Principles of Financial Accounting: Inventory Inventory Classification Merchandise Inventory Raw Materials Work in Process Finished Goods

What It Is

Inventory classification is a crucial concept in financial accounting that categorizes inventory into different types based on its stage of completion. This classification helps companies accurately value and report their inventory on the balance sheet. For example, if a company buys $10,000 of raw materials, it would classify them as merchandise inventory until they are converted into finished goods.

Key Concepts & Formulas

• Merchandise Inventory: Inventory that is ready for sale or has been sold but not yet delivered to customers.
  • Example: A company purchases $5,000 of merchandise inventory on credit. The merchandise inventory account is debited $5,000.
• Raw Materials: Materials used in the production process that have not yet been converted into finished goods.
  • Example: A company purchases $10,000 of raw materials on credit. The raw materials account is debited $10,000.
• Work in Process (WIP): Inventory that is partially completed but not yet finished.
  • Example: A company has $8,000 of WIP that is 50% complete. The WIP account is debited $8,000.
• Finished Goods: Inventory that is complete and ready for sale.
  • Example: A company has $12,000 of finished goods that are ready for sale. The finished goods account is debited $12,000.
• Cost of Goods Sold (COGS): The direct cost of producing or purchasing inventory.
  • Formula: COGS = Beginning Inventory + Purchases – Ending Inventory
  • Example: A company has beginning inventory of $5,000, purchases of $20,000, and ending inventory of $10,000. COGS = $5,000 + $20,000 – $10,000 = $15,000.
• Gross Profit: The profit earned from selling inventory.
  • Formula: Gross Profit = Sales – COGS
  • Example: A company sells $50,000 of inventory and has COGS of $15,000. Gross Profit = $50,000 – $15,000 = $35,000.

Journal Entry Examples

1. Purchasing Raw Materials: Dr. Raw Materials $10,000 Cr. Accounts Payable $10,000

Explanation: The raw materials account is debited to record the purchase of raw materials, and the accounts payable account is credited to record the liability to the supplier.

1. Converting Raw Materials to Work in Process: Dr. Work in Process $8,000 Cr. Raw Materials $8,000

Explanation: The work in process account is debited to record the conversion of raw materials to WIP, and the raw materials account is credited to record the decrease in raw materials inventory.

1. Selling Finished Goods: Dr. Cost of Goods Sold $12,000 Cr. Finished Goods $12,000

Explanation: The cost of goods sold account is debited to record the sale of finished goods, and the finished goods account is credited to record the decrease in finished goods inventory.

Common Mistakes

1. Mistake: Confusing debits and credits for expense accounts.
   • Correction: Remember that debits increase assets and expenses, and credits increase liabilities and equity.
2. Mistake: Not considering the normal balance of accounts when recording journal entries.
   • Correction: Always consider the normal balance of accounts when recording journal entries. For example, the raw materials account has a debit balance, so it should be debited when recording purchases.
3. Mistake: Not using the correct formula for COGS.
   • Correction: Use the formula COGS = Beginning Inventory + Purchases – Ending Inventory to calculate COGS.

Exam Tips

1. Tip: Remember that inventory is valued at the lower of cost or market (LCM) value.
2. Tip: Be careful when recording journal entries for inventory transactions. Make sure to consider the normal balance of accounts and use the correct formula for COGS.
3. Tip: Don't forget to consider the impact of inventory transactions on the balance sheet and income statement.

Quick Practice

1. A company purchases $15,000 of raw materials on credit. What is the journal entry to record this transaction? Dr. Raw Materials $15,000 Cr. Accounts Payable $15,000

Explanation: The raw materials account is debited to record the purchase of raw materials, and the accounts payable account is credited to record the liability to the supplier.

1. A company has beginning inventory of $5,000, purchases of $20,000, and ending inventory of $10,000. What is the COGS? COGS = $5,000 + $20,000 – $10,000 = $15,000

Explanation: The COGS is calculated using the formula COGS = Beginning Inventory + Purchases – Ending Inventory.

1. A company sells $50,000 of inventory and has COGS of $15,000. What is the gross profit? Gross Profit = $50,000 – $15,000 = $35,000

Explanation: The gross profit is calculated using the formula Gross Profit = Sales – COGS.

Last-Minute Cram Sheet
