An Excel add-in for Monte Carlo simulation that explains its results
Simulate your spreadsheet model
Uncertain inputs are ordinary cell formulas, such as =XMC.Triang(80, 100, 140). The workbook still works without the add-in, and it never leaves your computer.
See what drives the output
Simulation decomposition (SimDec) splits the outcome distribution into scenarios based on the most influential inputs, so you see which combinations of inputs produce each part of it.
See whether the drivers are stable
The heterogeneity index detects whether the drivers change across the model regions and regional sensitivity profiles show how exactly.
Join the waitlist
The beta version is now being tested in several pilots. Leave your email, and we'll write when it opens to more users.
Public release planned for spring 2027
Built on open research
The methods behind the add-in have been developed in peer-reviewed research since 2017. The research code is open source.
