If you’re starting your real estate investment journey, you’ve probably heard the term cap rate. While it may sound like a complicated financial metric, it’s actually one of the most useful tools investors use to evaluate rental properties.
Cap rate helps estimate how much income a property can generate compared to its purchase price. Although it’s only one part of analyzing an investment, understanding this metric can help you compare opportunities more confidently.
Whether you’re considering a duplex in Springfield or a multi-family property in Chicopee, here’s what you need to know about cap rate.
Cap rate, short for capitalization rate, measures the expected annual return on an investment property based on its Net Operating Income (NOI) and its current market value or purchase price.
It’s commonly used to compare similar investment properties before making a purchase.
A higher cap rate may indicate greater potential returns, while a lower cap rate may reflect a more stable market or a property with lower perceived risk.
The basic formula is:
For example:
Cap Rate = ($28,000 ÷ $400,000) × 100 = 7%
This means the property generates an annual return of approximately 7% before financing costs and taxes are considered.
Imagine you’re comparing two apartment buildings.
Property A
Property B
Although Property B produces slightly more annual income, Property A generates a higher return relative to its purchase price.
This example shows why investors often compare cap rates when evaluating similar properties.
Before calculating cap rate, you first need to determine a property’s Net Operating Income (NOI).
NOI is calculated by taking the property’s annual rental income and subtracting its operating expenses.
Typical operating expenses include:
Mortgage payments are not included in NOI because cap rate measures the property’s performance independent of financing.
Cap rate helps investors:
It’s one of the first metrics many investors review before taking a closer look at a property’s financial details.
While cap rate is useful, it should never be the only factor influencing your decision.

A property with a strong cap rate may still be a poor investment if it requires significant repairs or is located in an area with declining demand.
Likewise, a property with a lower cap rate may still offer excellent long-term appreciation.
