The use of the Excel package in doing accounting tasks is paramount today as most small and medium businesses cannot afford to purchase accounting software packages. As a result, they do deploy the use of the Excel package in maintaining their financial data. Financial modelling is the task of building an abstract representation of a real-world financial situation. This is a mathematical model designed to represent the performance of a financial asset or portfolio of a business, a project, or any other investment. This can help them learn the skills and abilities that will help them do their jobs more efficiently and effectively. The purpose of this course is to introduce students to the many types of decision models used for decision-making and financial analysis by people inside and outside of companies. The course will guide students on how to create a summary of a company's expenses and earnings in the form of a spreadsheet that can be used to calculate the impact of a future event or decision.
