Rental Yield Calculator UK 2026

What is rental yield?

Rental yield is the annual rental income from a property expressed as a percentage of the property's value. It is the primary measure of income return for buy-to-let investors.

Think of rental yield as the interest rate on your property investment. Just as a savings account might pay 4% on your deposit, a rental property might yield 5% or 6% on the capital tied up in it. The difference is that property also offers potential capital growth, the chance that the property itself increases in value over time.

Yield is distinct from total return. Total return includes both rental income and capital appreciation, while yield focuses purely on the income side. A property in London might yield only 3.5% but grow in value by 5% per year, giving a total return of 8.5%. A property in Sunderland might yield 8% but experience minimal capital growth. Both can be sound investments depending on your strategy.

There are two types of rental yield that matter: gross yield and net yield. Understanding the difference between them is critical to making accurate investment decisions.

Gross yield vs net yield: what is the difference?

Gross yield uses the full rental income with no deductions. Net yield subtracts all annual running costs before calculating the percentage. Net yield is the more useful figure for comparing investment performance.

Gross rental yield

Gross yield is the simplest calculation. It takes the annual rental income and divides it by the property value:

Gross yield = (annual rent / property value) x 100

For example, a property worth £200,000 that achieves £1,000 per month in rent produces £12,000 per year in income. The gross yield is (£12,000 / £200,000) x 100 = 6.0%.

Gross yield is useful for quick comparisons between properties and is the figure most commonly quoted in property listings and market reports. However, it paints an incomplete picture because it ignores all the costs associated with owning and managing the property.

Net rental yield

Net yield accounts for the real costs of ownership. It deducts annual expenses from the rental income before dividing by the property value:

Net yield = ((annual rent - annual costs) / property value) x 100

Using the same example: £200,000 property, £12,000 annual rent, but with £4,500 in annual costs (insurance, maintenance, management fees, void periods). Net yield = ((£12,000 - £4,500) / £200,000) x 100 = 3.75%.

That gross yield of 6% drops to a net yield of 3.75% once real costs are factored in. The gap between gross and net is typically 1.5% to 3%, depending on property type, location, and management approach. Self-managing landlords who handle repairs and tenant-finding themselves will have a smaller gap than those using a full-service letting agent at 10-12% of rent.

Which costs to include in net yield

To calculate an accurate net yield, include these annual costs:

• Mortgage interest (not capital repayments, which build equity)
• Buildings and landlord insurance
• Letting agent or management fees (typically 8-12% of rent for tenant-find and management)
• Maintenance and repairs (budget 5-10% of annual rent)
• Ground rent and service charges (for leasehold properties)
• Void periods (typically 4-8% of annual rent, or one month empty per year)
• Accountancy fees
• Landlord licensing costs (where applicable)
• Safety certificates (gas, electrical, EPC renewals)

Do not include mortgage capital repayments. Capital repayments reduce your outstanding loan and build your equity in the property. They are a form of saving, not an expense. However, you should include capital repayments in your cash flow calculations, because they affect the actual money going in and out of your bank account each month.

What is a good rental yield in the UK?

A gross yield above 6% is generally considered good. Between 4% and 6% is average. Below 4% is low and typically only justified if the property has strong capital growth prospects.

These are guidelines rather than fixed rules. A 4% yield in a prime London borough with strong capital growth and minimal void risk may be a better long-term investment than an 8% yield in a deprived area with high tenant turnover and maintenance costs. Context matters.

For net yield, aim for at least 3.5% to 4% after all costs. If your net yield is below 2%, the property is arguably not working hard enough as a pure income investment, unless capital appreciation makes up the difference.

The threshold also depends on your financing. A cash buyer needs a lower yield to cover costs than a landlord with a 75% loan-to-value mortgage. Mortgage interest is typically the single largest cost, and it has a substantial impact on net yield.

Average rental yields by UK region

Yields vary significantly across the UK. Northern England and Scotland consistently deliver the highest gross yields, while London and the South East have the lowest.

These figures are averages and vary considerably at local level. A two-bedroom terraced house in a student area of Manchester will yield very differently from a new-build apartment in Salford Quays. Always calculate yield on the specific property and comparable rents, not regional averages.

The general pattern is straightforward: lower property prices relative to rents produce higher yields. Northern cities have lower property values but rents have not fallen proportionally, creating a wider yield spread. London has the highest rents in absolute terms, but property values are so elevated that the percentage return is relatively low.

How to calculate rental yield: step-by-step examples

Calculating rental yield takes three numbers: the property value, the annual rent, and (for net yield) the annual running costs. Here are worked examples at different price points.

Example 1: Terraced house in Manchester, £180,000

Property value: £180,000. Monthly rent: £850. Annual rent: £10,200.

Gross yield = (£10,200 / £180,000) x 100 = 5.67%

Annual costs: mortgage interest £4,320, insurance £280, maintenance £800, void (one month) £850, gas/electrical certificates £180. Total annual costs: £6,430.

Net yield = ((£10,200 - £6,430) / £180,000) x 100 = 2.09%

Monthly cash flow = (£10,200 - £6,430) / 12 = £314/month

Example 2: Two-bed flat in Leeds, £140,000

Property value: £140,000. Monthly rent: £750. Annual rent: £9,000.

Gross yield = (£9,000 / £140,000) x 100 = 6.43%

Annual costs: mortgage interest £3,360, insurance £250, service charge £1,200, maintenance £600, void £750, certificates £180. Total annual costs: £6,340.

Net yield = ((£9,000 - £6,340) / £140,000) x 100 = 1.90%

Monthly cash flow = (£9,000 - £6,340) / 12 = £222/month

Example 3: Semi-detached in Birmingham, £250,000

Property value: £250,000. Monthly rent: £1,100. Annual rent: £13,200.

Gross yield = (£13,200 / £250,000) x 100 = 5.28%

Annual costs: mortgage interest £6,000, insurance £320, management fees (10%) £1,320, maintenance £1,000, void £1,100, certificates £200. Total: £9,940.

Net yield = ((£13,200 - £9,940) / £250,000) x 100 = 1.30%

Monthly cash flow = (£13,200 - £9,940) / 12 = £272/month

Example 4: One-bed flat in London, £400,000

Property value: £400,000. Monthly rent: £1,500. Annual rent: £18,000.

Gross yield = (£18,000 / £400,000) x 100 = 4.50%

Annual costs: mortgage interest £9,600, insurance £400, service charge £2,400, management fees (10%) £1,800, maintenance £1,200, void £1,500, certificates £200. Total: £17,100.

Net yield = ((£18,000 - £17,100) / £400,000) x 100 = 0.23%

Monthly cash flow = (£18,000 - £17,100) / 12 = £75/month

This London example illustrates why many London landlords rely on capital growth rather than income. The property may appreciate by £20,000 or more per year, dwarfing the thin rental profit, but the cash flow is marginal.

Yield scenarios compared

This table compares the same £250,000 investment across different rental and cost assumptions to show how sensitive yield is to small changes.

Small differences compound over time. A £150 per month difference in rent on a £250,000 property changes the gross yield by nearly 0.75 percentage points and can mean the difference between a comfortable cash flow and a property that barely breaks even.

Purchase price vs current value: which should you use?

Use purchase price (yield on cost) to measure the return on your original investment. Use current market value to decide whether the capital currently locked in the property is working hard enough.

These are two different questions:

• Yield on cost (purchase price): "Am I getting a good return on what I paid?" This figure only gets better over time if rents rise, because the purchase price is fixed.
• Yield on value (current market value): "Is this property the best use of the capital I have tied up in it?" If your property has doubled in value, the yield on value will be roughly half the yield on cost. This helps you decide whether to hold, remortgage to release equity, or sell and reinvest.

For example, you bought a property in 2015 for £150,000 and it is now worth £250,000. Rent is £1,000 per month (£12,000 per year).

• Yield on cost: (£12,000 / £150,000) x 100 = 8.0%
• Yield on value: (£12,000 / £250,000) x 100 = 4.8%

The 8% yield on cost looks excellent. But the 4.8% yield on value reveals that the £250,000 of equity locked in this property is only generating a 4.8% income return. Could that £250,000 work harder elsewhere? That is the question yield on value helps you answer.

Rental yield vs capital growth

Yield and capital growth often move in opposite directions. High-yield areas tend to have lower property price growth, and high-growth areas typically have lower yields. The best strategy depends on your investment goals.

This is one of the most important tensions in property investing. Northern cities with yields of 7-9% have historically seen lower capital appreciation than London and the South East. London properties yielding 3-4% have often grown in value by 5-7% per year over the long term.

Neither strategy is inherently better. Income-focused investors want properties that pay for themselves from day one and generate surplus cash flow. Growth-focused investors accept thinner yields in exchange for building wealth through property price appreciation. Many experienced landlords hold a mix, with high-yield properties funding the portfolio and growth properties building long-term wealth.

Total return matters more than either metric in isolation. A 4% yield plus 5% capital growth gives a 9% total return, which is a strong result by any measure. A 7% yield with 1% growth gives an 8% total return, which is also good but with a very different risk and cash flow profile.

How to improve your rental yield

Yield can be improved either by increasing rent or by reducing costs. Here are the most effective strategies for both.

Increase rental income

• Refurbish and modernise. Updating kitchens, bathrooms, and flooring can justify a significant rent increase. A £5,000 kitchen refurbishment on a £200,000 property that enables a £100/month rent increase improves gross yield by 0.6% and pays for itself in just over four years.
• Add a bedroom. Converting a reception room or loft into an additional bedroom can increase rent by 15-25%. Check planning requirements and building regulations.
• Furnish the property. Furnished properties typically command 10-15% higher rent than unfurnished equivalents, though you take on the cost and wear of furniture.
• Target professional tenants. Properties marketed to professionals or couples often achieve higher rents than those aimed at benefit-dependent tenants, with lower void rates and less wear.
• Review rent annually. Many landlords leave rents unchanged for years. If market rents have risen, use a Section 13 notice to bring rent in line. Even modest increases of £25-50 per month compound significantly over time.
• Consider HMO conversion. House in Multiple Occupation lets to individual room tenants rather than a single household. A four-bedroom house renting as a whole for £1,200/month might achieve £2,000/month as an HMO with four rooms at £500 each. HMOs require additional licensing and regulation.

Reduce costs

• Self-manage. Letting agent fees of 10-12% of rent are one of the biggest costs. Self-managing removes this entirely. Tools like LandlordOS make self-management significantly easier by automating compliance tracking, financial recording, and tenant communication.
• Shop around for insurance. Landlord insurance prices vary enormously. Use a specialist broker and review annually. Savings of £100-200 per year are common.
• Preventative maintenance. Regular property inspections and servicing catch small problems before they become expensive repairs. A £150 annual boiler service prevents £2,000 emergency breakdowns.
• Remortgage for a better rate. Mortgage interest is typically the largest single cost. Even a 0.25% reduction on a £150,000 mortgage saves £375 per year. Review your mortgage at every product expiry.
• Reduce voids. Every month without a tenant costs you the full monthly rent plus ongoing bills. Start marketing the property before the current tenant leaves. Build good relationships with tenants so they stay longer.
• Claim all allowable expenses. Many landlords miss legitimate tax deductions. Every expense you claim reduces your tax bill, effectively improving your after-tax yield.

The impact of mortgage leverage on yield

Mortgage leverage amplifies both returns and risk. A landlord who buys with a 75% mortgage earns a much higher return on their deposited cash than the property's headline yield suggests.

This is the key distinction between rental yield and return on investment (ROI). Yield is calculated on the full property value. ROI is calculated on the cash you actually put in.

Consider a £200,000 property with a 25% deposit (£50,000) and a 75% interest-only mortgage at 4.5% (£6,750 per year in interest). Monthly rent is £1,000 (£12,000 per year). Other annual costs: £3,000.

• Gross yield: (£12,000 / £200,000) x 100 = 6.0%
• Net yield: ((£12,000 - £9,750) / £200,000) x 100 = 1.13%
• Annual profit: £12,000 - £9,750 = £2,250
• Return on cash invested: (£2,250 / £50,000) x 100 = 4.5%

The net yield of 1.13% looks thin, but the ROI on your £50,000 cash is 4.5%, not including any capital growth. If the property grows by 3% per year (£6,000), your total return on the £50,000 invested is (£2,250 + £6,000) / £50,000 = 16.5%. Leverage turns a modest yield into a strong return.

The flip side: leverage also amplifies losses. If the property falls in value, your percentage loss on deposited cash is magnified. And if rents drop or void periods extend, the mortgage payment is still due. Higher leverage means higher risk.

Rental yield and stamp duty

Stamp duty is a one-off purchase cost, but it directly affects your yield calculations and payback period. The 5% buy-to-let surcharge makes this particularly significant for investment property.

When calculating yield, you can either use the property price alone (the standard approach) or include stamp duty and other purchase costs in your total investment figure. The second approach gives a more realistic picture of the return on total money deployed.

On a £250,000 buy-to-let purchase, stamp duty with the 5% surcharge is £12,500. Legal fees, surveys, and other costs might add another £3,000. Total investment is £265,500.

• Yield on property value: (£13,200 / £250,000) x 100 = 5.28%
• Yield on total cost: (£13,200 / £265,500) x 100 = 4.97%

The difference is small but meaningful over time. Use the stamp duty calculator to check the exact SDLT cost before running your yield numbers.

Rental yield and tax

Income tax on rental profits reduces your effective after-tax yield. The impact depends on your marginal tax rate and how you structure your ownership.

Rental income is added to your other income for tax purposes. If your total income puts you in the 40% tax bracket, your rental profits are taxed at 40%. A property generating £5,000 net profit per year would leave you with £3,000 after tax, a very different proposition.

Section 24 mortgage interest restrictions (fully phased in since April 2020) mean individual landlords can no longer deduct mortgage interest as an expense. Instead, they receive a 20% tax credit on interest paid. Higher-rate taxpayers are particularly affected, effectively paying tax on income that is consumed by mortgage interest.

Some landlords use a limited company structure to mitigate Section 24. Companies can fully deduct mortgage interest and pay Corporation Tax at 25% rather than income tax at up to 45%. However, extracting profits from the company as dividends creates an additional tax layer. The decision depends on your personal circumstances, portfolio size, and mortgage requirements.

For a full analysis, see the Section 24 mortgage interest guide.

From April 2026, landlords with rental income above £50,000 must comply with Making Tax Digital (MTD), submitting quarterly digital updates to HMRC. This applies to the 2026/27 tax year onwards. LandlordOS is designed to make MTD compliance straightforward, with automatic categorisation and quarterly reporting built in.

Common mistakes when calculating rental yield

The most common mistakes are using asking rent instead of achievable rent, ignoring void periods, and not accounting for the full range of operating costs.

1. Using asking rent, not achievable rent

Property listings show asking rent, which is often 5-10% higher than the rent actually achieved after negotiation. Always base your calculations on comparable achieved rents for similar properties in the same area, not the agent's optimistic listing price.

2. Ignoring void periods

Many landlords calculate yield assuming 12 months of rent per year. In practice, most properties experience some void. A one-month void reduces your annual income by 8.3%. Budget for at least one month per year, or 4-8% of annual rent.

3. Underestimating maintenance costs

New landlords often budget £500 per year for maintenance and are surprised when a boiler replacement costs £3,000 or a bathroom refurbishment costs £4,000. Budget 10% of annual rent for maintenance, and keep a reserve fund for major works.

4. Forgetting about Section 24

Many yield calculators (including the gross yield formula) do not account for the tax impact of Section 24 mortgage interest restrictions. A property that looks profitable on a pre-tax basis can generate a tax bill that exceeds the actual cash profit, particularly for higher-rate taxpayers.

5. Comparing gross yields when costs differ

Comparing gross yields between a freehold house and a leasehold flat is misleading. The flat might have £2,000 per year in service charges and ground rent that the house does not. Always compare net yields when evaluating different property types.

6. Using outdated property valuations

Calculating yield on a property you bought five years ago using the original purchase price gives a flattering but misleading picture. For ongoing portfolio management, use current market values to assess whether each property is pulling its weight.

7. Not accounting for management costs when self-managing

Self-managing landlords sometimes calculate yield without any management cost, treating their own time as free. While this is technically correct for yield purposes, it is worth considering the value of your time. If self-management takes 5 hours per month and you value your time at £50/hour, that is £3,000 per year in opportunity cost.

Yield by property type

Different property types produce different yield profiles. HMOs typically yield the highest, followed by smaller units. Larger family homes and new-builds tend to yield less.

The best yielding properties tend to be small to mid-size homes in areas with strong tenant demand and relatively low property values. Two-bedroom terraced houses in northern cities are the classic high-yield investment. At the other end, luxury properties and large detached homes rarely yield well as rentals because the property value is disproportionate to the rent achievable.

How LandlordOS calculates your actual yield

LandlordOS tracks real income and expenditure for each property, giving you an accurate, up-to-date net yield figure based on actual data rather than estimates.

The calculator on this page is useful for evaluating potential purchases, but once you own a property, estimated costs should be replaced with real numbers. LandlordOS does this automatically:

• Income tracking: Every rent payment is recorded against the specific property, including partial payments and void periods.
• Expense tracking: Upload bank statements and receipts. AI categorisation assigns each expense to the correct property and cost category.
• Per-property P&L: See profit and loss for each property individually, with gross yield, net yield, and monthly cash flow calculated from actual data.
• Portfolio overview: Aggregate view across all properties, showing which are performing and which need attention.
• Tax reporting: All income and expenses feed directly into quarterly MTD submissions and your annual Self Assessment.

Knowing your actual yield, not an estimate, is the difference between thinking your properties are profitable and knowing they are. Sign up for free and connect your first property in minutes.

Rental yield and the Renters' Rights Act 2025

The Renters' Rights Act 2025, which abolishes Section 21 from 1 May 2026, does not directly change rental yields. However, the shift to periodic tenancies and stronger tenant protections may affect void periods and management costs.

Key changes that could impact yield calculations:

• No more Section 21 "no-fault" evictions. Removing tenants who are not in breach of their tenancy becomes harder. This increases the importance of thorough tenant referencing upfront.
• Periodic tenancies by default. Fixed-term ASTs will no longer exist. Tenants can give two months' notice at any time. This could increase turnover and void costs for some landlords.
• Rent increases limited to once per year via the Section 13 process. Landlords cannot build in rent review clauses or increase rent more than once every 12 months.
• Decent Homes Standard. Rental properties will need to meet a minimum standard, potentially requiring investment to bring older properties up to standard.

For most well-run properties with good tenants, the impact on yield should be minimal. Landlords who rely on frequent tenant turnover, below-standard properties, or above-market rent increases may see their yields compressed.
