What is a pro rata salary calculator?
A pro rata salary calculator helps you convert a part-time or casual wage into its full-time equivalent, or adjust a full-time salary for a reduced work week. In Australia, the standard full-time week is 38 hours, so the calculator divides your yearly salary by 52 to get a weekly figure, then by 38 to get an hourly rate. This makes it easy to compare roles with different hours or to check whether your pay meets the relevant award or the national minimum wage.
Our on-site tool does exactly that. You enter a yearly salary before tax, and it returns the weekly and hourly amounts on a 38‑hour week. It also shows the distance from the national full‑time average – the line that defines the site’s benchmark. That average is $2,083.70 a week, or $108,352 a year, based on the ABS Average Weekly Earnings for May 2026.
Why use a pro rata calculator?
If you work 20 hours a week on a $60,000 annual salary, your full-time equivalent is actually $60,000 × (38 ÷ 20) = $114,000. The calculator does this instantly. It also highlights whether your pro-rata rate is above or below the national average, the median, or the minimum wage. For example, the national minimum wage from 1 July 2026 is $26.44 an hour, $1,004.90 a week, or about $52,255 a year on 38 hours. Award minimums rose by 4.75% from that date.
Take-home pay sketch
Because the calculator shows a pre-tax salary, you can estimate your take-home pay using the 2026–27 resident tax rates. The tax-free threshold is $18,200. Above that, you pay 15% on income up to $45,000, 30% up to $135,000, 37% up to $190,000, and 45% on the rest. Add the 2% Medicare levy (some people qualify for a reduction). For a full-time worker on the national average of $108,352, the tax and Medicare levy would be roughly $26,000–$27,000, leaving about $81,000–$82,000 after tax. A part-time worker on a pro-rata salary of $54,176 (half the average) would pay about $8,500 in tax and Medicare, taking home around $45,700.
These are rough sketches. The calculator itself does not deduct tax, but the figures let you apply the brackets yourself. For precise after-tax numbers, use the ATO’s tax estimator.
How the national average is set
The line on this site is the ABS Average Weekly Earnings for full-time adult ordinary-time earnings, May 2026. It is published twice a year (May and November). The current figure is $2,083.70 a week, which we multiply by 52 to get $108,352 a year. This is an average, not a median. The full-time median from the ABS Employee Earnings survey (August 2025) is about $90,532, and the all-employees median is about $74,100. Men’s full-time ordinary-time average is about $113,412; women’s is about $100,594.
State averages also vary. The highest is the Australian Capital Territory at about $119,090, followed by Western Australia at about $115,825. New South Wales is about $109,658, Victoria about $106,137, Queensland about $106,064, South Australia about $102,450, the Northern Territory about $103,173, and Tasmania about $96,008. Place a salary on the line to see how your pro-rata pay compares to these benchmarks.
Pro rata and award minimums
If you are covered by an award, your pro-rata hourly rate must be at least the award minimum for your classification. Fair Work sets the national minimum wage, but many awards have higher rates. From 1 July 2026, award minimums increased by 4.75%. The calculator can help you check whether your offered salary, when converted to an hourly rate, meets that minimum. For example, if your award says $28 an hour and you work 30 hours a week, your weekly pay should be at least $840, or $43,680 a year. The calculator will show the hourly equivalent of your yearly salary, so you can compare directly.
Using the calculator for negotiations
When negotiating a part-time or job-share role, the pro rata salary calculator gives you a clear picture. You can enter the full-time salary for the role, then adjust for your hours. The tool shows the distance from the national average, which is a useful reference point. If the full-time equivalent is below the average, you might argue for a higher rate. If it is above, you know you are being offered a competitive package. States and territories also provide state-specific averages that can be used in local negotiations.
Limitations of the calculator
The tool works with yearly salaries before tax. It does not include superannuation, bonuses, or allowances. It assumes a 38‑hour week, which is the standard for full-time ordinary-time earnings in the ABS series. If your industry or award defines full-time differently (e.g., 40 hours), you can still use the calculator by entering a salary that reflects the correct weekly hours. The distance from the national average will still be valid because the average is based on 38 hours.

Summary
A pro rata salary calculator is essential for anyone working part-time, casually, or in a job-share arrangement. Our tool makes it simple: enter your yearly salary, see your weekly and hourly rate on a 38‑hour week, and check how far you are from the national full‑time average of $108,352. Use the tax brackets to estimate take-home pay, and compare with state averages and medians. Whether you are checking award compliance or negotiating a new role, the pro rata salary calculator puts your pay in perspective.
