When deciding the optimal trade-off between desired level of detail and model reusability i. At this juncture, we are ready to open Excel and to begin thinking about structuring. The better one is at segregating these sections, the easier it will be to audit and amend the model while minimizing errors and optimizing on time. I have followed the same structural approach for almost every model that I have built; an approach which both my respective stakeholders and I have always found practical, digestible, and ultimately useful.

Its sections are as follows:. The cover page is the first point of contact with your work. While it is the simplest to build, when done well, it leaves a great first impression and clearly explain what is to come. A simple, instructional cover page is generally the best approach and typically includes the following sections:. Please note: I recommend that the cover page always be locked to anyone and everyone without express authority to make changes, outside the author.
You must ensure that this tab is clear, concise, and easy to understand, as this is the tab that non-finance operators will likely manipulate most often. I usually recommend implementing two input sections within the inputs tab, one for static inputs and the other for dynamic. Within both of the above static vs. Note, however, that you never fully know which parameters are going to constitute sensitivity parameters and which you will not until the final stages of the project.
For more on sensitivity modeling, please refer to the following article. It is also out of this tab that various assumption-driven scenarios will be run as well as the valuation piece of the exercise that will be conducted ahead of the final strategic decision. Authorized, third-party model operators will use the Scenarios and Sensitivities tab fairly often, even if just to select their choice of pre-programmed scenarios.
For this reason, you should build scenarios intuitively, protect the actual scenarios from outside editing, and build sufficiently varied sensitivities such that the handful of pre-programmed scenarios will be sufficient to yield a wide view of possible outcomes once sensitivity tables sample below are also built.

For your consideration, the scenarios format structure I have relied on throughout my career is as follows, as just one type of example:. The output tabs are the tabs that operators of the model will use most frequently.
At this juncture, the construction phase of the model is officially complete. We may turn our attention to some of the expert-level modeling best practices I referred to at the onset of the article.

As such, while building, it is important to first check in with—and adhere to—whatever format your respective firm prescribes. The first and lowest-hanging formatting method for financial modeling is to use consistent and identifiable color schemes to denote different types of cells and data. As follows:.

Please note that there is no in-built automation functionality to color code your Excel spreadsheets according to the universal color coding standards above. Instead, you may design your own macro s to achieve these outcomes, and subsequently create shortcut combinations to automatically color-code your work. Sometime in my recent past, I received from a colleague who I thank to this day , the following macros including detailed instructions , which have since saved me several hours of manual labor. Finding links to other workbooks and worksheets is tricky, and you will most likely have to use VBA to get this working correctly.
Fortunately, green cells are rarer than black or blue cells, so the method above works fairly well in most models and you can organically format the rest of your links to other worksheets manually as they come up or as you come across them. Such hacks and tricks, however clever they may seem at the time, and especially after time intervals, will invariably be forgotten and will lead to hard-to-track-down errors. Keeping a third-person reviewer in mind will guide you through your process and help you come to the right decision at key junctures.

Back to top. I have discussed the pros and cons as well as some alternatives in an earlier article.
However, by following a set of proven best practices, you can minimize these downsides and significantly increase the credibility of your model. I will start with a brief discussion on the nature and characteristics of financial models for better understanding. Like all other models, a financial model is a simplified image of reality. It is an abstraction that reduces to complexity of real-world financial flows to a degree that allows meaningful calculations.
This abstraction describes an operational system with regard to its financial flows cash and — if necessary — other relevant economic flows e. This takes place on two levels:. The model determines the internal structure and the relationships between the components to be calculated e. These are the functions and formulas.
