What Is Rental Yield and How Do You Calculate It?

Buying a property and renting it out can generate a steady income, but how do you know whether the investment is actually worth the money? One of the simplest ways to evaluate its income potential is through rental yield. It tells you how much rental income a property generates compared with its purchase price or market value, expressed as a percentage.

For anyone considering property investment in Nigeria, understanding this figure can make it easier to compare apartments, houses and commercial properties before committing millions of naira. TheHouse48 provides property insights that can help buyers and investors make more informed decisions.

What Exactly Is Rental Yield?

Rental yield measures the annual rental income generated by a property relative to its value or acquisition cost.

For example, if you purchase an apartment for ₦50 million and collect ₦4 million in rent over a year, the property generates an 8% gross rental yield.

However, there are two main types of rental yield: gross and net. Understanding the difference is important because the first calculation does not account for the expenses involved in owning and managing a rental property.

How to Calculate Gross Rental Yield

Gross rental yield is the simplest version of the calculation. It compares the annual rent with the property's purchase price or current market value, without deducting expenses.

The formula is:

Gross Rental Yield = (Annual Rental Income ÷ Property Price) × 100

Consider this example:

• Property purchase price: ₦50,000,000

• Annual rental income: ₦4,000,000

Calculation:

₦4,000,000 ÷ ₦50,000,000 × 100 = 8%

This means the property has a gross rental yield of 8%.

Gross yield is useful when comparing several properties quickly, but it does not tell you how much money you will actually retain after paying for maintenance, management and other expenses.

How to Calculate Net Rental Yield

Net rental yield provides a more realistic picture because it accounts for the costs of operating the property.

These expenses may include repairs, maintenance, property management fees, insurance, service charges, estate levies and applicable property taxes. You should also account for periods when the property is empty and not generating rental income.

The formula is:

Net Rental Yield = ((Annual Rental Income − Annual Expenses) ÷ Property Price) × 100

Using the previous example, assume the property generates ₦4 million annually but costs ₦800,000 per year to maintain and manage.

• Annual rent: ₦4,000,000

• Annual expenses: ₦800,000

• Income after expenses: ₦3,200,000

• Property price: ₦50,000,000

Calculation:

₦3,200,000 ÷ ₦50,000,000 × 100 = 6.4%

Although the property has an 8% gross yield, its net rental yield is 6.4%.

This difference explains why investors should look beyond the rental income advertised by sellers and developers.

What Is Considered a Good Rental Yield?

There is no universal percentage that makes a property investment good. Rental yields vary according to location, property type, purchase price, tenant demand and operating expenses.

An apartment in a high-demand neighbourhood may command substantial rent, but its purchase price could also be considerably higher. Meanwhile, a cheaper property in another location might produce a higher percentage return but experience longer vacancies or greater maintenance costs.

Investors should compare properties in similar locations and consider both rental income and the potential for long-term appreciation.

Does Rental Yield Tell You Everything?

Not quite. Rental yield measures income relative to property value, but it does not automatically show whether you will make a profit after financing costs, taxes or the eventual sale of the property.

For instance, a landlord paying a mortgage must also consider loan repayments when assessing personal cash flow. A property can have an attractive rental yield and still leave its owner struggling to cover monthly expenses.

This is particularly relevant when comparing traditional long-term rentals with short-term accommodation. The financial differences between Airbnb and traditional landlords can help illustrate how different rental strategies affect income and operating costs.

TheHouse48 helps property buyers, landlords and investors explore the financial considerations behind real estate decisions. Before purchasing a rental property, calculate both gross and net yield, investigate the local rental market and make sure the expected income justifies the total investment.
