@RISK
Perform Monte Carlo simulations to quantify uncertainty.
@RISK is Excel-based risk analysis software using probability and simulation to model outcomes, assess likelihoods, and support confident decisions. It helps quantify, manage, and communicate risk across finance, engineering, insurance, and healthcare.
Features
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.
graphs and reports
@RISK offers a wide variety of customizable, exportable graphing and reporting options that let you communicate risk to all stakeholders.
extensive modelling features
With a broad library of probability distributions, data fitting tools, and correlation modelling, @RISK lets you represent any scenario with the highest level of accuracy.
Use Cases
Explore insights that inspire impact - with @RISK
Investment Portfolio Optimization
Simulate multiple portfolio assets to maximize return while minimizing risk.
Cost Estimation
Get an accurate probabilistic estimate of materials and labor costs throughout the entire project.
Engineering Reliability
Six Sigma calculations provide insight into confidence levels on risk of failure or safety violations.
Industries
Energy & Utilities
@RISK is used to model uncertainty in capital investments, energy demand forecasting, pricing volatility, and infrastructure reliability.
Insurance
By simulating thousands of scenarios, organizations can better understand exposure to catastrophic events, pricing uncertainty, claims volatility, and portfolio risk.
Manufacturing
By running Monte Carlo simulations, manufacturers can evaluate risks related to supply chain disruptions, equipment downtime, and fluctuating raw material costs, enabling more resilient and data-driven operational decisions.
Construction and engineering
Construction and engineering firms use @RISK to analyze uncertainty in project schedules, budgets, and resource allocation.
Aerospace and defence
In aerospace and defense, @RISK supports risk analysis for complex, high-value programs involving long timelines and strict performance requirements.
Sales
By simulating multiple sales scenarios, organizations can better understand revenue risk, optimize targets, and make informed strategic decisions under changing market conditions.
