Salary sacrifice novated lease calculator: How awards and the national minimum wage affect your figures

What is a salary sacrifice novated lease calculator?

A salary sacrifice novated lease calculator is a tool that estimates the net cost or saving of leasing a car through your employer. You agree to forgo part of your pre-tax salary in exchange for the employer covering the lease payments, running costs, and fringe benefits tax (FBT). The calculator works out your reduced taxable income, the tax you save, and any FBT liability. It then shows your take-home pay after the arrangement.

This article explains how the calculator interacts with Australia’s award system and the national minimum wage. The angle is awards versus the national minimum wage, because your base salary must stay above the relevant minimum. If you are on an award, your salary sacrifice cannot push your ordinary-time earnings below the award rate.

The national minimum wage and award rates

The national minimum wage from 1 July 2026 is $26.44 per hour, $1,004.90 per week, or $52,255 per year. On the Salary Index, that is index 48.2 – meaning it is about half of the full-time adult ordinary-time earnings benchmark of $108,352 per year (index 100).

Award rates are higher. For example, the retail trade industry has an index of 75.9, and accommodation and food services sits at 72.5. Professional, scientific and technical services is 114.7. The exact award classification depends on your role, experience, and location. The Fair Work Ombudsman publishes pay guides for each award. You can find them on the pay guides page.

When you use a salary sacrifice novated lease calculator, you need to enter your gross salary. If you are on an award, the calculator should check that your salary after sacrifice does not fall below the award minimum. Otherwise, the arrangement is not allowed.

How the calculator uses your salary

A typical salary sacrifice novated lease calculator asks for:

• Your gross annual salary
• Your pay frequency
• Your tax file number declaration (for withholding)
• The lease term and car cost
• Estimated running costs (fuel, insurance, maintenance)
• FBT method (statutory formula or operating cost)

It then estimates your taxable income after the sacrifice, the income tax you save, and any FBT payable. It also shows the impact on your super guarantee. From 1 July 2026, the super guarantee is 12% of your ordinary-time earnings, up to a maximum contribution base of $270,830. If your salary sacrifice reduces your ordinary-time earnings, your employer’s super contribution may also fall.

For example, suppose you earn $80,000 per year. That is index 73.8 – below the national average but above the national minimum wage. You want to salary sacrifice $15,000 for a novated lease. The calculator reduces your taxable income to $65,000. Your income tax (2026–27 rates, excluding Medicare) drops from about $16,567 to $11,767, saving $4,800. But you also pay FBT on the car benefit. The calculator estimates the FBT and deducts it from your take-home pay. The net result might be a saving of a few thousand dollars, depending on the car’s cost and how much you drive for work.

Awards set a floor for salary sacrifice

If you are covered by a modern award, your base rate of pay cannot be reduced below the award minimum. The Fair Work Ombudsman states that salary sacrifice arrangements must not result in you receiving less than the award rate for the hours you work. The calculator should warn you if your proposed sacrifice would breach that floor.

For instance, a hospitality worker on the Restaurant Industry Award might have a minimum hourly rate of $28.50 (example only – check the actual award). If they work 38 hours per week, their weekly minimum is $1,083. Their annual salary must be at least $56,316. If they try to salary sacrifice $10,000 from a $60,000 salary, the remaining $50,000 is below the award floor. The calculator would flag that as invalid.

State and industry differences

Your location also matters. The states page shows that the ACT has the highest index at 109.9, while Tasmania is lowest at 88.6. A salary sacrifice novated lease calculator may incorporate state tax rates (though payroll tax is employer-paid) and any state-specific FBT exemptions. For example, electric vehicles may have FBT exemptions that the calculator can apply.

Industry matters too. Mining has an index of 154.7 – well above average. A miner on $160,000 can salary sacrifice a larger amount and still stay above the award rate (if any) and the national minimum wage. The calculator will show higher tax savings because they are in the 37% or 45% tax bracket.

How the salary index fits in

The how the index works page explains that the index is your gross yearly salary divided by the national line ($108,352) times 100. A salary sacrifice novated lease calculator can use the index to give you a quick sense of where you sit. If your index is below 100, you are below the average full-time earner. If it is above, you are above average. The calculator might show your index before and after the sacrifice.

For example, a teacher on $95,000 has an index of 87.7. After sacrificing $15,000, their index drops to 73.8. That is still above the national minimum wage index of 48.2, but it is below the education and training industry average of 105.5. The calculator can help you decide whether the trade-off is worth it.

Tax and super considerations

The calculator uses the resident tax rates for 2026–27: 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; 45% above $190,000. Medicare levy is 2% flat. The calculator ignores HELP repayments, the Medicare levy reduction, and the Medicare levy surcharge, so your actual take-home may differ.

Super guarantee is 12% on your ordinary-time earnings. If your salary sacrifice reduces your ordinary-time earnings, your employer pays less super. The calculator should show the reduced super contribution. You can then decide whether to make personal contributions to make up the difference.

Common questions about salary sacrifice novated lease calculators

Can I salary sacrifice if I'm on the national minimum wage?

If you earn exactly the national minimum wage ($52,255 per year), your index is 48.2. You cannot salary sacrifice because your pay is already at the minimum. Any reduction would breach the Fair Work Act. The calculator would not allow it.

Does the calculator account for FBT?

Yes, a proper calculator includes FBT. The statutory formula method is common: 20% of the car’s cost multiplied by the number of days available, then grossed up by the FBT rate (47% for 2026–27). The calculator subtracts the FBT from your tax savings.

Where can I find my award rate?

Check the Fair Work Ombudsman website or use the pay guides on Salary Index. Your employer must also tell you which award applies.

Final thoughts

A salary sacrifice novated lease calculator is a useful tool, but only if you understand the award and minimum wage rules. Your base salary must stay above the relevant minimum. Use the calculator to model different scenarios, and always check with your employer or a tax professional before signing. The topics page has more on salary packaging and fringe benefits.

Remember, the figures in this article are based on the national line of $108,352 per year (index 100) from the Australian Bureau of Statistics. Your own situation may vary.
