Gross Yield vs Net Yield Explained for UK Property Investors

Gross yield vs net yield is one of the most commonly searched, and most commonly misunderstood, comparisons in property investment. Yield sits at the top of a brochure, headlines a marketing email, and gets quoted confidently on a call. The trouble is, yield on its own tells you very little unless you know exactly what’s being measured, and most figures in circulation are gross, not net.

Understanding the difference between gross yield and net yield isn’t just a technical exercise. It’s the difference between comparing developments accurately and comparing them on a number that’s been chosen because it looks good.

This guide covers how to calculate both, two worked examples with real costs, how short-term letting changes the picture, and the two figures that matter even more than yield when you’re deciding whether a property is worth buying.

Gross Yield vs Net Yield: What Gross Yield Actually Is

Gross yield is the simplest calculation in property investment, and the easiest to misuse. Here’s how to calculate rental yield on a gross basis:

Gross yield = (annual rent ÷ purchase price) × 100

For example, a property bought for £200,000 and let for £1,000 a month (£12,000 a year) has a gross yield of 6%.

That’s the whole calculation. Nothing is deducted: no costs, no void periods, no fees. It’s useful for a quick comparison between properties, but it isn’t a measure of what you’ll actually receive. It’s also the number most often used in marketing, because it’s the highest one available.

Gross Yield vs Net Yield: What Net Yield Accounts For

Net yield starts from the same place, annual rent against purchase price, but deducts the running costs of actually holding and letting the property:

Net yield = ((annual rent − annual costs) ÷ purchase price) × 100

The costs that should be included are:

• Property management fees: typically 10% to 15% of rent if the property is fully managed
• Service charges: apply to most apartments and vary significantly by development
• Mortgage interest: if the purchase is financed rather than cash. Our guide to buy to let mortgage rates covers where rates currently stand
• Insurance: both buildings and landlord cover
• Maintenance and repairs: which vary considerably with the property’s age and condition
• Void periods: the weeks a property sits empty between tenancies, commonly 4 to 8 weeks a year

Does Net Yield Include Mortgage Interest?

There’s no single, universally accepted definition of net yield. Some investors and institutions calculate it before finance costs, treating mortgage interest separately. Others, including us, include it, because it’s a real cash cost for most buy-to-let purchases. Neither approach is wrong, but always check which one you’re looking at when a net yield is quoted, as the gap between the two can be substantial.

Once running costs are deducted, net yield before financing is typically 1 to 3 percentage points lower than the gross figure. Add mortgage interest, and the gap between gross yield vs net yield can be much larger, as the worked examples show.

Gross Yield vs Net Yield: Two Worked Examples

Example 1: A Two-Bedroom Apartment at £250,000

The apartment lets for £1,300 a month (£15,600 a year) and is bought with a typical 75% loan-to-value buy-to-let mortgage (a £62,500 deposit), interest-only at 5%. We’ve used a conservative maintenance estimate of £1,000 a year, reflecting a newer apartment; older properties, or houses rather than flats, should budget considerably more.

That’s the real gap between gross yield vs net yield in practice: an advertised 6.24% can shrink to well under 1% once a realistic mortgage sits alongside running costs.

That isn’t a sign the investment doesn’t work. It’s the reason rental yield alone is the wrong metric once borrowing is involved. At this level of gearing, the case for the investment rests far more on capital growth and total return than on rental margin in the early years, which we cover below.

Example 2: A One-Bedroom Apartment at £188,000

The apartment lets for £950 a month (£11,400 a year), with a 75% LTV mortgage (£141,000) at 5% interest.

Investors putting down a bigger deposit, or buying with cash, will see a much stronger net yield, because mortgage interest is the single biggest cost in both examples. We’ve used 75% LTV because it’s the most common buy-to-let structure according to UK Finance lending data, but always run your own numbers using your actual deposit and mortgage terms. With many buy-to-let fixes priced between 5% and 6% in late 2026, it’s worth stress-testing at a higher rate too.

How Investors Improve Net Yield

The examples above are deliberately conservative: a high-borrowing, standard-let scenario. In practice, investors have several levers to pull. Here’s how the same one-bed apartment’s net yield changes:

A few of the most effective levers:

• Borrow a little less. Every extra pound of deposit reduces the biggest cost line. Our guide to how much capital you need to invest in property helps you find the right balance.
• Choose developments with short let approval in locations that support it, which can transform the income side (more on this below).
• Buy new build. Lower maintenance, warranties and modern energy efficiency keep running costs down, year after year.
• Buy where demand is strong, so voids stay minimal and rents keep rising over time, which steadily lifts your yield on the price you originally paid.

This is exactly the thinking behind the developments we select.

The same apartment can produce anything from under 1% to nearly 6% net, depending on how it’s financed and let. Illustrative figures only.

A Note on Void Periods

Void periods are a standard cost in most net yield models, typically 4 to 8 weeks a year. We don’t build a void allowance into our own figures, because the developments we select are chosen specifically for strong, consistent rental demand: close to transport, employment and regeneration, rather than in areas where finding a tenant is a genuine risk.

That’s a judgement based on location fundamentals, not an assumption that voids never happen. It’s worth asking any provider whether their figures include a void allowance, and if not, why not. The answer should rest on real demand evidence for that location, not on making the number look better. The ONS private rents data is a useful starting point for checking rental demand in an area.

How Short-Term Letting Changes Net Yield

The examples above use standard assured shorthold tenancy (AST) rent, the model most net yield calculations default to. It’s a fair baseline, but it isn’t the only option on many of the developments we work with, several of which are in locations strong enough to support short-term letting (STL).

Take the same one-bedroom apartment at £188,000. At a modest illustrative nightly rate of £115 and 80% occupancy (292 nights a year), gross short-term let income is around £33,580, compared with £11,400 on a standard AST.

In the right locations, short-term letting can materially improve returns. But higher income comes with more operational complexity, occupancy that varies through the year, and local regulations that differ by council. It isn’t a simple substitute for AST income everywhere, and the AST figures above remain the conservative baseline every investor should understand first. Our comparison of short term lets vs long term lets covers the trade-offs in more detail, and developments with short let approval, such as St George’s Terrace in York and No5 Guildhall in Norwich, show what this looks like in practice.

Gross Yield vs Net Yield: Why Neither Tells the Whole Story

Even net yield, done properly, only tells you about income. It says nothing about what happens to your capital. Two figures matter more than yield alone when you’re assessing a genuine investment case.

1. Cash-on-Cash Return

This measures your net rental income against the actual cash you’ve put in, not the full purchase price. For a mortgaged purchase, it usually reflects your real return on the money you’ve committed far better than either yield figure.

Using Example 2: the one-bed produces £832 a year of net income on a standard AST. Against the full £188,000 price, that’s a 0.44% net yield. Against the £47,000 deposit actually invested, it’s a cash-on-cash return of around 1.8%, before any capital growth. Same property, very different picture, depending on which question you ask.

2. Total Return Over a Holding Period

This combines net rental income with capital growth over time, typically viewed across five years for off-plan property, given completion timelines and the time a development needs to bed in. A property with a modest yield but strong capital growth can comfortably outperform a higher-yielding property in a stagnant area once you look at total return rather than income alone. Our guide on how to build a property portfolio shows how total return drives long-term growth.

Wider market data backs this up. Analysis of the UK rental market shows a clear split between locations that offer strong yield and those that offer strong capital growth, with few offering both equally. Our guide to the best places to invest in property in the UK looks at where different locations sit on that spectrum, and our comparison of off-plan property vs buying on the open market covers how capital growth factors into the investment case.

Putting It Together: A Total Return Illustration

Here’s why total return changes the picture. Take the same one-bed apartment, bought for £188,000 with a £47,000 deposit and let on a standard tenancy.

The rental income covers the costs of owning the property; the capital growth, amplified by the mortgage, does most of the heavy lifting. That’s why a low net yield on a well-located, mortgaged property isn’t a red flag in itself, provided the property is in a location with genuine growth drivers behind it.

This is an illustration, not a forecast. It assumes 4% annual growth, which is not guaranteed, and excludes buying and selling costs and tax. Property values can fall as well as rise.

Why So Few Providers Show the Full Costs

Management fees, service charges and mortgage costs aren’t hidden information, but they’re routinely left out of headline figures because the resulting number is less impressive. A development marketed on a clean 8% gross yield is a stronger sales line than one presented with a realistic 1% net figure, even though the second number is the one that actually matters to your bank balance.

To be transparent, we quote gross yield in our own marketing too. It’s standard practice across the industry, and it allows a fair, like-for-like comparison between developments before the costs specific to each one are applied. The issue isn’t using gross yield; it’s stopping there. Gross yield as a headline is reasonable. Gross yield as the only figure you’re ever shown is not.

This is where due diligence matters as much as the numbers themselves. Asking whether a quoted yield is gross or net is a reasonable and necessary question, not an awkward one. It’s also worth understanding how tax applies to rental income, since the rules on mortgage interest relief have changed significantly. HMRC’s guidance on paying tax when renting out a property is the definitive source, and our guide to buying property through a limited company explains how finance costs are treated differently inside a company.

How We Handle This on a Discovery Call

At Providence Wealth, every discovery call includes a full run-through of the actual figures for a specific unit, not a generic brochure percentage: gross yield, net yield after realistic costs, cash-on-cash return based on your actual deposit, and a year-by-year projection of total return over five years.

That transparency is only half of what we do. The other half is making sure the numbers stack up before a development ever reaches you:

• Every development is vetted through our due diligence process: the developer’s track record, the location’s growth drivers, rental demand, and the realistic numbers, not the brochure ones.
• We focus on locations with strong rental demand and regeneration behind them, which is what drives both rental income and capital growth over time. You can see our current selection on our investment properties page.
• Many of our developments have short let approval, giving you the flexibility to choose the rental strategy that delivers the best return.
• We make the whole process hands-off: introductions to whole of market mortgage brokers, solicitors and property managers, plus limited company setup at no extra cost where it suits you.
• We invest in the same developments we recommend. If we wouldn’t back it ourselves, we won’t bring it to you.

Very few providers in this space run this level of detail live on a call. Our view is simple: if you’re being asked to reserve a property, you should know exactly where you stand financially before you do, and feel confident about why the numbers work.

Gross Yield vs Net Yield: Frequently Asked Questions

What is the difference between gross yield vs net yield?

Gross yield is annual rent divided by purchase price, with no costs deducted. Net yield deducts the running costs of owning and letting the property (management fees, service charges, insurance, maintenance and, depending on the definition, mortgage interest) before dividing by the purchase price.

How do you calculate rental yield?

For gross yield, divide the annual rent by the purchase price and multiply by 100. For net yield, subtract your annual running costs from the annual rent first, then divide by the purchase price and multiply by 100.

What is a good rental yield in the UK?

It varies considerably by region and property type. According to UK Finance, the average gross buy-to-let rental yield across the UK was 7.27% in Q2 2026. Net yield, after costs and any financing, is typically several percentage points lower.

Does net yield include mortgage payments?

It depends on whose definition you’re using, as there’s no universally agreed standard. Some calculations include mortgage interest as a cost; others treat net yield as a pre-financing figure. This article includes mortgage interest throughout, as it’s a genuine cash cost for most buy-to-let investors.

What is cash-on-cash return, and how is it different from yield?

Cash-on-cash return measures your net income against the cash you’ve actually invested (your deposit and associated costs), rather than the full purchase price. For a mortgaged purchase, it’s usually more meaningful than either gross or net yield.

Should I compare properties on gross yield or net yield?

Gross yield is useful for a quick, like-for-like comparison, because it strips out variables like financing and management costs that differ between buyers. Net yield, cash-on-cash return and total return are what decide whether an investment makes sense for you, and should be reviewed before you reserve.

The Bottom Line

Gross yield is useful for comparing properties quickly. Net yield tells you what the investment is actually producing. Cash-on-cash return tells you how efficiently your money is working. Total return tells you whether the investment is genuinely worth making. Good investors understand all four, not just the one printed on the brochure.
