Calculating Capitalization Rate in Real Estate

Two words can make or break an investor’s decision to buy their next SFR investment or rental property; cap rate. Cap rate, also known as the capitalization rate, is the perfect formula to determine the potential income for a single-family residential (SFR) rental property. Instead of looking at only the monthly and annual income the investment property will yield, cap rate takes a broader look at the costs and expenses that occurs with owning a rental property — and gives the investor a better sense of the overall quality of the investment. 

In a recent article from, Bruce Ailon, a realtor and attorney from Alpharetta, Georgia is tells us that, “Cap rate is both a measure that tells you how much you are earning on the investment and a proxy for determining the risk of an investment.”

Finding the cap rate can be broken down into 3 simple steps.

1) Calculate the property’s annual rent
Calculating the property’s gross annual rent is simply taking the rent your tenants pay you each month and multiplying it by twelve to get your gross annual rent. This is the rent you collect before subtracting annual expenses for managing the property.

2) Subtract the annual expenses
Once you’ve calculated your gross annual rent, you’ll need to subtract your annual expenses. These expenses include utilities, maintenance, and any repairs that are required. After you’ve subtracted your annual expenses you have your net annual income of the property.

3) Divide net income by purchase price or market value
Now that you know the amount of your net annual income from the property, you’re ready to calculate your cap rate. To find the cap rate, you’ll need to divide the net income by the purchase price or current market value of the property.

Examples of How To Calculate Cap Rate

If a rental property is providing an investor a monthly rental income of $1,000 then the annual income will be $12,000. Pretty simple right?

The next step is to determine the property’s expenses and subtract that from the annual income. So let’s say that the example property we mentioned above has yearly expenses of $3,000.

Example how to calculate cap rate

Now that net income has been determined, the investor can divide net income by the purchase price. Let’s say the investor purchased this aforementioned property for $125,000. We would divide the net income ($9,000) by the property purchase price ($125,000) and are left with 0.072. Meaning 7.2% is the final cap rate and the expected annual return on investment for that property.

What Is A Good Cap Rate?

According to the same article, most real estate investors look for cap rates in the 4-12% range, with 4% being the absolute minimum for a potential rental property. Any investment property with a cap rate lower than 4% has greater potential for a loss if there are unforeseen maintenance issues with the property or long periods without tenants living in the property. By staying in the 4-12% cap rate range, investors can better estimate their returns and choose properties that will provide increased confidence and less risk in their investment.
