Gross vs Net Rental Yield: The Number Landlords Don't Advertise
The listing said "6.8% gross yield, tenant in situ, no chain." I was scrolling buy-to-let flats near Manchester on a Tuesday night, and that number was printed bigger than the asking price. £142,000 for a two-bed, £805 a month in rent — the maths on the page checked out. It felt like exactly the kind of deal every property forum told me to look for.
Then I actually ran it through a spreadsheet instead of trusting the agent's headline figure. Letting agent management fees at 12%, landlord insurance, a gas safety certificate and EPC renewal, a realistic six-week void between tenancies, and £900 a year set aside for maintenance on a building that age. The 6.8% "yield" on the listing dropped to a net yield of 3.9% — nearly half of what was advertised, on the exact same flat.

What Is Rental Yield and Why Do Gross Numbers Lie?
Rental yield is the annual rental income a property generates, expressed as a percentage of what it cost to buy. It's the headline number used to compare very different properties — a studio flat and a five-bed house — on a level footing, the same way a dividend yield lets you compare shares of wildly different prices.
The catch is that "rental yield" almost always gets quoted as a gross figure, because gross is the bigger, better-looking number. Gross yield only asks one question: how much rent does this property bring in versus what I paid? It doesn't ask what it costs to actually run the thing. Management fees, insurance, safety certificates, service charges, and the weeks a property sits empty between tenants are all invisible in a gross figure — which is exactly why the listing agent's flyer leads with it.
Key Takeaway
A gross yield printed on a listing is a marketing number, not an underwriting number. It tells you nothing about what the property actually pays you once running costs are subtracted — always rebuild the net figure yourself before comparing two deals.
How Do You Calculate Gross and Net Rental Yield?
Both versions start from the same two inputs — annual rent and total investment — and the formulas are short enough to do on a phone calculator, though a dedicated Rental Yield Calculator saves you from re-typing the same sums for every listing you compare.
Total investment is not just the purchase price. It's the purchase price plus every up-front cost of acquiring the property — stamp duty (or transfer tax), legal fees, survey costs, and any immediate refurbishment before the first tenant moves in. Skip this step and you'll overstate every yield you calculate.
Here's that Manchester flat again, worked in full:
| Line item | Amount |
|---|---|
| Purchase price | £142,000 |
| Stamp duty + legal + survey | £6,400 |
| Total investment | £148,400 |
| Annual rent (£805 × 12) | £9,660 |
| Letting agent fees (12%) | £1,159 |
| Insurance, gas safety, EPC | £480 |
| Maintenance reserve | £900 |
| Void allowance (6 weeks) | £930 |
Gross yield: £9,660 ÷ £148,400 = 6.51% — already a touch lower than the advertised 6.8%, because the agent's flyer used the purchase price alone, not the total investment including buying costs.
Net yield: (£9,660 − £1,159 − £480 − £900 − £930) ÷ £148,400 = £6,191 ÷ £148,400 = 4.17%
That's the honest number. In US dollars, the same shape of gap shows up on an American rental: a $310,000 duplex renting for $2,600/month looks like a 10.1% gross yield, but $850/month in property management, insurance, taxes, and a realistic vacancy allowance brings the net figure down to roughly 6.4% — still solid, but a very different pitch than the one on the listing.
💡 Pro Tip
Build your expense list from real quotes, not guesses. Call a local letting agent for their actual management fee, get an insurance quote for the specific property, and ask what similar units in the building typically sit empty for between tenancies. A net yield built on real numbers is the only version worth trusting.
What's a Good Rental Yield in 2026?
There's no single "good" yield — it depends on the market, the asset, and what you're optimising for. A lower yield in a prime location usually trades income for stronger long-term capital growth; a higher yield in a secondary market usually compensates for slower growth and a more hands-on tenant base.
The UK's National Residential Landlords Association (NRLA) and property portals such as Rightmove and Zoopla routinely put average UK gross rental yields somewhere between 4% and 7%, with the highest figures concentrated in the North of England and the lowest in inner London. In Australia, the property data firm CoreLogic tracks gross rental yields that typically run higher in regional areas than in capital cities, where high purchase prices compress the income return relative to the asset value.
| Market | Typical gross yield | What it usually reflects |
|---|---|---|
| Prime city centres (London, Sydney, NYC) | 3–4.5% | Lower income return, priced for capital growth |
| Growing regional cities | 5–7% | Balance of income and appreciation |
| Smaller / higher-risk markets | 7%+ | Higher income, more management effort |
A net yield above roughly 4% is generally considered workable in most developed rental markets once financing costs are factored in separately, though landlords with a mortgage should compare their net yield directly against their interest rate — a net yield below the mortgage rate means the rental income alone isn't covering the cost of the debt, before accounting for any capital appreciation.
⚠️ Note
Rental yield says nothing about capital growth or the direction of house prices. A property with a modest 3.5% net yield in a fast-appreciating area can easily outperform a 7% yield in a stagnant one over a five- or ten-year hold — yield is one input to the decision, not the whole decision.
Is Rental Yield the Same as Cap Rate?
Not quite, though they're built from the same idea. "Rental yield" is the term used most often in the UK and Australia, and it's frequently quoted as a gross figure — rent over price, no deductions. "Cap rate," the term US investors use, is built from net operating income (NOI) by convention, which makes a US cap rate closer to a net yield than a gross one. We've covered that side of the comparison, including how cap rate interacts with financing, in the Cap Rate Calculator guide.
The practical lesson: when you see "yield" or "cap rate" on a listing anywhere in the world, the first question is always the same — is this gross or net? A 7% figure that turns out to be gross once you dig in is not comparable to a 6% figure that's already net of expenses. The net number is always the smaller, more honest one, and it's the only one worth using to compare two different properties against each other.
An Australian investor comparing a Brisbane unit at A$540,000 renting for A$560/week (A$29,120/year) gets a gross yield of 5.39%. Once A$110/week body corporate fees, A$650 insurance, and an 8% property management cut are factored in, the net yield lands closer to 3.6% — the same story, in a third currency, on a different continent.
Frequently Asked Questions
What counts as a good rental yield in 2026?
Above roughly 5% gross is generally considered strong in most developed rental markets, 3–5% is common in major cities where buyers are paying a premium for long-term capital growth, and below 3% usually only makes sense if you're confident the area will appreciate significantly. On the net side, aim for a figure that comfortably clears your mortgage interest rate if the property is financed.
Should mortgage payments be included in net yield?
No. Net yield deducts operating expenses — management fees, insurance, maintenance, and a vacancy allowance — but not mortgage principal or interest. This keeps yield a measure of the property's own performance, independent of how any individual buyer chooses to finance it, the same way a cap rate assumes an all-cash purchase. Compare your net yield against your mortgage rate separately to see whether financing helps or hurts your return.
How does a void period affect rental yield?
Every week a property sits empty between tenants reduces your effective annual rent. A six-week void on a property let for the rest of the year still costs you roughly 11.5% of your expected annual income. Experienced landlords build a vacancy allowance of 4–8% into their net yield calculation rather than assuming 100% occupancy, which is what most advertised gross yields quietly assume.
Is rental yield the same as cap rate?
They're close cousins built from the same logic. Rental yield is the term used in the UK and Australia and is often quoted gross (no expenses deducted); cap rate is the US term and is built from net operating income by convention, making it closer to a net yield. Always confirm whether a quoted figure is gross or net before comparing it across markets or terminology.
Does rental yield account for capital growth?
No — yield measures income return only. Total return on a rental property combines yield with capital appreciation (or depreciation) in the property's value over your holding period. A property with a lower yield in a high-growth area can still outperform a higher-yielding property in a flat or declining market once both income and price movement are counted.
Try It Yourself
An advertised yield is a marketing number until you rebuild it with real expenses, a realistic void allowance, and your actual buying costs included. The gap between gross and net is exactly where most rental deals stop looking as good as the flyer promised.
