The standard affordability rule is that rent should be no more than 30% of your take-home (after-tax) income. In Auckland and Wellington, many renters spend 35–40%. Use this calculator to find your personal threshold.
On a $70,000 salary (~$4,450/month take-home), the 30% rule allows $1,335/month or $308/week in rent. Auckland median rent (2025) is approximately $650/week for a 3-bedroom house — requiring a household income of $108,000+ to stay within the 30% guideline. Flatting lowers the per-person cost: two people sharing that $650/week property pay $325/week each.

The Auckland Rent Reality
The 30% rule was developed for US markets where housing costs are lower relative to income. In Auckland:
- Median rent for a 3-bedroom house: ~$640/week ($2,773/month)
- At 30% rule: Requires ~$2,130/week take-home (~$110,000 gross for a single person)
- Auckland median household income: ~$120,000 (couple) — barely within the 30% rule
- Single renter on average salary ($70,000): Can afford ~$400/week at 30% — needs a flat or 1-bedroom
Flatting remains the primary affordability lever in Auckland. Sharing a $640/week 3-bedroom with two others means each person pays ~$213/week — well within any affordability target.
What Happens When Rent is Above 30%?
Spending 35–40% on rent is common in Auckland and Wellington, but creates financial constraints:
| Rent as % of income | After-rent budget pressure |
|---|---|
| 25% | Comfortable — good savings potential |
| 30% | Standard — manageable with discipline |
| 35% | Tight — limited savings capacity |
| 40% | Stressed — difficult to save meaningfully |
| 45%+ | Housing stress — may qualify for Accommodation Supplement |
