Inventory Shrinkage Journal Entries: How to Record Lost, Stolen, and Damaged Inventory

Inventory shrinkage is the difference between the inventory your records say you have and what you actually count on the warehouse floor. When you count 980 units but the books show 1,000, you have 20 units of shrinkage. Somewhere along the way those units walked off, got damaged, broke in shipping, or were miscounted at receiving. The basic adjusting journal entry under a perpetual inventory system: Dr. Cost of Goods Sold X Cr. Inventory X Where X = (book value per unit) × (units of shrinkage). If the 20 missing units cost $15 each, the entry is $300. This reduces the inventory asset to match the physical count and charges the loss against this period's cost of goods sold. Some companies and some textbooks prefer a separate Shrinkage Expense (or Inventory Loss) account instead of folding the hit into COGS. The choice depends on materiality: small, recurring shrinkage gets buried in COGS because that is where normal operating losses belong. Large or unusual shrinkage (theft, fire damage, a warehouse flood) gets its own account so managers can see it and investigate. Either treatment reduces net income by the same amount — the only difference is which expense line on the income statement carries the loss. Snap a photo of any inventory shrinkage problem and AccountingIQ identifies whether the system is perpetual or periodic, calculates the shrinkage amount, and walks through the exact journal entry with the right accounts for your textbook's convention.

Perpetual inventory systems update the Inventory account after every purchase, every sale, and every return. At any moment, the book value reflects management's best record of what should be on the shelves. Shrinkage is the reconciliation between that book value and a physical count, usually taken quarterly or annually. Perpetual example: the general ledger shows 5,000 units of product X at $12 each = $60,000 book value. Year-end count finds 4,920 units. Shrinkage = 80 units × $12 = $960. Entry: Dr. Cost of Goods Sold $960 / Cr. Inventory $960. Periodic inventory systems do NOT update Inventory for every transaction. Instead, they run a calculation at period-end: Beginning Inventory + Purchases - Ending Inventory = Cost of Goods Sold. Whatever is "missing" automatically flows through COGS because COGS is the plug. Under periodic, shrinkage is invisible in the entry itself — it is baked into the COGS calculation through the Ending Inventory adjustment. Periodic example: Beginning Inventory $40,000 + Purchases $100,000 = $140,000 Goods Available. Physical count of Ending Inventory = $58,000. COGS = $140,000 - $58,000 = $82,000. The physical count number goes straight into the formula. Any shrinkage is automatically included in the $82,000 COGS. There is no separate shrinkage entry because the system doesn't track inventory book value between counts. The trick on exams: questions that hand you a perpetual system and give you a physical count are asking for the adjusting entry. Questions that describe a periodic system with a count are asking you to recalculate COGS. Know which system the question is describing before you start the entry — this is where most students lose points. AccountingIQ identifies the inventory system from the problem context (perpetual problems mention "the inventory account shows" or "per the records", periodic problems focus on "ending inventory") and applies the correct treatment.

Most shrinkage is a normal part of running an inventory business and flows through COGS. But some circumstances require a different account entirely. Theft or pilferage: when shrinkage is clearly the result of theft (confirmed by investigation, security footage, or employee admission), companies often record it as a separate Loss From Theft or Security Loss account. The entry: Dr. Loss From Theft / Cr. Inventory. This puts the loss below operating income on the income statement because it is not part of normal operations. Material theft losses may also trigger insurance recovery — if recovered, the entry is Dr. Cash / Cr. Loss From Theft (or Other Income), reversing part or all of the original loss. Damage or obsolescence: damaged inventory that cannot be sold at full price is typically written down rather than written off entirely. If a company has $5,000 of water-damaged product that can still be sold at a deep discount for $1,500, the entry is: Dr. Loss on Inventory Write-Down $3,500 / Cr. Inventory $3,500. The remaining $1,500 stays in inventory at its lower market value (applying the Lower of Cost or Market rule). If the inventory is totally worthless, write off the full cost: Dr. Loss on Inventory Write-Off $5,000 / Cr. Inventory $5,000. Normal spoilage vs abnormal spoilage: this distinction matters in cost accounting and manufacturing. Normal spoilage (yield loss, expected waste in production) gets absorbed into the cost of good units produced — it is part of manufacturing overhead. Abnormal spoilage (a batch that failed quality control, production error) is charged to a Loss from Abnormal Spoilage account in the period incurred. The exam trap: students treat all spoilage as inventory loss. Only abnormal spoilage is a separate loss; normal spoilage stays in the cost of production. Casualty losses (fire, flood, natural disaster): these go to a dedicated Casualty Loss account, with insurance proceeds offsetting the loss. Large casualty losses may qualify for extraordinary item treatment on older income statements, though GAAP no longer classifies anything as extraordinary under ASC 225. AccountingIQ identifies the cause of inventory loss from the problem context and selects the appropriate account — theft vs COGS vs casualty vs write-down — along with the proper journal entries.

Scenario: Widgetworks Inc uses a perpetual inventory system. At year-end, the Inventory account shows $485,000. The physical count totals $468,500. Investigation reveals the following: $3,200 of product was damaged in shipping (salvageable at $1,000), $2,500 was confirmed stolen from the warehouse, and the remaining difference is unexplained shrinkage attributed to miscounts and normal breakage. Step 1: Calculate the total shortage. Book value: $485,000 Physical count: $468,500 Total shortage: $16,500 Step 2: Allocate the shortage to causes. Damaged (write-down to salvage value): $3,200 - $1,000 = $2,200 Confirmed theft: $2,500 Unexplained shrinkage: $16,500 - $2,200 - $2,500 = $11,800 Plus: damaged inventory still on books at $1,000 salvage value (was previously $3,200) Wait — the damaged inventory calculation needs care. The $3,200 is already inside the $16,500 because the damaged goods were counted as worthless at physical count. To reconcile: we need to leave $1,000 in inventory (salvage value) and write off the other $2,200 to a loss account. Actual journal entries: Entry 1 (record salvage): Dr. Inventory $1,000 / Cr. Loss on Damaged Inventory $1,000 (recognizing that we still have $1,000 of value). Entry 2 (write-down of damaged): Dr. Loss on Damaged Inventory $3,200 / Cr. Inventory $3,200 (write off the original cost). Entry 3 (confirmed theft): Dr. Loss From Theft $2,500 / Cr. Inventory $2,500. Entry 4 (unexplained shrinkage to COGS): Dr. Cost of Goods Sold $10,800 / Cr. Inventory $10,800. Verify: Total credits to Inventory = $3,200 + $2,500 + $10,800 - $1,000 = $15,500. But our shortage was $16,500. The $1,000 difference is the salvage value we left in inventory — because the physical count counted the damaged goods at ZERO, but they have $1,000 of salvage value that should stay on the books. Simplified approach (what most textbooks use): assume the physical count correctly reflects market value, so no salvage adjustment. Entries become: Dr. Loss on Damaged $2,200 / Dr. Loss From Theft $2,500 / Dr. COGS $11,800 / Cr. Inventory $16,500. Total debits = $16,500, matches the shortage. AccountingIQ handles the full reconciliation automatically — including the subtle salvage value adjustments — and shows both the rigorous approach and the textbook-simplified version so you can match whichever your professor expects.
