Understanding Financial Modeling: A Comprehensive Guide
Introduction
A financial model is a quantitative representation of a company's or asset's performance over a certain period of time. It is used to forecast and analyze potential opportunities and risks, and assists with strategic decision-making. There are several different types of financial models that can be used to make predictions or illustrate the dynamics of financial processes.
Definition of a Financial Model
Financial models are constructed from a combination of assumptions, focused research, and objective data. These assumptions must be based on logical foundations and accurately reflect the expected workflows and activities within a business. Financial models are used to forecast profit, revenue, and cash flows over a specific timeframe, which can be used to make important decisions regarding investments and operations.
Types of Financial Models
Financial models can be divided into two main categories: static models and dynamic models. Static models, such as the discounted cash flow model and the intrinsic valuation model, are relatively simple and are used to assess the value of an entity based on a limited set of assumptions. Dynamic models, such as Monte Carlo simulation and scenario analysis models, are more complex and account for uncertainty and changing conditions.
- Discounted cash flow model
- Intrinsic valuation model
- Monte Carlo simulation
- Scenario analysis models
Building Financial Models
Building a financial model is an analytical exercise, designed to replicate key elements of a business in which future course of action can be evaluated and decisions made. When building a financial model, you must develop an understanding of the drivers of financial information, and then pull together the necessary data, assumptions and analyses necessary to build a reliable model.
Develop an understanding of the drivers of financial information
The starting point when building any financial model is to develop an understanding of the drivers of the business. Firm comprehension of the relevant drivers will help to inform decisions made while modelling, such as which data and assumptions to use, and the structure of the model. While different models will have different drivers, the primary focus should be on understanding how changes in the input variables affect the output.
Gather data and create assumptions
Once an understanding of the key drivers is developed, the next step is gathering the relevant data needed to build the model. Depending on the complexity of the model, data can come from several sources, ranging from internal financial records, industry statistics and research, and associated third-party financial models. After gathering the data, the next step is creating assumptions to be used when building the model. Assumptions are created by analyzing the data and creating forecasts for future performance that are appropriate for the business.
Construct spreadsheets and build the model framework
Spreadsheets are used to build the financial model. Spreadsheets enable a user to demonstrate a financial model by providing a user with tools to input data and then manipulate it. Spreadsheet cells can be formatted to facilitate readability and understanding, and to prevent errors. Once the spreadsheet is set up, the model framework can begin. This includes setting up the formula structure, making assumptions and linking the model together with the calculations, as well as inputting the data.
Evaluate assumptions and outputs
The last step in building a financial model is to evaluate the assumptions used and the outputs generated. The evaluation process should focus on two key aspects: accuracy and variability. Accuracy relates to how precise the results of the model are. Variability refers to how the data and assumptions can be changed to evaluate any change in the company’s performance.
Understanding Results
Once the financial model has been created, the results will be the foundation from which business strategy is determined. It is important to understand the outputs of the financial model, how they are used as well as ways to identify any potential sensitivities in the results.
Outputs of a Financial Model
The outputs of a financial model are usually displayed in a spreadsheet, tables and graphs. Business owners as well as investors use this information to make decisions in relation to the potential success of the business. The outputs of a financial model typically include cash flow statements, profit and loss statements, forecasts and valuation calculations.
Strategic Use of Results
The results of a financial model are used to inform decisions related to the future strategic direction of the business. For example, if the cash flow projections suggest that the business will be tight on cash, management may choose to delay an investment program or delay making dividends payments to shareholders.
Sensitivity Analysis
Sensitivity analysis is a tool used to understand how changes in key assumptions may affect the results of the financial model. This type of analysis is used to understand the impact of strength or weaknesses in the business, such as changes in the price of the product, or changes in the number of customers.
Sensitivity analysis can provide valuable insights into the financial model which can then be used to inform strategic decisions. For example, if a business were considering a large capital expenditure, a sensitivity analysis could be used to determine at what point the expenditure generates a positive return.
Analysis Cycles
Financial modeling involves the formation of a set of assumptions about the project, company, industry, and economic environments to predict financial performance for decision making. It is composed of various analysis cycles. Those analysis cycles are:
- Strategic Analysis which involves the analysis of market conditions, competitor trends, product trends and customer behavior.
- Economic Analysis which involves the analysis of macroeconomics – economic indicators, government policy, competition and pricing.
- Functional Analysis which involves the analysis of operations like budgeting, forecasting, product costing and capital investments.
- Financial Analysis which involves the analysis of financial indicators, company results, and financial projections.
Models Composition
Financial modeling also consists of models composition which includes:
- Financial Statement Analysis which involves the analysis of the income statement, balance sheet and cash flow statement.
- Financial Performance Analysis which involves the analysis of key financial performance indicators, such as net income, return on invested capital, and economic value added.
- Financial Forecasting which involves the forecasting of sales, costs, profits, and other financial metrics.
- Financial Modeling & Valuation which involves the analysis of a company's financial performance and valuation of the company based on financial metrics.
Database Tables
Financial modeling is usually done using spreadsheet applications. It is often used to build database tables. These database tables store information related to the model such as transactions, transactions details, financial transactions, financial accounts, valuation metrics, financial ratios, and other related parameters. The database tables are usually built using spreadsheets applications, such as Excel or Google Sheets.
Troubleshooting Financial Models
Investing or lending in capital markets poses a great deal of risk. When it comes to assessing the financial health of an entity, being able to accurately interpret numbers and figures is in a financial analyst's best interest. Financial models are often used to simulate different financial scenarios and to predict their outcomes. As such, double-checking and troubleshooting the financial model is key in ensuring the accuracy of the findings.
Identify Errors
Errors in financial models can stem from four primary sources: errors in formulas, errors in assumptions, errors in parenthesis, and errors in logic. To help financial analysts identify these, most software programs have a built-in formula debugging tool that can run through the model and highlight potential errors. It is important to double-check each input and verify that the output is accurate.
Verify Output is Accurate
Financial models are only as good as their output, so verifying that the output is accurate is an essential step before the model is actually implemented. To ensure accuracy, it is important to get familiar with the underlying assumptions and logic of the model. Understanding the source of the output helps financial analysts to better interpret the findings. In addition, a good practice is to compare outputs to similar financial models or previously generated outputs.
Document Processes
Documenting the processes performed in a financial model can seem tedious, but it is essential in ensuring the accuracy of the model. Writing down every step taken in the model can be time-consuming, but it helps financial analysts to double-check their work and troubleshoot any errors that were not revealed in the debugging tool. Taking the time to document financial models also helps other financial analysts familiarize themselves with the model faster.
Financial modeling is an invaluable tool for financial and market analysis. However, it is important to understand that not all models are created equal. Therefore, it is key for financial analysts to take the extra time to troubleshoot and verify their models to ensure accuracy and reliability of the results.
Benefits of Using Financial Models
Using financial models is an efficient tool to analyze financial data and convey the information quickly to stakeholders. With this type of model, businesses can make informed decisions, monitor the effects of various projects, and devise strategies for improvement.
Communicate Information Quickly and Effectively
Financial models are the perfect way for financial officers and senior management to analyze and discuss organizational financials. By building a financial model, the data is easily visible and changes can be made to different parameters all from the same worksheet. As a result, time and effort is saved searching for various documents in different places. The financial model can also be shared with stakeholders, saving time and money.
Assist with Decision Making
Financial models can help businesses make decisions by offering a clear view of their financials. With the use of a financial model, businesses can assess a variety of scenarios to determine which route is the most beneficial financially and will provide the most value to the organization. Having all the data in a single format makes it easier to compare and analyze the results.
Monitor Financial Effects of Projects
When starting and running projects, businesses must continuously monitor costs and profits of their initiatives. With a financial model, all the data connected to a project can be combined into one spreadsheet and changes to variable can be monitored for profitability, cash flow, and ROI impacts. Financial models can also be used to track changes in economic conditions and market trends and help organizations identify valuable opportunities.
