1. Master Budget Construction Sequence
The master budget is a cohesive network of operational and financial budgets mapped out for an upcoming period. It must be prepared in a precise chronological sequence because each schedule relies on the output of the preceding one:
  1. Sales Budget (The primary driver based on demand forecasting)
        │
        ▼
  2. Production Budget (Units needed = Target Ending Inventory + Sales - Beginning Inventory)
        │
        ├───────────────────────────┼───────────────────────────┐
        ▼                           ▼                           ▼
  3a. Direct Materials Budget   3b. Direct Labor Budget   3c. Manufacturing Overhead Budget
        │                           │                           │
        └───────────────────────────┼───────────────────────────┘
                                    ▼
                        4. Ending Inventory Budget
                                    │
                                    ▼
                        5. Cash Budget (Inflows & Outflows)
                                    │
                                    ▼
                  6. Budgeted Financial Statements (Pro Forma)

2. Flexible Budgets vs. Static Budgets
  • Static (Master) Budget: Planned at the start of the year based on a single, fixed projected activity level. It is highly flawed for performance evaluation if actual sales volumes differ from original projections.
  • Flexible Budget: Dynamically recalibrates revenues and variable expenses to reflect what they should have been for the actual level of activity achieved. This enables valid apples-to-apples performance comparisons.

3. Standard Costing and Variance Decomposition
Standard costs are carefully pre-calculated target milestones for material, labor, and overhead inputs per unit. Discrepancies between actual results and standard targets are isolated into specific variances:
Direct Material Variances

  •

    Material Price Variance (at purchase)

    “MPV” = “Actual Quantity Purchased (AQ)” × (“Actual Price (AP)” − “Standard Price (SP)”)


  •

    Material Quantity (Usage) Variance (at production)

    Under the standard “isolated at production” approach, it’s typically computed using standard price times the difference between actual quantity used and standard quantity allowed:

    “MQV” = “Standard Price (SP)” × (“Actual Quantity Used (AQ)” − “Standard Quantity Allowed (SQ)”)

     

Direct Labor Variances

  • Labor Rate Variance (LRV)

    “LRV” = “Actual Hours Worked (AH)” × (“Actual Rate Paid (AR)” − “Standard Rate (SR)”)

    Labor Efficiency Variance (LEV)

    “LEV” = “Standard Rate (SR)” × (“Actual Hours Worked (AH)” − “Standard Hours Allowed (SH)”)
