A master budget is the single consolidated financial plan for a coming period, assembled by combining an organization’s separate budgets into one coordinated set of budgeted financial statements. It holds the operating budgets, which plan revenue and the spending required to earn it and end in a budgeted income statement; the capital expenditure budget, which plans spending on long-lived assets; and the financial budgets, which plan cash and end in a budgeted balance sheet. What makes it a master budget rather than a stack of budgets is the sequence: each piece supplies an input the next one needs, so the sales budget is built first and cash falls out last.
What a Master Budget Contains
The operating budgets plan the day-to-day business. They are the sales budget, the production budget, the direct materials budget, the direct labor budget, the manufacturing overhead budget and the selling and administrative expense budget, and once all of them exist their costs are used to prepare a budgeted income statement (OpenStax, Principles of Accounting, Volume 2: Managerial Accounting, Prepare Operating Budgets).
The financial budgets plan the money and the closing position. Preparing them requires the capital asset budget, the cash budget and the budgeted balance sheet, and the capital asset budget is also called the capital expenditure budget (OpenStax, Prepare Financial Budgets).
Treatments differ only on where the capital expenditure budget is filed. One common presentation gives the master budget two major categories, operating and financial, with the financial half planning the use of assets and liabilities and resulting in a projected balance sheet (OpenStax, Describe How and Why Managers Use Budgets). Another counts three, pulling the capital expenditure budget out on its own. The content is identical either way, so the count is a labeling choice and not a difference in what gets built.
The Order a Master Budget Is Built In
The sales budget is built first and the budgeted balance sheet is built last. Every step between them is fixed by what it needs as an input, which is why the order is part of the definition rather than a matter of preference.
Sales comes first because the units expected to sell decide two separate things downstream: how many units have to be made, and when and how much cash arrives from those sales.
The production budget follows. Units to produce equals budgeted unit sales plus the desired ending inventory, less the units already sitting in beginning inventory, which is the cost of goods sold formula run in reverse. A merchandiser has no production step, so a merchandise purchases budget takes its place and plans units bought instead of units made.
Three budgets then hang off that production figure. The direct materials budget turns units to produce into the quantity of raw materials to order and what that material costs. The direct labor budget turns the same units into labor hours and multiplies those hours by a labor rate. The manufacturing overhead budget covers the remaining production cost, treating the variable component as moving with budgeted activity and the fixed component as staying flat, and the rate that comes out of it is the subject of predetermined overhead.
The selling and administrative expense budget sits outside that chain, because those costs are not product costs. It lists the variable and fixed expenses estimated for every area other than production, and its variable part moves with budgeted sales rather than with units produced, so it is built off the sales budget instead of the production budget.
Together the operating budgets produce the budgeted income statement, with the manufacturing costs split between cost of goods sold and ending inventory and the period costs expensed in full.
The capital asset budget is prepared before the cash budget rather than after it. A planned purchase of long-lived assets is a large cash commitment that the cash budget has to carry, and if the cash will not be there, the capital plan is what gets adjusted and carried back in.
Cash is settled last, and two schedules feed it. The cash collections schedule runs off the sales budget, applying the pattern by which customers actually pay and leaving out the portion estimated as uncollectible. The cash payments schedule runs off the direct materials budget, applying the terms on which the entity pays for what it bought. The cash budget then combines both with the direct labor budget, the manufacturing overhead budget, the selling and administrative budget and the capital asset budget, less any non-cash item such as depreciation.
The budgeted balance sheet closes the set, because the opening and closing cash balances, the financing drawn and the changes in equity are all outputs of everything above it.
The Calculation the Sequence Turns On
Say a manufacturer runs a target ending inventory policy set as a share of the following quarter’s sales, and the first quarter of the plan carries the figures below.
Budgeted unit sales, quarter 1 1,200 units
Budgeted unit sales, quarter 2 1,000 units
Desired ending inventory 30% of Q2 sales = 300 units
Units required 1,200 + 300 = 1,500 units
Beginning inventory on hand 200 units
Units to produce 1,500 - 200 = 1,300 unitsEvery budget downstream of that last figure is built on it, so the ending inventory policy moves the materials order, the labor hours, the overhead applied and the cash paid to suppliers all at once. That is why the policy is settled before the chain is run rather than during it.
Where a CPA Firm Meets a Master Budget
A US accounting firm meets the master budget on the client advisory side rather than in tax or attest work. The engagement-level version on the firm’s own book, budgeted hours and budgeted fees on a job, is a different instrument and belongs to budgeted.
On client work the job is assembly and revision rather than authorship. The operating assumptions come from the client’s own managers, the chain gets run in the order above, and the pieces that moved get rebuilt once the period’s actuals settle on the month-end close calendar. Revision is what keeps the plan worth measuring against, and the planning-then-control loop it sits inside, including who approves the plan and what changes when an outside funder does, is set out in budgetary planning.
What a Master Budget Is Confused With
A Flexible Budget
A master budget is a static budget, built at one planned volume. Compared straight against actual results it shows that the volume differed, but not whether the costs were appropriate for the volume actually reached, which is what expenses evaluated on a flexible budget computed for the units actually sold do show (OpenStax, Explain How Budgets Are Used to Evaluate Goals). A flexible budget is the same plan restated at the volume reached, and it exists to separate a spending effect from a volume effect. Splitting an absorbed factory overhead gap along exactly that line belongs to 2-way variance analysis, and isolating the price half of a material gap belongs to purchase price variance.
A Forecast or a Standard Cost
A master budget is an approved plan for a period. It is not a prediction of what the responsible party expects to happen, and it is not a set of per-unit standards. Both separations are worked through in budgeted.
The Individual Budgets Inside It
A sales budget or a cash budget is a component, not a master budget. What makes the set master is the assembly plus the order tying the components together, so a cash budget produced alone, without the sales and materials budgets feeding it, is a cash projection rather than part of a plan.
What Is the Primary Purpose of a Master Budget?
The purpose is to commit the entity to one internally consistent plan and to give the period something to be measured against. Because every component is built from the same sales assumption, the set also shows what that single assumption does to cash and to the closing balance sheet before the period starts, which is a question no individual budget can answer on its own.
Accountably places trained offshore accountants inside US CPA and EA firms, and a firm can put a real block of its own close and budget-to-actual reporting through a trial task before anything client facing depends on it.
