How to calculate work hours from a time card
Convert each day's start and end time to minutes, subtract any unpaid break, then divide by 60 to get decimal hours. Shifts that cross midnight are added to the following morning automatically. Sum every day for your weekly total, and multiply by your hourly rate to estimate gross pay before tax.
From calculator to timesheet
This calculator is a quick one-off tool. If you fill in a paper timesheet every week, ShiftSheet does the same maths automatically, tracks overtime and night hours, captures your supervisor's signature, and emails a signed PDF to your manager.
FAQ
Does it handle overnight shifts?
Yes — if the end time is earlier than the start time, it rolls into the next day.
