FIFO Method Study Notes

FIFO Method Overview

  • The FIFO (First-In, First-Out) method is a cost accounting method used in managerial accounting.

  • It is considered more accurate than the weighted-average method for calculating inventory costs.

Nature of FIFO Method

  • FIFO calculates unit costs using only the costs and outputs from the current period.

Learning Objective 6: Compute Equivalent Units of Production Using the FIFO Method

Step 1: Compute the Equivalent Units of Production
Part 2: Calculating Equivalent Units Needed to Complete Beginning WIP Inventory

  • Materials: - Formula: Beginning WIP units imes (100% - Percent Completed Materials)

  • Conversion: - Formula: Beginning WIP units imes (100% - Percent Completed Conversion)

Part 3: Units Started and Completed

  • Concept: Units started into production in the current period and also completed and transferred out in the same period.

Part 4: Equivalent Units in Ending WIP Inventory

  • Materials: - Formula: Ending WIP units imes Percent Complete Materials

  • Conversion: - Formula: Ending WIP units imes Percent Complete Conversion

Aggregate Calculation of Equivalent Units

  • Total Equivalent Units for Materials: - Formula: Equivalent Units (beginning WIP) + Units Started and Completed + Equivalent Units (ending WIP)

  • Total Equivalent Units for Conversion: - Formula: Equivalent Units (beginning WIP) + Units Started and Completed + Equivalent Units (ending WIP)

Learning Objective 7: Compute Cost per Equivalent Unit Using FIFO Method

Step 2: Compute Cost per Equivalent Unit
Calculation of Cost per Equivalent Unit (Part 1)

  • Cost per Equivalent Unit for Materials: Cost = \frac{Materials\ Cost}{Equivalent\ Units}

  • Cost per Equivalent Unit for Conversion: Cost = \frac{Conversion\ Cost}{Equivalent\ Units}

  • Total Cost per Equivalent Unit: Total = Cost\ per\ Equivalent\ Unit\ (Materials) + Cost\ per\ Equivalent\ Unit\ (Conversion)

Learning Objective 8: Assign Costs to Units Using FIFO Method

Step 3: Assign Costs to Units
Total Cost of Ending WIP Inventory

  • Calculating Cost of Materials in Ending WIP: - Formula: Equivalent Units (ending WIP materials) imes Cost per Equivalent Unit (materials)

  • Calculating Cost of Conversion in Ending WIP: - Formula: Equivalent Units (ending WIP conversion) imes Cost per Equivalent Unit (conversion)

  • Total Ending WIP Inventory Cost: - Formula: Cost of Materials in Ending WIP + Cost of Conversion in Ending WIP

Learning Objective 9: Prepare Cost Reconciliation Report Using FIFO Method

Step 4: Cost Reconciliation Report - Part 1

  • Costs to be Accounted For: - Formula: Cost of beginning WIP Inventory + Costs added during period

  • Costs Accounted For: - Formula: Cost of ending WIP Inventory + Cost of units transferred out

Comparison of Costing Methods

  • Concept: In many circumstances, the weighted-average and FIFO methods yield similar unit costs. FIFO is preferred for cost control as it prevents mixing current and previous period costs.

Conclusion

  • Concept: FIFO is beneficial for accurately reflecting current costs in financial statements and costing processes.
