Financial modeling

Definition

Financial modeling is the process of creating a mathematical representation of a financial situation or scenario, often using quantitative techniques to forecast future performance. It allows analysts to simulate different financial scenarios, making it a crucial tool for decision-making in finance, investment, and risk management. By utilizing various mathematical and statistical methods, financial modeling helps assess the impact of changing variables on financial outcomes.
