What Is A Good Cap Rate & How To Calculate It

Key Takeaways:

A cap rate, otherwise known as a capitalization rate, is one of the most important fundamental indicators for determining whether a property is worth pursuing. Not surprisingly, cap rates have proven instrumental in building some of today’s most prolific real estate investment portfolios, and there’s no reason it couldn’t help you do the same. In fact, I’d argue that you can’t even build a halfway decent portfolio without asking, “what is a good cap rate?” It’s that important. Therefore, it’s in your best interest to better understand what a cap rate is and how to use it to strengthen your investing efforts.

What Is Cap Rate?

Cap rate is one of the easiest and most dependable ways to quantify whether or not an investment deal is worth following through with. In its simplest form, a cap rate is nothing more than an equation, one that will identify how much an investor stands to make or lose if they end up buying the property in question. However, it is worth noting that a cap rate won’t provide investors with the exact amount they stand to gain but rather an estimate. As a result, cap rates are no more accurate than stock market predictions; they are subject to an inherent degree of error and should be taken with a grain of salt. I repeat, cap rates are not 100% accurate; they are merely used to estimate one’s potential return on their investment. That said, a properly estimated cap rate is invaluable when supported with due diligence and acute attention to detail.

Cap rates are not intended to act alone and should instead be used in conjunction with other metrics. A cap rate by itself is almost useless. Still, a cap rate with supplemental data and information can significantly mitigate the amount of risk an investor will be exposed to over the course of an investment. Therein lies the benefit of learning how to calculate cap rate: the resulting number can mitigate more risk than many investors realize. If you know how much an investment could potentially make, it stands to reason you’ll know whether or not you should pull the trigger on the purchase.

What Is A Good Cap Rate For Rental Property?

A good cap rate hovers around four percent; however, it is important to differentiate between a “good” cap rate and a “safe” cap rate. This is because the formula itself puts net operating income in relation to the initial purchase price. Investors hoping for deals with a lower purchase price may, therefore, want a high cap rate. Following this logic, a cap rate between four and ten percent may be considered a “good” investment.

However, capitalization rates have also become synonymous with a risk evaluation. To determine a “safe” cap rate, you must identify how much risk you are comfortable exposing yourself to. Essentially, a lower cap rate implies lower risk, while a higher cap rate implies higher risk. Investors hoping for a safer option would, therefore, favor properties with lower cap rates. The most important thing to remember is that you should never take on more risk than you are comfortable with, and you should always use cap rate in addition to other calculations.

When Is Cap Rate Used And Why Is Cap Rate So Important?

Cap rate is used by investors deciding whether or not to move forward with a given property. In some cases, it may also be used by investors preparing to sell a property. Cap rate works best for rental properties and may not be as helpful in other scenarios. For example, investors should avoid relying on cap rate when evaluating raw land, fix and flip properties, and, in some cases, short term rentals. This is because the cap rate formula relies on annual net operating income, which would not be applicable. Investors (or even landlords) can, however, use cap rate when evaluating several property types, including:

  • Multifamily Rental Properties

  • Apartment Buildings

  • Single-Family Rental Homes

  • Rentable Townhouses

  • Commercial Real Estate

Cap rate is important because it can provide a look at the initial yield of an investment property. The formula puts net operating income in relation to the investment’s purchase price, which can put the potential profitability of the deal in perspective for investors. According to Investopedia, the cap rate can also reveal the number of years it will take to recover the initial investment. For example, a property with a 4 percent cap rate will take four years to recover the investment. Overall, cap rate is an important way for investors to estimate the level of risk associated with a given property.

How To Calculate Cap Rate: Capitalization Rate Formula

(Net Operating Income / Current Market Value) X 100 = Capitalization Rate

For as important as cap rates are, they aren’t as complicated to calculate as you would assume. In fact, learning how to calculate cap rate requires nothing more than basic math skills or a free cap rate calculator. Although, before you start calculating your own cap rate, you’ll need two things:

  • The property’s net operating income (NOI)

  • The amount it would cost to by the property

It is worth pointing out that calculating a property’s market cap is contingent on gathering accurate information. Therefore, you will need to mind due diligence and make certain that you can pinpoint the net operating income. To do so, estimate the rental property’s annual revenue (using rental income) and then subtract the total operating expenses. For more information on how to accurately estimate net operating income, be sure to read this article.

Cap Rate Vs ROI

The main difference between cap rate and ROI is what the two metrics are used for. As I have already alluded to, cap rate estimates the investor’s potential return on investment (ROI). That said, it’s not hard to see why many entrepreneurs confuse the two. The two metrics are very similar; they tell an investor what to expect if they move forward with an investment. It is worth noting, however, that cap rate and ROI serve a different purpose when analyzing a deal.

Return on investment is meant to give investors an objective percentage of how much they can expect to make a deal. For example, ROI is typically expressed as a percentage to estimate the investor’s potential return on their investment. That way, investors can compare the ROIs of two completely different assets. In addition, the return on an investment expressed as a percentage makes it easier to compare two individual assets, whether they are the same. Investors can, therefore, compare the ROI of a three-month rehab with a 30 year buy and hold.

The cap rate, on the other hand, is used to compare similar real estate assets. For example, a cap rate would be perfect for someone to compare returns from two rental properties, but far from ideal for investors who want to compare a rental property to a rehab.

Cap Rate Example

Calculating the cap rate is relatively simple if you have the property’s net operating income (NOI). Remember to calculate NOI, subtract all expenses related to the property, excluding mortgage interest, depreciation, and amortization, from the property’s income. To explain this, let’s use a simple example.

Say you purchase a property for $1,000,000; it grosses $100,000 through rent and has total expenses of $30,000. Your NOI would be $70,000 ($100,000 – $30,000). To calculate cap rate, divide the NOI of $70,000 by the purchase price of $1,000,000 giving you a 7% cap rate. Calculation can be broken down as follows:

  • Purchase Price

  • $1,000,000

  • Property Income

  • $100,000

  • Property Expenses

  • $30,000

  • NOI

  • $100,000 – $30,000 = $70,000

  • Cap Rate

  • $1,000,000 / $70,000 = 0.07

    0.07 X 100 = 7%

Can Cap Rate Change?

Cap rate can change as long as investors understand how to boost the NOI. This process is sometimes referred to as compressing cap rates. It involves purchasing a property for below market value and renovating it to boost the overall NOI (typically by increasing the rental income). Renovations can also raise the property value — especially in the right market conditions. The property, which would then have a lower cap rate, could be held or sold for a profit. Remember, as an investor, you have a lot of control over the performance of a given property. With the right planning and execution, you can change the cap rate and boost your portfolio in the process.

The Gordon Model For Cap Rate

The Gordon Growth Model, also known as the dividend discount model, is another form of cap rate that you should be familiar with. It is used to calculate the inherent value of a company’s stock price. The formula looks like this:

(Required Rate of Return – Expected Growth Rate) = Expected Cash Flow / Asset Value

In this formula, the expected cash flow equates to the NOI, and asset value represents the property’s market price. This means that the cap rate is simply the difference between the rate of return and the expected growth rate.


An investment property cap rate may sound simple, but its implications are heavily weighted. That’s why it’s crucial to expand your real estate education and ask questions like “what is a good cap rate?” After all, those who equip themselves with the best investing tools—like cap rates—stand a better chance at realizing success in the industry.
