You’ve been saving for years, you’ve got a deposit ready, and you’ve mentally moved into a three-bedroom place with a lemon tree and room for a dog. Then you sit down with a lender, and they say you can borrow $120,000 less than you expected. Suddenly, half the listings you’ve been bookmarking are off the table. If you’ve ever Googled **how much can I borrow for a home loan Australia**, you’re in exactly the right headspace — but the answer isn’t one number. Borrowing power in 2026 is shaped by a complex mix of your income, expenses, debts, and the strict serviceability rules the Australian Prudential Regulation Authority (APRA) imposes on lenders. According to ABS data, the average new home loan size for owner-occupiers hit $624,000 in late 2025, yet two people earning the same salary can walk away with wildly different pre-approval amounts based on a few small, fixable factors.
In this guide, I’ll walk you through exactly how lenders calculate your borrowing capacity, the specific APRA buffer that’s pinching loans in 2026, a real-world table of how much different household types can typically borrow, and the practical steps you can take today to add tens of thousands to your maximum loan. You’ll also get a link to NeonPlay’s free Borrowing Power Calculator so you can run your own numbers in under two minutes. Let’s turn that vague question into a solid, informed number.
What Determines How Much You Can Borrow for a Home Loan?
Borrowing power isn’t a fixed multiple of your income — it’s the result of a detailed, ATO-informed assessment of your net disposable income after all expenses and debts. Lenders aren’t allowed to rely on a simple income multiplier anymore; responsible lending laws mean they must verify your living costs and stress-test your ability to repay if rates rise significantly. That assessment rests on three main pillars: your income, your expenses, and your existing financial commitments.
Income and Employment Type
Lenders look at your gross annual income from all sources: base salary, overtime (usually shaded to 80% or less), bonuses, commissions, rental income, and any Centrelink payments like Family Tax Benefit. Full-time permanent employees get the highest borrowing capacity because their income is stable. If you’re self-employed, a casual worker, or on a contract, lenders will typically average your last two years of tax returns and may discount variable income streams further. A sole trader showing $100,000 on their last notice of assessment might be assessed on only $85,000–$90,000 depending on the lender’s policy.
Expenses, Dependants, and the Household Expenditure Measure (HEM)
This is where many borrowers get a shock. Lenders don’t just take your word for what you spend — they cross-reference your declared living expenses with the Household Expenditure Measure (HEM), a benchmark that estimates annual living costs based on your income, location, and household size. In 2026, if you claim you spend $25,000 a year but the HEM says someone in your postcode with one child typically spends $38,000, the lender will use the higher figure. Dependants increase the HEM significantly — each child adds roughly $6,000–$8,000 to the annual living cost estimate. Two kids, and your borrowing capacity can drop by over $100,000.
Existing Debts and Credit Card Limits
Here’s a quiet borrowing-power killer: even if you pay off your credit card every month, the lender assumes you could max it out. The serviceability calculation adds a monthly repayment equal to 3%–3.8% of the card limit, not the balance. A $15,000 credit card limit with a zero balance still shaves about $45,000–$60,000 off your maximum loan because the system treats it as a $450–$570 monthly commitment. Other debts — car loans, personal loans, HELP debt — all reduce your net surplus and lower borrowing power. Lenders also check your credit report for any buy-now-pay-later facilities, which they now treat as unsecured debt.
How Lenders Calculate Your Borrowing Capacity in 2026
Once income, expenses, and commitments are tallied, the lender calculates your net monthly surplus — the amount left over after living costs, tax, and debt repayments. They then stress-test that surplus against a mortgage repayment at an interest rate much higher than what you’ll actually pay, to see if you can still afford the loan when rates rise.
The APRA Serviceability Buffer and Assessment Rate
As of early 2026, APRA requires lenders to assess your ability to repay at the higher of:
-
The product interest rate plus a 3% buffer, or
-
A floor rate (currently 6.50% for most lenders, though APRA may adjust it).
In practice, with competitive variable home loan rates around 5.80%–6.00%, the buffer pushes the assessment rate to around 8.80%–9.00%. That means the lender calculates your potential repayment as if your interest rate were 8.80%, not 5.80%. On a $500,000 loan over 30 years, the monthly repayment at 8.80% is roughly $3,950, compared to $2,930 at 5.80%. That extra $1,020 a month in hypothetical repayments dramatically limits how much they’ll lend you. This buffer has been the single biggest factor constraining borrowing power since APRA increased it from 2.5% to 3% in 2021. There is ongoing speculation APRA might lower it if rates fall further, but no change has been confirmed as of mid-2026.
A Quick Example of a Serviceability Calculation
Let’s take a couple, Alex and Sam, earning $160,000 combined with no kids, no debts, and estimated living expenses of $32,000 per year. After tax and expenses, their monthly surplus is about $6,500. The lender tests whether they can afford a loan repayment at an assessment rate of 8.80% on top of their living costs. Based on that stress test, their maximum borrowing capacity is around $720,000 — even though they could comfortably service a $900,000 loan at the actual rate of 5.80%. The buffer is the wall.

How Much Can Different Households Borrow? A Real-World Table
The table below illustrates typical borrowing capacity for different household profiles in 2026, assuming a 20% deposit, no existing debts beyond HELP, and a loan term of 30 years. These are estimates — every lender’s algorithm differs slightly, and your actual figure depends on precise expenses and credit history.
| Household Profile | Gross Annual Income | Dependants | Existing Debt (excl. HELP) | Estimated Max Borrowing | Max Purchase Price (with 20% deposit) |
|---|---|---|---|---|---|
| Single, no kids | $95,000 | 0 | $0 | $460,000–$510,000 | $575,000–$637,500 |
| Single, no kids | $130,000 | 0 | $0 | $630,000–$690,000 | $787,500–$862,500 |
| Couple, no kids | $160,000 | 0 | $0 | $710,000–$780,000 | $887,500–$975,000 |
| Couple, 2 kids | $160,000 | 2 | $0 | $580,000–$640,000 | $725,000–$800,000 |
| Couple, 2 kids | $160,000 | 2 | $20,000 car loan | $530,000–$590,000 | $662,500–$737,500 |
| Single parent, 1 child | $90,000 | 1 | $5,000 credit card limit | $370,000–$410,000 | $462,500–$512,500 |
*Assumptions: 8.80% assessment rate, 30-year term, HEM-based expenses, no negative credit events. Estimates only.*
The drop between a childless couple and the same couple with two kids is stark — roughly $130,000. And a modest car loan can shave off another $50,000. These numbers explain why it’s so valuable to clear debts and reduce credit card limits before applying.

How to Increase Your Borrowing Power Before You Apply
If the table above left you feeling a bit deflated, don’t panic. Borrowing power isn’t fixed — it’s a number you can actively improve over a few months with a handful of deliberate actions.
-
Reduce credit card limits. If you have a $20,000 limit and you only use $2,000, call the bank and ask to lower it to $5,000. That single change can increase your maximum loan by $45,000–$60,000, because lenders calculate repayment capacity based on the limit, not the balance. Close any unused cards entirely.
-
Pay off or reduce personal loans, car loans, and buy-now-pay-later balances. Every dollar of monthly debt repayment reduces your surplus by that amount. Clearing a $400-per-month car loan could lift borrowing power by roughly $50,000.
-
Tidy up your transaction account history. Lenders look at three to six months of bank statements. Regular gambling transactions, unexplained large transfers, or payday loan activity can spook a credit assessor. Keep your spending clean and consistent for at least three months before applying.
-
Demonstrate stable employment or income growth. If you’ve recently changed jobs, some lenders want you to have passed probation (usually six months). A promotion or pay rise that’s reflected in two payslips can immediately boost your assessed income.
-
Add a family member as a guarantor. This is a larger commitment, but a family guarantee allows a relative to use their own property equity as security for part of your loan, effectively removing LMI and increasing your borrowing ceiling. However, it puts their asset at risk, so it’s not a light decision.

Using a Borrowing Power Calculator: A Step-by-Step Process
Online calculators are your best friend when you’re exploring what’s possible, but they only deliver accurate results if you feed them accurate inputs. Here’s how to use one properly:
-
Gather your numbers. You’ll need your gross annual income (including salary, bonuses, any rental income), your partner’s income if buying jointly, a realistic figure for monthly living expenses, and a list of all debts including their monthly payments and credit limits.
-
Be honest about your expenses. The calculator will apply a HEM-like minimum, so if you understate your spending, the lender will still override it. A true figure gives you a more reliable outcome.
-
Enter your deposit size and property state. Stamp duty, LMI, and the loan-to-value ratio (LVR) all affect the loan amount you can borrow for a given purchase price. A 20% deposit avoids LMI, but a 10% deposit means LMI will be capitalised into the loan, slightly reducing your net borrowing power.
-
Review the assumptions. A good calculator will show you the interest rate buffer it’s using. NeonPlay’s free Borrowing Power Calculator automatically applies the current APRA serviceability buffer and the latest lender HEM benchmarks, so the estimate you get mirrors what a bank would assess.
Once you’ve run the calculator, you’ll have a clear figure for your maximum loan. From there, our compare home loans Australia without a broker guide can help you find the right loan with the features you need — and you’ll already know exactly how much you can spend.
5 Practical Tips for Australians Wanting to Max Their Borrowing Power
-
Cancel unused credit cards before you even speak to a lender. A $10,000 limit you never touch still costs you $30,000–$40,000 in borrowing power. It’s the lowest-effort, highest-impact move you can make — call your bank today and ask for a limit reduction.
-
Run your own credit file check before the lender does. Use a free service like Equifax or Experian to get your credit score and report. Look for any errors, old defaults, or duplicate enquiries. Disputing and fixing errors can take a few weeks, so do it early.
-
If you’re self-employed, have your last two years of tax returns and ATO notices of assessment ready. Lenders will average your income, and any unexplained drops in revenue will raise questions. Consider bringing forward any planned deductions to keep the assessed income looking consistent.
-
Time your application after a pay rise or bonus cycle. Even a $5,000 salary increase can add $20,000–$25,000 to your borrowing capacity. If you’re due for a promotion, wait until you have at least two payslips at the new rate before lodging an application.
-
Use an offset calculator to model the long-term savings of a smaller loan. Borrowing the absolute maximum the bank will give you isn’t always the best move. NeonPlay’s Mortgage Offset Calculator shows how even $20,000 in savings kept in an offset can reduce your interest and loan term. Sometimes a slightly cheaper property with a larger buffer gives you more peace of mind than a maximum loan ever will.
Common Mistakes Australians Make When Estimating Borrowing Power
Mistake 1: Assuming they can borrow 6–7 times their income like a few years ago.
In the low-rate environment of 2020–21, borrowing multiples of 6x or 7x were achievable. With the 3% serviceability buffer and higher rates, the realistic multiple in 2026 is closer to 4.5x–5.5x for singles and 4.5x–5x for couples with kids. Walking into a bank expecting a 7x multiple only leads to disappointment.
Mistake 2: Forgetting that HECS-HELP debt reduces disposable income.
HELP repayments are calculated as a percentage of your gross income (from 1% to 10%, depending on your income tier) and are treated as a compulsory outgoing by lenders. A couple earning $160,000 with large HELP debts could lose $8,000–$10,000 in annual net income in the eyes of the bank, lowering borrowing power by up to $60,000.
Mistake 3: Not disclosing all expenses and then getting a shock at the pre-approval stage.
Some borrowers try to game the system by understating their living costs, only for the lender to use the higher HEM figure anyway. Even if the lender initially accepts your stated expenses, they’ll verify them against your bank statements. Inconsistencies can delay or derail an approval.
Mistake 4: Applying for pre-approval with multiple lenders simultaneously without understanding credit score impacts.
Each full application triggers a hard credit enquiry. Multiple enquiries in a short window can temporarily lower your credit score and signal “credit shopping” to some algorithms. It’s fine to compare rates with soft quotes, but only apply for formal pre-approval with your top one or two lenders.

FAQ
How much can I borrow for a home loan in Australia based on my salary?
It depends on your exact income, expenses, and debts. As a rough guide, a single person earning $100,000 with no debts might borrow between $480,000 and $530,000 in 2026. A couple earning $160,000 together could potentially borrow $710,000 to $780,000 before factoring in dependants or major debts.
What is the APRA serviceability buffer in 2026?
APRA currently requires lenders to assess your repayment ability at the product interest rate plus a 3% buffer, or a floor rate around 6.50%, whichever is higher. This means you’re tested on a rate of roughly 8.80%–9.00% even though the actual rate you pay is closer to 5.80%–6.00%.
Does my credit card affect how much I can borrow?
Yes, significantly. Lenders assume you could max out the card and calculate a monthly repayment (3%–3.8% of the limit) as an ongoing expense. Even a card with a zero balance can reduce your maximum loan by $40,000–$60,000 depending on the limit.
Can I increase my borrowing power without earning more money?
Absolutely. Reduce credit card limits, pay off car loans and personal debts, close unused buy-now-pay-later accounts, and minimise discretionary spending on bank statements for three months before applying. These changes can add $50,000–$100,000 to your borrowing capacity.
How accurate are online borrowing power calculators?
Good calculators that use current APRA buffers and HEM benchmarks are very accurate as an estimate. They can’t capture every lender nuance, but a well-built tool like NeonPlay’s free calculator will give you a figure within $10,000–$20,000 of what a real lender would assess — enough to set your property search parameters accurately.
