Capital budgeting is a critical process for evaluating long-term investments in assets like property and equipment. It helps companies allocate resources to projects that maximize shareholder value by assessing viability, profitability, and factors such as initial costs and expected cash inflows. This process plays a crucial role in a company's growth and competitiveness. It involves using various decision-making tools like Net Present Value and Internal Rate of Return to analyze potential investments, considering risks, cash flows, and real-world applications in areas such as capacity expansion and new product development.
