How the Smart Salary Novated Lease Calculator Affects Your Gross Pay and Tax
Learn how the smart salary novated lease calculator estimates tax savings and lease costs, and how it relates to your gross pay, super, and the national salary index.
The calculator doesn't set your pay, but your gross pay index (100 = full-time adult ordinary-time earnings) determines potential tax savings; typical full-time earnings are around index 100.
What is a novated lease and how does the smart salary novated lease calculator work?
A novated lease is a three-way arrangement between you, your employer, and a finance company. Your employer deducts lease payments from your pre-tax salary, which can lower your taxable income. The smart salary novated lease calculator helps estimate those payments and the potential tax savings. You start by selecting a vehicle and providing your name, phone, and email, then the tool shows indicative costs. For a personalised quote, you need to enter your employer and salary.
The calculator uses your employer's tax classification and salary packaging arrangements, plus your income level, to estimate lease costs and tax benefits. Results are indicative only, but they give you a ballpark figure before you commit.
How does a novated lease affect your gross pay and salary index?
Your gross pay is the starting point. The Salary Index measures full-time adult ordinary-time earnings, with 100 equal to $108,352 a year (based on ABS Average Weekly Earnings, May 2026). If you earn $80,000, your index is about 74. When you salary package a car, your taxable income drops because lease payments come out before tax. That doesn't change your gross pay—your employer still reports your full salary to the ATO—but your assessable income for tax purposes is lower.
For example, if your gross salary is $100,000 (index 92.3) and you package $15,000 in lease costs, your taxable income becomes $85,000. You pay less tax, but your super guarantee may also be affected if your employer calculates it on the reduced salary. The super guarantee is 12% from 1 July 2026, so check your employment contract.
Tax savings and the EV discount
The main benefit of a novated lease is paying for the car with pre-tax dollars. The calculator shows estimated tax savings based on your marginal tax rate. For 2026–27, resident tax rates (excluding Medicare) are: nil up to $18,200, 15% from $18,201 to $45,000, 30% to $135,000, 37% to $190,000, and 45% above that. Plus a 2% Medicare levy. If you're in the 30% bracket, every dollar of lease cost saves you 30 cents in tax plus 2 cents Medicare.
Electric vehicles get an extra benefit: the government's EV Discount Policy removes Fringe Benefits Tax (FBT) on eligible EVs purchased through a novated lease, up to the Luxury Car Tax limit ($91,661 in FY 2026-27). That means you don't pay FBT on the private use of the car, increasing your savings. The calculator accounts for this if you select an eligible EV.
How does this relate to awards and minimum wages?
Your base pay might come from a modern award or the national minimum wage. The national minimum wage from 1 July 2026 is $26.44 per hour, $1,004.90 per week, annualised $52,255, index 48.2. Award minima rose 4.75% from 1 July 2026. If you're on an award, your classification determines your minimum rate. A novated lease is usually only available if your employer offers salary packaging, which is more common in higher-paying roles or certain industries.
For example, the pay guides for retail trade (index 75.9) or accommodation and food services (index 72.5) show lower average earnings, meaning less tax to save. In contrast, professional services (index 114.7) or mining (index 154.7) offer higher gross pay and potentially bigger tax benefits from a novated lease.
Super considerations
When you salary package a car, your employer may calculate super guarantee on your reduced salary (the post-packaging amount). The super guarantee rate is 12% from 1 July 2026, with a maximum contribution base of $270,830. If your employer uses the reduced salary, your super contributions could be lower. Some employers maintain super on your original salary—check your policy. The calculator doesn't model this, so factor it in separately.
State and industry variations
Your location and industry affect your gross pay and therefore the potential savings. For instance, the ACT has the highest average earnings (index 109.9, annualised $119,090), while Tasmania is lowest (index 88.6, $96,008). States with higher pay offer more tax bracket headroom. Similarly, industries like mining (index 154.7) or professional services (114.7) are more likely to have employees who benefit from novated leasing.
Using the calculator wisely
The smart salary novated lease calculator is a starting point. It gives you an estimate, but actual costs depend on your employer's salary packaging policy, the car's residual value, running costs, and your personal tax situation. The how the index works page explains how we measure earnings, but remember that salary packaging changes your taxable income, not your gross pay. Always seek professional advice before entering a novated lease agreement.
Final thoughts
A novated lease can reduce your tax bill, especially if you're in a higher tax bracket or choose an eligible EV. The smart salary novated lease calculator helps you see the numbers quickly. But your gross pay and salary index remain the foundation—they determine how much you can save. Use the calculator alongside your pay slip and award conditions to make an informed decision.
Questions people ask
What is the smart salary novated lease calculator?
It is an online tool from Smart that estimates the costs and potential tax savings of a novated lease. You enter your vehicle choice, employer details, and salary, and it shows indicative lease payments and how much tax you might save by salary packaging the car.
How does the calculator affect my gross pay and salary index?
The calculator itself doesn't change your gross pay, but it shows how salary packaging reduces your taxable income. Your gross pay before packaging determines your salary index (e.g., 100 for full-time adult ordinary-time earnings). The tax savings come from paying lease costs from pre-tax salary, lowering your assessable income.
Does the calculator include superannuation?
No, the novated lease calculator focuses on lease costs and tax savings. Superannuation is not directly included, but note that salary packaging a car reduces your gross salary for super guarantee purposes if your employer uses the reduced salary base. The super guarantee rate is 12% from 1 July 2026, so check your employer's policy.
