§Financial modeling is a tool for determining likely financial outcomes based on a company’s historical performance and assumptions about future revenue, expenses and other variables. Financial modeling relies on financial forecasts: It takes a forecast’s assumptions and plays them out using a company’s financial statements to show how those statements may look in the future. Because models are created from financial statements, they most often generate results for a month, quarter or year.
§Most financial models are constructed in an Excel spreadsheet and require manual data entry. One of the simplest types, known as the three-statement model, only requires an income statement, balance sheet, cash flow statement and supporting schedules. However, the uses for models vary greatly, so some are much more complex. Businesses routinely customize models for their own purposes.
