How to Calculate Take Home Pay Using the Australian Salary Index
Learn how to calculate take home pay from your salary index figure. Estimate net income after tax and Medicare levy using our guide.
The salary index compares gross annual earnings to the national line of $108,352 (index 100). To calculate take home pay, apply the resident tax rates and Medicare levy to your gross figure.
Understanding the Salary Index and Take Home Pay
When you see a salary index figure on Salary Index, it represents how your gross annual earnings compare to the national benchmark. The national line is set at 100, which corresponds to full-time adult ordinary-time earnings of $108,352 per year (based on the Australian Bureau of Statistics Average Weekly Earnings, May 2026). If your index is 120, your gross salary is 20% above that benchmark. But what you actually take home after tax and the Medicare levy is a different number. This guide explains how to calculate take home pay from your salary index.
What the Salary Index Measures
The index is a simple ratio: your yearly gross salary divided by the national line, multiplied by 100. For example, if you earn $130,000 a year, your index is approximately 120 (130,000 ÷ 108,352 × 100). The index is a benchmark for comparing pay across industries and states. For instance, the mining industry has an index of 154.7, while retail trade sits at 75.9. You can explore these differences on our industries page. The index does not include superannuation, bonuses, or overtime—it is purely ordinary-time earnings.
Step-by-Step: From Index to Take Home Pay
To calculate take home pay, you first need your gross annual salary. If you only know your index, multiply it by $108,352 and divide by 100. For example, an index of 110 gives gross earnings of $119,187.20. Next, apply the 2026–27 resident tax rates and the 2% Medicare levy.
Tax Calculation Example
Take a gross salary of $119,187 (index 110). Using the tax brackets:
- 0% on first $18,200: $0
- 15% on $18,201 to $45,000 ($26,800): $4,020
- 30% on $45,001 to $135,000 ($74,187): $22,256.10
- Total tax before Medicare: $26,276.10
- Medicare levy (2% of $119,187): $2,383.74
- Total deductions: $28,659.84
- Estimated annual take home pay: $119,187 – $28,660 = $90,527
This is a resident estimate using the tax-free threshold. It ignores HELP repayments, salary sacrifice, and the Medicare levy surcharge. For a more precise figure, use the ATO’s tax calculator or speak to a tax professional.
How State and Industry Affect Your Index
Your take home pay depends on your gross salary, but the index can vary significantly by location and industry. For example, the ACT has an index of 109.9 (annualised $119,090), while Tasmania is at 88.6 ($96,008). Even if two people have the same index, their take home pay will be identical if they have the same gross salary and tax situation. However, the index helps you see where your earnings sit relative to the national average. Check our states page for more details.
The Role of Awards and Minimum Wage
If you are paid under a modern award or the national minimum wage, your gross salary may be lower than the index suggests for your role. The national minimum wage from 1 July 2026 is $26.44 per hour, or $52,255 per year (index 48.2). Award minima rose by 4.75% from the same date. For example, an entry-level award floor is $25.74 per hour. These rates are the legal minimum; many employers pay above award. When calculating take home pay from an award rate, multiply your hourly rate by hours worked per week and then by 52 weeks. The pay guides section can help you understand award classifications.
Superannuation and Take Home Pay
Superannuation is not part of your take home pay. The super guarantee is 12% from 1 July 2026, but it is paid by your employer into a super fund and is not accessible until retirement. Your salary index is based on gross earnings before super. So if your contract says $100,000 plus super, your index is calculated on $100,000, not $112,000. When calculating take home pay, ignore the super amount.
Common Pitfalls in Take Home Pay Calculations
- Ignoring the Medicare levy: It is a flat 2% on taxable income. Do not forget to include it.
- Using the wrong tax rates: The 2026–27 rates are current. Older rates may give incorrect results.
- Forgetting the tax-free threshold: The first $18,200 is tax-free. If you have multiple jobs or are a non-resident, different rules apply.
- Overlooking HELP or HECS debts: If you have a student loan, an additional repayment is withheld (typically 1% to 10% of income). This is not included in our basic estimate.

Why Use the Salary Index for Take Home Pay?
The salary index gives you a quick way to compare your gross earnings to a national benchmark. By converting that index to a dollar figure and applying tax rules, you can estimate your take home pay. This is useful when evaluating job offers, negotiating salaries, or planning your budget. Remember that the index is a gross figure—your actual take home will always be lower due to tax and Medicare. Use the example above as a starting point, and adjust for your personal circumstances.
Questions people ask
How do I calculate take home pay from my salary index?
First convert your salary index to gross annual earnings: multiply the index by $108,352 and divide by 100. Then apply the 2026–27 resident tax rates: nil up to $18,200, 15% from $18,201 to $45,000, 30% from $45,001 to $135,000, 37% from $135,001 to $190,000, and 45% above $190,000. Add the 2% Medicare levy. Subtract the total tax and levy from your gross earnings to estimate your annual take home pay. This estimate ignores HELP repayments, salary sacrifice, and the Medicare levy surcharge.
What tax rates apply when calculating take home pay?
For the 2026–27 income year, resident tax rates are: 0% on the first $18,200, 15% on income between $18,201 and $45,000, 30% between $45,001 and $135,000, 37% between $135,001 and $190,000, and 45% on income above $190,000. The Medicare levy is a flat 2% on taxable income. These rates are used to estimate take home pay, but individual circumstances such as the Medicare levy surcharge, HELP debt, or tax offsets can change the final amount.
Does the salary index include superannuation?
No. The salary index is based on gross ordinary-time earnings before superannuation. The super guarantee is 12% from 1 July 2026, but it is paid on top of the base salary and is not included in the index figure. When calculating take home pay, you only consider the gross salary, not the super contribution, because super is not available as cash income until retirement.
