A master budget is the comprehensive financial plan that consolidates all departmental and functional budgets into an integrated company-wide plan. It includes the operating budget (revenue, expenses), capital budget (CapEx), and financial budget (cash flow, balance sheet), providing the complete financial roadmap for the planning period.
In Depth
The master budget is the grand consolidation of all budgeting activities into a single, coherent financial plan. It represents the culmination of weeks or months of planning work and serves as the approved financial roadmap for the coming year.
A master budget typically contains several components. The sales/revenue budget drives everything else. The production or service delivery budget determines direct costs. Departmental expense budgets cover operating costs. The headcount budget details staffing plans. The capital expenditure budget covers asset investments. The cash budget projects cash inflows and outflows. Together, these produce a projected P&L, balance sheet, and cash flow statement.
The FP&A team orchestrates the master budget process, which typically follows this sequence: leadership sets strategic objectives and high-level targets, department heads develop their individual budgets, FP&A consolidates departmental budgets, gaps between bottom-up totals and top-down targets are negotiated, the CFO and CEO review and challenge, the board approves the final plan.
For UK businesses, the master budget should align with the fiscal year, incorporate UK-specific assumptions (tax rates, NI thresholds, pension rates), and include sufficient detail for statutory reporting while maintaining a structure that supports management decision-making.
Real-World Example
A UK group FP&A team coordinates the master budget for a company with four divisions. Each division submits revenue, headcount, and OpEx budgets. The central FP&A team adds group-level costs (head office, shared services), the capital budget (approved by the CFO), and the financing plan (debt facilities, interest costs). The consolidated master budget shows £45M revenue, £38M costs, £7M EBITDA, and a cash balance that remains above the £2M minimum covenant at all times.
