Overview of Financial Modeling

Financial modeling is the process of creating a projection of a company’s future financial performance. This projection is usually represented in a spreadsheet format and contains the assumptions the modeler has made to derive their financial outcomes. Financial modeling is typically used to assess the potential success of a business venture or project and can be used to advise decisions such as whether or not it is worth investing in, or if the process requires outside financing.

What is Financial Modeling

Financial modeling is the process of using past financial performance to predict a company’s future financial performance. It typically consists of constructing a model of the company’s financials in the form of an Excel spreadsheet. Financial models are used for a variety of scenarios, such as assessing the potential success of a business venture or project. It can also be used to advise decisions such as whether or not it is worth investing in, or if the process requires outside financing.

Common Components

A financial model typically consists of the following components:

  • Income Statement
  • Balance Sheet
  • Cash Flow Statement
  • Assumptions
  • Key Metrics

Examples of Outputs

The output of a financial model typically consists of the following metrics:

  • Revenue Growth
  • Net Income
  • Cash Position
  • Debt Growth
  • Capital Expenditures

Preparation for Building the Model

Creating a financial model for a start-up is no easy feat. Whether you are planning to create the model yourself or are going to hire a professional, it is important to be prepared in order to successfully build an accurate and comprehensive model. The following steps will provide guidance on how to prepare for building a financial model for a startup.

Collecting Assumptions

When creating a financial model for a startup, it is necessary to make a series of assumptions about the best-case, worst-case, and most likely scenarios for the business. The assumptions should be explained in a white paper and based on the industry, size of the potential market, and financial resources available. Additionally, assumptions should be made about the level of investment, sales strategies, and other relevant factors.

Gather Relevant Data

When preparing to create a financial model, it is important to gather data to use as input for the model. This data should provide a view of the business’s past performance, such as expenses, revenue, and cash flow. Additionally, industry trends and financial forecasts should be considered and included in the data. This data will provide information necessary to create a realistic financial model.

Understand the System and Industry

Before starting to build the financial model, it is important to understand the system and industry. This'll help create both a long-term and short-term forecast of the startup’s success. Additionally, it will provide an outline of the industry and its performance in the past which will give insights into planning the business’s future performance.

Identify Your Aim

It is essential to identify the ultimate aim before beginning to build the financial model. It is important to consider the business’s needs both in terms of short-term aims and long-term goals. Additionally, the financial model must be able to provide clear opportunities for investors and estimate performance for the foreseeable future. It is only once the aim is clearly outlined that the model can be created.

4. Using Spreadsheets for Financial Modelling

When it comes to financial modelling, spreadsheets can be a powerful tool for startups. The simplicity, flexibility, and cost-effectiveness of the software makes it a great choice to provide insight into the financial health of a company. Whether you’re a startup founder, investor, or accountant, here’s how to create a financial model using spreadsheets.

A. Structuring the Model

The first step is to decide how the model should be structured. There are several factors to consider, such as the type of financial model (e.g. discounted cash flows, Three Statement Model, etc.), the metrics that will be used to measure performance (e.g. margins, turnovers, etc.), and the frequency of the data (e.g. monthly, quarterly, etc.). The goal is to create a model that is intuitive, easy to use, and meaningful to the user.

The spreadsheet model should also have a logical structure and layout that makes it easy to follow. For example, the inputs should be at the top and the outputs at the bottom, with formulas linking them together. It's also a good idea to add comments to clearly indicate what each number represents, so it’s easy to see how changes to the inputs affect the outputs.

B. Data Entry and Formulas

Once the structure is in place, it’s time to enter the data and build the formulas. This can involve the collection and entry of historical financial data, as well as forecasting assumptions and expected outcomes. When creating the formulas, try to use fundamental principles and sound financial theory, such as the time value of money and net present value. This will increase the accuracy of the model and give the user confidence that the numbers make sense.

When entering data and building formulas, there are a few best practices to keep in mind. First, use absolute cell references when referencing values, as this ensures that the formulas are always referring to the correct cells, even if the model is expanded or modified. Second, use transparent formulas that show the calculation, instead of more obscured formulas. This makes it much easier to review, debug, and modify the model if needed.

C. Testing and Validating the Model

Once the model is built, it’s important to test and validate it. This involves reviewing the formulas to make sure that all of the cells are linking correctly, as well as testing different scenarios to ensure the model is providing accurate results. Additionally, it's a good idea to have someone with a financial background review the model, as they can Often spot potential errors or problems that may have been overlooked.

Finally, it’s a good practice to include a sensitivity analysis or stress testing in the financial model. This will help to identify potential problems and reduce the risk of surprise losses or unexpected outcomes. By testing different scenarios, startup founders and investors can be confident that the financial model is accurate and reliable.

Further Steps for Building a Financial Model

Once you have a basic idea of the financial structure of your startup, it is necessary to go further and make sure your model is robust and accurate. Taking the following steps will ensure that you have a reliable and well-constructed financial model:

Developing Forecasts

Forecasting is an important step in the creation of a financial model for your startup. Forecasting allows you to identify potential risks, make adjustments as needed, and refine your projections. When developing your forecasts, it is important to consider the following factors:

  • Market trends and outlook
  • Industry trends
  • Competitor analysis
  • Regulations and legislation
  • The state of the economy

Calculating Key Metrics

Your startup financial model should incorporate key metrics, such as revenue and expenses, profit and loss, cash flow, and net present value. These metrics will help you measure the performance of your startup, so it is important to make sure they are accurate and up to date. Make sure to include key metrics in your model and to update them on a regular basis.

Best Practices

When creating a financial model for your startup, there are some best practices to keep in mind:

  • Be conservative when making assumptions.
  • Reflect any changes in the marketplace and related developments in your model.
  • Test and refine your model regularly.
  • Reflect any external factors that could affect your startup.
  • Check the accuracy of your calculations.
  • Monitor your assumptions and forecasts to ensure they remain valid.

Analyzing the Outputs

Once you have created the financial model of a startup, it's essential to analyze and assess the outputs that the model produces. By doing so, you can gain insight into the financials of your startup, as well as any existing financial trends. To get the most out of your financial model, review the outputs produced by the model and consider the following.

Interpreting the Results

Forecasting the financials of a startup is no easy task. Throughout the process, special care must be taken to ensure accuracy and reliability. Once you have constructed the model, review the figures and ask yourself questions such as:

  • Do any figures requested by potential investors or lenders seem accurate?
  • Are there any figures that appear to be outliers?
  • Do any figures appear to be conservative or overly optimistic?
  • Are the calculations complete and accurate?

Analyzing the outputs of the model provides you the opportunity to take a step back and assess the accuracy of the model. It also allows you to identify any potential issues or errors and make the necessary adjustments to make the model more accurate.

Understanding Trends

Financial analysis of a startup doesn't end with the review of individual figures. It's also important to gain an understanding of the trends that the model produces. Consider the questions below as you analyze the trends:

  • Are there any positive or negative trends present?
  • Are there any unexpected patterns or relationships that can be seen?
  • Are there any inconsistencies over a particular period of time?

While trends can sometimes be difficult to detect, the ability to spot them can provide you with valuable insights into the overall financial state of the startup. This insight can be of great value when it comes time to make key decisions related to the future of the business.
