Master budget

A master budget is the complete, integrated set of budgets that expresses a company's annual business plan in financial terms. It ties together every functional area — sales, production, purchasing, staffing, capital spending, and cash management — so the whole organization works toward the same targets.

The master budget has two major sections. The operating budgets begin with the sales budget, which drives everything else: the production budget follows from expected sales and desired inventory levels, and it in turn drives the direct materials, direct labor, and manufacturing overhead budgets, along with selling and administrative expense budgets. The financial budgets include the cash budget, the capital expenditure budget, and the budgeted (pro forma) income statement and balance sheet that summarize the expected results.

Because the sales forecast sits at the top of the chain, its accuracy determines the reliability of the entire plan. A well-built master budget forces departments to coordinate — production cannot plan output without the sales estimate, and treasury cannot plan borrowing without the cash budget. It then becomes the benchmark against which actual results are compared, feeding variance analysis and performance management throughout the year.

The CMA Part 1 exam tests the master budget within its planning, budgeting, and forecasting section. Know the correct preparation sequence (sales budget first), which budgets are operating versus financial, and how the pieces roll up into budgeted financial statements that later anchor variance calculations.
