What Is Financial Modeling?

Financial modeling is the process of creating a summary of a company's expenses and earnings in the form of a spreadsheet that can be used to calculate the impact of a future event or decision.

A financial model has many uses for company executives. Financial analysts most often use it to analyze and anticipate how a company's stock performance might be affected by future events or executive decisions.

The Basics of Financial Modeling

Financial modeling is a representation in numbers of some or all aspects of a company's operations.

Such models are intended to be used as decision-making tools. Company executives might use them to estimate the costs and project the profits of a proposed new project. Financial analysts use them to anticipate the impact of an economic policy change or any other event on a company's stock.


Understanding Financial Models

Other Uses of Financial Models

Financial models are used to estimate the valuation of a business or to compare businesses to their peers in the industry. They also are used in strategic planning to test various scenarios, calculate the cost of new projects, decide on budgets, and allocate corporate resources.

Real World Example

The best financial models provide users with a set of basic assumptions. For example, one commonly forecasted line item is sales growth. Sales growth is recorded as the increase (or decrease) in gross in the most recent quarter compared to the previous quarter. These are the only two inputs a financial model needs to calculate sales growth.

The financial modeler creates one cell for the prior year's sales, cell A, and one cell for the current year's sales, cell B. The third cell, cell C, is used for a formula that divides the difference between cell A and B by cell A. This is the growth formula. Cell C, the formula, is hard-coded into the model. Cells A and B are input cells that can be changed by the user.

In this case, the purpose of the model is to estimate sales growth if a certain action is taken or a possible event occurs.

Of course, this is just one real-world example of financial modeling. Ultimately, a stock analyst is interested in potential growth. Any factor that affects, or might affect, that growth can be modeled.

In addition, comparisons among companies are important to making a conclusion about a stock. Multiple models help an investor decide among various competitors in an industry.
