Powerful risk analysis for confident decision-making

Take control of uncertainty with @RISK—the tool that empowers your team to quantify and mitigate risks with confidence, all within Microsoft Excel. Whether you’re navigating financial markets, optimizing operations, or ensuring regulatory compliance, @RISK transforms complex uncertainties into actionable insights through Monte Carlo simulation—enabling data-driven decisions that drive business success.

How @RISK Works

@RISK (pronounced “at risk”) software is an add-in tool for Microsoft Excel that helps you make better decisions through risk modeling and analysis. It does this using a technique known as Monte Carlo simulation. @RISK’s Monte Carlo analysis computes and tracks many different possible future scenarios in your risk model, showing you the probability of each occurring. In this way, @RISK shows you virtually all possible outcomes for any situation. This probabilistic approach makes @RISK a powerful tool that you can use to judge which risks to take and which ones to avoid — critical insight in today’s uncertain world.

• Works with Microsoft Excel
• Avoid Pitfalls and Uncover Opportunities with Risk Analysis
• Plan Better Strategies
• Model Risk Factors and Protect Yourself with Contingency Planning
• Communicate Risk To Others

Endless Applications

As the pace of change in business continues to increase, organizations are challenged to increase margins and explore new opportunities for growth, all while reducing risk. @RISK is designed to meet these challenges.

• Investment Planning & Portfolio Optimization. Simulate multiple portfolio assets (such as stocks, bonds, real estate, or projects) to maximize return while minimizing risk. Calculate Value-at-Risk, or the probability of different losses on a portfolio.
• Cost Estimation. Get an accurate probabilistic estimate of materials and labor costs throughout the entire project. Understand the likelihood of going over budget under a variety of scenarios.
• Engineering Reliability. Using Six Sigma calculations, gain insight into confidence levels around the risk of equipment failure or safety violations. Identify areas of weakness to ensure quality results and prevent failures.
• Capital Reserves. Probabilistically forecast future claims or losses in order to determine optimal reserve levels. Perform stress testing on high-impact, low-probability events.
• Oil, Gas, & Mineral Reserves. Assess the likelihood of prospective sites containing oil, natural gas, metals, or other minerals. Probabilistically estimate reserves and production decline in order to make wise drilling decisions.

Get Insights for Better Decisions

While @RISK provides sophisticated analytics, don’t be intimidated. All techniques @RISK uses are intuitive applications that integrate seamlessly with your existing Excel spreadsheets and provide actionable results with point-and-click ease.

• Monte Carlo Simulation. By sampling different possible inputs, @RISK calculates thousands of possible future outcomes and the chances they will occur. This helps you avoid likely hazards — and uncover hidden opportunities.
• 100% Excel Integration. @RISK integrates seamlessly with Excel’s function set and ribbon, letting you work in a familiar environment with results you can trust.
• Sensitivity Analysis. @RISK identifies and ranks the most important factors driving your risks so you can plan strategies — and resources — accordingly.
• Graphs and Reports. @RISK offers a wide variety of customizable, exportable graphing and reporting options that let you communicate risk to all stakeholders.
• Extensive Modeling Features. With a broad library of probability distributions, data fitting tools, and correlation modeling, @RISK lets you represent any scenario in any industry with the highest level of accuracy.
