Overtime Calculator Australia
Our free overtime calculator helps Australian workers quickly estimate their take-home pay for any shift type. Simply enter your hourly rate, hours worked, employment type, and the day of the week — and see an instant breakdown of ordinary pay, overtime tiers, penalty rates, and casual loading all in one place.
Whether you're a full-time employee checking your Sunday shift, a casual worker on a public holiday, or a part-timer wanting to understand your entitlements, this tool makes the maths simple and transparent.
How Overtime Works in Australia
Under the National Employment Standards (NES), most full-time employees have a maximum ordinary hours working week of 38 hours. Hours beyond this threshold are considered overtime and are typically paid at a higher rate.
Key things to know:
- Ordinary hours: Usually the first 38 hours per week, or the first 8 hours per day, depending on your award or enterprise agreement.
- Daily overtime thresholds: Many awards set a daily trigger (commonly 8 hours) after which overtime rates apply, even if you haven't exceeded 38 hours for the week.
- Award differences: The overtime rules can vary significantly across different Modern Awards. Always check your specific award or consult the Fair Work Commission.
Overtime is commonly paid at 150% (time and a half) for the first two hours and 200% (double time) for subsequent hours, though this varies by award.
What Are Penalty Rates?
Penalty rates are higher pay rates that apply when employees work at certain times, including weekends and public holidays. They compensate workers for the inconvenience of working during times that most people have off.
- Saturday penalty rates — commonly 150% of the ordinary rate
- Sunday penalty rates — typically 200% of the ordinary rate
- Public holiday rates — usually 250% of the ordinary rate (double time and a half)
These rates differ between industries and awards. For example, retail workers, hospitality staff, and healthcare workers often have unique penalty rate structures. Use the Advanced Settings panel above to customise the multipliers to match your specific award.
Casual Loading Explained
Casual employees in Australia receive a casual loading — an extra percentage added to their base hourly rate — to compensate for the lack of paid leave entitlements (such as annual leave and sick leave) that permanent employees receive.
The standard casual loading is 25% of the ordinary hourly rate, as set by the Fair Work Act. This means a casual worker earning a base rate of $30/hr receives an adjusted rate of $37.50/hr before any overtime or penalty rate calculations.
Some awards and enterprise agreements set different casual loading percentages. You can adjust this value in the Advanced Settings of our calculator.
Why Your Pay May Differ
This calculator provides a useful general estimate, but your actual pay may differ due to several factors:
- Modern Awards: Most Australian workers are covered by a specific Modern Award that sets minimum pay rates, overtime rules, and penalty rates for their industry or occupation.
- Enterprise Agreements: Some workplaces operate under enterprise agreements (EAs) negotiated between employers and employees, which may provide different conditions to the relevant award.
- Individual Contracts: If your employment contract sets rates above the award minimum, those rates will apply instead.
- State and Territory variations: Certain industries in some states may have specific provisions.
