Rental Yield Calculator
Calculate gross and net rental yield on an investment property using annual rental income, property value, and operating expenses.
Calculator
Formula
Gross Yield is the annual rental income divided by the property purchase price, expressed as a percentage. Net Yield refines this by subtracting all annual operating expenses (management fees, insurance, maintenance, void periods, etc.) from the annual rent before dividing by the property value.

How it works
Gross rental yield is the simplest measure of a property's income performance. It is calculated by dividing the total annual rental income by the property's purchase price (or current market value) and multiplying by 100 to express it as a percentage. For example, a property worth £250,000 that generates £14,400 per year in rent produces a gross yield of 5.76%. Gross yield gives a quick, comparable snapshot but ignores the real costs of ownership.
Net rental yield is the more meaningful metric for serious investors because it accounts for all annual operating costs. These costs typically include letting agent management fees (usually 8–15% of rent), landlord insurance, routine maintenance and repairs, ground rent and service charges (for leasehold properties), accountancy fees, safety certification costs, and an allowance for void periods when the property sits empty. Subtracting these from annual rent before dividing by the property value yields a far more realistic picture of true investment return.
Most experienced property investors target a gross yield of at least 5–6% in the UK, with net yields of 3.5–5% considered acceptable depending on location and growth prospects. High-yield areas (often in northern England) may produce gross yields of 7–10%, while prime London locations sometimes yield just 2–3% gross — with investors in such cases typically banking on capital appreciation rather than income. Comparing net yield across multiple properties on an equal-expenses basis is the most rigorous way to shortlist investment candidates.
Worked example
Consider a buy-to-let flat purchased for £200,000. The landlord charges £950 per month in rent, generating an annual rental income of £11,400.
Step 1 — Gross Yield: Divide annual rent by property value: £11,400 ÷ £200,000 = 0.057. Multiply by 100 to get 5.70% gross yield.
Step 2 — Calculate Annual Expenses: The landlord pays a letting agent 10% of rent (£1,140), landlord insurance (£300), annual gas safety certificate and electrical inspection (£200), an allowance for maintenance (£500), and accounts for one month's void per year (£950). Total annual expenses = £3,090.
Step 3 — Net Yield: Subtract expenses from annual rent: £11,400 − £3,090 = £8,310 net annual income. Divide by property value: £8,310 ÷ £200,000 = 0.04155. Multiply by 100 to get 4.16% net yield.
This means the investor earns a net cash return of 4.16% on their £200,000 asset — a reasonable return compared to savings rates, though the investor would also need to factor in mortgage financing costs if the property was purchased with a buy-to-let mortgage.
Limitations & notes
This calculator computes yield based on pre-tax income and does not account for mortgage interest payments, stamp duty land tax (SDLT), or income tax on rental profits — all of which can materially reduce the actual return received by a leveraged investor. The net yield output is only as accurate as the expenses entered; many landlords underestimate costs, particularly maintenance and void periods. Yield also ignores capital growth, which is often a primary driver of total return in low-yield, high-demand markets. For a complete investment appraisal, net yield should be used alongside metrics such as Return on Equity (ROE), cash-on-cash return, and projected total return including appreciation. Property values and rents fluctuate over time, so yields calculated at purchase may differ significantly from yields realised over a multi-year holding period.
Frequently asked questions
What is a good rental yield in the UK?
A gross rental yield of 5–6% is generally considered the minimum threshold for a viable buy-to-let investment in the UK, with 7% or above regarded as strong. Net yields of 3.5–5% are typical after expenses, though what counts as 'good' depends heavily on local market conditions, your financing costs, and whether you are prioritising income or capital growth. Locations such as Liverpool, Hull, and Middlesbrough regularly produce gross yields above 7%, while central London boroughs may yield as little as 2–3%.
What is the difference between gross and net rental yield?
Gross rental yield is calculated using total annual rent divided by property value, without deducting any costs — it gives a quick comparison figure but overstates actual returns. Net rental yield deducts all annual operating expenses (management fees, insurance, maintenance, void periods, certificates, etc.) from the annual rent before dividing by property value, giving a far more realistic measure of the income you actually receive. Serious investors should always base decisions on net yield, using gross yield only for initial shortlisting.
Should I use purchase price or current market value to calculate yield?
Using the original purchase price shows your return on the capital you deployed and is most relevant when evaluating a prospective acquisition. Using the current market value shows your yield on today's asset worth — useful for benchmarking whether the property still represents good value relative to alternatives or whether you could redeploy that capital more productively elsewhere. Many investors calculate both: yield on cost to evaluate original investment quality, and yield on value to inform ongoing hold-or-sell decisions.
Does rental yield include mortgage costs?
Standard rental yield calculations do not include mortgage repayments, because yield is intended to measure the income-generating performance of the asset itself, independent of how it is financed. If you want to assess the actual cash return on your equity (deposit plus any additional capital invested), you should calculate the cash-on-cash return, which deducts mortgage interest from net income and divides by the total cash invested. For leveraged investors, this is a more meaningful profitability metric than yield alone.
What expenses should I include in the net yield calculation?
The most common annual expenses to include are: letting agent management fees (typically 8–15% of annual rent if fully managed), landlord building and contents insurance, routine maintenance and repairs (a common rule of thumb is 1% of property value per year), gas safety certificates and electrical installation condition reports (EICRs), service charges and ground rent for leasehold properties, accountancy fees, and an allowance for void periods (at least one month's lost rent per year is prudent). Mortgage interest, income tax, and one-off capital expenditures such as refurbishments are often excluded from the running yield calculation but must be factored into overall investment appraisal.
