How the hours are counted

  • Hours = clock out − clock in − break.
  • An out time earlier than the in time counts as the next day (night shift).
  • Overtime: US federal law (FLSA) requires at least 1.5× pay for hours over 40 in a workweek. Each week is counted on its own.
  • Some states add daily overtime, for example California after 8 hours in a day. This calculator uses the weekly rule only.

Minutes to decimal hours

Payroll systems often want decimal hours: minutes ÷ 60.
