Some of the key features

Monte Carlo simulation

Basic - Complete

ModelRisk has a comprehensive range of tools to run Monte Carlo simulations within Excel. Results are presented in a separate window that allows you to customize, save and share a comprehensive range of graphical and statistical analyses.


Basic - Complete

ModelRisk incorporates a truly complete range of distributions. Graphical interfaces, categorization by function, fitting to data and a detailed interactive guide on the theory and use of each distribution help ensure that you find the correct distribution for your problem. You can also create your own distribution using the shaper tool.


Basic - Complete

Modeling any correlated behavior between distributions is a critical component in risk analysis. ModelRisk allows the user to visualize and fit correlation structures to data through its copula tools. Through its unique approach to correlating variables, any number of distributions can be correlated. ModelRisk's own data copula offers a powerful way to replicate any unusual correlation pattern.

Time series

Basic - Complete

Uniquely, ModelRisk has built-in tools for simulating time series, together with graphical interfaces and fitting to data to ensure you understand and select the right time series model. The custom time series tools also let you create your own expert-based forecasts.

Database connectivity


ModelRisk’s DataObject tool allows the user to create links to unopened Excel files or various types of databases. An SQL wizard guides the user to select what is required from the database, and a preview feature shows the selected data. The data can then be used in various ways within ModelRisk, including fitting to distributions, correlation structures and time series models.

Ordinary Differential Equation tool


ModelRisk’s Ordinary Differential Equation (ODE) tool numerically evaluates a system of ordinary differential equations. The user can specify any differential equations that can be described with Excel functions. One or more time stamps (specific points in time) can be specified for the evaluation of the variable(s). The interface will plot any variable against time or any two variables together
