Three consecutive Reserve Bank rate hikes delivered through 2026 have cut deeply into how much Australians can actually borrow for a home, with new analysis showing a single-income buyer on average wages has lost roughly $36,000 in borrowing power since the start of the year, while a dual-income couple has lost around $72,000.
The figures highlight just how quickly rate movements ripple through to real-world purchasing power, even when the headline rate change sounds modest in isolation.
How the Numbers Add Up
On an average loan of $736,000, each 25 basis point rate increase adds roughly $120 a month to repayments. With three hikes delivered in succession through the year, many borrowers are now absorbing approximately $360 extra per month compared to where they started 2026 — money that comes directly out of either lifestyle spending or, for prospective buyers, the loan size a lender is willing to approve.
Why Borrowing Power Falls Faster Than Repayments Rise
Lenders apply serviceability buffers when assessing how much they’ll lend — typically testing whether a borrower could still afford repayments at a rate several percentage points above the current one. As actual rates rise, that buffer compounds, meaning borrowing capacity can fall by a larger dollar amount than the simple repayment increase alone would suggest.
How Buyer Behaviour Is Shifting
The reduced borrowing power is already reshaping what buyers are purchasing. More buyers are gravitating toward units and townhouses rather than detached houses, toward middle-ring suburbs rather than inner-city locations, and toward lower price-point suburbs where a reduced borrowing capacity still gets them genuine options.
Property analysts note this is a familiar pattern from previous rate cycles — when the RBA delivered 13 consecutive rate rises through 2022 and 2023, similar shifts in buyer behaviour and price-bracket competition occurred, even as overall prices continued rising through much of that period due to undersupply.
What This Means If You’re Buying Soon
Anyone planning a purchase in the near term should get updated finance pre-approval rather than relying on a borrowing capacity estimate from even a few months ago — the gap between what you could borrow in January and what you can borrow now may be larger than expected. Speaking with a mortgage broker about how the cumulative rate rises affect your specific situation is a sensible first step before house hunting in earnest.
