How do you account for inventory shrinkage, and what is the financial statement impact?

Inventory shrinkage occurs when the physical count reveals less inventory than the accounting records indicate. The treatment depends on the inventory system and the materiality of the loss.

Perpetual System — Shrinkage is Explicitly Identified

Because the perpetual system maintains a running balance, any shortfall from the physical count is recorded as an adjusting entry:

• Immaterial shrinkage: Debit COGS, Credit Inventory
• Material shrinkage: Debit a separate line item (e.g., "Inventory Shrinkage Loss"), Credit Inventory — reported as an operating expense or disclosed separately

Periodic System — Shrinkage is Buried in COGS

Under the periodic method, COGS is computed residually:

COGS = Beginning Inventory + Purchases − Ending Inventory

Since ending inventory is determined by physical count, any shrinkage is automatically included in COGS. You cannot separately identify how much of COGS is normal sales vs. shrinkage.

Worked Example — Pinnacle Retail Corp:

Pinnacle operates 45 retail stores using a perpetual system. During its fiscal year-end count:

Store Category	Book Inventory	Physical Count	Shrinkage
Electronics	$8,200,000	$7,940,000	$260,000
Apparel	$5,100,000	$4,985,000	$115,000
Home goods	$3,700,000	$3,660,000	$40,000
Total	$17,000,000	$16,585,000	$415,000

Shrinkage rate = $415,000 /$17,000,000 = 2.44%

Journal Entry:

Account	Debit	Credit
Cost of Goods Sold	$415,000
Inventory		$415,000

Impact on Financial Statements:

• Income Statement: Gross profit decreases by $415,000; net income falls by$415,000 × (1 − tax rate)
• Balance Sheet: Inventory (current asset) decreases by $415,000
• Cash Flow Statement: No cash impact — this is a non-cash adjustment. Under indirect method, the decrease in inventory would already be reflected in working capital changes.

Exam Tip: If a question asks you to compare profitability between a company using periodic vs. perpetual systems, remember that periodic hides shrinkage in COGS while perpetual can report it separately. This affects comparability of gross margins.
