Debt-to-income ratio

v1.1 — updated September 2025 (HECS excluded from DTI per APRA)
Total debt across all loans cannot exceed 6 times gross annual income. GetReal uses 6× as its DTI ceiling — the dominant cap at mainstream Australian lenders as directed by APRA macro-prudential policy.

APRA's macro-prudential framework directs lenders to limit high-DTI lending. While APRA does not set an absolute hard cap, mainstream lenders have adopted 6× gross income as their practical ceiling. GetReal applies 6× as the upper bound for Ceiling 2.

Max total debt = gross_annual_income × 6 Max new mortgage = max_total_debt − existing_mortgage_balances − credit_card_limits // full limit, not balance − car_loan_balances − personal_loan_balances // HECS/HELP excluded since 30 Sep 2025

What counts as debt

Debt typeHow it's counted
Existing mortgagesOutstanding balance
Credit cardsTotal approved limit — not the balance
Car / personal loansOutstanding balance
HECS/HELPExcluded since 30 September 2025
BNPL (Afterpay etc.)Outstanding balance if declared
Credit card limits are counted in full regardless of actual balance. A $20,000 limit with a $0 balance still adds $20,000 to total debt. Reducing or closing cards before applying can materially increase borrowing capacity.
Worked example — couple, $180,000 combined income
Gross income (couple): $180,000/year DTI cap (6×): $1,080,000 total debt Existing car loan: − $22,000 Credit card limit: − $15,000 ──────────────────────────────────────── Max new mortgage: $1,043,000
