Financial Model

Also called Financial Projections

A spreadsheet that projects a company's future revenue, costs, cash, and headcount based on assumptions about growth and spending. The map of where the business is headed.

Why it matters

A model forces you to make your assumptions explicit and stress-test them, which is where the real thinking happens, more than the forecast itself. Investors expect one, and building it teaches you your own business.

For example

A founder builds a spreadsheet projecting headcount, revenue, and burn for 24 months, and stress-tests it by halving the growth assumption to see when cash runs out.
