How Much Can I Borrow for a Home Loan in Australia?

One of the first questions most buyers ask when considering property is:

How much can I borrow for a home loan?

Your borrowing power determines what price range you can realistically consider when searching for property. It also influences the size of your deposit, your loan repayments, and how lenders assess your financial position.

In Australia, lenders calculate borrowing capacity using a combination of income, debts, expenses, and financial stability.

This guide explains how borrowing power works, what affects it, and how you can increase it before applying for a home loan.

How Lenders Calculate Borrowing Power

When you apply for a home loan, lenders assess whether you can comfortably repay the loan over time.

They look at several key factors.

Your Income

Income is the starting point for borrowing calculations.

Lenders consider:

• salary or wages
• bonuses or overtime
• rental income
• investment income
• self-employment income

Stable income with consistent employment history generally improves borrowing capacity.

Existing Debts

Current debts reduce how much you can borrow.

These may include:

• credit cards
• personal loans
• car loans
• HECS or HELP debt
• buy now pay later accounts

Even unused credit card limits can reduce borrowing power because lenders assume you could use the full limit.

Living Expenses

Lenders review your regular expenses to estimate how much money remains available for loan repayments.

These expenses include:

• groceries
• utilities
• childcare
• insurance
• transport
• lifestyle spending

Banks also use benchmark living expense standards when assessing applications.

Loan Interest Rate Buffers

Australian lenders apply a serviceability buffer of 3% when calculating borrowing capacity.

This means your loan must remain affordable even if interest rates rise.

For example, if the current mortgage rate is 6%, the lender may assess the loan at around 9% to ensure repayments remain manageable in the future.

Dependants

Households with children or dependents generally have lower borrowing capacity because living expenses are higher.

Borrowing Capacity Examples

Every borrower is different, but the table below shows rough borrowing estimates based on income.

IncomeApproximate Borrowing Capacity

$80,000 $350,000 – $420,000

$120,000 $500,000 – $650,000

$160,000 $700,000 – $850,000

$200,000 $900,000 – $1,100,000+

These estimates depend on debts, expenses, and lender policy.

Different lenders can produce very different borrowing results, which is why comparing lenders can make a significant difference.

How Your Deposit Affects Borrowing Power

Your deposit plays an important role in how much you can borrow and what loan options are available.

5% Deposit

Some lenders allow buyers to purchase property with a 5% deposit, particularly first home buyers using government support schemes.

However, borrowing with a smaller deposit usually requires Lenders Mortgage Insurance (LMI).

10% Deposit

A 10% deposit provides more lender options and may reduce LMI costs.

Many buyers aim for this level when entering the property market.

20% Deposit

A 20% deposit is often considered ideal because it usually avoids Lenders Mortgage Insurance and can provide access to more competitive interest rates.

What Can Reduce Your Borrowing Power

Many buyers are surprised by how much certain financial factors affect borrowing capacity.

Common examples include:

Credit Cards

Even unused credit card limits reduce borrowing power.

For example, a $10,000 credit card limit can significantly lower how much a lender is willing to approve.

Personal Loans and Car Loans

Monthly repayments from personal loans or car finance reduce the income available for mortgage repayments.

Buy Now Pay Later Accounts

Some lenders treat these facilities similarly to other debts.

Closing unused accounts can sometimes improve borrowing capacity.

High Living Expenses

Large discretionary spending can reduce how much lenders believe you can afford to repay.

How to Increase Your Borrowing Power

Before applying for a home loan, there are several steps that may improve your borrowing capacity.

Reduce Existing Debts

Paying down personal loans or credit card balances can increase borrowing power.

Lower Credit Card Limits

Reducing unused credit limits may improve how lenders assess your application.

Consolidate Debts

Combining multiple debts into a single loan can sometimes improve serviceability.

Choose the Right Lender

Different lenders use different serviceability models.

Some lenders may allow significantly higher borrowing capacity depending on your financial position.

This is one reason many buyers choose to work with a mortgage broker.

Borrowing Power for First Home Buyers

First home buyers often have access to government programs that may assist with purchasing property.

These may include:

• First Home Owner Grant
• First Home Guarantee Scheme
• stamp duty concessions (depending on the state)

These programs can reduce upfront costs and allow buyers to enter the property market with a smaller deposit.

Frequently Asked Questions

How much income do you need to buy a house in Australia?

The required income depends on property price, deposit size, and debt levels. As a rough guide, a household earning around $120,000 may borrow between $500,000 and $650,000, depending on lender policy.

Does HECS or HELP debt affect borrowing capacity?

Yes. Lenders include HECS or HELP repayments when calculating borrowing capacity because they reduce disposable income.

Some lenders ignore them if the balance is low or the debt will he paid off within the year.

Does pre-approval tell you exactly how much you can borrow?

Pre-approval provides a strong indication of borrowing capacity, but the final loan amount depends on the property and lender valuation.

Can different lenders offer different borrowing amounts?

Yes. Borrowing capacity can vary significantly between lenders because they use different serviceability models.
