Australia Overtime pay calculator

Work out your overtime pay and total weekly earnings — time-and-a-half, double time, or any premium rate — plus your blended hourly rate and what the extra hours add up to over a year.

Extra from overtime / week

The overtime premium adds $100.00 a week beyond your base rate — about $5,200.00 a year if you keep these hours up. That premium is the part you'd lose by working the same hours at straight time.

Figures are gross (before income tax and any payroll deductions). Overtime is usually taxed at your normal marginal rate — it isn't taxed at a special higher rate, though a bigger paycheque can push more of your income into a higher bracket. This is an estimate, not pay or legal advice.

How overtime pay works in Australia

In Australia, overtime and penalty rates are set by modern awards and enterprise agreements — and they're often generous. A typical award pays time-and-a-half (1.5×) for the first 2–3 overtime hours and double time (2×) thereafter, with double time (or more) for Sundays and public holidays. Your exact entitlement depends on the award covering your job.

Overtime pay = base rate × award multiplier × overtime hours

Worked example

At $25/hour, 40 regular hours plus 8 hours where the award pays double time: regular pay is $1,000, the overtime rate is $50, and overtime pay is 8 × $50 = $400, for a $1,400 week. Use the double-time field for hours your award pays at 2×.

Penalty rates and awards

Beyond overtime, awards set penalty rates for evenings, weekends, and public holidays, plus shift loadings. Award-free, salaried, or high-income employees may have overtime "rolled up" into their salary instead — check whether your contract absorbs it. The Fair Work Ombudsman's Pay Calculator confirms the rates in your award.

How overtime is taxed

Overtime is ordinary income taxed at your marginal rate, with the 2% Medicare levy on top. The ATO's Schedule 5 can make withholding on a lump of overtime look high on the payslip, but it squares up at tax time. Overtime also counts toward your ordinary time earnings only in limited cases, so it may not attract the 11.5% super guarantee — check your payslip.

Frequently asked questions

How is overtime pay calculated?
Multiply your base hourly rate by the overtime multiplier to get the overtime rate, then multiply that by your overtime hours. At a base rate of 25 with time-and-a-half, the overtime rate is 25 × 1.5 = 37.50 per hour. Your total pay is your regular hours at the base rate plus your overtime hours at the overtime rate.
What is time-and-a-half and double time?
Time-and-a-half means 1.5× your base rate — the most common overtime premium. Double time means 2× your base rate, often paid for public holidays, very long shifts, or a seventh consecutive working day. The calculator lets you set a primary overtime multiplier and add separate double-time hours.
Is overtime taxed at a higher rate?
No. Overtime is ordinary income taxed at your normal marginal rate — there's no special overtime tax. What can happen is that a larger paycheck triggers higher tax withholding for that pay period, or pushes more of your annual income into a higher tax band. Over a full year it evens out to your true marginal rate.
What is a blended or effective hourly rate?
It's your total pay divided by your total hours worked, including overtime. Because the overtime premium is spread across every hour, the blended rate sits between your base rate and your overtime rate. It's a quick way to see what each hour of your week is really worth once the premium is averaged in.
Am I entitled to overtime pay?
It depends on where you work and your employment terms. Some countries mandate an overtime premium by law (for example, time-and-a-half over a set weekly threshold), while in others it's set by your contract, award, or agreement and isn't guaranteed. Salaried or 'exempt' roles may not receive paid overtime at all — check your contract or local employment standards.
Does overtime count toward holiday pay or pension?
Sometimes. In several systems, regular overtime should be included when calculating holiday pay, and it may or may not attract pension or retirement contributions depending on local rules and whether it counts as ordinary earnings. Because this varies by country and employer, check your payslip and local guidance — this calculator shows gross overtime pay only.
