The RBA raised the cash rate to 4.85%. Budgeting apps and AI can help model the impact, but they cannot negotiate your loan for you.
Another rate rise for Australian borrowers
On 3 November 2026, the Reserve Bank of Australia announced a 0.25-percentage-point increase in the cash rate target to 4.85%, effective 4 November. It was the fifth increase of the year. The cash rate is not the same as an individual mortgage rate, and lenders decide whether and when to pass changes through.
What the numbers mean
As a simple interest-only illustration, a 0.25-percentage-point increase adds approximately A$208 per year for each A$100,000 of outstanding principal, or A$20.83 per month. On A$800,000, that is around A$167 in additional monthly interest initially if the full increase is passed on. Actual principal-and-interest repayments depend on remaining term, rate and loan structure.
Where digital tools can help
A reliable mortgage calculator can estimate repayments under different rates. Budgeting apps can show recurring expenses and identify room to adjust spending. AI assistants can help create comparison checklists and explain terminology, but may make arithmetic errors or use outdated lender offers. Verify figures with lender calculators and statements.
What technology cannot do
No app can guarantee refinancing approval or a lower rate. Be cautious about services asking for banking credentials or promising automatic savings. When comparing loans, include fees, offset features, comparison rates and the cost of switching. Consider a licensed professional for personalised credit advice.
TheTechBoom take
The best use of AI during a rate-rise cycle is to make financial decisions easier to understand, not to outsource the decision itself.
