CAF 5 | Marginal & Absorption costing with Process costing | Spring 2026 Q7 | Sir Taha Popatia

This video, presented by Sir Taha Popatia, provides a comprehensive walkthrough of a complex management accounting problem from the Spring 2026 CAF 5 exam (Question 7). The problem integrates concepts from Marginal Costing, Absorption Costing, and Process Costing, which the presenter warns is a challenging combination. Key Topics and Breakdown: Problem Overview (0:08 - 2:00): The presenter introduces the problem regarding Saffron Industries Limited (SIL) and highlights the necessity of having a strong grip on manufacturing accounts and process costing before attempting it. Data Extraction & Initial Calculations (2:00 - 5:00): Detailed analysis of sales, revenue, material purchases, labor costs, depreciation, and manufacturing expenses. The presenter emphasizes pausing the video to perform these calculations manually. Inventory and Consumption (5:00 - 7:00): Working out the consumption values for stores, spares, and raw materials by accounting for opening and closing inventories. Process Costing Concepts (7:00 - 10:00): Explanation of Equivalent Production Units (EPU) for opening and closing Work-in-Process (WIP) and determining the total units produced (26 million). FIFO Method Application (11:26 - 13:30): Discusses the application of the FIFO (First-In-First-Out) method for inventory valuation and calculating the EPU for the current year (26.1 million units). Marginal Costing P&L Preparation (14:00 - 23:35): The presenter demonstrates the solution using a Process Costing T-account approach to isolate variable production costs. He explains how to differentiate between variable and fixed costs to arrive at the final Contribution and Net Profit figures. Recommendation: The presenter stresses that while the problem may look straightforward, it requires rigorous practice. He advises viewers to follow his alternative, structured T-account approach to minimize errors in the exam. He notes that while the ICAP approach is valid, his method provides better clarity for students.
