before financing and income tax
Planning estimate: The result excludes financing, income tax, capital growth and unexpected costs, and is not an investment recommendation.
Gross yield divides annual rent by the selected property value or cost base. It is useful for a quick comparison but does not show what remains after vacancy and operating costs.
Use a consistent cost base when comparing properties. Purchase price and total acquisition cost answer slightly different questions.
The calculator reduces rent using the occupancy assumption, then subtracts rates, insurance, management, maintenance, body-corporate and other entered costs.
The result is property-level net operating income before mortgage payments and income tax.
Assuming 100% occupancy can overstate rent. Enter a reasonable occupancy scenario based on the property and market, and test a weaker scenario rather than relying on one result.
Vacancy can also bring advertising, cleaning or letting costs that need a separate entry.
Repairs, compliance work, tenant changes, rent movements, interest rates and property values are uncertain. A high yield does not guarantee positive cash flow or a good investment outcome.
Confirm landlord obligations and tax treatment using current official guidance and professional advice where appropriate.
Use property-specific assessments, quotes and professional advice. These sources explain the New Zealand context but do not make the entered assumptions exact.
Annual gross rent is divided by the property value or selected cost base. It does not deduct vacancy, operating expenses, mortgage costs or tax.
The calculator reduces annual rent for expected vacancy, subtracts entered operating expenses, then divides the remaining annual income by the selected property value or cost base.
Common operating costs include rates, insurance, management, maintenance and body-corporate charges. Enter property-specific figures and keep financing and income tax separate.
No. The result is a simple property-level operating yield before financing and income tax. Those depend on the loan and current tax treatment.
A property may not earn rent for every week of the year. The occupancy input makes the vacancy allowance visible instead of assuming uninterrupted rent.
