Rental Yield Calculator
Use this to screen a property fast. Enter rent, price, and annual operating expenses to see gross and net yield, annual net operating income, and how much expenses are dragging on the property-level return. Then layer financing and tax on top separately.

Gross yield = annual rent divided by property price, then multiplied by 100. Net yield = annual rent minus annual operating expenses, divided by property price, then multiplied by 100. This is useful for screening, but it is not the same thing as cash flow after debt or after tax.
Yield dashboard
Screen the property before you build a full ROI model
Yield is the fast filter. It tells you how much rent the property throws off relative to its value and how much of that is lost to operating costs. It does not tell you whether the mortgage structure or tax treatment still makes the deal work.

Tax context
New Zealand reminder
New Zealand: residential rental losses are ring-fenced. If mortgage interest pushes the property into a net loss, that loss is quarantined and carried forward to offset future rental profits.
Yield is not an after-tax return. If the decision depends on debt, loss treatment, or sale timing, use the ROI calculator and the tax comparison guide together.
Next step
When yield is not enough, move to ROI
A property can screen well on gross or net yield and still fail once debt service, hold period, growth assumptions, and exit costs are added. Use the ROI calculator when financing structure or timing matters to the decision.
How to calculate rental yield
- Annual rent: multiply weekly rent by 52. A property renting for NZ$650 per week produces NZ$33,800 per year before costs.
- Gross yield: divide annual rent by the property price, then multiply by 100. NZ$33,800 divided by NZ$850,000 gives about 3.98%.
- Annual operating expenses: add rates, insurance, property management fees, maintenance, and similar recurring costs. Do not include mortgage interest in a yield calculation.
- Net yield: subtract annual operating expenses from annual rent, divide by the property price, then multiply by 100. This tells you what the property is generating before financing.
- Interpret it in context: if the property still looks attractive on net yield, then test debt service, hold period, and exit assumptions in the ROI calculator.
Frequently asked questions
- What is gross rental yield?
- Gross rental yield is the annual rent a property generates, divided by the property's price or market value, expressed as a percentage. It ignores operating expenses, mortgage interest, tax, and vacancy, so it is useful for quick comparisons but not a complete measure of return.
- What is net rental yield?
- Net rental yield is annual rent minus annual operating expenses, divided by the property's price or market value, expressed as a percentage. It still excludes mortgage interest and income tax, so it is the property's operating return, not the investor's after-tax return.
- Why are New Zealand and Australian yields not directly comparable?
- Yield conventions differ. New Zealand investors often quote gross yield on purchase price, while Australian investors may quote yield on current market value. The tax treatment of rental losses also differs materially: New Zealand ring-fences residential rental losses, while Australian negative gearing can let a net rental loss offset other assessable income in the same year.
- Does this calculator include tax, mortgage interest, or capital gains?
- No. This calculator is deliberately property-level only. It does not model income tax, mortgage interest, capital gains tax, the New Zealand bright-line test, or depreciation schedules. Use a fuller ROI model and qualified tax advice for after-tax decision-making.
