Overtime and Employment Claims Calculator
Calculate your claims for work beyond 45 hours a week, weekly rest days and public holidays.
The working week is 45 hours. Work beyond that counts as overtime and is paid at 150 per cent of the normal hourly rate. Work on a weekly rest day and work on national and public holidays are calculated as separate items.
Calculator
See your claim for the period based on the weekly average.
The result is gross; income tax and social security deductions have not been applied. Interest is not included — interest may run on the claims from the date of termination or default.
Enhanced pay rates
- Overtime (beyond 45 hours): Hourly rate × 1.5
- Work on a weekly rest day: Since the pay is treated as already made, an additional hourly rate × 1.5
- National and public holiday work: One additional day's pay for each day
- Work beyond contracted hours: Where the contract sets the week below 45 hours, the difference is paid at hourly rate × 1.25
How is the hourly rate found?
By the formula monthly gross wage ÷ 225 (30 days × 7.5 hours). The limitation period for overtime claims is five years and runs backwards from the termination.
Proof
The employer's records (timesheets, attendance systems, turnstiles) are taken first. Where there are no records, witness statements, workplace correspondence, vehicle tracking and e-mail times can be used. In the practice of the Court of Cassation, calculations resting on witness evidence in claims of long and regular overtime are usually subject to an equitable reduction.
