Rental Yield Calculator: How to Measure Your Property's Income Performance
Rental yield is one of the most direct measures of how well an investment property performs. It tells you, as a percentage, how much annual rent income you earn relative to the property's value. Before committing to a purchase, extending a portfolio, or reviewing existing holdings, calculating rental yield gives you a clear, comparable number to work with. This calculator handles both gross yield and net yield. Enter your property value, annual rental income, and optional costs, and the tool returns the figures instantly.

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.
When should you use the Rental Yield Calculator: How to Measure Your Property's Income?
Use this calculator when screening rental properties to quickly compare income potential across different properties and markets. Gross yield helps you filter properties in early research stages: anything below 5-6% gross yield is unlikely to cash flow. Net yield helps you make final purchase decisions because it accounts for the real cost of owning and operating the property. The tool is especially useful when comparing properties in different cities with different tax rates and operating costs, or when evaluating whether a property justifies the asking price based on the income it produces.
How do you read the Rental Yield Calculator: How to Measure Your Property's Income results?
Gross yield typically ranges from 5-10% depending on the market and property type. Anything below 5% suggests the property is priced for appreciation, not income. Net yield is typically 2-5 percentage points lower than gross yield due to operating expenses. A property with 8% gross yield and 5% net yield is spending 3% of value on annual operating costs. If net yield is below 4%, the property will likely not cash flow unless you have a large down payment. Compare net yield to your mortgage rate: if net yield is below your interest rate, leverage works against you and the property loses money unless it appreciates.
How to Use This Calculator
- 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.
- 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.
- 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.
- 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.
| Yield Range | Interpretation |
|---|---|
| Below 3% | Low yield. Common in prime urban or high-capital-growth markets. Cash flow is tight. |
| 3% to 5% | Average yield. Typical for most established residential markets. |
| 5% to 7% | Good yield. Strong cash flow. Common in secondary cities and high-demand rental areas. |
| Above 7% | High yield. May indicate higher risk, lower capital growth potential, or specialist property types (HMOs, student lets, short-term rentals). |
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.
Frequently asked questions
What is the difference between rental yield and cap rate?
Rental yield and cap rate are nearly identical when calculated correctly. Both measure unleveraged return as a percentage of property value. The difference is terminology: yield is more common in UK and Australian markets, while cap rate is standard in U.S. commercial real estate. Net rental yield equals cap rate when both use the same definition of operating expenses. Gross rental yield is less useful because it ignores operating costs. Use whichever term is standard in your market, but always calculate net yield (or cap rate) for accurate comparisons.
What is a good rental yield for a residential property?
A good gross rental yield for residential properties ranges from 6-10%, with net yield typically 2-5 percentage points lower. In expensive coastal markets (SF, NYC, LA), gross yields of 4-6% are common because property values are high relative to rents, but investors buy for appreciation. In affordable Midwest or Sun Belt markets, gross yields of 8-12% are common because property values are low relative to rents. Target net yields above 5% if you want positive cash flow after financing at typical mortgage rates.
How much should I budget for operating expenses as a percentage of rent?
Operating expenses typically consume 30-50% of gross rental income on single-family and small multifamily properties. Property tax and insurance alone can take 15-25%, depending on the state. Maintenance, repairs, and vacancy allowances add another 10-20%. If you budget 40% of gross rent for operating expenses, you are in the safe range for most properties. Newer properties with low maintenance needs may run at 30%, while older properties or those in high-tax states can exceed 50%. Track actual expenses for the first year to refine your estimates.
Should I use gross yield or net yield to compare properties?
Always use net yield for final comparisons because it accounts for the real cost of ownership. Gross yield is useful for quick screening (anything below 6% gross is unlikely to cash flow), but it overstates returns by ignoring expenses. Two properties with the same gross yield can have very different net yields if one has high property taxes or deferred maintenance. Net yield gives you an apples-to-apples comparison of actual income potential. The OnSumo cap rate calculator can help you calculate net yield accurately.
What is the relationship between rental yield and property appreciation?
High-yield properties (8-12% gross) typically offer strong cash flow but limited appreciation. They are often in secondary or tertiary markets with slow population or income growth. Low-yield properties (3-5% gross) typically offer weak cash flow but strong appreciation potential. They are often in high-growth markets where rents and values rise faster than national averages. Investors targeting income prioritize yield. Investors targeting wealth accumulation prioritize appreciation. Most investors want both, which usually means 6-8% gross yield in markets with moderate growth.
How does rental yield affect my ability to cash flow with a mortgage?
If your net rental yield is below your mortgage interest rate, the property will lose money unless you make a large down payment. For example, if net yield is 5% and your mortgage rate is 6%, the property generates $5 per $100 of value but costs $6 per $100 borrowed. You can only cash flow if you put enough down to reduce the loan balance and monthly payment. The OnSumo cash-on-cash return calculator can help you model different down payment scenarios to find the break-even point.
Can rental yield change over time?
Yes, rental yield changes as property values and rents change. If property values rise faster than rents, yield compresses (falls). If rents rise faster than property values, yield expands (rises). For example, if you buy at $200,000 with $18,000 annual rent (9% gross yield), and the property appreciates to $250,000 while rent stays flat, your yield drops to 7.2% ($18,000 / $250,000). If you sell, the new buyer also gets 7.2% yield at the higher price. Track yield over time to decide when to sell and reallocate capital to higher-yielding opportunities.
What is a yield-on-cost and how is it different from rental yield?
Yield-on-cost measures rental income as a percentage of your original purchase price, while rental yield measures income as a percentage of current market value. If you bought for $200,000 and the property is now worth $300,000, your yield-on-cost is higher than current market yield. For example, $18,000 rent gives 9% yield-on-cost ($18,000 / $200,000) but only 6% market yield ($18,000 / $300,000). Yield-on-cost shows your actual return as the original buyer. Market yield shows what a new buyer would earn today.
How do I estimate rental income for a property I am considering buying?
Research comparable rental properties in the same neighborhood with similar bed/bath counts, square footage, and condition. Use Zillow, Rentometer, or local property management companies to find recent rental comps. Call a few property managers and ask what the property would rent for; they have the most accurate data. Assume a 5-10% vacancy allowance (even if you plan to keep it rented 100% of the time) to account for turnover. If the seller claims above-market rent, verify with comps before using it in your yield calculation.
What is the 1% rule and how does it relate to rental yield?
The 1% rule is a quick screening heuristic: monthly rent should equal or exceed 1% of the purchase price. For example, a $200,000 property should rent for at least $2,000/month, or $24,000/year, giving a 12% gross yield. This rule is conservative and mostly applies to affordable markets. In expensive markets, 0.5-0.7% is more realistic. The 1% rule is a fast filter, not a substitute for detailed yield and cash flow analysis. The OnSumo rental ROI calculator can help you move from the 1% rule to a full return model.
