Direct answer
Pro rata salary preserves the hourly value of the full-time salary by multiplying it by the part-time hours fraction.
Calculate a part-time Australian salary from a full-time salary and the ratio of part-time to full-time weekly hours.
Use the Australian pay and tax calculator hub to choose the next calculation without repeating the same intent.
Formula and 2026-27 method
Pro rata salary = full-time salary × part-time weekly hours ÷ full-time weekly hours.
The calculation is versioned for the Australian 2026-27 financial year. The result panel keeps the period and source status visible so a value is not detached from the rules that produced it.
To compare this result with another relevant method, open the Australian Hourly to Salary Calculator. Convert an Australian hourly rate to weekly, fortnightly, monthly and annual gross salary with separate ordinary and user-entered overtime pay.
Worked Australian example
AUD 90,000 at 38 hours becomes AUD 56,842.11 at 24 hours per week.
Working precision is retained through the method. Displayed currency is rounded only at the final output unless the ATO payroll schedule itself requires whole-dollar rounding.
How to interpret the result
Main boundary: The result does not automatically calculate leave, allowances, overtime, penalties or award minimum rates.
Keep gross pay, tax liability, payroll withholding, Medicare, study-loan repayments, super and employment entitlements separate. They answer different questions even when they appear on the same payslip.
What this CalculatorGeek version makes explicit
- The exact Australian financial year and effective date.
- The difference between annual tax liability and pay-run withholding where relevant.
- Super paid on top versus included in a package where relevant.
- Formula components, rounding, limitations and source links beside the result.
- Distinct next-step calculators instead of duplicate thin pages for weekly, fortnightly and take-home wording.
