Problem Overview

In our Excel file, we have created a financial model for an online consumer company. Using this model, we will forecast the financial position of the company for the years 2022, 2023, and 2024. We have created an income statement, a balance sheet, and a cash flow statement. Additionally, we have added the assumptions for each statement in a separate table.

Now, the most common practices for financial modeling in Excel are given below. Your task is to apply these practices in the

  • Firstly, create everything in the financial model on the same sheet.
    • This will speed up our navigation time. Additionally, this practice will reduce the risk of linking to unintended cells.
  • Secondly, use color coding.
    • You need to distinguish the hard coded values with a different font color. Blue color is widely used to denote this.
  • Thirdly, make the assumptions in a separate table.
    • There are a lot of assumptions in a financial model. If you create those in a separate space, it will be easier to change in the future.
  • Then, use different types of cell references but avoid circular references.
  • After that, make the headers and sub-sections easier to read.
    • You can make the headers and subsections bold to easily identify later.
  • Next, ensure the balance sheet balances.
    • This will make sure your model is working correctly. The formula is Asset = Liability + Owner’s Equity. You can subtract Total Assets from the Total Liabilities and Shareholders’ Equity. If the output is 0 or “$ –” incase of the accounting number format, your model is fine.

  • Lastly, it is best to denote all income as positive and all expenses as negative.
