Risk analysis using Monte Carlo simulation for Microsoft Excel

From the financial to the scientific, anyone who faces uncertainty in their quantitative analyses can benefit from @RISK. @RISK helps both Fortune 100 companies and private consultancies paint a realistic picture of possible scenarios. This allows businesses to not only buffer risks, but also identify and exploit opportunities for growth.


@RISK (pronounced “at risk”) is an add-in to Microsoft Excel that lets you analyze risk using Monte Carlo simulation. @RISK shows you virtually all possible outcomes for any situation—and tells you how likely they are to occur. This means you can judge which risks to take on and which ones to avoid—critical insight in today’s uncertain world.
