How to calculate hours worked

  1. Enter the start and end of the shift. Overnight shifts are handled automatically.
  2. Add your unpaid break in minutes (or as 0:45).
  3. Optionally enter the number of days and an hourly rate to see totals and pay.

Worked example

Hours = (end − start) − break.

8:30 AM to 5:15 PM with a 45-minute lunch: 17:15 − 8:30 = 8:45, minus 0:45 = 8:00 hours. Over 5 days that's 40 hours; at $18/hour, $720.
