How Overtime Pay Is Calculated in Australia
The mechanics of award overtime multipliers — when 1.5× becomes 2×, what counts as ordinary time, and what regular overtime does to your annual pay.
Key Takeaways (FY 2026–27)
- Overtime = hours beyond ordinary time or outside award spread-of-hours rules; multipliers (commonly 1.5× then 2×) come from your award or agreement.
- Weekly Gross = Base Rate × Ordinary Hours + Base Rate × Multiplier × OT Hours.
- Most overtime is excluded from the 12% super guarantee's Ordinary Time Earnings — check your award.
Ordinary Hours vs Overtime Hours
In Australia, ordinary hours are your agreed regular hours — up to 38 per week for full-timers under the NES. Hours worked beyond ordinary time, outside an award's spread-of-hours window, or on weekends/public holidays are overtime and attract penalty multipliers set by your award or enterprise agreement.
A typical award pattern is 150% of the ordinary hourly rate for the first two or three overtime hours, then 200% thereafter — but the exact tiers, daily caps and weekend rules vary. Always check your award's pay guide before relying on any multiplier.
Worked Example: $38/hr Base + 4 Hours at 1.5×
A full-time employee on $38.00/hour works 38 ordinary hours plus 4 overtime hours at time-and-a-half, every week:
- Ordinary pay: $38.00 × 38h = $1,444.00/week
- Overtime pay: $38.00 × 1.5 × 4h = $228.00/week
- Total weekly gross: $1,672.00 → $86,944.00/year
- Estimated FY 2026–27 take-home: $68,601.92/year
The same worker's blended effective rate is $39.81/hour across 42 hours — model your own tiers in the Overtime Pay Calculator.
Tax, Super and Limits on Overtime
Overtime is ordinary assessable income — it stacks on top of your salary and is taxed at your marginal tax rate. A sustained overtime habit can push part of your income into a higher bracket, across the HELP/HECS repayment threshold, or into Medicare Levy Surcharge territory.
For super, the 12% SG applies to Ordinary Time Earnings: distinctly-identifiable overtime payments are generally excluded, so a heavy-overtime year does not lift employer super by the same proportion. Convert any overtime-inclusive annual figure to its hourly equivalent with the Hourly to Salary Calculator to compare against flat-rate offers.
