Questions people ask

How do I calculate hours worked?

Subtract the start time from the end time and take off unpaid breaks. 9:00 AM to 5:30 PM is 8 hours 30 minutes; minus a 30-minute lunch that is 8 hours.

How do I convert minutes to decimal hours?

Divide the minutes by 60. 15 minutes is 0.25 hours, 30 minutes is 0.5 and 45 minutes is 0.75, so 7 hours 45 minutes is 7.75 hours.

What time do I clock out after 8 hours?

Add 8 hours plus your unpaid break to your start time. Starting at 8:15 AM with a 45-minute lunch, you clock out at 5:00 PM.

Are breaks paid?

Under federal rules, short rest breaks of 5 to 20 minutes are paid work time; meal breaks of 30 minutes or more when you are fully relieved of duty are not. Several states require meal or rest breaks.
