Financial modeling is the task of building an abstract representation a model of a real world financial situation. Financial modeling is a general term that means different things to different users; the reference usually relates either to accounting and corporate finance applications, or to quantitative finance applications.

While there has been some debate in the industry as to the nature of financial modeling—whether it is a tradecraftsuch as welding, or a science —the task of financial modeling has been gaining acceptance and rigor over the years. In corporate finance and the accounting profession, financial modeling typically entails financial statement forecasting; usually the preparation of detailed company-specific models used for decision making purposes [1] and financial analysis.

To generalize [ citation needed ] as to the nature of these models: Correspondingly, both characteristics are reflected at least implicitly in the mathematical form of these models: For discussion of the issues that may arise, see below; for discussion as to more sophisticated approaches sometimes employed, see Corporate finance Quantifying uncertaintyand Financial economics Corporate finance theory. Modelers are often designated " financial analyst " and are sometimes referred to tongue in cheek as "number crunchers".

Accounting qualifications and finance certifications such as the CIIA and CFA generally do not provide direct or explicit training in modeling.

Although purpose built software does exist, the vast proportion of the market is spreadsheet -based; this is largely since the models are almost always company specific. Also, analysts will each have their own criteria and methods for financial modeling.

Spreadsheet-based modelling can have its own problems, [6] and several standardizations and " best practices " have been proposed. One critique here, is that model outputsi. What is required, but often lacking, is that all key elements are explicitly and consistently forecasted.

Additionally, for many of the standard derivative and portfolio applications, commercial software is available, and the choice as to whether the model is to be developed in-houseor whether existing products are to be deployed, will depend on the problem in question. The complexity of these models may result in incorrect pricing or hedging or both.

This Model risk is the subject of ongoing research by finance academics, and is a topic of great, and growing, interest in the risk management arena. Criticism of the discipline often preceding the financial crisis of —08 by several years emphasizes the differences between the mathematical and physical sciences, and finance, and the resultant caution to be applied by modelers, and by traders and risk managers using their models. Some go further and question whether mathematical- option pricing models and volatility using excel vba download statistical option pricing models and volatility using excel vba download may be applied to finance at all, at least with the assumptions option pricing models and volatility using excel vba download made for options ; for portfolios.
