Salary Sacrifice Novated Lease Calculator ATO: How State and Industry Pay Differences Affect Your Savings

What is a salary sacrifice novated lease calculator from the ATO?

A salary sacrifice novated lease is an arrangement where your employer pays for a car lease and running costs from your pre-tax salary. The ATO provides guidelines and a calculator to help you estimate the net benefit after tax and Fringe Benefits Tax (FBT). The calculator uses your gross salary, marginal tax rate, and lease details to show how much you could save compared to paying from after-tax income.

On Salary Index, we measure gross ordinary-time earnings against a national benchmark of 100. That benchmark is $108,352 per year (based on ABS Average Weekly Earnings). Your own index figure is your yearly gross divided by that line, times 100. Understanding where your pay sits on this index helps you assess whether a novated lease is worthwhile, because higher gross pay means a higher marginal tax rate and potentially larger savings from salary sacrifice.

How state pay differences affect your novated lease calculation

State pay indices vary across Australia. For example, the ACT has an index of 109.9 (annualised $119,090), while Tasmania sits at 88.6 ($96,008). If you work in a state with a higher index, your gross pay is likely higher, which pushes you into a higher tax bracket. That makes salary sacrifice more attractive because you save tax at a higher rate on the sacrificed amount.

Consider a worker in Western Australia (index 106.9, $115,825 annualised) versus one in South Australia (index 94.6, $102,450). The WA worker on a typical professional salary may be in the 37% tax bracket (plus 2% Medicare levy), while the SA worker might be in the 30% bracket. Using the ATO salary sacrifice novated lease calculator, the WA worker would save more tax per dollar sacrificed. However, you also need to account for FBT, which applies if private use of the car exceeds the statutory threshold. The calculator handles that.

State indices are a starting point. Your actual pay depends on your award, enterprise agreement, or individual contract. For a more precise comparison, see our states page for detailed breakdowns.

How industry pay differences affect your novated lease calculation

Industry indices show even wider gaps. Mining has an index of 154.7, while Accommodation and food services is 72.5. A mining engineer earning well above the national line will have a high marginal tax rate, making salary sacrifice very beneficial. In contrast, a hospitality worker on award wages may have a lower tax rate and less to gain.

For example, a professional in the Professional, scientific and technical services industry (index 114.7) earning around $124,000 annually would be in the 37% tax bracket. Sacrificing $15,000 for a novated lease could save about $5,550 in tax plus Medicare levy (assuming no FBT exemption). But a retail worker (index 75.9) earning $82,000 might only save around $3,600 at the 30% rate. The ATO calculator accounts for these differences.

Industry pay also influences your ability to afford the lease payments. Higher-index industries tend to have higher super contributions (12% from July 2026) and better conditions, but that doesn't directly affect the lease calculation. For more on industry benchmarks, visit our industries page.

Using the salary index to estimate your novated lease benefit

To use the salary index effectively with a novated lease, first find your gross annual salary. Divide it by $108,352 and multiply by 100 to get your index. Then use that index to see how you compare to the national line. Next, input your gross salary into the ATO salary sacrifice novated lease calculator along with the lease cost and running expenses. The calculator will show your net benefit.

Remember, the index is a gross benchmark. Salary sacrifice reduces your taxable income but does not change your index figure. Your index remains based on your full gross earnings before sacrifice. That's important when comparing roles or negotiating pay.

Practical example: comparing two workers

Let's take two hypothetical workers using the ATO calculator. Worker A in the ACT (index 109.9) in the Professional services industry (index 114.7) earning $130,000 gross. Worker B in Tasmania (index 88.6) in Retail trade (index 75.9) earning $80,000 gross. Both consider a novated lease of $12,000 per year.

Worker A is in the 37% tax bracket (plus 2% Medicare). The tax saved on $12,000 is $4,680. After FBT (if applicable) and GST credits, the net saving might be around $3,500. Worker B is in the 30% bracket, saving $3,600 in tax, but after FBT the net saving might be $2,500. The difference is driven by the higher index and tax bracket.

This example shows why understanding your state and industry index matters. It helps you gauge whether a novated lease is likely to be beneficial before you run the full calculator.

Key considerations from the ATO

The ATO's salary sacrifice novated lease calculator requires accurate inputs: your gross salary, the car's cost, lease term, estimated running costs, and your expected private use percentage. The calculator then estimates FBT using the statutory formula method (20% of the car's base value for most cars). It also accounts for GST credits available on the lease and running costs.

Your employer must agree to the salary sacrifice arrangement. Some employers limit the amount you can sacrifice, and some awards or enterprise agreements may restrict salary sacrifice. Check your contract and consult the Fair Work Ombudsman if unsure.

Super guarantee contributions are calculated on your ordinary-time earnings, which may be reduced by salary sacrifice. However, the ATO allows you to sacrifice into super separately. The calculator does not adjust for super, so you need to consider that separately.

Final thoughts

The salary sacrifice novated lease calculator from the ATO is a practical tool for Australian workers. By combining it with the salary index, you can see how your state and industry pay level affects the potential savings. Higher-index states and industries generally offer greater tax benefits, but your individual circumstances matter most.
