Rental Yield Calculator

Estimate rental yield

Rental yield compares rental income with a property’s value or purchase price. Use this tool to explore assumptions for a Canterbury rental, then check the actual property, costs and financing. It is an operating estimate, not a forecast of profit or capital growth.

How to use the calculator

1. Enter a property value greater than zero and your expected weekly rent.
2. Enter the management fee as a percentage of rent collected after the vacancy allowance. Check the proposed fee and any GST treatment in your management agreement.
3. Enter vacancy as a percentage of the 52-week annual rent, not a number of weeks. For two vacant weeks, use approximately 3.846% (2 ÷ 52 × 100).
4. Enter annual council rates, insurance, maintenance and body corporate or other recurring costs in dollars. Use zero where a cost does not apply and avoid counting the management fee twice.

Use percentages between 0 and 100 and non-negative dollar amounts. The native tool bounds percentage calculations to this range; an out-of-range entry can remain visible, so correct the displayed input before relying on a result. Zero or negative property values do not produce a yield.

Gross and estimated net operating yield

Gross yield is weekly rent × 52, divided by property value, multiplied by 100. Estimated net operating yield first deducts the vacancy allowance, management fee on the remaining rent and the annual dollar expenses, then divides the operating income by property value.

Worked example

Illustrative inputs: property value $700,000; weekly rent $650; vacancy 3.846% (approximately two weeks); management fee 0%; total annual dollar expenses $12,000. Annual gross rent is $33,800 and gross yield is 4.83%. After vacancy, rent is approximately $32,500. Estimated net operating income is $20,500 and net yield is 2.93%. If an 8% management fee is added to those same assumptions, the fee is approximately $2,600 and net yield becomes 2.56%. These are examples, not a rental appraisal or quoted management fee.

Read the result in context

The tool’s “Monthly cash flow” label is monthly operating income before finance and tax. It does not show the money left after mortgage payments. The estimate excludes lending costs, tax, depreciation, acquisition and sale costs, major capital works and market changes. Rent and occupancy are not guaranteed. A negative net result can be legitimate when entered operating costs exceed rental income.

Use current rent evidence and actual costs or quotes. Before committing, check the property’s title, council records, insurance and relevant compliance. See Christchurch council property information, Inland Revenue rental guidance and our healthy homes resource. Seek independent advice appropriate to the property and your circumstances.
