Capitalization Rate - Cap Rate

Definition

Capitalization Rate (Cap Rate)

Capitalization rate, commonly called cap rate, is a real estate metric used to compare a property's annual net operating income with its value or purchase price.

It is commonly used when analysing income-producing properties, particularly rental real estate.

What Is Cap Rate?

Cap rate shows the relationship between the income a property generates from its operations and the value of the property.

It is normally expressed as a percentage.

Investors may use cap rate to compare different properties and understand how much operating income a property produces relative to its price.

Cap Rate Formula

A common cap rate formula is:

Cap Rate = Net Operating Income ÷ Property Value × 100

For example, suppose a property has:

  • Property value: 1,000,000
  • Annual rental income: 80,000
  • Annual operating expenses: 20,000

The net operating income would be:

80,000 - 20,000 = 60,000

The cap rate would then be:

60,000 ÷ 1,000,000 × 100 = 6%

In this example, the estimated cap rate is 6%.

What Is Net Operating Income?

Net Operating Income, often called NOI, is generally the income generated by a property after relevant operating expenses are deducted.

Operating expenses may include items such as:

  • Property management
  • Maintenance
  • Insurance
  • Property taxes where applicable
  • Service charges
  • Other normal operating costs

Mortgage payments and financing costs are generally treated separately when calculating a basic property cap rate.

How Do Investors Use Cap Rate?

Cap rate can help investors compare income-producing properties using a common percentage.

It may be useful when comparing:

  • Rental apartments
  • Houses used as rental properties
  • Commercial real estate
  • Multifamily properties
  • Other income-producing property

However, cap rate should not be used as the only measure when evaluating an investment.

Is a Higher Cap Rate Better?

A higher cap rate means the property is producing more net operating income relative to its value.

However, a higher cap rate does not automatically mean a better investment.

Differences in cap rate may reflect factors such as:

  • Location
  • Property condition
  • Tenant demand
  • Vacancy risk
  • Building age
  • Market conditions
  • Expected future growth
  • Property-specific risks

Cap rates should therefore be considered together with other financial and property information.

Cap Rate vs Rental Yield

Cap rate and rental yield are related but are not always calculated in exactly the same way.

Rental yield typically compares rental income with the property's value or purchase price.

Cap rate generally focuses on net operating income after operating expenses.

The exact calculation method used by investors can vary, so always check which expenses have been included.

Cap Rate vs Cash-on-Cash Return

Cap rate measures property operating income relative to property value.

Cash-on-cash return, by comparison, looks at annual cash flow relative to the amount of cash actually invested.

Because financing can affect cash-on-cash return, two investors purchasing the same property with different financing structures may have different cash-on-cash returns while the property's cap rate remains the same.

What Can Affect Cap Rate?

Several factors may influence cap rates within a real estate market, including:

  • Property prices
  • Rental income
  • Operating expenses
  • Location
  • Property type
  • Interest rates
  • Local supply and demand
  • Property condition
  • Market expectations

Cap rates can therefore change over time.

Why Cap Rate Is Useful

Cap rate provides a relatively simple way to compare the operating performance of different income-producing properties.

It can help investors ask questions such as:

  • How much operating income does this property generate?
  • How does it compare with another property?
  • Are operating expenses reducing the property's income significantly?
  • Does the property's income appear reasonable relative to its value?

It is best used as one part of a broader property investment analysis.

Important Information

Cap rate is an analytical metric and does not predict future property performance or guarantee investment returns.

Frequently Asked Questions

What does cap rate mean in real estate?
Cap rate is a percentage that compares a property's annual net operating income with its value or purchase price.
How do you calculate cap rate?
A common formula is Net Operating Income divided by Property Value, multiplied by 100.
Is a higher cap rate always better?
No. A higher cap rate may indicate more income relative to property value, but it can also reflect higher risk, weaker location, property condition or other market factors.
Does cap rate include mortgage payments?
Basic cap rate calculations generally use net operating income before mortgage payments and financing costs.
What is the difference between cap rate and rental yield?
Rental yield commonly compares rental income with property value, while cap rate generally uses net operating income after relevant operating expenses.
Can cap rate be used to compare properties?
Yes. Cap rate can help compare income-producing properties, but it should be considered together with location, condition, financing, vacancy, expenses and other investment factors.
