How to Use This Calculator
Enter the property investment value you want to use as the denominator. Add the rent and select the period represented by that rent. Enter expected occupancy and annual operating expenses paid by the property owner. The calculator annualizes the rent and shows gross and net rental yield.
How Gross Rental Yield Is Calculated
Gross Rental Yield = Annualized Potential Rent ÷ Property Investment Value × 100
How Net Rental Yield Is Calculated
Net Operating Rental Income = Effective Rental Income − Annual Operating Expenses
Net Rental Yield = Net Operating Rental Income ÷ Property Investment Value × 100
Gross Yield vs Net Yield
Gross yield is a quick comparison measure because it uses potential rent before operating expenses. Net yield goes further by allowing for occupancy and the operating costs entered by the user. A property with an attractive gross yield can have a much weaker net yield if vacancy or operating costs are high.
Property Investment Value
The denominator matters. Using only the purchase price can produce a different yield from using the total acquisition cost including transaction expenses. The calculator does not force one definition; it asks the user to choose the investment basis appropriate to the analysis.
What Expenses Should Be Included?
Include recurring property-level operating expenses relevant to earning the rental income, such as owner-paid management, maintenance, service or other operating costs. Mortgage principal and interest are intentionally excluded because financing structure belongs in cash-flow and ROI analysis rather than the underlying property yield.
Rental Yield in Nigeria
Rental income, occupancy, maintenance costs and property values can vary materially by Nigerian city, neighbourhood and property type. Avoid treating a yield based on asking rent or asking price as confirmed performance. Where possible, use transaction-specific and independently verified figures.

Frequently Asked Questions
What is gross rental yield?
Gross rental yield is annualized potential rent divided by the property investment value, expressed as a percentage.
What is net rental yield?
Net rental yield uses effective rental income after the occupancy assumption and subtracts entered operating expenses before dividing by property investment value.
Should I use purchase price or total acquisition cost?
Either can be analysed, but they answer slightly different questions. Use the cost basis that matches your investment analysis and state it consistently.
Does rental yield include mortgage payments?
No. Financing is excluded so the calculator measures property-level yield. Use a cash-flow or ROI calculator to analyse financing effects.
How does vacancy affect net yield?
Lower expected occupancy reduces effective rental income and therefore lowers net yield.
Can net rental yield be negative?
Yes. If entered annual operating expenses exceed effective rental income, net operating income and net yield can be negative.
Does a high rental yield mean a property is a good investment?
Not necessarily. Yield is one measure and does not by itself capture property condition, risk, appreciation, liquidity, financing, legal issues or future expenses.
