Work Hours & Timesheet Calculator

About the Work Hours & Timesheet Calculator

Work Hours & Timesheet Calculator turns a list of shifts into a clear timesheet. Enter each shift’s date, start and end time, unpaid break and, if you like, an hourly rate. The tool calculates the hours worked for every entry, totals them per day and per week, and shows overtime above a daily threshold you choose.

Overnight shifts are handled automatically: when the end time is earlier than the start time, the shift is treated as ending the next day. Estimated earnings are simply hours worked multiplied by the rate you entered — no overtime premium, tax or deductions are applied. Entries can be remembered in this browser only, and you can clear the saved copy at any time.

How to use

1. Set the daily overtime threshold (8 hours by default) and, if needed, the currency symbol.
2. For each shift, enter the date, start time, end time and unpaid break in minutes. Add an hourly rate if you want earnings estimated.
3. Click Add entry for more shifts — times and rate are copied from the previous entry to save typing.
4. Read the weekly summary, daily hours, total breaks, overtime and estimated earnings.
5. Click Download CSV for a spreadsheet-ready timesheet. Use Clear saved data or Reset to remove stored entries.

Best practices

• Enter times in 24-hour or AM/PM format consistently, as your device’s time picker shows them.
• Record unpaid breaks only; paid breaks are part of working time.
• Set the overtime threshold to the rule in your contract or local law, and check whether it is daily or weekly.
• Use one entry per continuous shift; split shifts can be entered as two entries on the same date.
• Turn off “Remember my entries” on shared or public computers.

Benefits

• Fast, accurate weekly hours without a spreadsheet formula.

• A clean CSV to attach to invoices or send to an employer.
