A debt-to-income ratio (DTI) or loan to income ratio (LTI) is a way for banks to measure your ability to make mortgage repayments comfortably without putting you in financial hardship.

While it’s an adequate stress test for approving home buyers, it doesn’t always make sense for property investors, who can simply sell their investment property if they need to.

Which lenders apply a DTI ratio limit?

  • Non-bank lenders: Non-Australian Deposi-taking Institutions (ADIs) do not apply DTI limits because they are unregulated by the Australian Prudential Regulation Authority (APRA).
  • ANZ: Applications where the DTI ratio is greater than 9 will no longer be considered home loans by ANZ.
  • Commonwealth Bank: They monitor applications with a DTI higher than 4.5, while applications that are 7 DTI or higher need to be manually approved by their credit department.
  • National Australia Bank: Their DTI ratio cap is 9 for all home loan applications and their Loan to Income ratio (LTI) cap is 7.
  • Westpac: For DTI ratio of 7 or greater, your application will be referred to their credit department for further review.
  • Other lenders: Other major banks and lenders are set to release their own DTI ratio benchmarks.

What is a debt-to-income ratio?

Your debt-to-income ratio is your total debts and liabilities divided by your gross income (before tax income).

Essentially, your DTI ratio takes into consideration your full debt exposure ensuring you can meet your home loan repayments today and in the future.

For example, let’s say you’re a couple each earning a yearly gross income of $80,000 each ($160,000 in total), you want to borrow $500,000, and your total liabilities are:

  • $500,000 for the new mortgage
  • A credit card with a monthly limit of $2,000
  • Total debt: $502,000

The following formula would then be applied: $502,000 ÷ $160,000 = 3.14 DTI

What this means is that your total debt is 3.14 times your combined income.

Is this considered to be a high DTI?

In the above case, this would generally be acceptable to most lenders.

Generally speaking, a DTI higher than six times a borrower’s’ income (6 DTI) is considered to be a high risk that you will be put under financial stress if:

  • Your financial situation was to change suddenly.
  • Interest rates were to rise dramatically.
