Timesheet Calculator
About Tool
Managing payroll or tracking project hours requires precision to ensure fair compensation and accurate billing. This calculator simplifies the process of converting daily start and end times into a clean weekly total. It is designed to handle the realities of the workday, including mandatory break periods and overtime thresholds, providing a clear breakdown of "Time In" and "Time Out" for any standard work week.
Input Structure and Log Format
The tool utilizes a flexible textarea where you can log your hours for each day of the week. The expected format follows a simple pattern: Day, Start Time, End Time, and Break (minutes). For example, entering "Monday, 09:00, 17:00, 30" tells the system you worked an eight-hour shift with a half-hour unpaid break. This format allows for quick data entry without navigating through dozens of individual dropdown menus.
For those who need to turn these calculated hours into a request for payment, the data pairs perfectly with an Invoice Generator. If you are a freelancer providing a proof of service after the work is completed, you might also find a Receipt Generator useful for your records.
Handling Overtime and Breaks
One of the most useful features is the Overtime Threshold (Weekly Hours) input. By setting this value—typically 40 hours—the calculator will automatically distinguish between standard hours and overtime hours in the final summary. The Break (minutes) field is equally vital, as it subtracts non-working time from the total duration, preventing over-billing. All time calculations are performed using a 24-hour clock logic to avoid confusion between AM and PM entries.

Frequently Asked Questions
Do I have to use the 24-hour time format?
Yes, using 24-hour format (e.g., 14:00 for 2 PM) ensures the most accurate calculations and prevents AM/PM errors.
How does the break deduction work?
The number entered in the break column is treated as minutes. It is subtracted directly from the total elapsed time between your start and end times.
Can I calculate monthly totals?
The tool is optimized for weekly logs. For monthly totals, calculate each week separately and sum the results.
What happens if I work past midnight?
It is best to split the entry into two days: one ending at 23:59 and the next starting at 00:00 to ensure the logic calculates the duration correctly.
