Working 22 hrs/week against a 38 hr full-time week is 57.9% of FTE, so a $85,000 full-time salary becomes a pro rata salary of $49,210.53 a year — around $946.36 a week before tax.

Quick answer

Working out a pro rata salary means multiplying the full-time equivalent (FTE) salary by the fraction of full-time hours you actually work: pro rata salary = FTE salary × (your hours ÷ full-time hours). For example, working 22 hours against a 38-hour full-time week on an $85,000 FTE salary gives a pro rata salary of $49,210.53 a year.

How it works

Working out a pro rata salary starts with the full-time equivalent (FTE) salary for the role — what the job pays if worked full-time — then scales it down to match the hours you actually work. This calculator does that scaling for you, so you can see calculating a pro rata salary as a single, transparent step.

Pro rata salary = FTE annual salary × (your hours per week ÷ full-time hours per week)

The standard full-time working week in Australia is 38 hours, the reference point the Fair Work Ombudsman’s minimum wages fact sheet uses when it quotes weekly and hourly minimum pay rates. Most awards and enterprise agreements build their part-time and pro rata provisions around this same 38-hour benchmark, though some roles set a different standard week — always check your award or contract.

Once you have the fraction of full-time hours you work, the same fraction applies to derive the monthly and weekly figures, and to the percentage of full-time employment your role represents:

Percent of FTE = (your hours ÷ full-time hours) × 100
Monthly pro rata pay = pro rata salary ÷ 12
Weekly pro rata pay = pro rata salary ÷ 52

A pro rata salary calculator like this one is useful whenever you’re comparing a part-time offer against a full-time equivalent, negotiating reduced hours, or checking a payslip against your contract.

Worked example

Ravi works as a project coordinator in Brisbane, Queensland, in a role with a full-time equivalent salary of $80,000 and a standard 38-hour week. He’s just moved to a part-time arrangement of two and a half days a week — 19 hours — to study alongside his job.

Working out his pro rata salary: 19 ÷ 38 = 0.5, exactly half of full-time hours. Applying that fraction to his $80,000 FTE salary gives a pro rata salary of $40,000 a year, or $3,333.33 a month and $769.23 a week, before tax. His leave accrual drops to the same 50% rate, so he accrues half the annual and personal leave a full-time colleague in the same role would.

Full-time (38 hrs) Ravi’s part-time (19 hrs)
Percent of FTE 100% 50%
Annual salary $80,000 $40,000
Monthly pay $6,666.67 $3,333.33
Weekly pay $1,538.46 $769.23

Frequently asked questions

What does pro rata mean for a salary in Australia?

Pro rata means 'in proportion' — a pro rata salary is the share of a full-time equivalent (FTE) salary that matches the share of full-time hours you actually work. A part-time employee working half the standard week gets roughly half the FTE salary.

How do I work out my pro rata salary?

Divide your actual weekly hours by the standard full-time week (usually 38 hours), then multiply that fraction by the full-time equivalent annual salary. Working 19 hours against a 38-hour week, for instance, gives exactly 50% of the FTE salary — a calculator does this in one step.

Does pro rata salary include superannuation?

The pro rata salary figure itself is base pay, not including super. Superannuation Guarantee contributions are calculated separately on your ordinary time earnings, including your pro rata salary, at the current statutory rate your employer must pay on top of that base figure.

Is pro rata pay the same for part-time and casual employees?

No. Pro rata applies to part-time employees who accrue paid leave in the same proportion as their hours, while casual employees are paid a loading instead of accruing leave. A casual's hourly rate already factors in the leave a part-time employee gets pro rata.

Is pro rata salary taxed differently to a full-time salary?

No — pro rata salary is taxed under the same individual income tax brackets as any other salary, based on your total taxable income for the year. There's no separate 'part-time' tax scale in Australia; only the dollar amount you earn changes, not the tax rules applied to it.

Does pro rata leave accrue the same way as pro rata salary?

Yes. Annual and personal leave accrue in the same proportion as your hours, so an employee on 50% of full-time hours accrues roughly 50% of the annual leave a full-time employee in the same role would get, prorated across the whole year of service.

What happens to my pro rata salary if my hours change mid-year?

Your salary should be recalculated from the date your hours change, usually paid at the new pro rata rate from your next pay cycle. Ask your employer or check your contract for exactly when the new rate takes effect and how it's applied.
