The main purpose of a budget is to plan and manage financial resources effectively. It helps individuals, families, businesses, and governments outline their income and expenditures over a specific time frame, allowing for informed decision-making. By establishing a budget, one can track spending habits, prioritize expenditures, and set financial goals, such as saving for a major purchase or paying off debt. A well-structured budget also encourages accountability and financial discipline, helping to prevent overspending and align financial practices with overall objectives. Regularly reviewing and adjusting a budget is key to maintaining financial health and stability.
