Construction Timesheet Calculator
Add each shift and see weekly regular and overtime hours, in the browser.
This calculator converts daily start, end, and unpaid break times into weekly totals and splits them into regular and overtime hours. It is an estimator for planning and checking timesheets, not a payroll system.

What this calculator does
Enter a start time, end time and unpaid break for each day. The calculator totals the week, subtracts breaks, and splits the result into regular and overtime hours using the daily and weekly thresholds you set. It also shows the decimal-hours equivalent used by many payroll systems.
How construction teams use it
Supervisors check a crew's week before it is submitted; foremen correct a missed break or a late finish; office staff verify that a timesheet matches the site diary. Because everything runs in the browser, it works on a phone at the site gate or on a laptop in the office.
Regular hours vs overtime hours
Regular hours are the worked hours up to your threshold; overtime hours are everything above it. The thresholds are inputs, not fixed rules: daily overtime applies after a set number of hours in a day, and weekly overtime applies after a set number of hours in the week.
Example calculation
Monday 07:00 to 16:00 with a 30-minute unpaid break is 8.5 worked hours. With a daily threshold of 8 hours, that day contributes 8 regular hours and 0.5 overtime hours. A full week is summed the same way, and weekly overtime is applied on top of the weekly threshold.
How timesheets support payroll and reporting
A clean weekly timesheet is the source for payroll totals and for workforce reporting such as attendance, labour hours per site and hours per crew. Consistent start, end and break entries keep those reports accurate and comparable week to week.
Common timesheet mistakes
The most common errors are forgetting unpaid breaks, mixing 12-hour and 24-hour entry, rounding inconsistently, and counting travel time as worked time. Check each day against the daily report before submitting, and keep the same entry format all week.
Frequently asked questions
- Is the construction timesheet calculator free?
- Yes. The calculator is free to use in the browser and does not require an account.
- Does it apply the overtime law in my province or country?
- No. It applies the daily and weekly thresholds you enter. Overtime rules differ by jurisdiction and by employment agreement, so verify current requirements with official sources.
- Can I use it for a full crew?
- The calculator handles one person's week at a time. Run it per crew member, or record hours per person in FastBuild to total a whole crew automatically.
- Why does the total differ from my payroll system?
- Small differences usually come from rounding rules, break handling, or a different overtime threshold. Compare the worked hours first, then the threshold, then the rounding.
- Can I print or save the timesheet?
- Use your browser's print option to print or save the weekly timesheet as a PDF. Hours are not stored on a server by this tool.
