What Is a Rental Yield?

Yield Explained

Rental yield is the amount of money your investment property generates. But what many first-time investors don’t realise is that there are multiple types of rental yield.

For instance you have the gross yield. This is the most common calculation discussed in property investor circles.

It’s worked out by taking the annual rental income and dividing it by the property’s purchase price or the current market value.


More important is the net rental yield. This takes into account not just the revenue a property generates, but also operating costs of a property.


You can do the math, or you can use a yield calculator.

A good rental yield depends on the type of property and location you’re investing in.

For instance, if investing in a growth-focussed property, like a townhouse in Auckland, target gross rental yield is between 4 - 4.75%.

However, if investing in a yield-focussed dual key apartment or a room-by-room rental in Hamilton, that should attract a rental yield in the 5.5 to 6.5% range.

The Results

After putting your information into the calculator, you’ll see a gross and a net yield amount, which is broken down further to give you an estimated weekly cash flow figure.

Let’s go through the differences.

Gross Yield

Gross yields are calculated by taking the rent your property is expected to achieve each week, multiplying it by 52 weeks to get the potential annual rent, and then dividing that figure by the purchase price or value of your property.

They're easy to calculate (which is why you'll often see them mentioned and reported in the media) but for an individual property investor looking at a particular investment, a gross yield is not very useful.

Why? Because a property might attract a lot of revenue as a proportion of the purchase price, but it could actually cost you money each week. This would happen if the costs associated with the property, e.g. maintenance, are also very high.

For example, if you invested in a run-down property in an area where property prices are cheap, it will likely get a high gross yield. But if the hot water cylinder bursts, there are ongoing maintenance issues, or the property is structured on a principal and interest loan, it could well be cash-flow negative.

Net Yield

With all the above limitations considered, it makes sense to pay attention to the net yield of an individual property.

It’s what your cash flow would be, after all your operating expenses, but before your mortgage expenses.

Operating expenses include rates, insurance, property management and maintenance. But it excludes the financing costs of your mortgage.

The net yield figure is much more useful when comparing properties because while your finance costs will be very similar, your operating expenses can vary widely between properties.

The apartments are expected to earn the same amount in rent, but one has a higher body corporate than the other.



When Making Calculations, Should I Use Purchase Price Or Current Value?


To work out the rental yield, you need to use the properties purchase price / current value of the property.

There is an argument in property investment circles about whether to use the price you paid for the property or the price it’s actually worth.

We recommend using the current market value of a property.

The reason for this is that house prices change. It doesn’t matter what the property was worth 10 years ago: you want to know the yield of the money you’ve got invested today.

For instance, if you bought an apartment for $275,000 in 2011 and rented it for $300 a week, it would attract a gross yield of 5.67%.

Let’s now say that over the last 10 years the property has doubled in value and is now worth $550k. Now let’s say that over that period the rent stayed the same.


If you calculate gross yield based on the original purchase price, the yield would still be 5.67%.

But calculate the yield based on current value and the property attracts a yield of 2.84%.

That’s below our acceptable yield range for an apartment (4.5% - 5.5%). This would raise alarm bells for savvy investors, who would immediately seek to increase the rent because the property is under-rented.

But if you had used the original purchase price as your guide you could have missed this.
