Abnormal Loss in Accounting: 7 Key Causes and Treatment Methods
Abnormal Loss in Accounting
Business processes aren’t always smooth. Sometimes, disruptions cause unexpected losses beyond the norm. These losses—unforeseen, avoidable, and often costly—are known as abnormal losses. Whether it’s due to fire, theft, or careless handling, abnormal loss in accounting is treated separately from normal, expected losses. Businesses must report it transparently, and accountants must ensure accurate classification, valuation, and disclosure.
What is Abnormal Loss in Accounting?
Abnormal loss refers to any loss incurred during the production or distribution process that exceeds the anticipated or standard level of loss. Unlike normal loss, which is inevitable and factored into cost pricing, abnormal loss is not expected and is usually the result of accident, inefficiency, negligence, or uncontrollable external events.
Examples:
Spoilage of goods in transit due to flooding
Theft from inventory
Fire destroying raw materials
Machine malfunction leading to wasted units
It must be separately accounted for as a financial loss in the Profit and Loss Account.
Difference Between Normal and Abnormal Loss
Feature | Normal Loss | Abnormal Loss |
---|---|---|
Predictability | Expected and recurring | Unexpected and unusual |
Treatment | Included in product cost | Charged directly to P&L |
Control | Uncontrollable | Often preventable |
Examples | Evaporation, wear & tear | Fire damage, theft, flood |
Impact on costing | Absorbed in cost per unit | Not absorbed in cost per unit |
Causes of Abnormal Loss
Theft or Burglary
Fire or Explosions
Natural Disasters (Flood, Earthquake)
Machine Failures
Operator Negligence
Poor Quality Raw Materials
Inadequate Storage Facilities
These causes are generally outside the expected scope and can often be reduced with proper controls.
How to Calculate Abnormal Loss
Abnormal loss can be calculated in units or monetary value. Here’s the standard approach:
Example:
1,000 units input
10% expected normal loss → 100 units
Actual output = 850 units
So, abnormal loss = 1,000 – (850 + 100) = 50 units
If the cost per unit is ₹20:
Abnormal Loss Value = 50 × ₹20 = ₹1,000
Accounting Treatment of Abnormal Loss
The abnormal loss is not transferred to the cost of production. Instead, it’s charged directly to the Profit and Loss Account, and if insurance claim is recoverable, the net loss is only the uninsured portion.
Journal Entries for Abnormal Loss
Without Insurance:
Abnormal Loss A/c Dr. To Process A/c (Being abnormal loss recorded) Profit & Loss A/c Dr. To Abnormal Loss A/c (Being abnormal loss transferred to P&L)
With Insurance Recovery:
Insurance Co. A/c Dr. P&L A/c Dr. To Abnormal Loss A/c (Being abnormal loss partially recovered by insurance)
Examples of Abnormal Loss
Consignment Example:
Goods sent: 500 units
Cost per unit: ₹100
Normal loss: 5% → 25 units
Actual delivery: 450 units
Loss: 50 units → Abnormal loss = 25 units
Value = 25 × ₹100 = ₹2,500 (recorded in P&L)
Abnormal Loss in Financial Statements
It appears in:
Profit and Loss Account (as an expense)
Balance Sheet (if claim receivable is pending)
Never included in Cost of Goods Sold (COGS) or in Inventory.
Is Abnormal Loss a Cost or Expense?
It’s treated as a period expense since it’s unexpected and non-recurring. It does not inflate product costing.
Impact of Abnormal Loss on Profit
Abnormal loss reduces net income and should be closely monitored, especially if it recurs. It’s a red flag in audits and financial health checks.
Prevention and Control of Abnormal Loss
Staff training
Better machinery maintenance
Improved packaging and logistics
Fire and theft alarms
Inventory controls and documentation
Insurance coverage
Abnormal Loss in Process Costing
In industries using process costing (e.g., manufacturing, chemical), abnormal losses are isolated and not included in production overheads.
Difference Between Abnormal Loss and Impairment
Abnormal Loss | Impairment |
---|---|
Due to unexpected events | Due to asset value decline |
Charged as a direct expense | Non-cash write-down |
One-time event | Often longer-term |
How to Report Abnormal Loss (GAAP Perspective)
According to GAAP and IFRS:
It must be disclosed separately in financial statements.
Insurance recoverables shown as current asset
Net loss affects bottom-line profit
Time of Recognition
As soon as the loss is confirmed or discovered, it must be:
Measured
Accounted in the correct financial period
Delaying recognition may result in misstatement of profit.
Effect on Inventory Valuation
Inventory must be valued excluding the abnormal loss. This ensures accurate valuation of remaining stock.
Insurance Claims for Abnormal Loss
Enter full loss
Record claim separately as asset receivable
Adjust when claim is settled
Mistakes to Avoid While Recording Abnormal Loss
Booking it as part of production cost
Delaying recognition
Not documenting root cause
Ignoring insurance recoveries
FAQs on Abnormal Loss
Is abnormal loss unavoidable?
No, it is usually preventable with proper safeguards.
Can abnormal loss be insured?
Yes, most commercial insurance policies cover common causes like fire or theft.
What is the difference between abnormal and extraordinary loss?
Extraordinary losses are extremely rare (e.g., war); abnormal losses are rare but more predictable.
Is abnormal loss part of inventory?
No. It’s excluded from inventory and posted as an expense.
Can abnormal loss affect business valuation?
Yes. Recurring abnormal losses can lower perceived efficiency and profitability.
How do you calculate cost per unit excluding abnormal loss?
Use the net quantity after normal loss for valuation.
Conclusion: Importance of Accurate Abnormal Loss Accounting
Every business faces uncertainty, but smart businesses plan for it. Abnormal loss accounting ensures these rare disruptions don’t distort your financial records. With accurate classification, prompt recognition, and insurance planning, you can minimize financial damage and maintain the integrity of your reports.
