Confirm eligibility before calculating
Employment rules can apply different overtime tests according to wage level, occupation, contract and the nature of the claim. A contract or company policy can also provide a benefit beyond the statutory minimum. Do not use a multiplier until the employee's basis for entitlement and the applicable local rule are identified.
Build the hourly rate
the relevant labour authority's amendment FAQ illustrates ordinary rate of pay for a monthly-rated employee as monthly wages divided by 26. The hourly rate is the ordinary rate divided by normal hours of work per day. If normal daily hours are eight, a $3,120 monthly wage produces an ordinary rate of $120 and an hourly rate of $15.
Apply the correct work context
| Context | Common rate shown in the relevant labour authority guidance | What to verify |
|---|---|---|
| Beyond normal hours on a normal workday | At least 1.5 times hourly rate | Eligible overtime hours |
| Overtime beyond normal hours on a rest day | At least 2 times hourly rate | Rest-day rules and prior normal hours |
| Beyond normal hours on a paid public holiday | At least 3 times hourly rate | Holiday and substitution status |
Work during normal hours on a rest day or public holiday can follow a different calculation from overtime beyond normal hours. Keep those hours in separate rows.
Worked normal-day example
Using the $15 hourly rate above, three eligible overtime hours on a normal workday at 1.5 times gives $67.50. The calculation is $15 × 1.5 × 3. This is gross overtime pay before employee deductions and assumes the wage amount and eligibility basis are correct.
Reconcile hours with approvals
- Date and scheduled normal hours
- Actual start and end times
- Meal or unpaid break
- Overtime category and hours
- Supervisor approval or system record
- Rate, multiplier and gross amount
Round only where the employer's lawful method requires it. Rounding each shift can produce a different total from rounding after the pay period.
Watch the 45-hour week separately
The general maximum normal working week was reduced to 45 hours under the 2022 amendments. Weekly scheduling and overtime payment are connected but not identical questions. A schedule can redistribute normal hours across days, and rest-day or holiday work has its own treatment.
Check the payment month
Overtime can be paid later than basic wages under the applicable timing rules. Match overtime to the work date even when it appears on the following payslip. This prevents an apparent missing payment from being confused with the permitted payroll cycle.
Use the official Act and current guidance
Read the ILO working time guidance for cross-border context, then identify the current employment rule in the jurisdiction that applies. For a disputed amount, bring the contract, time records, approvals and payslips to the relevant labour authority or a qualified adviser.
Separate wages used for the rate from unrelated payments
The statutory definition of wages and exclusions matter when constructing ordinary rate of pay. Do not add every reimbursement, employer contribution or benefit to monthly wages without checking the Act and contract. Equally, do not assume basic salary is always the only relevant amount.
Worked public-holiday overtime example
Using a $15 hourly rate, two hours beyond normal hours on a paid public holiday at 3 times gives $90 for that overtime portion. Payment for the normal holiday hours is a separate part of the holiday-work calculation. Keep the ordinary-hours and excess-hours rows separate so one multiplier is not applied to the entire day.
Audit the payslip when hours cross midnight
Night shifts can cross a rest day or public-holiday boundary. Record the actual timestamp for each segment and the employer's workday definition. A single total of eight overtime hours may hide hours that belong to different rate categories.
Turn a time record into an auditable overtime row
For every overtime entry, preserve the work date, start and end time, unpaid break, normal scheduled hours, workday category, approved overtime hours, wage input, divisor, hourly rate and multiplier used. The calculation should show these inputs separately. A total such as “12 overtime hours” is not enough when the hours cross different workday categories.
Consider a shift that begins before midnight and ends on a public holiday. Split the timestamps at the boundary and ask how the employer defines the workday. Do not apply one multiplier to the full shift without checking the relevant normal-hours and overtime treatment. Keep normal holiday payment and excess-hours overtime as separate rows.
Three checks before disputing the amount
- Confirm the employee and wage fall within the relevant legal or contractual coverage.
- Confirm which earnings payroll included in the ordinary-rate input and which payments were excluded.
- Match approved hours to the payslip period, allowing for a documented later payroll cycle where applicable.
If the calculator and payslip differ, change one input at a time. First test the wage amount, then daily or hourly rate, then hours, then multiplier. This isolates the source of the difference and produces a payroll question that can be answered. Preserve rosters, clock records, approvals and the employer's calculation because a later dispute depends on evidence, not only the employee's reconstructed total.
