Salary Sacrifice Calculator Australia | Tax & Super
A salary sacrifice calculator can help Australian employees estimate how redirecting part of their pre-tax salary into superannuation may affect their tax and take-home pay. Salary sacrifice can reduce taxable salary while increasing concessional super contributions.
Using a salary sacrifice calculator makes it easier to compare your income before and after salary sacrifice. You can enter your salary, employer super rate, and proposed contribution to estimate weekly, fortnightly, monthly, and annual changes.
How Salary Sacrifice Works in Australia
What Is Salary Sacrifice?
Salary sacrifice is an arrangement where you give up part of your salary or wages in exchange for an eligible benefit, such as additional superannuation contributions. For super, the sacrificed amount is generally contributed before personal income tax is calculated.
A salary sacrifice calculator can show how changing the amount contributed to super may affect your taxable salary and take-home pay.
How Salary Sacrifice Affects Tax
Salary sacrifice into super can reduce the amount of salary subject to your personal income tax. Concessional super contributions are generally taxed at 15% within the super fund, although additional tax can apply in some circumstances.
The potential benefit depends on your income, contribution amount, employer super contributions, and overall tax position. A salary sacrifice calculator provides an estimate rather than a personal tax assessment.
Use a Salary Sacrifice Calculator
Enter Your Salary Details
To use a salary sacrifice calculator, start with your annual salary and employer super contribution rate. You can then enter the amount you are considering sacrificing into super.
The calculator can estimate your employer contributions and help determine how much concessional contribution capacity may remain after those contributions are considered.
Compare Take-Home Pay
A salary sacrifice calculator can compare estimated take-home pay before and after salary sacrifice. This can help you understand the practical effect on your regular income rather than looking only at the amount contributed to super.
You can compare weekly, fortnightly, monthly, and annual figures to see how a contribution could affect your available cash flow.
Salary Sacrifice and Super Contributions
Understanding the Concessional Cap
Concessional contributions can include employer super contributions, salary sacrifice contributions, and certain personal contributions claimed as a tax deduction. For the 2026–27 financial year, the general concessional contributions cap is $32,500.
A salary sacrifice calculator can help estimate your remaining contribution room by considering employer contributions alongside your planned salary sacrifice amount.
Carry-Forward Contributions
Eligible individuals may be able to use unused concessional contribution amounts from previous financial years. Eligibility generally depends on having a total super balance below $500,000 at the previous 30 June and having unused concessional cap amounts available.
A salary sacrifice calculator can allow eligible carry-forward amounts to be considered when estimating potential contribution capacity.
Benefits of Using a Salary Sacrifice Calculator
Estimate Potential Tax Savings
One of the main reasons to use a salary sacrifice calculator is to estimate the potential difference in personal income tax. Reducing taxable salary may reduce the personal income tax you would otherwise pay, while concessional contributions are generally taxed within super.
The actual benefit depends on your individual circumstances, so calculator results should be treated as estimates rather than guaranteed savings.
Plan Your Take-Home Income
Salary sacrifice can increase the amount directed toward super while reducing the cash income you receive. However, your take-home pay does not necessarily fall by the full amount sacrificed because your personal income tax may also decrease.
A salary sacrifice calculator lets you test different contribution amounts so you can compare the potential super benefit with the reduction in regular take-home pay.
Salary Sacrifice Example
$120,000 Salary Example
For example, an employee earning $120,000 per year could consider sacrificing $10,000 into super. Under the calculator’s simplified 2026–27 example, the taxable salary becomes $110,000 and the estimated personal tax saving is $3,200.
The $10,000 concessional contribution is generally subject to 15% contributions tax, leaving an estimated $8,500 retained in super after that tax.
Compare the Change in Take-Home Pay
In this simplified example, the estimated reduction in take-home pay is approximately $6,800 per year after considering the estimated personal tax saving. That is approximately $131 per week, $262 per fortnight, or $567 per month.
A salary sacrifice calculator makes comparisons like this easier by showing both the amount contributed to super and the estimated change in take-home income.
FAQs
What is a salary sacrifice calculator?
A salary sacrifice calculator estimates how sacrificing part of your salary may affect your taxable income, take-home pay, super contributions, and potential tax savings.
Does salary sacrifice reduce taxable income?
Eligible salary sacrifice contributions to super generally reduce the salary used to calculate personal income tax. The contribution is generally taxed within super instead.

Yes. Some of your salary is redirected into super rather than being paid as cash. However, the reduction in take-home pay may be less than the amount sacrificed because of potential income tax savings.

Your available amount depends on your concessional contribution capacity, including employer super contributions and any eligible carry-forward amounts. For 2026–27, the general concessional cap is $32,500.
Do employer super contributions count toward the concessional cap?
Generally, yes. Employer super contributions count toward the concessional contributions cap along with salary sacrifice and certain other concessional contributions.
