The ABN vs PAYG comparison uses the same progressive income tax brackets for both scenarios. The difference comes from what gets added or subtracted before and after tax.
PAYG employee calculation
- 1. Gross salary. Your employment contract salary before any deductions — the headline figure.
- 2. Income tax. Applied using 2024–25 resident brackets plus the Low Income Tax Offset (LITO).
- 3. Medicare levy. A flat 2% on incomes above the low-income threshold ($26,000).
- 4. Net take-home. Gross minus tax minus Medicare. Employer super of 11.5% is paid on top of your salary — it does not reduce take-home.
ABN contractor calculation
- 1. Gross revenue. Your invoiced amount — strip GST if your quoted rate includes it, since GST is not income.
- 2. Business expense deductions. Legitimate operating costs (phone, laptop, home office, training) reduce your taxable income before tax is applied.
- 3. Income tax. Applied to revenue minus expenses, using the same 2024–25 brackets as PAYG.
- 4. Medicare levy. The same 2% on taxable income — contractors are not exempt.
- 5. Self-funded super. Contractors must fund their own super. The calculator lets you set the rate to compare apples-to-apples with PAYG.
The hidden costs of contracting
The biggest items PAYG employees receive that contractors do not:
- Annual leave. Four weeks paid leave equals roughly 7.7% of gross salary — contractors must earn enough during working periods to self-fund downtime.
- Sick leave. Ten days per year or about 3.8% of gross salary if fully used.
- Public holidays. Approximately 10 days per year in most Australian states.
- Employer super. 11.5% in 2024–25 — this is not from take-home, it is on top. At $120k salary, that is $13,800/year going into super.
Adding these together, a contractor typically needs to earn 20–30% more than an equivalent PAYG salary just to break even. At a $100,000 equivalent salary, the contractor break-even annual revenue is approximately $125,000–$135,000 before expenses.
What daily rate matches a $100k PAYG salary?
Assuming 48 working weeks, 5 days per week (240 days), a $100,000 PAYG salary is roughly $417/day. But to match the same take-home pay after accounting for missing super (11.5%), leave loadings, and $5,000 in business expenses, you would need approximately $570–$600/day as a contractor. The calculator above shows the exact break-even for your specific inputs.
