Australian Timesheet and Overtime Calculator
This calculator helps Australian employees and employers accurately compute total hours worked, break deductions, and overtime pay. It applies the rules commonly found in modern awards and enterprise agreements, using your ordinary hours and penalty rates to determine your gross pay for a pay period.
How Overtime is Calculated in Australia
Overtime pay is generally required when an employee works beyond their ordinary hours of work. Ordinary hours are the standard, non-overtime hours as defined in your award, registered agreement, or contract. They are usually capped per day and per week.
The calculation follows these steps:
- Net Hours Worked: Start with your total clocked hours and subtract any unpaid break time.
- Ordinary Hours Limit: Determine your maximum ordinary hours for the period. This is typically the lesser of: (Ordinary Hours per Day × Days Worked) or the (Ordinary Hours per Week).
- Ordinary Hours Payable: The portion of your net hours that falls within this limit is paid at your base hourly rate.
- Overtime Hours: Any net hours worked beyond the ordinary hours limit are considered overtime.
- Overtime Tiers: Overtime is often paid at increasing penalty rates. A common structure is time-and-a-half (150%) for the first 2 hours of overtime, and double time (200%) for any overtime thereafter. You can configure these rates and thresholds in the calculator.
- Total Gross Pay: Sum the ordinary pay and the overtime pay at the different rates.
Example Calculation
Consider a full-time employee covered by an award with a 38-hour week and 7.6-hour standard day. Their hourly rate is $30. They worked 10 days in a fortnight, clocking 85 total hours with 5 hours (300 minutes) of unpaid breaks. Their award stipulates time-and-a-half for the first 2 hours of overtime and double time thereafter.
- Net Hours = 85 - (300/60) = 80 hours.
- Ordinary Hours Limit = min(7.6 × 10, 38) = min(76, 38) = 38 hours.
- Ordinary Hours Payable = 38 hours.
- Total Overtime = 80 - 38 = 42 hours.
- Overtime at 150% = min(42, 2) = 2 hours.
- Overtime at 200% = 42 - 2 = 40 hours.
- Ordinary Pay = 38 × $30 = $1,140.
- Overtime Pay (150%) = 2 × $30 × 1.5 = $90.
- Overtime Pay (200%) = 40 × $30 × 2.0 = $2,400.
- Total Gross Pay = $1,140 + $90 + $2,400 = $3,630.
Common Scenarios
Part-time Employees: Have lower ordinary hour thresholds (e.g., 20 hours per week). Overtime only applies once they exceed their agreed-upon part-time hours.
Casual Employees: Typically receive a casual loading (e.g., 25%) on their hourly rate instead of paid leave entitlements. Overtime may still apply on top of this loading if they exceed the award's maximum hours.
Shift Workers: May have different ordinary hour spans and may be entitled to shift penalties in addition to, or instead of, overtime.
Next Steps: Document Your Hours
After calculating your pay, it's important to formally record your hours. Using a Time Sheet ensures an accurate record for payroll processing and compliance. Our Time Sheet template is designed for Australian businesses and includes fields for employee details, daily start/finish times, breaks, total hours, overtime, and supervisor approval.
