Timesheet Calculator Australia
Free Australian timesheet and hours calculator. Enter the start time, finish time, and unpaid break for each day of the week to work out daily hours, a weekly total in both hours-and-minutes and decimal hours, and, with an optional hourly rate, your estimated gross weekly pay before tax.

How to calculate hours worked from a timesheet
A timesheet records the time you start and finish each day. To turn those clock times into paid hours you do three things for every day, then add the days together for a weekly total:
- Span: finish time − start time. For an overnight shift (finish earlier than start) add 24 hours.
- Paid hours: span − unpaid break minutes.
- Weekly total: add the paid hours for Monday through Sunday.
Converting hours and minutes to decimal hours
Payroll multiplies decimal hours by your rate, so 8 hours 30 minutes is 8.50 hours (30 ÷ 60 = 0.5). To estimate gross pay, multiply your total weekly decimal hours by your hourly rate.
Worked example
You work 9:00 to 17:30 Monday to Friday with a 30-minute unpaid lunch each day. Each day is 8 hours 30 minutes span minus 30 minutes = 8 hours, so the week is 8 × 5 = 40 hours. At $32.50 per hour that is 40 × $32.50 = $1,300.00 gross for the week (before tax, overtime, or penalty rates).
What this calculator does not include
This is a plain hours-and-pay tool. Overtime loadings, weekend and public-holiday penalty rates, allowances, superannuation, and PAYG tax withheld are set by your award or enterprise agreement and the ATO, and are not applied here. Under the Fair Work Act, employers must keep time-and-wages records for 7 years, so accurate timesheets matter.
Frequently asked questions
How do I calculate hours worked from start and end time?
Subtract the start time from the end time to get the total span, then subtract any unpaid break. For example, 9:00 AM to 5:30 PM is 8 hours 30 minutes; take off a 30-minute unpaid lunch and you have worked 8 hours. This calculator does the maths for every day and adds up the week for you.
How do I convert minutes into decimal hours?
Divide the minutes by 60. So 30 minutes is 0.5 hours, 15 minutes is 0.25 hours, and 45 minutes is 0.75 hours. Decimal hours are what you multiply by your hourly rate to work out pay, 8 hours 30 minutes becomes 8.5 hours.
How do I handle an overnight or night shift?
If the end time is earlier than the start time, for example a shift from 10:00 PM to 6:00 AM, turn on the 'Crosses midnight' toggle for that day. The calculator then adds 24 hours so the shift is counted as 8 hours rather than a negative number.
Do unpaid breaks count as hours worked?
No. An unpaid meal break is your own time, so it is subtracted from the hours you are paid for. Paid rest breaks (such as a 10-minute paid break) are not deducted because you remain on the clock. Enter only unpaid break time in the break field.
How long do employers have to keep timesheets in Australia?
Under the Fair Work Act, employers must keep time-and-wages records, including hours worked, overtime, and leave, for 7 years. Records must be in a legible form (in English), readily accessible to a Fair Work Inspector, and must not be false or misleading. Pay slips must be issued within one working day of payday.
What is a standard full-time work week in Australia?
Under the National Employment Standards, the maximum ordinary hours for a full-time employee are 38 hours per week, plus reasonable additional hours. Many awards spread these 38 hours across the week. Hours worked beyond ordinary hours may attract overtime or penalty rates set by the relevant award or agreement.
Does this calculator work out overtime and penalty rates?
No. This is a plain hours-and-pay calculator: it totals the hours you enter and multiplies them by a single hourly rate. Overtime loadings, weekend and public-holiday penalty rates, and allowances are set by your award or enterprise agreement and need to be added separately.
Sources & methodology
How we calculate this
This calculator works out paid hours for each day by subtracting the start time from the end time, adding 24 hours for any shift that crosses midnight, then deducting the unpaid break. Daily minutes are summed to a weekly total and converted to decimal hours; if you enter an hourly rate, weekly hours are multiplied by it to estimate gross pay before tax. It does not apply overtime, penalty rates, or PAYG withholding. Everything is computed in your browser, nothing you enter is stored or sent to a server.
