How this work hours calculator works

Each shift is calculated individually

For every day you enter, the calculator measures the time between start and finish, deducts the unpaid break, and stores both gross and net hours. All shifts are then summed into a weekly total shown in the daily breakdown.

Overnight shifts are handled automatically

If a shift ends after midnight, simply enter the next-day finish time. When the end time is earlier than the start time, the tool treats it as an overnight shift and adds 24 hours before calculating the duration.

Overtime is a planning estimate

The overtime result is based on the weekly threshold and multiplier you choose. Award rules, roster patterns, penalty rates, and paid breaks can all change the final payroll outcome — confirm the specifics with your award or payroll system before relying on it for pay calculations.

Australian standard work hours

In Australia, full-time employees work an average of 38 ordinary hours per week under the National Employment Standards (NES). That is why this calculator defaults the weekly overtime threshold to 38 hours.

The spread of those hours varies by industry, award, or enterprise agreement. Some employees trigger overtime based on weekly totals, others on daily limits, weekends, public holidays, or rostered patterns. Use this tool as a fast hours-worked calculator and overtime estimator, then confirm the specific pay rules in your award before relying on the pay figures.

Frequently Asked Questions

How many hours is full-time in Australia?

For most employees, full-time work in Australia is an average of 38 ordinary hours per week under the National Employment Standards. The exact spread of hours can vary under an award, enterprise agreement, or contract.

How do I calculate hours worked from start and end times?

Subtract the start time from the end time, then deduct any unpaid meal or rest break. For example, 9:00 AM to 5:00 PM with a 30-minute break is 7.5 net hours. This calculator does that automatically across all your shifts for the week.

What is the standard overtime rate in Australia?

There is no single national overtime rate. Many Australian awards use time-and-a-half (1.5×) and double time (2×) as common benchmarks, but the exact multiplier depends on your award or enterprise agreement. Use the multiplier selector to match your situation.

Does this calculator handle overnight shifts?

Yes. If a shift ends after midnight, simply enter the next-day finish time. When the end time is earlier than the start time, the calculator treats it as an overnight shift and adds 24 hours to the duration before calculating.

How is overtime calculated?

The calculator sums all net weekly hours, then compares the total with your weekly overtime threshold. Any hours above that threshold are treated as overtime and priced at your chosen multiplier.
