What This Model Solves

Most business valuations give you one number. But one number hides enormous uncertainty. Is your company worth $2M or $5M? The honest answer is: it depends on assumptions — and assumptions have ranges.

This Monte Carlo valuation model makes that uncertainty visible and quantifiable. Instead of a point estimate, you get a full probability distribution: the most likely value, the downside scenario, and the upside scenario — all computed automatically across thousands of simulations.

Who This Is For

SME owners preparing for a sale, partnership negotiation, or investor conversation
CPAs and financial advisors who need a rigorous, explainable valuation tool for clients
Corporate finance analysts who want a fast, flexible scenario engine
Entrepreneurs raising capital and building investor decks

No financial modeling background required. The model includes a setup guide and every assumption is labeled and documented.
