On a $80,000 gross salary in New Zealand, the RBNZ’s DTI 6x limit sets your theoretical maximum mortgage at $480,000 — assuming no other debts. Here is exactly what that means for your purchasing power, repayments, and the properties you can realistically target.
On a $80,000 gross salary with no existing debt, the DTI 6x maximum mortgage is $480,000. With a 20% deposit of $120,000, you could purchase a property up to $600,000. Monthly repayments on $480,000 at 5.50% over 30 years are approximately $2,725/month. The bank's serviceability stress test at ~7.5-8.5% may reduce this if your living expenses are high.
Your Salary in NZ Context

Your approximate take-home pay at $80,000 gross: around $1,180/week after PAYE income tax and ACC earner levy.
Maximum Borrowing Capacity
Under the RBNZ DTI 6x rule:
| Scenario | Amount |
|---|---|
| DTI maximum mortgage | $480,000 |
| Maximum purchase price (20% deposit) | ~$600,000 |
| 20% deposit required | $120,000 |
| Monthly repayment (5.50%, 30yr) | $2,725 |
| Weekly repayment (5.50%, 30yr) | $629 |
What reduces this? Any existing debt — student loans, car loans, credit card limits — is subtracted from your DTI capacity. A $30,000 car loan reduces your maximum mortgage by $30,000. A $10,000 credit card limit (regardless of balance) reduces it by approximately $10,000.
Repayments on $480,000 at Different Rates
| Rate | Monthly | Fortnightly | Weekly |
|---|---|---|---|
| 5.20% | $2,636 | $1,216 | $608 |
| 5.50% | $2,725 | $1,258 | $629 |
| 5.80% | $2,816 | $1,300 | $650 |
| 6.20% | $2,940 | $1,357 | $678 |
| 6.50% | $3,034 | $1,400 | $700 |
Serviceability Stress Test
The DTI 6x limit is one constraint. The bank also applies a serviceability test: can your income cover the mortgage repayment at a stress-test rate of approximately 7.5%–8.5%, after all assessed living expenses?
Stress test repayment on $480,000 at 8.0%, 30 years: approximately $3,522/month.
If your gross income is $80,000 and your take-home is ~$1,180/week (~$5,113/month), the stress test repayment of $3,522/month represents approximately 69% of your net monthly income — before other living expenses. Banks benchmark total committed expenses (including mortgage) against income; where expenses are high, the actual offer may be below the DTI maximum.
What Can You Buy on $80,000?
At $600,000 maximum purchase, you’re in the Christchurch median range and can access Hamilton townhouses and outer Wellington suburbs. Auckland is limited but not inaccessible for smaller properties.
