Whether you’re considering your first investment property or comparing your next one, if you’re an investor, understanding rental yield is one of the most practical things you can do.

TL;DR Gross yield is a good starting point, but net yield (which factors in costs like management fees, insurance and maintenance) will give you a much more accurate idea around how a property is actually performing. There's no magic number that makes a yield "good" - it depends on your goals and what similar properties in the same area are doing. The important thing is using realistic rent figures, not relying on gut-feel, and always comparing ‘apples with apples’. |
You’ve found a property that looks promising. The suburb is growing, the rent seems pretty solid and the price feels right.
But before you commit to anything, there’s one number worth getting your head around: rental yield.
So how do you calculate rental yield… and why does it matter?
It matters because this one figure alone tells you how much rental income a property generates relative to what it costs – plus, it’s one of the quickest, most practical, ‘apples-with-apples’ ways to compare investment properties.
Once you understand how it works (and what to do with the result), it will change the way you assess every property you look at.
What is rental yield?
Rental yield, in its simplest form, is the annual rent a property earns, expressed as a percentage of its purchase price or current market value.
For example, if you buy a property for $630,000 and it brings in $33,800 a year in rent, the rental yield is around 5.4%.
That percentage tells you how efficiently the property is generating income relative to what you paid for it.
It doesn’t capture every cost involved in owning the property - but it gives you a reliable starting point for comparing options and judging whether the rent makes sense for the price.
But it’s important to note that there are two types of yield that matter: gross yield, which looks at rent alone, and net yield, which factors in your main ongoing costs.
We’ll cover both shortly.
Why does rental yield matter for investors?
Rental yield is useful because it turns a subjective gut-feeling about a property’s income potential into a concrete number you can easily compare across properties, suburbs and price points. Plus:
- It helps you measure income against price. A yield figure tells you whether the rent level makes financial sense for what you’re paying. Two properties might both rent for $550 a week, but if one costs $500,000 and the other $700,000, the returns are very different.
- It helps you compare properties quickly. When you’re weighing up a townhouse in one suburb against an apartment in another, yield gives you a common measure to more easily assess them side by side.
- It can flag pricing concerns. A very low yield might mean you’re paying a premium price for the rent on offer. A very high yield might look attractive, but could signal higher vacancy risk, ongoing maintenance issues or weaker tenant demand. Neither is automatically better - it depends on what you’re trying to achieve.
- It connects to your investment strategy. Some investors prioritise higher-yield properties to support cash flow now. Others accept a lower yield in a location with stronger long-term capital growth potential. Yield helps you match a property to your goal.
It’s also worth noting that rental yield estimates tend to be more reliable when the rent and running costs are based on comparable properties of comparable age and condition, and with similar features - which makes doing your research on the local market especially important.
How to calculate rental yield (gross and net)
Calculating rental yield isn’t complicated. You only need a few figures, and your phone calculator will do the job.
- Step 1: Work out your annual rent
Take the expected weekly rent and multiply it by 52. For example, if the property rents for $650 per week: $650 × 52 = $33,800 per year. This annual figure becomes the foundation of both calculations. - Step 2: Decide which property figure to use
If you’re assessing whether to buy, use the purchase price. If you already own the property and want to measure current performance, use today’s market value. - Step 3: Calculate gross yield
Gross yield = (annual rent ÷ purchase price) × 100
Using: ($33,800 ÷ $630,000) × 100 = 5.4%
Gross yield is handy for quick comparisons, but because it ignores costs of ownership, it can make a property look stronger than it is. So treat it as a starting point, not the be all and end all. - Step 4: Calculate net yield
Net yield = [(annual rent - annual cost) ÷ purchase price] × 100
Net yield gives you a much more realistic picture because it accounts for the actual cost of owning and maintaining the property.
These costs typically include property management fees, council rates, landlord insurance, strata or body corporate fees (if applicable), a maintenance allowance, letting fees when tenants change and an allowance for any potential vacancy periods.
For example: Let's say your $630,000 property earns $650 per week ($33,800 annually) and your estimated annual cost break down as follows: property management fees $2,700, council rates $1,400, landlord insurance $1,200, maintenance allowance $800 and letting/vacancy costs $1,200 - totalling around $7,300.[($33,800 − $7,300) ÷ $630,000] × 100 = 4.2% net yield
That’s a 1.2% difference from the gross figure - across a full year and beyond, that gap can have a real impact on your cash flow
How to estimate realistic rent
Your yield calculation is only as good as the rent figure you put into it. If you overestimate the rent, the yield will look far better than reality - and that can lead to a costly misstep.
The most reliable approach is to get two or three rental appraisals from local property managers who know the area well. They’ll give you a realistic range based on what similar properties are leasing for right now.
You can also do your own research by checking current rental listings on sites like Domain or realestate.com.au.
Look for properties with a similar number of bedrooms and bathrooms, in similar condition, with comparable features like parking, air conditioning and outdoor space. Also pay attention to what’s been leased recently, not just what’s being advertised – that’s because asking rents and achieved rents aren’t always the same.
It’s also wise to factor in a contingency for vacancy periods. Even well-located properties will have gaps between tenants occasionally, so allowing for a couple of weeks each year keeps your figures reasonably accurate.
Purchase price yield vs market value yield
When calculating yield, you can use either the purchase price or the property’s current market value.
But which do you use, when? A simple rule of thumb is to use the purchase price when you’re deciding whether to buy.
It tells you what your return will be based on what you’re about to pay, and it’s the most useful figure for comparing options.
Once you own the property, switching to current market value gives you a better read on how your investment is performing today.
If the property has risen in value since you bought it, the yield based on market value will naturally be lower - even if the rent hasn’t changed. But don’t worry - that’s not a concern. It’s simply capital growth doing what it does best.
For the most up-to-date market rent data in SA, the Private Rent Report on Data SA provides quarterly median rents by suburb and postcode, based on bonds lodged with Consumer and Business Services.
So, what is a good rental yield?
This is one of the most common questions investors ask, and the honest answer is: it depends.
There isn’t a single number that suits every property, every location or every strategy.
A 3.5% gross yield in a tightly held Adelaide Hills suburb might be perfectly reasonable if you’re investing for long-term capital growth, while a 6% yield in a regional centre might suit someone focused on cash flow - but it could also reflect higher vacancy risk or ongoing maintenance costs.
The most useful approach is to compare similar properties in the same area and in similar condition. That way, you’re measuring like against like, and any differences in yield become meaningful rather than misleading.
If a yield looks unusually high or unusually low compared to similar properties nearby, it’s worth digging a little deeper and asking why.
The answer will often tell you more about the property’s risk profile than the yield number itself.
What influences rental yield?
If yield varies so much between properties, what’s driving those differences? It usually comes down to three things.
- Rent level. This fluctuates by location, tenant demand, the condition and features of the property and what comparable rentals in the area are achieving. Homes close to transport, schools, shops and employment hubs generally attract more stable, competitive rents.
- Property value. Yield is a ratio, so property price directly affects the result. If prices rise faster than rents in an area, yield will fall - even if the rent itself hasn’t changed.
- Costs. Council rates, insurance, strata fees, property management, maintenance and vacancy periods all reduce net yield. Properties with higher ongoing costs will naturally show a lower net return.
How to improve your rental yield?
If your yield isn’t quite where you’d like it to be, there are two levers you can pull: increase the rent, or reduce costs.
On the ‘increase rent’ side:
Make sure your rent is set based on actual market evidence, not gut-feel. Check what comparable properties in the area are achieving and adjust accordingly. Present the property well so it rents quickly, and focus on features that tenants are willing to pay for - these vary by location and demographic, so do your research.
On the ‘reduce cost’ side:
Look for ways to lower tenant turnover, since every changeover brings letting fees and vacancy. Respond to maintenance requests promptly, review your insurance and management fees periodically and plan to complete maintenance and repairs before they turn into emergencies. If you’re considering renovations, check what other renovated rentals in the same area are achieving before spending anything - the uplift in rent needs to justify the outlay.
Some investors also find that choosing a new, or freshly renovated property that’s ready to rent from the start avoids the weeks of lost income that can come with renovating or repairing before a tenant moves in. This is often what makes new and off-the-plan properties so attractive to investors.
Making rental yield work for you?
Rental yield is one of the simplest tools available to property investors, but the difference between using it well and using it unwisely can be significant.
Our biggest tip? Work out net yield wherever possible, don’t simply rely on gross.
Base your rent estimate on proper appraisals, research and comparable listings, not the latest news headlines.
Include the main annual costs and an allowance for vacancy. And always compare like with like - similar properties, in similar condition, in the same area.
But most importantly, make sure the property you’re considering fits your goal.
If steady rental income is your priority, a higher-yielding property may serve you better. If you’re focused on growing long-term wealth, a lower yield in a growth suburb might make more sense.
The investors who tend to do well aren’t the ones chasing the highest number. They’re the ones who understand what the numbers mean in context, and use that understanding to make clearer, more confident (and smarter!) decisions.
