Australia's Serviceability Assessment vs. US 28% Rule
APRA Serviceability Buffer (+3%)
Unlike the US DTI-based rules, Australian lenders assess your ability to repay at your actual rate + 3% (or a minimum floor, whichever is higher). At 6.2% actual rate, you must demonstrate affordability at 9.24%. This buffer protects against future rate rises and tightens qualification significantly.
No Rigid DTI Limit — But DTI Caps Apply
Australia does not mandate a single front-end DTI ratio, but most lenders apply internal limits — commonly 6× annual income as a maximum total borrowing. APRA also monitors the proportion of high-DTI lending (above 6×) and can impose macroprudential limits. Lenders also conduct a Household Expenditure Measure (HEM) assessment of your living costs.
Practical guide: Australian lenders typically allow total monthly repayments (all debts) of 30–35% of gross income, subject to the serviceability buffer. On A$125,000, your comfortable repayment ceiling is roughly A$3,125/month before other debts.
