How It Works

How to Calculate Work Hours

Subtract break time from daily hours, then multiply by the number of workdays.

Formula

Net Daily Hours = Hours Per Day - Break Minutes / 60

Total Hours = Net Daily Hours x Workdays

Worked Example

22 workdays, 8-hour days with 60-minute lunch, earning $30/hr.

workdays = 22hours_per_day = 8break_minutes = 60hourly_rate = 30
  1. 01Net hours per day = 8 - 60/60 = 7.0 hours
  2. 02Total work hours = 7.0 x 22 = 154.0 hours
  3. 03Total earnings = 154.0 x $30 = $4,620.00
  4. 04Total break time = 1.0 x 22 = 22.0 hours
