ScenarioBuilder
Powered by Monte Carlo simulation

From Excel assumptions to thousands of possible financial outcomes—in minutes.

Give each assumption a realistic range. Scenario Builder runs 10,000 scenarios and shows the chance of hitting budget, the median outcome and the downside.

How it works

Four steps with easy Excel input.

01
Open your workbook

Start from the Scenario Builder workbook structure and add your driver logic and plan data.

02
Change your assumptions

Adjust any driver — price, churn, hiring, FX — as many as you like.

03
Click. Thousands of scenarios.

Every plausible combination of your assumptions, run in seconds.

04
One clear picture

The chance of hitting budget, and the range of outcomes. Instantly.

What actually happens

One assumption becomes thousands of scenarios

Your model normally holds one number for each assumption. We let each one move within a realistic range, sample thousands of combinations, and count where the result lands.

01
Give each driver a range

A low and a high you'd actually accept.

Sales volume: 3,600 – 4,700
02
The model samples 10,000 scenarios

Each run draws one combination from the ranges you defined. It samples possibilities; it does not test every possible combination.

10,000 scenarios · one click
03
Count where they land

Most results cluster in the middle. The budget line shows your chance.

42.8% land above forecast

The same method banks and insurers have used for decades to price risk — here it runs on your own workbook, in plain language, in seconds.

Scenario management

Every version, every assumption, in one place

Version history

Each uploaded workbook remains available as its own scenario. Open, rerun or download it later; the source file is not overwritten.

Shared assumptions

Drivers, ranges and correlations stay together in the workbook, so reviewers can see the assumptions behind every run.

Projects

Multiple projects can be easily managed.

See it with your own numbers

Start with the Excel template. Add your drivers, ranges and correlations, then run the scenarios.
