Budget: Comprehensive Guide

A detailed examination of budgets, including definitions, historical context, types, and their significance in both organizational and governmental contexts.

Definition

  1. A financial or quantitative statement, prepared prior to a specified accounting period, containing the plans and policies to be pursued during that period. It is used as the basis for budgetary control. Generally, a functional budget is drawn up for each functional area within an organization, but in addition, it is also usual to produce a capital budget, a cash-flow budget, stock budgets, and a master budget which includes a budgeted profit and loss account and balance sheet.
  2. In the UK, the government’s annual budget is presented to parliament by the Chancellor of the Exchequer. It contains estimates for the government’s income and expenditure, together with the tax rates and the fiscal policies designed to meet the government’s financial goals for the succeeding fiscal year.

The fuller “Understanding Budgets” article covered the same concept with more explanation and examples, so this canonical page now includes both treatments in one place.

Zero-Based Budgeting

Zero-based budgeting starts each budget cycle from a zero base and requires every expense to be justified again. The older zero-base budget explainer used the same underlying concept, so the budgeting page now carries that material directly instead of splitting it into a separate definition entry.

Types/Categories of Budgets

  • Operational Budgets: These cover the income and expenses associated with the day-to-day functions of an organization.
  • Capital Budgets: Plan for investments in long-term assets like machinery, buildings, etc.
  • Cash-Flow Budgets: Predict the cash inflows and outflows over a particular period.
  • Master Budgets: Consolidate all individual budgets, reflecting an organization’s overall financial plan, including budgeted profit and loss account and balance sheet.
  • Stock Budgets: Address inventory management and costs associated with maintaining stock levels.

Budgetary Control

Budgetary control involves the use of budgets to monitor and control income and expenditures within an organization. This is critical for achieving financial objectives and ensuring efficient resource utilization.

Why Budgets Matter

  • they help compare actual results against expectations
