On a $150,000 gross salary in New Zealand, the RBNZ’s DTI 6x limit sets your theoretical maximum mortgage at $900,000 — assuming no other debts. Here is exactly what that means for your purchasing power, repayments, and the properties you can realistically target.
On a $150,000 gross salary with no existing debt, the DTI 6x maximum mortgage is $900,000. With a 20% deposit of $225,000, you could purchase a property up to $1,125,000. Monthly repayments on $900,000 at 5.50% over 30 years are approximately $5,110/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
A $150,000 salary is in approximately the top 5% of NZ earners. At this income level, you have strong borrowing capacity and access to most properties in every NZ market including Auckland.
Your approximate take-home pay at $150,000 gross: around $2,059/week after PAYE income tax and ACC earner levy.
Maximum Borrowing Capacity
Under the RBNZ DTI 6x rule:
| Scenario | Amount |
|---|---|
| DTI maximum mortgage | $900,000 |
| Maximum purchase price (20% deposit) | ~$1,125,000 |
| 20% deposit required | $225,000 |
| Monthly repayment (5.50%, 30yr) | $5,110 |
| Weekly repayment (5.50%, 30yr) | $1,179 |
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 $900,000 at Different Rates
| Rate | Monthly | Fortnightly | Weekly |
|---|---|---|---|
| 5.20% | $4,942 | $2,281 | $1,140 |
| 5.50% | $5,110 | $2,359 | $1,179 |
| 5.80% | $5,281 | $2,437 | $1,219 |
| 6.20% | $5,512 | $2,544 | $1,272 |
| 6.50% | $5,689 | $2,626 | $1,313 |
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 $900,000 at 8.0%, 30 years: approximately $6,604/month.
If your gross income is $150,000 and your take-home is ~$2,059/week (~$8,922/month), the stress test repayment of $6,604/month represents approximately 74% 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 $150,000?
At $1,125,000, Auckland median-area properties are within reach. You can access quality homes in Wellington, Christchurch, and Hamilton with significant choice.
25 vs 30 Year Term
On $900,000 at 5.50%:
- 30-year term: $5,110/month — total interest $939,636
- 25-year term: $5,527/month — total interest $758,036
- Saving with 25-year term: $181,600 in total interest
The 25-year term costs $417/month more but saves $181,600 in total interest. Worth considering if your income comfortably covers the higher payment.
