NZ Rental Yield Calculator

Enter a property price and expected rent to see gross yield. Add typical NZ ownership costs — rates, insurance, property management, maintenance — to calculate net yield and cashflow position.

How this calculation works

Gross yield = annual rent ÷ purchase price × 100. Net yield = (annual rent − holding costs) ÷ purchase price × 100. Holding costs include council rates, insurance, property management fees (typically 7–10% of rent), and maintenance allowance (typically 5–15% of rent). Mortgage costs are calculated separately to show cashflow position. Interest-only repayments shown when selected.

When to use this

  • Comparing investment properties by yield before making an offer
  • Stress-testing whether rental income covers ownership costs
  • Understanding cashflow position with principal + interest vs interest-only
  • Comparing gross vs net yield to avoid underestimating costs

Important limitations

  • Does not include tax implications (ring-fencing, interest deductibility phase-in)
  • Does not include one-off purchase costs (legal, LIM, building inspection)
  • Does not account for vacancy periods (budget 2–4 weeks per year)
  • Brightline test may apply on resale — calculate separately

Common questions

What's a good rental yield in NZ?

Gross yields of 3–5% are common in main centres (Auckland, Wellington). Regional yields of 5–7% are achievable. Net yield is what matters — costs can be $5,000–$10,000+ per year before mortgage.

Can I claim mortgage interest as an expense?

Interest deductibility for residential investment properties is being phased back in. As of April 2024, 80% is deductible, rising to 100% from April 2025. This calculator shows pre-tax cashflow only — consult a tax professional.

Is interest-only still available for investors?

Yes, but banks assess serviceability on a P&I basis regardless. Interest-only terms are typically limited to 5 years before reverting to P&I.
