A budget is an important planning tool that helps businesses and individuals balance their income and expenses. For a business, creating and following a budget allows it to achieve its objectives and overcome obstacles while making a profit. An individual budget helps manage finances and avoid financial problems. To create an effective budget, one must understand fixed costs that cannot change, variable costs that depend on production and sales, and the break-even point where total costs equal total revenue. Monitoring the budget monthly ensures expenses stay aligned with current statistics.
