In Australia, being a borrower and eyeing getting a home mortgage comes with a lot of responsibility. As a borrower, you are responsible for ensuring that you have the capacity to repay your loan and that you can afford the repayments.

It is quite important to understand your borrowing capacity and affordability before taking out a loan. Borrowing capacity is the amount you're able to borrow without putting your financial stability at risk. Affordability is the amount you can afford to repay each month.

Aside from understanding borrowing capacity and affordability, it's also key to differentiate the two as well. Continue reading to learn more.

What Is Borrowing Capacity?

When you’re hoping to take out a loan, one of the first things a lender will assess is your borrowing capacity. Borrowing capacity is simply the amount of money you can borrow without putting yourself at financial risk, determined by a lender using a debt-to-income ratio (DTI).

Borrowing capacity can influence whether or not they can get the loan and how much they will have to pay back. One's income is quite an important factor in determining your borrowing capacity. The higher your income, the more money you’ll be able to borrow soon. 

What Is Borrowing Affordability?

When you're considering borrowing money, it's important to make sure that you can afford the payments. Borrowing affordability is a key concept in personal finance. Borrowing affordability is the amount of money that a borrower can afford to pay back a loan. This includes the monthly payments, as well as any other associated costs.

There are a number of online calculators that can help you calculate your borrowing affordability. These calculators will take into account your income, debts, and credit score to estimate how much money you can borrow. It's also possible to connect with a mortgage broker to discuss your affordability.

What’s the Difference between Capacity vs Affordability?

Capacity and affordability are both important concepts when considering borrowing money. Capacity is the maximum amount that you can borrow based on your income and debts. Affordability is the amount of money that you can afford to pay back on loan.

It's important to consider both capacity and affordability when taking out a loan. Borrowers don't want to take out more money than you can afford to pay back. On the other hand, you also don't want to miss out on opportunities by borrowing too little.

What Factors Affect Both Capacity and Affordability?

A couple of factors can affect both your borrowing capacity and affordability. Your income is the most important factor. Other factors, such as your debts and your credit score, can also affect your capacity and affordability. Here's an outline to detail these main factors.

  • Income. The more money a borrower makes, the more they can afford to borrow. Lenders will look at your income when considering a loan. They want to make sure that you have the ability to repay the loan.
  • Debts. If you have a lot of debt, it may be difficult to qualify for a loan. Lenders will look at and assess an applicant's debt-to-income ratio when considering a loan, and a higher debt-to-income ratio can make it tough to qualify for a loan.
  • Credit Score. A high credit score typically indicates that you're a responsible borrower. This can make it much easier to qualify for a loan. A low credit score can make it more difficult to qualify for a loan.


Remember that when taking out a home loan in Australia, your borrowing capacity and affordability is of the utmost importance. Lenders will assess every person's current financial situation, and it is important to be honest and upfront about your circumstances to ensure you are not putting yourself under undue financial stress.
