Work Hours Calculator for Timesheet Accuracy

Timesheet errors often come from break handling and overnight shifts. This guide gives a reliable calculation workflow.

How to calculate using Work Hours Calculator

  • Enter start time, end time, and total break minutes.
  • Subtract breaks from shift duration to get worked time.

Work Hours Calculator formula

  • Worked minutes = (end time - start time) - break minutes.
  • Decimal hours = worked minutes / 60.
  • If end time is earlier than start, shift is treated as overnight.

Worked example

  • Start 09:00, end 17:30, break 30 min.
  • Worked time = 8h 00m.
  • Decimal hours = 8.00.
