How this work hours calculator works

It adds up the hours between each day's clock-in and clock-out, subtracts your breaks, and totals the week for you.

  • Daily hours = (clock-out − clock-in) − break time.
  • Weekly total = the sum of every day's hours.
  • Regular vs. overtime: hours up to 40 per week count as regular; anything above is overtime (US FLSA — thresholds vary by country and state).

Results update as you type, including your daily average and total break time.
