Key points
Rental yield formulas
Gross yield = annual rent ÷ property value or purchase price × 100.
Net yield = annual rent after vacancy and operating expenses ÷ the chosen property cost basis × 100.
Yield excludes some financing and tax effects, so it should be considered alongside cash flow, risk and total return.
Gross yield and net yield on the same property
For a $650,000 property earning $650 a week, vacancy and operating costs—not optimistic rent—create the meaningful difference.
| Check | Annual amount | Yield on $650,000 |
|---|---|---|
| Scheduled gross rent | $33,800 | 5.20% gross |
| Less two vacant weeks | $32,500 received | 5.00% before costs |
| Less $9,500 operating costs | $23,000 net operating income | 3.54% net |
| Mortgage cash flow | Calculate separately | Not the definition of property yield |
How to calculate gross rental yield
Multiply weekly rent by 52 to estimate annual scheduled rent, then divide by the purchase price or another clearly labelled value basis and multiply by 100.
Gross yield is fast for screening but ignores vacancy, rates, insurance, maintenance, management and compliance. Use the same basis when comparing properties.
How to calculate net rental yield
Estimate rent actually received after vacancy, then subtract operating expenses such as rates, rental insurance, maintenance, management and eligible body-corporate costs. Divide the net operating income by the stated property basis.
Keep assumptions visible. A favourable net yield created by unrealistically low vacancy or maintenance allowances is not a reliable comparison.

Yield versus mortgage cash flow
Property yield usually measures the property before financing. Mortgage interest and principal payments affect investor cash flow, while principal repayment also changes equity.
A property can show positive net operating yield and still require weekly cash contributions after financing. Conversely, a large deposit can improve cash flow without changing the property’s underlying gross yield.
What counts as a good rental yield
There is no universal good percentage across New Zealand. Location, property type, condition, tenant demand, expected costs, financing, concentration risk and potential capital changes all matter.
Use yield to compare consistent scenarios, then investigate the property and tenancy assumptions. Do not rely on an advertised regional average as a promise for one address.
Frequently asked questions
How do I calculate rental yield in NZ?
Divide annual rent by the chosen property value or cost and multiply by 100. Deduct vacancy and operating expenses first for net yield.
What is the difference between gross and net yield?
Gross yield ignores expenses; net yield deducts stated vacancy and operating expenses before calculating the percentage.
Does rental yield include mortgage payments?
Usually not. Financing belongs in a separate cash-flow analysis so properties can be compared independently of deposit size.
What is a good rental yield in New Zealand?
There is no universal benchmark. Compare similar properties using realistic net expenses, risks and financing.
