Budget Definition and Scope

Summary

A budget is a structured plan for a defined period, commonly a month or year, that estimates expected income, expenditures, resource requirements, assets, liabilities, cash flows, and sometimes environmental or operational impacts. It converts strategic objectives into measurable financial and operational targets, helping organizations, governments, businesses, and households establish priorities, allocate resources, and assess performance. A budget may produce a surplus when income exceeds expenses or a deficit when expenses exceed available income. The scope of budgeting varies by context. Government budgets summarize anticipated revenues and spending and may include operating, capital, and cash-flow budgets. Corporate budgets forecast revenues and expenses across departments, investments, staffing, and operations, while personal budgets allocate income among living expenses, savings, debt repayment, and asset management. Budgets can also focus on specific activities, such as sales, production, projects, marketing, revenue, expenditures, or cash flow, and may use approaches such as incremental, performance-based, conditional, or zero-based budgeting.
