Quote savings vs your real financial position

Australian fleet quotes usually include a blue or highlighted card: "How much you'll save" — often $30,000–$40,000 over a 36-month lease. That figure is built from monthly lines you can see on the same page: GST relief on packaged costs, PAYG (income tax) relief on salary sacrifice, and sometimes a luxury-vehicle adjustment.

Mathematically, it answers: "How much tax do I avoid by running this car through payroll instead of paying equivalent costs from money that has already been taxed?" It does not answer: "Am I richer than if I had financed or bought the car another way?"

Take a typical 36-month Tesla Model Y quote on $190,000 salary (figures from a standard SG Fleet-style layout):

• Package total (pre-tax): $2,304.68 per month
• PAYG relief on that package: about $898.83 per month (37% tax + 2% Medicare at this salary)
• GST component in the savings card: about $223.13 per month
• Luxury levy adjustment: −$73.45 per month
• Net "monthly savings" shown: about $1,048.51 → × 36 months ≈ $37,746 headline

You still pay roughly $1,405 per month from take-home pay for the package (after PAYG relief). The quote is not saying the car is free — it is saying the tax system subsidises part of the cost.

A complete personal comparison must also count:

• Finance rate — novated leases often sit around 8–11% effective; personal loans may be lower
• Fees — establishment, PPSR, package management, optional insurances
• Residual balloon — typically 46.88% of capital on a 36-month lease, payable at the end if you want to keep the car
• Opportunity cost — cash or offset-account money could have reduced home-loan interest
• Side effects — reportable fringe benefits can affect HECS repayments, childcare subsidy tests, and Division 293 tax
• Flexibility — early exit, job change, or rollover into another lease changes the maths

Some calculators implicitly compare your novated package to funding the same inflated bundle entirely from after-tax dollars, with no GST recovery. That baseline makes almost any lease look attractive because it ignores realistic alternatives.

A stronger approach uses the same car, the same years, and the same driving assumptions, then contrasts:

• Cash purchase — drive-away price, running costs, and what you give up in offset or investment returns
• Car loan — principal, interest, running costs, and ownership at the end
• Status quo — keeping your current vehicle and avoiding upgrade costs altogether

When you model properly, group everything into three areas over the full lease life — not just the monthly payroll lines:

• Cash out — every payment you make: lease rentals, running costs, fees, and the residual if you buy the car
• Liabilities — how your funding choice affects other debts (e.g. less money in an offset account means more mortgage interest)
• Assets — the car's value when the lease ends if you sell or trade in

Novate is built to mirror provider quote cards and check PDFs line by line — package sub-total, luxury levy, PAYG, GST credit on purchase, and lease rental. That helps you catch errors or understand a salesperson's document before you sign.

It is not a full lifetime wealth model. Use it to audit the quote; use your own comparison (or professional advice) to decide whether the deal beats your realistic alternatives.
