Understanding the Impact on Your Budget

A rate change might seem small in percentage terms, but the dollar impact on your monthly budget can be significant, especially for larger loans. The table above shows indicative changes based on standard principal and interest loans.

Key things to note:

  • Actual changes depend on your lender's margin and whether they pass on the full rate change
  • Interest-only loans will see smaller monthly changes but pay more interest overall
  • Fixed rate portions of split loans won't change until the fixed term expires

Frequently asked questions


For variable rate loans, most lenders adjust rates within 1-2 weeks of an RBA announcement. Your next scheduled repayment after the rate change takes effect will reflect the new amount.
