What is financial modeling?
Financial modeling is creating a complete program/ structure, which helps you in coming to a decision regarding investment in a project/ company. Now this could be on a simple piece of paper or in excel. The advantage with excel is that, even if you have calculation speed and accuracy like me (this is one place where I am like Einstien!), then also you would be able to come to the right conclusion!
Who does Financial Modeling?
Anybody dealing with any decision related to money (wish there was somebody who did not require that!). If you are involved in financial decision making/ planning related to large corporate, then you would definitely need financial modelling day in and day out. Financial modeling is a mandatory activity for investment bankers, bankers, project finance persons, equity research folks, PE & VCs.
What are the steps in building a financial model?
•Data collection – This is where the real front end banker works. She goes to the client, collects the data like revenue, growth, investments, need for money, etc.
•Back of the envelope calculations – Now most of the corporate guys are very hunky dory about their business. They usually think that their idea is one of a kind and is going to generate loads of mullah. Banker would sanitize their thoughts and try to figure out, if the business makes sense. Initially the thinking and analysis is very simple,
o Does the corporate guy look sober to me?
o How soon can I get my investment back?
o Is the revenue that he is projecting seem greater than the market size?
You usually need no industry knowledge for this. Just keep your eyes and ears open and put your thinking cap on!
•Structured approach to thinking – Once the basic numbers seem reasonable (they make business sense and seem to be true as well), you have to dig deeper! This is where you need a complete financial model. And the first real step to doing that is to think of a structure of analysis. Thankfully finance has some basic theories in place and you can rely on them to proceed:
o Cash is the king – The more cash is generated (from the operations of the business) the better is the business
o Money today is better than money tomorrow – technically this can be called Time value of money. But it does not matter!
Practically these are the fundamental building blocks of analysis and you have to start thinking in these terms for the analysis
•Deciding on a Layout – Now when you start to put this plan in excel, the starting point is deciding on a layout for your financial model. Usually the following questions need to be answered:
oHow much information/ data would your model have? If its going to be large, then it might make sense to break the model in multiple sheets
oWhat kind of assumptions would your model make? For better readability, we would try to keep assumptions in a different heading than the calculations and the final conclusion
oDifferent fonts/ formatting for assumptions and other parts might enhance readability as well
o Create logical modules for your model
Keep your P&L, Balance Sheet, cash flow statement, etc. separate
Even in P&L, keep the revenue generation separate from costs
