Stock valuation is not merely an accounting policy choice—it is a profit-determining decision.The method adopted for stock valuation has a direct and immediate impact on Gross Profit, Net Profit, tax liability, and audit outcomes.
1. Introduction — Why Stock Valuation Deserves Special Attention
Closing stock valuation directly affects:
Cost of Goods Sold (COGS)
Gross Profit margin
Taxable income
GST ITC reversals
Credibility of financial statements
Even with the same physical stock, different valuation methods can produce different profits.
Impact: Incorrect or inconsistent stock valuation is a common trigger for rejection of books and income estimation.
2. Objective
To ensure that at year-end:
Correct valuation method is applied
Method is consistently followed year-on-year
Impact on P&L is understood and controlled
Valuation is compliant with accounting standards
Documentation supports valuation decisions
3. Accounting Principle Governing Stock Valuation
Stock must be valued at:
Cost or Net Realisable Value (NRV), whichever is lower
This principle is based on:
Prudence
Matching concept
AS-2 / Ind AS-2
4. Common Stock Valuation Methods Used by SMEs
A. FIFO (First In, First Out)
Under FIFO:
Oldest inventory is assumed to be sold first
Closing stock consists of latest purchases
Impact on P&L:
Higher closing stock during inflation
Higher profit
Higher tax liability
FIFO generally reflects current cost in balance sheet.
B. Weighted Average Cost (WAC)
Under WAC:
Average cost of all purchases is applied
Smoothens price fluctuations
Impact on P&L:
Moderate closing stock value
Stable profit margins
Less volatility
C. Specific Identification (Limited Use)
Used where:
Items are uniquely identifiable
High-value or customised goods
Not common for bulk-trading SMEs.
5. CABTA Framework — “Choosing the Right Valuation Method”
Step 1 — Understand Business Nature
Trading → FIFO / WAC
Manufacturing → WAC more common
Price volatility → WAC preferred
Step 2 — Ensure Consistency
Once adopted:
Method should not be changed frequently
Any change must be disclosed and justified
Frequent method changes attract audit and tax suspicion.
Step 3 — Evaluate Impact on Profit
Simulate:
Closing stock under FIFO
Closing stock under WAC
Understand profit sensitivity before finalisation.
Step 4 — Check NRV Applicability
Even if cost is higher:
Damaged / obsolete stock must be written down
Slow-moving stock requires review
Ignoring NRV overstates profit.
Step 5 — Align With Prior Years & Audit History
Sudden GP changes without explanation are red flags.
6. GST Implications in Stock Valuation
GST must be excluded from stock valuation if ITC is available
ITC reversal required on lost / destroyed stock
Valuation errors lead to GST reconciliation mismatches
