Your borrowing capacity is the maximum amount a lender will let you borrow based on your income, expenses, debts, and the deposit you have available.

Lenders use a handful of core numbers to arrive at that figure. Income is the starting point, but they also factor in your regular expenses, any existing debts, and a buffer to make sure you can still afford the repayments if interest rates climb. The result is a dollar figure that tells you what you can afford to borrow, not necessarily what you should borrow. Knowing the calculation before you apply for a home loan means you can see where you sit and what might need adjusting if the number comes back lower than expected.

Around Jindabyne, where property types range from weekender cabins to full-time residences and rural blocks, the way lenders assess your situation can shift depending on whether the property is owner occupied or an investment, and whether you earn consistent PAYG income or run your own business. The calculation itself is straightforward once you know what goes into it.

How lenders assess your income

Lenders start with your gross income, which is your pay before tax. If you are on a salary or regular wage, they take your annual figure and divide it by twelve to get a monthly amount. Overtime, bonuses, and allowances can sometimes be included, but only if you have been receiving them consistently for at least six months and they are likely to continue.

For anyone self-employed or running a tourism or trades business in the Snowy Mountains, lenders typically average your last two years of taxable income. That means the income you declare on your tax return is what counts, not your turnover or gross receipts. If your income varies between summer and winter seasons, the lender will take the average and may ask for an accountant's letter confirming your year-to-date position.

Consider a buyer who works full-time in hospitality in Jindabyne and picks up extra shifts during the snow season. Their base salary is $55,000, and they earn another $8,000 over winter. If the overtime has been happening for two years and is documented on payslips, most lenders will include it. That brings their assessed income to around $63,000, which directly affects how much they can borrow.

What counts as committed expenses

Once lenders have your income, they subtract your committed expenses. These include rent or mortgage repayments on any property you already own, personal loan repayments, car loans, credit card limits, buy now pay later accounts, child support, and school fees if applicable.

Credit card limits matter more than your actual balance. If you have a card with a $10,000 limit and you only owe $500, the lender still assumes you could spend the full $10,000 and calculates a minimum monthly repayment based on that. The same applies to any personal loans or car loans you are still paying off. The monthly commitment reduces your borrowing capacity even if the loan is nearly paid out.

In practice, closing unused credit cards or reducing limits before you apply can lift your capacity by several thousand dollars. A $15,000 credit card limit might cost you around $40,000 in borrowing power, depending on the lender's calculation.

Living expenses and the household expenditure measure

Lenders also factor in your living expenses, which cover groceries, utilities, transport, insurance, phone bills, and general household costs. Some lenders use the figure you declare on your application, but most apply a minimum benchmark called the Household Expenditure Measure, or HEM. This is a standardised estimate based on household size and location, published by the Melbourne Institute.

For a single person in regional New South Wales, HEM sits around $1,800 to $2,000 per month. For a family of four, it is closer to $3,500 to $4,000. If your declared expenses are lower than HEM, the lender will use HEM instead. If your actual costs are higher, they will use your declared figure.

This matters in areas like Jindabyne where heating costs are higher than the state average, especially if you are living in a property year-round rather than using it as a holiday rental. Lenders do not adjust HEM for local climate, so it pays to declare realistic figures if your costs genuinely exceed the benchmark.

The interest rate buffer and serviceability test

Lenders do not assess your repayments at the current interest rate. They add a buffer, usually between 2.5% and 3%, to make sure you can still afford the loan if rates go up. On top of that, they apply a minimum assessment rate, which is often around 3% higher than the actual rate you will pay.

If the current variable rate on an owner occupied loan is sitting around 6%, the lender might assess your application at 9%. That means they calculate your repayments as if you were paying 9%, even though you will only be paying 6% when the loan settles. It is a stress test, and it directly limits how much you can borrow.

The buffer is why two buyers with the same income and deposit can have different borrowing capacities depending on which lender they approach. Some lenders use a higher buffer or a higher minimum assessment rate, which shrinks the amount they are willing to lend.

How deposit size affects the loan amount

Your deposit does not change your borrowing capacity in a strict sense, but it does affect how much you can actually borrow in practice. Lenders calculate your loan to value ratio, or LVR, by dividing the loan amount by the property value. Most lenders will lend up to 95% LVR if you are an owner occupier and up to 90% for an investment property.

If you are borrowing above 80% LVR, you will need to pay Lenders Mortgage Insurance, or LMI. This is a one-off premium that protects the lender if you default, and it can add several thousand dollars to your upfront costs. The premium increases as your LVR goes up, so a 95% loan carries a much higher LMI cost than a 90% loan.

Around Jindabyne, where property can include anything from alpine apartments to larger residential homes near the lake, the deposit you need will vary based on the property value. A first home loan with a 5% deposit might be possible, but your borrowing capacity still has to cover the purchase price and any LMI that applies.

Owner occupied versus investment property

Lenders assess owner occupied home loans more favourably than investment loans. The interest rate is usually lower, and the serviceability calculation is slightly more generous because you are living in the property rather than relying on rental income.

If you are buying an investment property, lenders will include rental income in your assessment, but they only count 80% of it. The 20% reduction accounts for vacancy periods and ongoing costs like rates, insurance, and maintenance. If the property is a holiday rental in Jindabyne, some lenders will apply an even larger discount or exclude the income altogether unless you can show a strong rental history.

This distinction matters if you already own a property and you are looking to borrow again. The way lenders treat your existing property, whether it is owner occupied or rented out, will affect how much you can borrow for the next one.

When to check your capacity before applying

Checking your borrowing capacity early means you know what price range to focus on before you start looking at properties or attending auctions. It also gives you time to adjust your position if the number comes back lower than expected.

Common adjustments include paying down credit cards, closing unused accounts, increasing your deposit, or adding a second income if you are applying jointly. If you are self-employed, you might wait until after your next tax return if your income has increased, so the lender can assess you on the higher figure.

Getting a home loan pre-approval gives you a formal indication of what you can borrow, and it shows sellers that you are in a position to proceed. Pre-approval is not a guarantee, but it is based on the same calculation lenders use for final approval, so the figure is reliable as long as your circumstances do not change.

Frequently Asked Questions

What is borrowing capacity and how is it calculated?

Borrowing capacity is the maximum amount a lender will let you borrow based on your income, expenses, debts, and deposit. Lenders assess your gross income, subtract your committed expenses and living costs, then apply an interest rate buffer to make sure you can afford repayments if rates increase.

Why do credit card limits affect how much I can borrow?

Lenders assume you could spend up to your full credit card limit, not just your current balance. They calculate a minimum monthly repayment based on that limit, which reduces your borrowing capacity even if you rarely use the card.

How does being self-employed change the borrowing capacity calculation?

Lenders typically average your last two years of taxable income if you are self-employed. They use the income you declare on your tax return, not your turnover, and may ask for an accountant's letter to confirm your current financial position.

What is the interest rate buffer and why does it matter?

The interest rate buffer is an additional 2.5% to 3% that lenders add to the current interest rate when assessing your application. It ensures you can still afford repayments if rates rise, and it directly limits how much you can borrow.

Does my deposit size change my borrowing capacity?

Your deposit does not change your borrowing capacity directly, but it affects your loan to value ratio and whether you need to pay Lenders Mortgage Insurance. A larger deposit reduces your LVR and can lower your upfront costs.
