Work Hours Calculator
🇦🇺 Australia version
Australian full-time employees work a 38-hour week plus reasonable additional hours, and overtime rates come from modern awards and agreements rather than the national standards. This calculator totals the week from your clock times, compares it with 38 hours, and prices the extra time at a multiplier you copy from your own award.

Australia rules and figures
- The National Employment Standards set a 38-hour week for full-time employees, who can also be asked to work reasonable additional hours.
- Employees can refuse extra hours that are unreasonable, and hours can be averaged over up to 26 weeks under an arrangement.
- Overtime and penalty rates are set by modern awards and agreements, not by the NES.
- The Restaurant Industry Award 2020 pays 150% for the first two overtime hours on Monday to Friday and 200% after that.

How the Work Hours Calculator works
Net time for a day is the finish minus the start minus the unpaid break. A finish earlier than the start counts as the next day. The overtime rule begins as no premium, and a weekly rule starting after 38 hours is there to choose.
net minutes = (out − in, +24 h if out < in) − break; pay = regular × rate + overtime × rate × multiplier
- The target hours opens at 38, the length of the full-time week in the National Employment Standards. Part-time workers get the lesser of 38 hours and their agreed hours.
- Overtime starts as No overtime premium, because the multiplier is left empty by the data: awards and agreements set overtime and penalty rates, not the national standards.
- Choose a weekly rule and it will begin after 38 hours with a 1.5 multiplier already typed, which you should overwrite with the figure in your award.
- The Restaurant Industry Award 2020 is quoted as one example, paying 150% for the first two overtime hours Monday to Friday and 200% after that. The tool takes one multiplier, so it cannot model both steps at once.
- The pay currency symbol is $ and the timesheet is saved in your browser.
How to use the Work Hours Calculator
- Enter the days you worked. Give each day a start time, a finish time and an unpaid break in minutes.
- Look at the week against 38 hours. The target is set to 38. Read the plus or minus figure on the week tab to see time over or under.
- Add your rate and award multiplier. On the pay tab type your hourly rate. If your award pays overtime, pick a weekly rule and enter its multiplier.
- Adjust the threshold if needed. If your agreement starts overtime after other hours, change the weekly or daily threshold.
- Check a single shift. For a one-off shift, use the shift tab with clock in, clock out and break.
Example: A 42.5-hour week at $35, with and without a multiplier
Each day is 9 hours less a 30-minute break, which is 8.5 hours, so the week is 42.5 hours and 4.5 hours above 38. With no overtime premium the gross is 42.5 × $35 = $1,487.50. Switch on the weekly rule after 38 hours with a typed 1.5 multiplier and pay becomes 38 × $35 = $1,330.00 plus 4.5 × $52.50 = $236.25, a gross of $1,566.25. Your award may use different steps, so treat 1.5 only as a stand-in.
When to use the Work Hours Calculator
- Checking pay against the 38-hour week. Enter the days worked and read how many hours fall above 38.
- Pricing award overtime. Choose a weekly rule and type the multiplier from your award to see the extra pay.
- Night and early shifts. Enter the real clock times and the tool handles shifts that cross midnight.
- Weighing an extra shift. Add it to a row and see how many of its hours land above the threshold.
What the Work Hours Calculator does not do
- Pay is gross, before tax and superannuation.
- Only one overtime multiplier is used, so awards with stepped rates, such as 150% then 200%, are approximated.
- Penalty rates for weekends, evenings and public holidays are not modelled.
- Averaging arrangements over several weeks are not applied, since the tool works on one week.
- Leave loading, allowances and rostering rules from an award are outside its scope.
- The single shift tab applies the base rate with no overtime.
When something else is a better fit
- When you need take-home pay after tax and super, use the Payroll Calculator.
- When you just need to add durations, use the Time Duration Calculator.
- When your pay follows an award or enterprise agreement, use the award on the Fair Work Ombudsman website.
Questions about the Work Hours Calculator
Why does the tool start with no overtime premium?
Australian overtime rates come from awards and agreements, not the national standards, so there is no single multiplier to assume. Enter the one from your award.
How many hours is a full-time week?
38 hours, plus reasonable additional hours, under the National Employment Standards. The tool opens with 38 as its target.
Can I model 150% then 200%?
Not in one go. The tool applies one multiplier above the threshold, so split the week by hand if your award has two steps.
What happens on a shift past midnight?
Enter the true times, for example 22:00 and 06:00. Because the finish is before the start, the tool counts it as ending the following day, giving 8 hours before any break.
