Power BI for Financial Modelling: A Modern Approach to Financial Analysis
Introduction to Power BI
Financial modelling continues to be a core competency for success in finance; it gives people, companies, and investors insight into their performance, how they can expect to perform in the future, and how they can make better decisions based on robust measurement or information. Historically, financial models were heavily created using Excel sheets; however, while Excel is still a great product, it has its share of shortcomings when companies begin managing ever-increasing levels of complex and large datasets.
When businesses expand, they generate unprecedented amounts of information due to sales, cost of goods sold, advertising, and marketing activity, production and operational support, human resources, and many other categories of business activity. Attempting to manage all of this financial information within a single model or worksheet will likely be both very time consuming, require many additional changes within the model, and introduce significant potential for errors within the model. Through its many advantages over Excel, Power BI can assist financial analysts with creating financial models faster, accurately, efficiently, and in a visually stimulating way.
Microsoft Power BI is a data visualization tool that allows users to acquire, sort, filter, analyze, and visualize multiple records using multiple metrics in a single dashboard. The best way to think of Power BI is as a more user-friendly and intelligent version of Excel. With the ability to load large volumes of data into the application and generate dashboards almost immediately, Power BI simplifies the participant’s view of financial performance versus Excel, which requires opening many sheets and running dozens of calculations.
Power BI can pull data from an endless number of sources (e.g., Excel, the Internet, databases, etc.) and automatically updates itself once set up; therefore, the user can obtain a complete financial model on an ongoing basis without requiring constant checking and updating to ensure accuracy.
Why Power BI Is Becoming Important in Financial Modelling?
Power BI is emerging as a crucial tool in developing financial models because it provides numerous solutions to issues commonly faced by finance professionals. In Excel, data is collected manually, cleaned manually, and data must be imported every month by either copy/paste or uploading files. By contrast, with Power BI, this entire process is automated once the connection to the source of the data is made. By simply clicking on update in Power BI, all of the data connected to the source of the data will be updated automatically.
Furthermore, Power BI allows users to process larger data sets than Excel can. In fact, Excel will slow down or even crash if too much data has been entered at once. With Power BI, you can work with millions of records simultaneously without a noticeable difference in speed, and this ability is vital for organizations that have decades worth of historical data or thousands of transactions.
How Power BI Improves Financial Analysis?
Power BI provides many tools to allow business analysts and accountants to develop more effective calculations and gather insights. Using DAX, a formula language that is similar to Excel, but with more power and flexibility, allows you to define the performance of your business in terms of actual numbers.
-
You can create measures like revenue growth, net profit, operating margin, gross margin, EBITDA, and return on investment.
-
These metrics are automatically calculated across your entire report/dashboards. By using that method, you avoid the need to make changes in multiple cells and potentially duplicate errors.
-
Instead of having to edit multiple cells, one DAX measure will update every location where that measure is referenced.
Power BI enhances your financial analysis by enabling you to examine your business's performance in real-time. You do not have to wait until the end of the month or wait on printed reports to see what the most recent situation is. Additionally, you can have your financial model update daily, weekly, or automatically, based on your configuration settings. Having the most up-to-date numbers at your fingertips is invaluable to business planners and budgeters when it comes to planning, budgeting, and forecasting.
Steps Involved in Using Power BI for Financial Modelling
The first step when creating a financial model using Power BI is to gather and bring in financial data. This could mean exporting information from very many different places including accounting packages, ERP systems, Excel sheets, CSV files, Sales databases, or Payroll systems to include into Power BI. Once you have added all of your data into Power BI, the next step is to clean it and prepare it for modelling. This process is often referred to as “cleaning” the data because the data you have collected may include many errors including missing values, incorrect formats, duplicates, or inconsistent categories.
-
Power Query, a tool within Power BI, allows for fast data preparation for financial modelling. Instead of taking time to correct each individual record in the data set, you can prepare the data using Power Query’s transformation feature and save that format. Whenever you bring in new financial data, Power Query records your formatting steps, and it automatically formats each newly imported file using your formatting steps for consistency and time-saving.
-
The next process after preparing your financial data will be developing relationships between all of your different tables. When creating a financial model, it is not uncommon to include various tables containing sales, expenses, product, customer, and general ledger account data from different systems. Linking those tables to create relationships using formulas in Excel can be somewhat cumbersome.
-
There is an easy-to-understand model of Data Modelling in Power BI providing users with a simple drag-and-drop interface for connecting different tables by dragging and dropping fields. With this user-friendly methodology, you will be able to build a well structured and well-organised data model that forms the basis of a well-functioning and effective Financial Model.
When the Data Model is complete, it's time to apply DAX (Data Analysis Expressions) formulas for creating Financial calculations which will convert your raw data into useful information that can be used for Financial Decision Making. Once you have created the Financial Calculations, you will move on to creating your Dashboards; Dashboards in Power BI consist of Revenue Charts, Profit Margin Charts, Cost Breakdown Charts, Cash Flow Charts, and many more.
Essentially, Dashboards in Power BI combine all of the important charts necessary to have a complete view of the Financial Model. Dashboards in Power BI differ from Excel in that they are Interactive; therefore, Users may access the charts for exploration, exploration, analysis and creating reports.
Types of Financial Models You Can Build in Power BI
With the assistance of Power BI, organizations have the ability to create a myriad of different forms of financial model, including a revenue model, which will allow businesses to analyze their revenue by several different dimensions, such as by product, by region and by type of customer, over a period of time. Revenue analysis can assist organizations with identifying both the growing and declining areas of revenue. The Power BI Cost Model allows for visibility into costs at the fixed/variable expense level, and by the department and by the month. This model will aid in managing the overall cost of your organization, while providing insight into potential efficiencies that exist within your organization.
Ratios produced using Financial Ratios Models found in Power BI include Liquidity Ratios, Profitability Ratios, Leverage Ratios and Efficiency Ratios, which allows for Analysts and Investors to more easily evaluate a company's overall Health. In addition to Historical Data, Power BI can provide Estimated Future Performance utilizing Forecasting Models based on both Historical Data and Assumptions about Future Performance.
Benefits of Using Power BI for Finance Teams
Finance teams experience significant benefits from the use of Power BI, as Power BI streamlines time-consuming tasks, reduces mistakes and allows greater collaboration. With Power BI automating repetitive activities (e.g., that of collecting, cleaning, and updating data), finance professionals have more opportunity to spend their time performing analyses and making decisions.
Since the cleaning steps and formulas are set up to run automatically via Power BI, errors are greatly minimized and therefore financial models are much more reliable than using Excel. Further, Power BI allows teams to easily share dashboards with managers and co-workers through the Power BI Service which, when accessed via a laptop, tablet, or cell phone, allows for more flexibility in access to shared dashboard information.
In addition, financial presentations are now much more professional with the development of dashboards via Power BI since the final result is a very modern and clean looking product that provides interactivity. Decision makers prefer visual dashboards to lengthy, hard to read PDF or Excel reports, thus, this simplifies and enhances the communication experience within the organisation and further assists in developing a data-driven organisational culture.
Future of Power BI in Financial Modelling
As financial modelling shifts towards being more data driven, the increased use of Power BI is anticipated to support this future trend. Companies have access to more data than ever and therefore require a combination of new technologies including those capable of handling large amounts of data, automating time-consuming tasks, and presenting information effectively.
The ability of Power BI to connect effortlessly with Excel spreadsheets, Microsoft SQL Server, Cloud computing platforms, and other types of enterprise applications makes it an excellent choice for finance teams in the modern workplace. Many companies are beginning to create job descriptions which include a requirement for Finance professionals to be proficient in Power BI as it increases their ability to make intelligent and rapid financial decisions through improved efficiencies.
Conclusion
Modern financial modeling has undergone a major transformation thanks to Power BI. Previously, the majority of a finance team's efforts were dedicated to gathering the necessary data, correcting errors, updating formulas, and generating static reports. Now, Power BI automates nearly all of the tedious steps and allows finance professionals to concentrate on developing analysis, producing valuable insights, and making informed decisions. Power BI connects with numerous data sources and allows data to be refreshed automatically, in addition to managing large amounts of data.
