About Overtime Calculator Australia
Overtime Calculator Australia was built to give Australian workers a fast, free way to estimate overtime, public holiday, and Sunday penalty pay, without needing to read through an entire modern award to work out roughly what they’re owed.
We built four simple calculators covering the most common pay situations: ordinary overtime, public holidays, Sunday penalty rates, and straightforward time-and-a-half shifts. Each one takes your base hourly rate and hours worked, and gives you an instant estimate based on common Australian pay rate multipliers (150%, 200%, 225%, and 250%).
These calculators provide general estimates only. Actual pay entitlements depend on your specific modern award, enterprise agreement, or employment contract, and can vary based on factors these simple tools don’t account for, such as classification levels, allowances, and minimum engagement periods. For your exact entitlements, always check the Fair Work Ombudsman website or speak with a payroll professional.
