How to Calculate Work Hours
1. Record your start and end times
For each day you worked, note the time you started and the time you finished. Use a consistent format, such as 24-hour time (09:00 to 17:00) to avoid AM/PM confusion.
2. Subtract your breaks
Unpaid breaks should be removed from your total. If you took a 30-minute lunch, subtract 30 minutes from that day's total.
3. Convert minutes to decimal hours
Many payroll systems use decimal hours. Divide minutes by 60: 15 minutes is 0.25 hours, 30 minutes is 0.5 hours, and 45 minutes is 0.75 hours.
4. Add up the week
Sum the daily totals to get your weekly hours. Shiftfy does all of this automatically — just enter your times and the totals update instantly.
5. Understand overtime
Shiftfy shows any time over 40 hours in a week as overtime. Actual overtime rules vary by employer and location, so always confirm with your own payroll policy.
