Salary Sacrifice Calculator
Compare your 2026-27 tax with and without salary sacrificing to super, and see what each dollar of take-home pay you give up actually buys in retirement savings.
Is salary sacrifice worth it?
Yes from the 30% bracket up. Below it, barely. The sacrificed dollars are taxed at 15% inside your super fund instead of at your marginal rate, and the gap between those two numbers is the entire return. On $80,000 in 2026-27, sacrificing $10,000 cuts tax and Medicare by $3,200, drops take-home pay by $6,800 and puts $8,500 into the fund. You are $1,700 better off in total, with the catch that the gain is locked away until you meet a condition of release.
| Salary | Tax + Medicare saved | Take-home given up | Into super | Ahead by |
|---|---|---|---|---|
| $50,000 | $2,775 | $7,225 | $8,500 | $1,275 |
| $80,000 | $3,200 | $6,800 | $8,500 | $1,700 |
| $150,000 | $3,900 | $6,100 | $8,500 | $2,400 |
| $200,000 | $4,700 | $5,300 | $8,500 | $3,200 |
$10,000 sacrificed, 2026-27 resident rates, tax-free threshold claimed, no study loan. Every figure is computed by the same engine that runs the calculator below.
Read the last column as cents in the dollar and the pattern is plain. At $80,000 you keep 17c of every sacrificed dollar after the fund's $1,500 bite; at $200,000 you keep 32c. Go the other way and it collapses: at $45,000 the same $10,000 saves only $2,076 of tax, against $1,500 of contributions tax, so under 6c in the dollar survives. Sacrificing on a 15% marginal rate is close to moving money from one pocket to another and losing access to it.
The $200,000 row is arithmetic, not a recommendation, because the cap bites there first. Employer SG at 12% of $200,000 is $24,000 for 2026-27, and SG counts toward the same $32,500 concessional cap as your sacrifice, leaving $8,500 of room. Sacrifice the full $10,000 on that salary and you are over the cap. Above $250,000 of income plus concessional contributions, Division 293 tax takes another 15% and the 32c drops to 17c.
Two things salary sacrifice does not do, whatever your bracket. It does not shrink your HELP repayment, because the ATO adds reportable super contributions straight back into repayment income. And it does not give you the money back if the car dies or the roof leaks. Run your own figures below before you sign a sacrifice agreement with payroll.
- Sacrificed amounts are taxed at 15% inside the fund instead of your marginal rate, which is where the saving comes from.
- The 2026-27 concessional cap is $32,500. Employer SG and your sacrifice both count towards it.
| Line | No sacrifice | With sacrifice |
|---|---|---|
| Taxable income | $100,000 | $90,000 |
| Income tax + Medicare | $22,520 | $19,320 |
| Take-home pay | $77,480 | $70,680 |
| Extra into super | $8,500 |
Resident rates for 2026-27 with the tax-free threshold claimed. Assumes your employer keeps paying SG on your pre-sacrifice salary. Sacrificed super is a reportable super contribution, so it does not reduce HELP repayment income.
How salary sacrifice saves tax
You agree with your employer to take less salary and have the difference paid into super before tax ever touches it. Sacrifice $10,000 from a $100,000 salary and your taxable income drops to $90,000: tax and Medicare fall by $3,200, take-home pay falls by $6,800, and $8,500 lands in your fund after the 15% contributions tax. Giving up $6,800 of spending money to bank $8,500 is the whole pitch in one sentence. This tool sits alongside the rest of our tax calculators if you want the full pay picture.
The saving scales with your marginal rate under the 2026-27 tax brackets. The same $10,000 sacrifice saves $3,200 in the 30% bracket but $4,700 in the top bracket, because the sacrificed dollars would otherwise have been taxed at 45% plus the Medicare levy. In the 15% bracket the arithmetic barely moves: the fund pays 15% anyway, so the arrangement earns its keep from the 30% bracket up.
Above $250,000, Division 293 tax cuts the benefit roughly in half. If your income plus your concessional contributions passes $250,000, the ATO charges an extra 15% on those contributions, taking the effective rate on them to 30% for 2026-27 rather than 15%. The extra is charged on the lesser of the amount over the threshold or your taxable contributions, so it only bites in full once you are well past the threshold. At a 47% marginal rate each sacrificed dollar then nets 17c instead of 32c. The threshold has sat at $250,000 since 2017-18, and the ATO works the tax out from your tax return and the contributions your fund reports.
Salary packaging vs salary sacrifice
The two terms get used interchangeably, but packaging is the umbrella. Salary packaging means paying for anything out of pre-tax salary: super, cars, laptops, or living expenses if you work for a charity or public hospital. Salary sacrificing to super is the specific arrangement this page calculates, and it is the simplest of the lot because super has its own flat 15% contributions tax.
Packaged cars and other benefits work differently: they can attract fringe benefits tax through your employer and show up on your income statement as reportable fringe benefits. If a car is the benefit you are weighing up, the novated lease tax calculator models that pre-tax deduction instead.
Watch-outs before you sign the form
Worth checking first
- The $32,500 concessional cap for 2026-27 counts employer SG plus your sacrifice together
- Confirm with payroll that your 12% SG stays based on your pre-sacrifice salary
- Sacrifice agreements only work on future salary, so set them up before the pay period starts
What sacrifice does not do
- It does not cut your HELP repayment: sacrificed super is added back to repayment income
- It does not give you access to the money; super stays locked away until a condition of release
- It does not escape tax entirely; the fund still deducts 15% on the way in, and Division 293 adds another 15% above $250,000
The HELP add-back trips people up every year. If you carry a study loan, run your pre-sacrifice income through the HECS repayment calculator to see the repayment that still applies. To estimate the employer SG side of your cap, use the super guarantee calculator. Sacrifice is one of four lawful levers on the amount withheld from your pay, and how to reduce PAYG tax covers the other three plus the schemes that do not survive contact with the ATO.
