Rental Yield Calculator Formula
Understand the math behind the rental yield calculator. Each variable explained with a worked example.
Formulas Used
Gross Rental Yield
gross_yield = (annual_rent / property_price) * 100Net Rental Yield
net_yield = (net_income / property_price) * 100Annual Net Income
annual_net_income = net_incomeVariables
| Variable | Description | Default |
|---|---|---|
property_price | Property Purchase Price(USD) | 300000 |
monthly_rent | Monthly Rental Income(USD) | 2500 |
annual_expenses | Annual Operating Expenses(USD) | 6000 |
annual_rent | Derived value= monthly_rent * 12 | calculated |
net_income | Derived value= annual_rent - annual_expenses | calculated |
How It Works
Rental Yield Explained
Rental yield measures the annual return a property generates from rent relative to its purchase price.
Formulas
Gross Yield = (Annual Rent / Property Price) x 100
Net Yield = (Annual Rent - Expenses) / Property Price x 100
Key Differences
Worked Example
A $300,000 property rents for $2,500/month with $6,000 annual expenses.
- 01Annual rent: $2,500 x 12 = $30,000
- 02Gross yield: $30,000 / $300,000 x 100 = 10.00%
- 03Net income: $30,000 - $6,000 = $24,000
- 04Net yield: $24,000 / $300,000 x 100 = 8.00%
When to Use This Formula
- Comparing investment properties in different neighborhoods or cities where purchase prices vary widely — yield normalizes return relative to cost.
- Screening potential rental properties quickly before doing a full cash flow analysis — a gross yield below 5% in most markets signals the property will not cash-flow without significant appreciation.
- Evaluating whether to raise rent by calculating the current yield and comparing it against market averages for similar properties.
- Deciding between investing in rental property versus stocks or bonds by comparing the rental yield (plus expected appreciation) against alternative investment returns.
- Assessing the impact of a property price increase on future investors — as prices rise and rents stay flat, yield compresses, signaling a potentially overheated market.
Common Mistakes to Avoid
- Using gross yield when net yield is what matters — gross yield ignores vacancies, maintenance, insurance, property taxes, and management fees. A property with 8% gross yield might have only 4-5% net yield after expenses.
- Including personal mortgage payments in the yield calculation — rental yield measures the property's return independent of how you financed it. Mortgage payments are a financing decision, not a property characteristic.
- Using annual rent without accounting for realistic vacancy — assuming 12 months of rent when the market average is 5-10% vacancy overstates income and yield. Use 10.5-11 months of effective rent.
- Comparing gross yields across different markets without adjusting for expense ratios — a market with high property taxes and insurance (like Texas) has a much larger gap between gross and net yield than a low-tax market.
Frequently Asked Questions
What is a good rental yield?
A gross yield of 7-10% is generally considered good. Net yields above 5% are attractive. However, yields vary by market; high-yield properties may carry more risk or be in less desirable areas.
Is rental yield the same as ROI?
Not exactly. Rental yield only considers rental income relative to property price. ROI may also include appreciation, tax benefits, and leverage effects, giving a more complete picture of total returns.
Should I use gross or net yield?
Net yield is more useful for investment decisions since it reflects actual income after expenses. Gross yield is helpful for quick initial screening and comparisons between properties.
