How the Timesheet Calculator Works

This timesheet calculator tracks your daily clock-in and clock-out times across a full workweek, subtracting break durations to determine net hours worked each day. Unlike the time card calculator which uses a per-day overtime threshold, this calculator applies the FLSA standard: overtime kicks in after 40 total hours in a workweek, which is how most US employers calculate overtime.

You can switch between weekly and biweekly pay periods. In biweekly mode, each week's overtime is calculated independently (per FLSA rules — overtime cannot be averaged across two weeks). The calculator supports custom hourly rates, overtime thresholds, and overtime multipliers to match your employer's pay structure.

For a quick overtime estimate without entering daily times, try the overtime calculator. To convert between hourly and annual pay, use the salary calculator. If you need to add or subtract time values, the hours calculator is a simpler option.

Frequently Asked Questions

How is weekly overtime calculated?
Under the Fair Labor Standards Act (FLSA), overtime is calculated on a weekly basis. Any hours worked beyond 40 in a single workweek must be paid at 1.5× the regular rate. This calculator uses the same method — it totals all daily hours and applies overtime only to the hours exceeding the weekly threshold.
Can overtime be averaged across two weeks in a biweekly period?
No. Under FLSA rules, overtime must be calculated per individual workweek, even if you're on a biweekly pay schedule. For example, if you work 50 hours in week 1 and 30 hours in week 2, you still owe 10 hours of overtime for week 1, even though the biweekly total is 80 hours (averaging 40/week).
Does this handle overnight shifts?
Yes. If your clock-out time is earlier than your clock-in time (e.g., in at 22:00, out at 06:00), the calculator treats it as an overnight shift crossing midnight and correctly calculates 8 hours.
What's the difference between this and the Time Card Calculator?
The Time Card Calculator uses a per-day overtime threshold (e.g., overtime after 8 hours in one day, as required in California). This Timesheet Calculator uses a per-week threshold (e.g., overtime after 40 hours in a week, the federal FLSA standard). Choose based on your state's laws or employer policy.
How do I account for different break lengths each day?
Enter the break duration in minutes for each day individually. For example, enter 30 for a 30-minute lunch or 60 for a full hour. Days with no break can be left at 0.
