One of the first questions most home buyers ask is, “How much can I borrow?” The answer depends on much more than your salary. Mortgage lenders look at your income, monthly commitments, credit history, deposit, and overall affordability before deciding how much they’re prepared to lend. While many people can borrow around 4 to 4.5 times their annual income, every lender has different criteria, and some may lend more or less depending on your circumstances. In this guide, we’ll explain what affects how much you could borrow, how lenders calculate affordability, and what you can do to improve your borrowing potential.
Most lenders will typically lend around 4 to 4.5 times your annual income, although some may lend more depending on your circumstances.
Your income, monthly commitments, credit history and deposit all influence how much you could borrow.
A larger deposit may improve your mortgage options by reducing your loan-to-value (LTV).
Every mortgage lender uses its own affordability assessment, so borrowing limits can vary significantly.
Speaking to a whole-of-market mortgage broker can help you find the lender most likely to maximise your borrowing potential.

How Do Mortgage Lenders Calculate How Much I Can Borrow?
Mortgage lenders don’t simply multiply your salary by a fixed number. Instead, they’ll carry out an affordability assessment to determine whether you can comfortably afford the mortgage both now and in the future. They’ll look at your income, regular household spending, existing credit commitments and how your finances would cope if interest rates increased. Every lender has its own affordability calculator, which is why the amount you can borrow can vary significantly from one lender to another.
Does My Income Affect How Much I Can Borrow?
Yes. Your income is one of the biggest factors lenders consider. Basic salary is usually included, but many lenders will also take overtime, bonuses, commission, shift allowances, maternity pay, pensions and certain benefits into account. If you’re self-employed, lenders will typically assess your income using your accounts or tax calculations rather than payslips. The more stable and sustainable your income appears, the more comfortable a lender may be lending to you.
What Other Factors Affect How Much I Can Borrow?
Income is only part of the picture. Mortgage lenders will also consider your monthly expenditure, credit commitments, childcare costs, financial dependants, outstanding loans, credit cards and any other ongoing commitments. They’ll also look at your age, the mortgage term, the type of property you’re buying and your credit history. Together, these factors help determine how much you could realistically afford to borrow.

Does My Deposit Affect How Much I Can Borrow?
Yes, although not always in the way people expect. Your deposit doesn’t directly increase the amount a lender is willing to lend, but it reduces the amount you need to borrow. A larger deposit can also lower your loan-to-value (LTV), giving you access to more competitive mortgage rates and a wider range of lenders. In some cases, this can improve affordability and increase your borrowing options.
Can I Borrow More Than 4.5 Times My Salary?
Sometimes. While many lenders use income multiples of around 4 to 4.5 times annual income, some lenders may offer higher income multiples for applicants with strong affordability, higher earnings or certain professions. Borrowing more isn’t always the best option, so it’s important to choose a mortgage that’s comfortable and sustainable over the long term.
How Does My Credit History Affect My Borrowing?
Your credit history plays an important role in a lender’s decision. A strong credit profile may give you access to more lenders and better mortgage products, while missed payments, defaults or County Court Judgments (CCJs) could reduce the amount you’re able to borrow or limit your lender choice. Checking your credit report before applying can help you identify and correct any issues.
Can I Increase How Much I Can Borrow?
There are several ways you may be able to improve your borrowing potential. Saving a larger deposit, paying off existing debts, improving your credit score, extending the mortgage term or applying jointly with another borrower could all increase the amount you’re able to borrow. Because every lender assesses affordability differently, speaking to a whole-of-market mortgage broker can also make a significant difference.
Should I Get a Mortgage in Principle First?
A Mortgage in Principle (also known as an Agreement in Principle) gives you a good indication of how much you may be able to borrow before you start viewing properties. It can also show estate agents and sellers that you’re a serious buyer. While it isn’t a formal mortgage offer, it’s often one of the first steps in the home-buying process.
