# @Risk

## Probabilistic Risk Analysis in Excel

From the financial to the scientific, anyone who faces uncertainty in their quantitative analyses can benefit from @RISK. What are the chances of making money –or taking a loss–on your next venture? How about the probabilities of staying within budget or needing a contingency? With @RISK, you can answer these risk modelling questions and more – right in your Excel spreadsheet.

• Integrates with Microsoft Excel
• Avoid pitfalls and uncover opportunities with Risk Analysis
• Communicate risk to others

## Use Monte Carlo Simulation to see all possible outcomes

@RISK (pronounced “at risk”) software is an add-in tool for Microsoft Excel that helps you make better decisions through risk modelling 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 and shows you the probability of each occurring. 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.

## Model risks and uncover new opportunities

From the financial to the scientific, anyone who faces uncertainty in their quantitative analyses can benefit from @RISK. @RISK helps both Fortune 500 companies and private consultancies paint a realistic picture of possible scenarios. This allows businesses to not only buffer and mitigate risks but also identify and exploit growth opportunities.

• Model Risk Factors and Protect Yourself with Contingency Planning
• Plan Better Strategies
• Avoid Pitfalls and Uncover Opportunities with Risk Analysis

## Key features in @Risk

### 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 that you can plan strategies—and resources—accordingly.

### Graphs and Reports

@RISK offers various 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 modelling, @RISK lets you represent any scenario in any industry with the highest level
of accuracy.

## What’s new in @RISK 8?

### A New Generation in Risk Analysis

@RISK 8 is a major upgrade representing the culmination of feedback from thousands of users. We focused on what is most important to you based on the analyses you do every day. Furthermore, @RISK 8 has been rebuilt on the latest programming technology from the ground up. This forward-looking foundation ensures that @RISK will continue to provide the most reliable, accurate, and robust quantitative risk analysis available anywhere for years to come.

But make no mistake: while @RISK 8 is better, faster, and stronger than ever, it is still as easy to use as 1-2-3.

### Fresh new look, Streamlined workflows

As a result of user input, the interface is now more intuitive for both new and experienced practitioners alike, reducing learning curves and the time it takes to perform analyses. @RISK 8 offers a thoroughly modern look and feel throughout the entire application, from the all-new command Ribbon to every dialogue window. What’s more, @RISK 8 is available in both English and Spanish.

### Faster performance

All costs are the lowest possible value, and sales revenues are the highest of possible projections. The outcome is making a lot of money.

### Easier modelling

The Define Distribution window, the first step in any @RISK analysis, has been overhauled to simplify anything you may need to do when creating or editing @RISK distribution functions. Correlations are much faster to define, and the performance of time series fitting has been significantly enhanced. Plus, the entire Model Window is more flexible and simpler than ever.

### Communicate and share results more clearly

From Summary Trend to 2-Way Tornado charts, @RISK 8 offers significantly improved graphing capabilities, as well as an entirely new feature set for generating custom reports to share with colleagues. The best part is, it does all this 10 times faster than before! A new Explore menu offers all results graphs and reports in one place. And the Browse, Summary, and other windows have been overhauled for faster workflows.

### Get started fast

All costs are the highest possible value, and sales revenues are the lowest of possible projections. The outcome is losing money.

### Solid analytics and tight Excel integration

Of course, another key reason Fortune 1000 companies rely upon @RISK every day has long been the power of its rock-solid analytics. Version 8 takes that up a level, too, with substantial enhancements to sophisticated analytical features. In addition, @RISK 8 supports the very latest advances in Excel 2019 (such as dynamic arrays) to make your analyses even more cohesive.

While @RISK 8 is a substantial upgrade in its own right, it also represents the birth of a new platform which will launch an entire generation of risk analysis advances. The new @RISK is technologically poised to take advantage of future improvements in the field of probabilistic analysis and Excel itself. Put simply, this ensures you can trust that @RISK will provide the best possible insights, whatever the future brings.

## System requirements

### Operating Systems

@RISK requires Windows 7 (SP1 or later), Windows 8, Windows 10 or Windows 11.

While there is no support for running on the native Macintosh OS, @RISK will run on a Windows environment hosted on the Mac. The following configurations are supported:

• Windows 7 through Windows 10 running, using Boot Camp.
• Windows 7 through Windows 10 emulation using Parallels, VirtualBox, or VMware.

An installed copy of Microsoft Excel 2010, 2013, 2016 or 2019 for Windows or Office 365 for Windows is required. Palisade add-ins will not run with earlier versions of Microsoft Excel.

The software is compatible with the “On Premises” deployment option of Office 365. It is not compatible with the “Office on Demand” or “Office Web Apps” deployment options.

@RISK is not compatible with non-Microsoft spreadsheet packages.

### Visual C++ Runtime Files

Palisade add-ins require the Microsoft Visual C++ “Universal” Runtime. On a 64-bit machine, both the 64-bit and 32-bit versions of this library are required. On a 32-bit machine, only the 32-bit version of this library is required. These will be installed automatically as part of the DTS installation if they are not found on the system.

### Microsoft .NET Framework 4.6.1

Palisade software requires Microsoft .NET Framework 4.6.1. In Windows 7, the DecisionTools Suite installer will automatically install this component. In Windows 8 and Windows 10, the .NET Framework 4.0 is already installed as part of Windows. The .NET framework will be installed automatically as part of the DecisionTools Suite installation if it is not found on the system.

## Licensing

All Palisade software is sold on a subscription license basis. Subscription licenses allow you to invest at a level that works for your budget and can be categorized as an operating expense.
