Where Do You Put Wip Finished When Calculating Cog Mfg

Accounting Methods for WIP and Finished Goods

There are three primary accounting methods for tracking inventory: FIFO (First-In, First-Out), LIFO (Last-In, First-Out), and Weighted Average. Each method affects how WIP and finished goods are accounted for in COGMFG calculations.

FIFO Method

Under FIFO, the oldest inventory is sold first. This method:

• Provides the most accurate representation of current inventory
• Results in higher COGMFG when inventory is sold at higher prices
• Is required for certain industries like food and beverage

LIFO Method

LIFO assumes newer inventory is sold first. This approach:

• Can result in lower COGMFG figures
• Is often used to defer taxes by creating larger taxable income
• Is prohibited in certain industries

Weighted Average Method

The weighted average method calculates COGMFG based on the average cost of all inventory:

• Provides a balanced view between FIFO and LIFO
• Is commonly used for tax purposes
• Does not track individual inventory items

Calculation Process

The COGMFG calculation process involves several steps:

1. Determine the cost of direct materials
2. Add direct labor costs
3. Include manufacturing overhead
4. Account for WIP and finished goods inventory
5. Calculate ending inventory value

For WIP specifically, the accounting process differs based on the accounting method used. Under FIFO, WIP is valued at the cost of materials and labor added to it. Under LIFO, WIP is valued at the cost of the most recently added materials and labor.

Worked Example

Consider a manufacturing company with the following data:

• Beginning inventory: $50,000
• Direct materials: $120,000
• Direct labor: $80,000
• Manufacturing overhead: $40,000
• Ending inventory: $30,000

Using the weighted average method, the COGMFG calculation would be:

For WIP specifically, if $20,000 of the ending inventory is WIP valued at $15,000, the COGMFG would be adjusted accordingly based on the accounting method used.
