Understanding Salary Sacrifice and the National Average
Salary sacrifice is an arrangement where you agree to reduce your pre-tax salary in exchange for benefits such as additional superannuation contributions. The amount sacrificed is not subject to income tax (though it is taxed in the super fund), so it lowers your taxable income. This can affect how your pay compares to the national full-time average, which is based on ordinary-time earnings before any sacrifice.
The national full-time adult ordinary-time average is $2083.70 a week, or about $108,352 a year (ABS Average Weekly Earnings, May 2026, multiplied by 52). This is the reference line used on this site. When you use a salary sacrifice superannuation calculator, you enter your yearly salary before tax, and the tool shows your weekly and hourly pay on a 38-hour week, plus the distance from this average.
How Salary Sacrifice Changes Your Take-Home Pay
Your take-home pay is what remains after income tax and the Medicare levy are deducted from your taxable income. Salary sacrifice reduces your taxable income, so you pay less tax. However, the sacrificed amount goes into your super fund, where it is generally taxed at 15% (the concessional contributions tax). The net effect is that your take-home pay decreases by less than the sacrificed amount because you save on marginal tax.
For example, if you earn $108,352 (the national average) and sacrifice $10,000 into super, your taxable income becomes $98,352. Using the 2026–27 resident tax rates (nil to $18,200; 15% to $45,000; 30% to $135,000; 37% to $190,000; 45% above that) plus the 2% Medicare levy, the tax saving is roughly the difference between your marginal rate and the 15% contributions tax. The calculator on this site can show the exact weekly and hourly figures.
Comparing Your Sacrificed Salary to the Averages and Medians
It is important to distinguish between averages and medians. The national full-time average of $108,352 is an arithmetic mean of full-time ordinary-time earnings. The full-time median is about $90,532 (ABS Employee Earnings, August 2025), meaning half of full-time workers earn less and half earn more. The all-employees median is about $74,100. The national minimum wage from 1 July 2026 is $26.44 an hour, $1004.90 a week, or about $52,255 a year on 38 hours.
If you salary sacrifice, your reported salary for comparison is the reduced amount. For instance, if you earn $120,000 and sacrifice $15,000, your taxable income is $105,000, which is below the national average. But your total remuneration (salary plus super contributions) may be higher. The calculator shows your pay against the average based on the sacrificed salary.
State-by-State Averages and Salary Sacrifice
State full-time averages vary. For example, the Australian Capital Territory has the highest average at about $119,090, while Tasmania has the lowest at about $96,008. If you live in a high-average state like Western Australia ($115,825) or New South Wales ($109,658), salary sacrifice might bring your taxable income closer to or below the state average. The States and territories page provides more detail on regional differences.
Using the Calculator on This Site
The on-site tool accepts a yearly salary before tax. It shows a week and an hour on a 38-hour week, plus distance from the full-time average. You can enter your salary after sacrifice to see where you stand. For a more detailed breakdown of how the figures are set, see How the figures are set.
Tax Considerations for Salary Sacrifice
The ATO sets the concessional contributions cap (currently $30,000 per year, but check for updates). Amounts above the cap are taxed at your marginal rate. Salary sacrifice is most beneficial if your marginal tax rate is above 15% (i.e., taxable income over $45,000). For those earning below $45,000, the tax saving is smaller or nil. The Medicare levy of 2% applies to most residents, but low-income earners may receive reductions.
Practical Example
Suppose you earn $130,000 and sacrifice $20,000 into super. Your taxable income becomes $110,000. The tax on $110,000 (using 2026–27 rates) is approximately $24,867 plus Medicare levy of $2,200, total $27,067. Without sacrifice, tax on $130,000 would be about $31,467 plus $2,600 Medicare, total $34,067. You save $7,000 in tax, but the $20,000 in super is taxed at 15% ($3,000), so net benefit is $4,000. Your take-home pay reduces by $20,000 minus the tax saving of $7,000, i.e., $13,000 less per year. The calculator will show your new weekly and hourly pay.
Conclusion
A salary sacrifice superannuation calculator helps you understand the trade-off between lower take-home pay and higher superannuation savings. By comparing your sacrificed salary to the national full-time average of $108,352, you can see where you sit relative to the typical full-time worker. Remember that the average is based on earnings before sacrifice, so your reported salary may be lower even if your total package is competitive.
