Unpaid breaks
Each day’s hours are the time from start to finish, less the unpaid break. The default week of five 9:00 am to 5:30 pm days with a 30-minute unpaid lunch comes to 40h 00m. A night shift from 10:00 pm to 6:30 am with a 30-minute break is 8h 00m: when the finish time is earlier than the start, the calculator treats it as finishing the next morning.
Send hours to weekly pay
Under the total, follow the link to open the weekly pay calculator with your hours already filled in, then add your hourly rate to see your pay after tax. For a fortnight, the link uses your average hours a week. If some of those hours were overtime or on weekends, the overtime and penalty rates calculator works out the higher rates.
Frequently asked questions
How do I work out hours worked in decimal?
Divide the minutes by 60 and add them to the hours. 7 hours 45 minutes is 7 + 45 ÷ 60 = 7.75 hours, and 7 hours 20 minutes is about 7.33 hours. The calculator shows both forms.
Are breaks paid?
It depends on your award, agreement or contract, which sets the breaks you get and whether each one is paid. Only enter breaks that are unpaid; paid breaks count as time worked.
How many hours is full time?
Under the National Employment Standards, a full-time employee can be asked to work up to 38 ordinary hours a week, plus reasonable additional hours. Some awards and agreements set fewer, such as 37.5 or 35 (Fair Work, checked 12 October 2026).
