Estimated borrowing capacity for a $50K 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 | $215,422 | $1,362/mo | $269,277 |
| Single, no kids, with HECS | $194,708 | $1,231/mo | $243,385 |
| Couple (equal income), no kids | $629,695 | $3,980/mo | $787,118 |
| Couple, 2 kids | $405,987 | $2,566/mo | $507,484 |
| Single, 1 kid | $165,709 | $1,047/mo | $207,136 |
Single on $50K: Maximum borrowing of approximately $215,422. With a 20% deposit, this supports a property budget of around $269,277.
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% | $269,277 | $787,118 |
| 10% | 90% | $239,358 | $699,661 |
| 5% | 95% | $226,760 | $662,837 |
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 $50K salary, the compulsory HECS repayment rate is approximately 4% of your income, which is $2,000 per year or $167/month. This reduces maximum borrowing by approximately $20,714 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.
