Compare Big Four home loan interest rates: How do CBA, NAB, ANZ and Westpac stack up?

Key points

  • The Big Four banks (ANZ, CommBank, NAB and Westpac) are the lenders behind most home loans in Australia.
  • Smaller lenders often have lower home loan interest rates compared to the Big Four banks.
  • ANZ, CommBank, NAB and Westpac all cut variable rates on select home loans following the RBA’s May meeting.

When people apply for a home loan in Australia, they often go with one of the Big Four banks: ANZ, Commonwealth Bank, NAB or Westpac. But while these are household names, they don’t typically offer cheap home loans.

Since the Reserve Bank of Australia (RBA) began to cut the cash rate in 2025, the major banks are also scaling back their home loan rates. We monitor their movements so you can easily find the lowest Big Four interest rates on this page.

Whether you’re currently with ANZ, CommBank, NAB or Westpac, or you’ve got them on your home loan shortlist, it’s worth seeing how they stack up against each other as well as  smaller competitor banks.
