1. What is the APRA 3.0% Serviceability Buffer?
The Australian Prudential Regulation Authority (APRA) mandates that all Australian banks and regulated lenders assess prospective borrowers at an interest rate 3.0% above the current loan product rate. This regulatory test ensures borrowers can continue servicing their home loan if interest rates rise.
For example, if you apply for a variable home loan at 5.80%, the lender does not test your ability to make repayments at 5.80%. Instead, they assess your monthly income and expenses at a floor rate of 8.80%.
2. How the Buffer Impacts Your Maximum Borrowing Power
The 3.0% buffer significantly reduces borrowing capacity compared to simple repayment calculators. For an Australian household with a combined income of $150,000:
- At Actual Interest Rate (5.80%): Indicative loan capacity could reach $880,000.
- Under 3.0% APRA Assessment Rate (8.80%): Assessed borrowing power is restricted to approximately $680,000 to $710,000.
3. Household Expenditure Measure (HEM) vs Real Living Expenses
When assessing living expenses, lenders compare your declared 90-day bank transaction statements against statutory Household Expenditure Measure (HEM) benchmarks. Lenders will always use whichever figure is higher.
To maximize your borrowing power before applying, brokers recommend:
- Closing Unused Credit Cards: Every $10,000 credit limit reduces your borrowing power by approximately $45,000 to $50,000, even if the balance is $0.
- Consolidating Buy-Now-Pay-Later (BNPL): Afterpay and Zip accounts are treated as ongoing credit commitments.
- Reviewing Discretionary Subscriptions: Minimizing unnecessary recurring expenses 3 months prior to application.
4. Cross-Lender Assessment Variances: Why Broker Comparison Matters
While all major banks adhere to APRA guidelines, non-bank lenders and specialized institutions apply different calculation policies for secondary income streams:
- Overtime & Shift Allowances: Some banks shade overtime to 80%, while others accept 100% with a 2-year history.
- Bonus & Commission Income: Policies vary from 50% to 100% inclusion based on tenure.
- Casual & Contractor Employment: Lenders require between 3 months and 12 months in current roles.
