Rental Yield Calculator: How to Measure Your Property's Income Performance

What Is Rental Yield?

Rental yield expresses annual rent as a percentage of property value. The calculation has two forms.

Gross rental yield ignores running costs:

Gross Yield (%) = (Annual Rent / Property Value) x 100

Net rental yield subtracts annual costs from the rent figure before dividing:

Net Yield (%) = ((Annual Rent - Annual Costs) / Property Value) x 100

Annual costs typically include property management fees, insurance, maintenance reserves, landlord insurance, void periods, and any service charges or ground rent. Mortgage interest is sometimes excluded because it varies by financing structure, but including it gives the most realistic picture of cash-flow yield.

How to Use This Calculator

1. Enter the property value. Use the current market value if you already own the property, or the purchase price (including purchase costs) if you are evaluating a prospective buy.
2. Enter the annual rent. If your rent is monthly, multiply by 12. If you expect seasonal voids, reduce the figure proportionally. For example, one month void per year means you enter 11 months of rent.
3. Enter annual costs (optional). Input total annual running costs to get the net yield figure. Leave this field blank if you only need gross yield.
4. Read the result. The tool returns gross yield, net yield (if costs were entered), and the monthly rent figure for reference.

How to Interpret Rental Yield Results

Yield benchmarks vary by market, property type, and investment strategy. These ranges are general guides, not guarantees.

A high yield does not automatically mean a good investment. Properties with yields above 8 to 10% sometimes carry elevated vacancy risk, higher maintenance costs, or are located in declining markets. Yield must be read alongside capital growth prospects, void rate history, and local demand fundamentals.

When to Use the Rental Yield Calculator

Before making a purchase. Compare yield across several properties or postcodes to filter the most efficient candidates. A property priced at a 3% gross yield in a low-growth area is very different from one at 3% in a market with consistent 6 to 8% annual capital appreciation.

When reviewing an existing portfolio. Yields drift as rents rise or fall relative to property values. Recalculating annually tells you whether a property is still earning its place in the portfolio or whether rent is due for review.

When considering refinancing. Lenders and mortgage assessors often require rental coverage ratios (rent must cover a multiple of the mortgage payment). Knowing your yield helps you model how different loan-to-value ratios affect serviceability. Pair this with our mortgage amortization calculator to stress-test repayment scenarios.

When comparing property to other asset classes. A 5.5% net yield from a rental property can be compared directly with dividend yields from equities or interest rates on bonds. This comparison only holds if the yield figure is realistic, which requires netting out costs.

Example Calculation: Terraced House

A two-bedroom terraced house in a regional city:

• Purchase price: £185,000
• Annual rent: £11,400 (£950/month)
• Annual costs: £2,800 (management 10%, insurance, maintenance reserve)

Gross yield = (11,400 / 185,000) x 100 = 6.16%

Net yield = ((11,400 - 2,800) / 185,000) x 100 = 4.65%

The gap between gross and net here is 1.5 percentage points. That gap widens for higher-cost properties (such as those with service charges or requiring regular maintenance) and narrows for low-overhead properties managed directly by the owner.

Example Calculation: HMO Property

A five-bed house in multiple occupation:

• Purchase price: £320,000
• Annual rent: £32,400 (five rooms at £540/month each)
• Annual costs: £9,500 (management, licensing fees, utilities landlord-paid, higher maintenance)

Gross yield = (32,400 / 320,000) x 100 = 10.13%

Net yield = ((32,400 - 9,500) / 320,000) x 100 = 7.16%

High-yield HMO properties often have significantly higher cost ratios. In this example, costs consume roughly 29% of income. A landlord who only looks at gross yield would overestimate the actual return by nearly 3 percentage points.

Rental Yield vs. Cap Rate

Investors comparing property across markets or working with commercial property will encounter the cap rate (capitalisation rate). Cap rate is calculated similarly to net yield but is always expressed on a net operating income basis, before financing costs and tax. For residential property, net rental yield and cap rate are often used interchangeably, but the definitions differ in commercial and mixed-use contexts. If you are evaluating commercial property or comparing UK residential yield to US investment metrics, ensure the cost deductions in each calculation are consistent before drawing conclusions. See our cap rate calculator for a side-by-side view.

Notes on Accuracy

This calculator performs the standard gross and net yield calculations used across the property investment industry. It does not account for tax treatment, which varies by ownership structure (individual landlord, limited company, REIT). It also does not model financing costs unless you choose to include mortgage interest in your annual costs figure. For a full investment appraisal, pair rental yield with vacancy rate assumptions, capital growth projections, and a full cashflow model across your intended holding period.
