Risk rating is a critical aspect of risk management that aids in evaluating and categorizing potential risks within a project, business, or any operational environment. It involves a comprehensive analysis of various factors to determine the likelihood and impact of these risks, thereby allowing organizations to prioritize their mitigation strategies effectively.

Introduction to Risk Rating

Understanding risk assessment forms the cornerstone of effective risk management. It involves the identification, analysis, and evaluation of potential risks that can impact an organization’s objectives. Risk rating plays a pivotal role in this process by providing a structured approach to quantify and categorize risks based on their severity.

Components of Risk Rating

Identifying Risk Factors

The first step in calculating risk rating involves identifying and listing potential risk factors. These factors can vary widely depending on the nature of the project or business, encompassing aspects such as market volatility, financial risks, operational challenges, and regulatory changes.

Creating a Risk Matrix

A risk matrix is a visual representation that maps the likelihood of an event occurring against its potential impact. This matrix is typically divided into various risk levels, aiding in the classification of risks as low, medium, or high.

Defining Risk Levels

Each quadrant of the risk matrix corresponds to a specific risk level. Low-risk events are those with minimal impact and low probability, while high-risk events pose a significant threat and have a higher likelihood of occurrence.

Calculating Risk Rating

Assessing risk involves evaluating the probability of an event occurring and its potential impact on the organization. This evaluation is often done using numerical values assigned to both probability and impact, which are then plotted on the risk matrix.

Interpreting Risk Levels

Interpreting the risk levels determined through the matrix is crucial. Low-risk events may not require immediate action but necessitate monitoring, while high-risk events demand immediate attention and mitigation strategies.

Implementing Risk Rating

Integrating risk rating into decision-making processes is vital. Organizations need to consider the assessed risk levels when strategizing, allocating resources, and planning for contingencies.

Calculating a risk rating or determining a risk level typically involves using a risk matrix, which is a tool that assesses the likelihood and impact of a risk to determine its overall level of risk. Here's a step-by-step guide:

Steps to Calculate Risk Rating using a Risk Matrix:

  1. Identify Risks: List the potential risks associated with a project, situation, or scenario.
  2. Determine Likelihood: Assess the probability or likelihood of each risk occurring. You can use a scale (e.g., low, medium, high) or assign numerical values (e.g., 1-5, with 1 being least likely and 5 being most likely).
  3. Assess Impact: Evaluate the potential impact or consequences of each risk if it were to occur. Again, use a scale or numerical values to measure the severity of impact.
  4. Create a Risk Matrix: Construct a grid or matrix with the likelihood on one axis (usually horizontal) and impact on the other axis (usually vertical). The matrix will have different levels or categories for likelihood and impact.
  5. Assign Ratings: Place each identified risk within the matrix based on its likelihood and impact assessment.
  6. Determine Risk Rating: Once each risk is plotted on the matrix, the intersection or position on the grid will indicate its risk rating or level. Generally, risks found in the higher likelihood and higher impact area pose the most significant threat and are labeled as high risk. Risks in lower likelihood and lower impact areas may be low risk.
  7. Mitigation Strategies: Based on the risk ratings, prioritize risks that require attention and develop mitigation or risk management strategies for high and moderate-risk areas.
  8. Regular Review: Periodically review and update the risk matrix as circumstances change or new information becomes available.


Let’s say you have a risk matrix with likelihood ratings of Low, Medium, High (1-3) and impact ratings of Low, Medium, High (1-3).

  • If a risk has a high likelihood (3) and a high impact (3), it would be positioned in the top right quadrant of the matrix, signifying it as a high-risk item.
  • A risk with low likelihood (1) and low impact (1) would be placed in the bottom left quadrant, indicating a low-risk item.
Remember, the specific criteria for likelihood and impact, as well as the layout of the matrix, can vary depending on the organization or context. Adjust the scales and categories based on what best fits your needs.

In a dynamic business landscape, understanding how to calculate risk rating through a risk matrix is crucial for informed decision-making and proactive risk management. By systematically assessing risks and assigning appropriate levels, organizations can prioritize their efforts and resources effectively to mitigate potential threats.


  1. What is a risk matrix, and how does it work? A risk matrix is a visual tool that helps assess risks by plotting their likelihood and impact on a grid. It works by assigning probabilities and impact levels to different scenarios, allowing organizations to categorize risks based on severity.
  2. How often should risk ratings be reassessed? The frequency of reassessment depends on various factors like the nature of the project, changes in the environment, or the occurrence of significant events. Generally, it’s good practice to review and update risk ratings periodically, ensuring they reflect current conditions.
  3. What are the main challenges in calculating risk rating? Challenges include subjective assessments, biases in evaluating risks, dealing with complex scenarios, and balancing multiple variables that affect the likelihood and impact of risks.
  4. Can software tools completely automate risk rating processes? While software tools assist in calculations and data management, human judgment and expertise are crucial in interpreting data, considering contextual factors, and making informed decisions. So, while they automate certain aspects, full automation isn’t advisable.
  5. Why is stakeholder involvement crucial in risk assessment? Stakeholders bring diverse perspectives and domain knowledge to risk assessment. Involving them ensures a comprehensive understanding of risks across different areas, enhances risk identification, and increases buy-in for mitigation strategies.
