Safe budget & repayment stress tester
See your repayment today, and under realistic rate-rise scenarios — no green or red verdict, just the numbers and the trade-offs.
Optional resilience scenarios — leave at 0 to skip a scenario:
Methodology and assumptions
Formula: standard principal-and-interest amortisation (monthly repayment = loan × monthly rate × (1+monthly rate)^n ÷ ((1+monthly rate)^n − 1)).
Default rate: 6.2% — the RBA's published average owner-occupier variable housing lending rate (Reserve Bank of Australia, verified 29 Jul 2026), used only as a reference starting point; replace it with your own quoted or actual rate for an accurate result. The RBA cash rate itself is economic context, not a mortgage rate, and is not used as the default here.
Rate-rise scenarios: illustrative personal scenarios at +1, +2 and +3 percentage points alongside APRA's actual minimum serviceability buffer (Australian Prudential Regulation Authority, verified 29 Jul 2026) (+3.0 points), shown separately since the buffer regulates what banks must test for, not a personal recommendation, and individual lenders may apply their own credit policy on top of it.
Resilience scenarios: optional income reduction (job loss, reduced hours or parental leave), a one-off unexpected repair, a one-off owners corporation special levy, an ongoing insurance increase, and a combined scenario applying several at once.
Excluded: offset accounts, extra repayments, LMI capitalisation, and interest-only periods.
