A budget is a summary of expected income and expenditure. It is a financial plan that outlines how much money an individual or organization expects to earn and spend over a given period, typically one year. A budget can be used by individuals, businesses, and governments to manage their finances, make informed financial decisions, and ensure that they are living within their means. The budget will show the expected income, such as salaries or revenues, and the expected expenses, such as rent, utilities, and other bills. By comparing the income and expenses, individuals and organizations can identify areas where they may need to reduce spending or increase income to balance the budget.
