary, overtime breakdown, and pay estimates. The file is ready for record-keeping or submitting to your employer.
