A budget is the government's annual financial plan that estimates expected revenue and expenditure for a fiscal year. It is one of the most important tools of public finance because it helps allocate resources, promote economic growth, reduce inequality, and maintain fiscal discipline. Budgets are classified into different types based on their financial position, purpose, and presentation, such as balanced, surplus, deficit, revenue, capital, productive, unproductive, open, and closed budgets. Understanding these concepts is essential for students preparing for banking, Loksewa, and other competitive examinations, as questions on budget and its types frequently appear in objective tests.
