Last Updated: 

January 2, 2024

According to several real estate investor surveys, more than 65% prioritise cap rates. They consider it a pivotal factor in evaluating and analysing real estate investments. Understanding the basics of the cap rate and how it influences investment strategies is vital for real estate investors. Knowledge about real estate cap rates helps to make informed decisions when trading assets in the marketplace. The article highlights a comprehensive view of cap rates and their use in the real estate sector.

Key Takeaways on Calculating Cap Rates in Real Estate

  1. Cap Rate Essentials: Cap rate, or capitalisation rate, is a crucial metric for real estate investors, representing the potential return on investment (ROI) for a property.
  2. Calculation Clarity: Understanding cap rates involves calculating the ratio of Net Operating Income (NOI) to the property's current market value, offering insight into potential ROI.
  3. Higher Cap Rate ≠ Always Better: While a higher cap rate suggests a higher ROI, it doesn't guarantee better investment. Investors must consider various factors beyond cap rates for informed decision-making.
  4. Accurate NOI Determination: Calculating the Net Operating Income accurately is pivotal, comprising overall income minus operational costs like insurance, property taxes, and maintenance.
  5. Market Value Anticipation: Anticipating a property's market value involves practical research and comparison with similar properties, directly impacting the resulting cap rate.
  6. Risk and ROI Assessment: Cap rates aid in evaluating risks associated with real estate investments. High cap rates signal higher risk, while lower cap rates indicate lower risk, helping investors balance their risk and return profiles.
  7. Future Income Estimation: Cap rate metrics assist in forecasting potential income by considering market conditions, rental prices, property appreciation, and other factors, providing investors with valuable insights.

What is a Cap Rate?

Capitalisation rate or cap rate is a metric that real estate investors use to assess their potential ROI (return on investment). They calculate the rate by dividing their property's NOI (net operating income) by the present market value. The intention is to anticipate the ROI an investor expects from investing in a specific real estate property. The cap rates also help compare the potential property investments and determine which generates the highest return. A higher cap rate means a higher ROI, which is a favourable option. However, a higher cap rate doesn’t always indicate better investment. Other factors should come into the limelight when assessing a potential real estate investment.

How to Calculate Cap Rates?

Understanding Cap Rate

It is the ratio of NOI (net operating income) of the real estate property to the property’s present market value.

The formula expresses:

Cap Rate= Net Operating Income/ Present Value of the Property

The higher the cap rate, the higher the ROI. The cap rate is the anticipation of the potential ROI, not an assurance of future performance or returns.

Determining the NOI

The first step in measuring the cap rate is determining the net operating income (NOI). The net operating income is the overall income generation minus the operations costs, like insurance, property taxes, and maintenance. Calculating the NOI should be accurate as it directly influences the cap rate. 

Anticipating the Market Value

The next step involves anticipating the property’s market value. It is done by researching and comparing different properties in the locality. The real estate investor should be practical when anticipating and calculating the property's market value, as it directly impacts the cap rate.

Calculating Cap Rate

The real estate investor calculates the cap rate after determining the net operating income (NOI) and present market value. The formula for calculating the cap rate is:

Cap Rate= (NOI/Present Market Value)/100

The formula expresses dividing the net operating income (NOI) by the current market value and multiplying the result by 100 to acquire the cap rate as a percentage.

Assessing the Result

The final step involves assessing the outcome. The high cap rate means a higher potential ROI, and the low cap indicates low potential. Cap rate is one of the factors that determine the potential ROI. A real estate investor should consider other elements like the property’s condition, location, market value, and cap rate to determine the potential return on income.

Why are Cap Rates Vital in Real Estate Investing?

Determining the Value of a Property

Cap rate is an effective and quick method to determine the property’s value. It concerns the NOI and the purchasing price to identify the percentage indicating the property’s ROI. The calculation helps investors to understand whether a property is expensive or underpriced and make informed decisions.

Evaluating Risks and ROIs

Cap rates assess the risks related to real estate property investments. Properties with high cap rates are high-risk investments, and low cap rates are less risky. The data helps investors balance the risk factors and ROIs in their profiles.

Estimate Future Income

Cap rate metrics help investors anticipate potential income generation from real estate investments. The current cap rate helps to predict the potential income from factors like market conditions, market change, rental price, and property appreciation.


The cap rate is an extensive practice in real estate investing. Basic understanding and knowledge of cap rates provide investors with valuable data about the potential of a property’s future income. Real estate investors should know ways to use the cap rates and assess potential investments. When combined with other metrics like ROI and cash flow, cap rate is an excellent tool for making informed investment decisions.
