Rental yield is one of the first numbers any property investor learns, and one of the most commonly misused. The problem is that most people quote gross yield, the flattering version, and get an unpleasant surprise when the real costs come out. Understanding the difference between gross and net yield, and calculating the right one, is fundamental to investing well. Here’s the plain-language guide. [PUBLISHING NOTE: general education, not financial or investment advice; yield benchmarks shift with the market.]
What Rental Yield Is
Rental yield is the annual rental income a property generates, expressed as a percentage of its value. It tells you how hard your money is working as income, separate from any capital growth (the increase in the property’s value over time).
In simple terms, it answers: for the money tied up in this property, how much rent does it produce each year? A 5 per cent yield means the annual rent equals 5 per cent of the property’s value. Higher yield means more income relative to price; lower yield means less.
Gross Yield, the Flattering Version
Gross yield is the simple, headline number, and the one most people quote. You calculate it by dividing the annual rent by the property value, then multiplying by 100.
For example, a property worth $600,000 that rents for $575 a week earns $29,900 a year. Divide $29,900 by $600,000 and multiply by 100, and the gross yield is about 5 per cent. It’s quick and easy, which is exactly why it’s so widely used, and so misleading. Because it ignores every cost of actually owning the property.
Net Yield, the Honest Version
Net yield is the number that actually matters, because it accounts for the costs. You take the annual rent, subtract the annual expenses of owning the property, then divide by the property value and multiply by 100.
Those expenses add up: council rates, water rates, insurance, property management fees (typically 5 to 8 per cent of rent), maintenance and repairs, strata or body corporate fees if it’s an apartment, and periods when the property sits vacant between tenants. On our $600,000 example, if those costs total, say, $7,000 a year, the net rent is $22,900, and the net yield drops to about 3.8 per cent, well below the 5 per cent gross figure.
That gap between gross and net is exactly where investors get caught out. A property advertised as a “5 per cent yielder” might really return under 4 per cent once you own it, and that difference is the money you actually keep.
Why This Matters So Much
The reason net yield is critical is that it determines your actual cash position. If you’re borrowing to invest, the question that matters is whether your net rental income covers your mortgage repayments and holding costs, or whether you’re topping it up out of your own pocket each month.
In a higher interest rate environment like the present, this is make-or-break. If your net yield is 3.8 per cent but your mortgage rate is 6 per cent, the property costs you money to hold every week (negative cash flow). If you’d only looked at the 5 per cent gross figure, you might have badly underestimated that shortfall. Always work out the net figure before you buy, because it’s the difference between an investment that sustains itself and one that drains you.
Yield Is Still Only Half the Story
Even net yield doesn’t tell the whole story, because total return is yield plus capital growth. A property with a modest net yield but strong capital growth can outperform a high-yield property whose value barely moves, and vice versa.
There’s a well-known trade-off: high-yield areas (cheaper suburbs, regional areas, units) often have lower capital growth, while high-growth areas (blue-chip capital-city suburbs) often have lower yields. Neither is automatically better, it depends on your strategy and goals. The point is to weigh both, using accurate net yield, not flattering gross yield, alongside realistic growth expectations.
How to Use Yield Wisely
Practically: always calculate net yield, not just gross, for any property you’re considering. List every cost honestly, including a vacancy allowance and maintenance. Compare the net yield against your borrowing costs to understand your real cash position. Weigh it alongside the area’s capital growth prospects and your own goals. And remember that a property you can comfortably afford to hold is far less stressful than a high-headline-yield property that drains you each month.

The Bottom Line
Gross yield is the flattering headline number; net yield, after all the costs, is the one that actually reflects what you keep, and it’s usually well below the gross figure. Most investors get caught out by quoting gross and ignoring the costs that turn a “5 per cent yielder” into a sub-4 per cent reality. Always calculate net yield, compare it to your holding costs, and weigh it alongside capital growth. Get that right, and you’ll invest on real numbers rather than flattering ones. This is general information, not financial or investment advice, and professional advice is worthwhile before investing.
