Estimated borrowing capacity for a $90K gross annual salary based on Australian lender assessment criteria. Includes scenarios for single applicants, couples, borrowers with dependants, and those with HECS-HELP debt.
Lenders assess your capacity at a stressed rate (currently around 9% — your actual rate plus a 3% APRA buffer). The table below shows estimated maximum borrowing across common household scenarios.
| Scenario | Max Borrowing | Monthly Repayment (6.5%) | Property Budget (20% deposit) |
|---|---|---|---|
| Single, no kids, no HECS | $546,840 | $3,456/mo | $683,550 |
| Single, no kids, with HECS | $509,556 | $3,221/mo | $636,945 |
| Couple (equal income), no kids | $1.3M | $8,170/mo | $1.6M |
| Couple, 2 kids | $969,399 | $6,127/mo | $1.2M |
| Single, 1 kid | $497,127 | $3,142/mo | $621,409 |
Single on $90K: Maximum borrowing of approximately $546,840. With a 20% deposit, this supports a property budget of around $683,550.
APRA requires lenders to assess your ability to repay at a rate at least 3 percentage points above the loan product rate. With current variable rates around 6.0–6.5%, the assessment rate sits at approximately 9.0–9.5%. This buffer exists to protect you (and the lender) from future rate increases. It is the single biggest factor limiting borrowing capacity in 2026.
| Deposit | LVR | Max Property (Single) | Max Property (Couple) |
|---|---|---|---|
| 20% | 80% | $683,550 | $1.6M |
| 10% | 90% | $607,600 | $1.4M |
| 5% | 95% | $575,621 | $1.4M |
Note: A 5% deposit requires LMI (unless covered by the First Home Guarantee) and may not be offered by all lenders. The 20% deposit figures assume no LMI and represent the most straightforward lending scenario.
HECS-HELP (now called HELP) debt reduces your borrowing capacity because lenders include the compulsory repayment in their assessment. At a $90K salary, the compulsory HECS repayment rate is approximately 4% of your income, which is $3,600 per year or $300/month. This reduces maximum borrowing by approximately $37,285 compared to a borrower without HECS.
If you can afford to pay off your HECS debt before applying for a mortgage, the improved borrowing capacity may be worth more than the debt amount. Run the numbers for your specific situation.
