How a Novated Lease Can Affect Your Home Loan Borrowing Power
Buying a new car while planning to purchase a home can be an exciting milestone, but have you considered how your car financing could affect your ability to secure a home loan? For many Australians, a novated lease offers an attractive way to finance a vehicle while potentially benefiting from tax savings. However, before signing a lease agreement, it is important to understand how this financial commitment may influence your home loan borrowing capacity.
At AA Finance Solutions, we believe that making informed financial decisions is essential to achieving your property goals. Understanding the relationship between vehicle financing, income and mortgage assessments can help you plan ahead, avoid unexpected surprises and put yourself in a stronger position when applying for a home loan.
What Is a Novated Lease, and Why Does It Matter?
A novated lease is a vehicle financing arrangement in which an employee leases a car through an agreement involving their employer. Lease payments are generally deducted from the employee’s salary, often using a combination of pre-tax and post-tax income, depending on the arrangement and vehicle eligibility.
While a novated lease may provide tax advantages in certain circumstances, particularly for eligible electric vehicles, it can also reduce the income a lender considers when assessing your home loan application. Mortgage lenders look beyond your salary alone. They assess your disposable income, regular financial commitments, household expenses and ability to meet mortgage repayments.
This means that even if a novated lease feels manageable within your monthly budget, it could still affect how much a bank is willing to lend you. The key is to understand the potential impact before committing to the vehicle.
How Much Could a Novated Lease Reduce Your Borrowing Capacity?
The impact can be more significant than many borrowers expect. In modelling conducted by AA Finance Solutions’ Leonard Nagawidjaja, an applicant earning $130,000 per year was assessed using Bankwest and Macquarie servicing calculators. The scenarios compared borrowing capacity with no vehicle finance, a traditional car loan and an electric vehicle (EV) novated lease.
The results showed that the type of vehicle finance, lease duration and lender’s assessment method can all make a difference. In some scenarios, a traditional car loan reduced borrowing capacity more than a five-year EV novated lease. However, a shorter lease with higher fortnightly deductions could have a greater impact.

These figures highlight an important point: the impact of vehicle finance on your mortgage application is not determined by the car price alone. Your repayment commitments, income, lease structure and lender’s policies can all influence the outcome.
Why Does the Lease Term Matter?
One of the most important findings is the relationship between lease duration and borrowing capacity. A shorter novated lease generally means higher regular payments because the cost is spread over a shorter period. Those higher deductions can leave less income available for a lender to consider when calculating your home loan borrowing capacity.
For example, the modelling found that a two-year EV novated lease could reduce borrowing capacity by approximately 2.3 to 2.6 times the vehicle’s purchase price, depending on the lender and interest rate. By comparison, a five-year EV novated lease produced a smaller estimated impact of around 1.7 to 2.0 times the vehicle’s price in the scenarios examined.
A longer lease may therefore improve the borrowing capacity outcome, although it can also mean a longer financial commitment and different risks at the end of the agreement. The right choice depends on your property plans, cash flow and overall financial position.
How Do Banks Assess a Novated Lease?
Not all vehicle financing arrangements are assessed in the same way. A traditional car loan is typically treated as an ongoing financial commitment, with repayments reducing the income available for mortgage servicing.
A novated lease can be assessed differently. In the Bankwest and Macquarie scenarios examined in the article, lenders assessed the borrower using their reduced salary after relevant pre-tax lease deductions. Any applicable post-tax lease contribution may also be included as a financial commitment.
This distinction matters because lenders assess the income available to meet mortgage repayments, rather than simply looking at your gross annual salary.
However, lenders have their own credit policies, and assessment methods can change. The treatment of your particular lease may depend on its structure, the lender you apply to and your personal circumstances. This is why speaking with a mortgage broker before signing a vehicle finance agreement can be valuable.
Does a Higher Income Make a Difference?
Yes. The modelling also demonstrated that income can influence the scale of the impact.
For a borrower earning $300,000 per year, the estimated reduction in borrowing capacity associated with a five-year EV novated lease was approximately $80,000–$82,400 in the scenarios examined. This was a smaller multiple of the vehicle’s purchase price than in the $130,000 income scenarios.
The reason is that the lease deductions represent a smaller proportion of the higher-income borrower’s earnings. Nevertheless, a higher salary does not eliminate the impact of vehicle finance, and other factors such as household expenses, dependants, existing debts and the lender’s assessment criteria remain important.
The takeaway is simple: two people leasing the same car may experience very different outcomes when applying for a home loan.
Five Practical Steps Before Signing a Novated Lease
If buying a home is part of your future plans, a little preparation can help you make a more informed decision.
1. Establish your home-buying timeline
If you intend to buy a property in the next 6–24 months, review your borrowing capacity before committing to a new vehicle. Even if you are only beginning to save for a deposit, understanding your position early can help you plan.
2. Compare your borrowing capacity with and without the lease
Ask a mortgage broker to model both scenarios using your actual income, expenses and proposed lease details. This gives you a clearer picture of the potential trade-off before you make a commitment.
3. Obtain a detailed novated lease quote
Review the proposed deductions, lease term, interest rate, running costs and end-of-lease obligations. Avoid making a decision based solely on the advertised tax savings or fortnightly payment.
4. Compare all your vehicle financing options
Consider a novated lease, a traditional car loan and paying cash if appropriate. Each option has different implications for your income, ongoing commitments and available savings for a property deposit.
5. Make your decisions in the right order
If a home purchase is your priority, consider confirming your borrowing capacity and discussing your plans with a mortgage broker before finalising your car finance. This helps you understand the implications while you still have flexibility.
Conclusion: Plan Your Car Finance Around Your Property Goals
A new car and a new home are both major financial milestones. You should not necessarily have to give up one to achieve the other, but it is important to understand how the decisions work together.
The modelling discussed in this article shows that a novated lease does not automatically reduce borrowing capacity more than a traditional car loan. In some of the scenarios examined, a five-year EV novated lease produced a more favourable borrowing capacity outcome than a comparable car loan. Yet shorter lease terms, higher deductions and individual lender policies can change the result significantly.
At AA Finance Solutions, we believe that the best financial decisions start with the right information. Our goal is to help you understand your borrowing position, explore suitable lending options and make informed decisions that support your long-term property ambitions.
Before you sign your next car finance agreement, take the time to understand how it could affect your home loan. A conversation today could help you avoid unexpected borrowing limitations tomorrow.
