An Easy Guide to Inventory Valuation and Depreciation 

Inventory valuation and depreciation are two of the most important concepts in accounting and financial management. Every business that sells goods must understand how to calculate inventory value and how depreciation affects assets and profits. Whether you run a small business, manage a large company, or study accounting, learning about inventory valuation methods, depreciation methods, financial statements, and tax impact is essential. In this complete guide, we will explain: What is inventory valuation What is depreciation Types of inventory valuation methods Types of depreciation methods Differences between inventory and fixed assets Impact on financial statements Tax benefits and accounting standards Practical examples 

Let’s start with the basics. 

What is Inventory Valuation? 

Inventory valuation is the process of calculating the monetary value of goods that a company holds for sale. Inventory includes: Raw materials Work-in-progress goods Finished goods 

Inventory valuation is important because it directly affects: Cost of Goods Sold (COGS) Gross profit Net income Balance sheet value Tax liability 

If inventory is valued incorrectly, profits can be overstated or understated. Why Inventory Valuation is Important 1. Determines accurate business profit 

2. Helps in pricing decisions 

3. Affects tax calculation 

4. Required for financial reporting 

5. Improves inventory management  

 Main Inventory Valuation Methods There are three major inventory valuation methods used worldwide: 1. FIFO (First In, First Out) FIFO assumes that the oldest inventory items are sold first. Example: If you purchased: 100 units at ₹50 100 units at ₹60 

If you sell 100 units, FIFO assumes they were sold at ₹50. Advantages of FIFO: Simple and easy Reflects current market price in balance sheet Higher profit during inflation 

Disadvantages: Higher tax during inflation

 2. LIFO (Last In, First Out) LIFO assumes that the latest inventory purchased is sold first. Using the same example: If you sell 100 units, they are assumed to be sold at ₹60. Advantages: Lower tax during inflation Matches recent cost with current revenue 

Disadvantages: Lower profit reporting Not allowed under IFRS (International Financial Reporting Standards)

 3. Weighted Average Cost Method This method calculates an average cost of inventory. Formula: Average Cost = Total Cost of Inventory / Total Units Example: Total cost = ₹11,000

Total units = 200 Average cost = ₹55 per unit Advantages: Smooth profit calculation Easy to use Reduces impact of price fluctuations

 Lower of Cost or Market (LCM) Businesses must report inventory at the lower of: Cost price Market value 

This rule prevents overstating assets. 

 What is Depreciation? Depreciation is the reduction in value of fixed assets over time due to: Wear and tear Usage Obsolescence Time 

Examples of depreciable assets: Machinery Equipment Vehicles Buildings Computers 

Depreciation helps match asset cost with revenue generated. 

 Why Depreciation is Important 1. Shows true asset value 

2. Reduces taxable income 

3. Follows accounting principles 

4. Helps in financial planning  

 Major Depreciation Methods 1. Straight Line Depreciation Method Most common method. Formula: Depreciation = (Cost – Salvage Value) / Useful Life Example: Machine cost = ₹1,00,000

Salvage value = ₹10,000

Useful life = 5 years Depreciation = (1,00,000 – 10,000) / 5 = ₹18,000 per year Advantages: Simple calculation Equal expense every year 

High search keyword: straight line depreciation formula 

 2. Written Down Value (WDV) Method Also called declining balance method. Depreciation is calculated on remaining value every year. Formula: Depreciation = Book Value × Rate Example: If machine value = ₹1,00,000

Rate = 20% Year 1 depreciation = ₹20,000

Remaining value = ₹80,000 Year 2 depreciation = ₹16,000 Advantages: Higher depreciation in early years Tax saving benefit

 3. Units of Production Method Depreciation based on actual usage. Formula: Depreciation per unit = (Cost – Salvage) / Total expected units Best for manufacturing businesses. 

 Difference Between Inventory and Depreciation Basis Inventory Depreciation Type Current asset Fixed asset

Nature Goods for sale Long-term asset

Value change Based on cost method Based on usage/time

Impact Affects COGS Affects operating expenses 

Inventory is not depreciated. Instead, its value changes through inventory valuation methods. 

Inventory vs Fixed Assets 

Inventory is sold in normal business operations Fixed assets are used to produce goods 

Example: Mobile phones in a shop = Inventory Shop furniture = Fixed asset   Impact on Financial Statements 1. Income Statement Inventory affects: Cost of Goods Sold Gross profit 

Depreciation affects: Operating expenses Net income   2. Balance Sheet Inventory appears under: Current Assets 

Depreciated assets appear under: Non-current Assets (after deduction of accumulated depreciation)   3. Cash Flow Statement Depreciation is a non-cash expense.

It reduces profit but does not reduce cash. 

 Tax Impact of Inventory Valuation and Depreciation Higher inventory value = Higher profit = Higher tax Higher depreciation = Lower profit = Lower tax 

Businesses often choose depreciation methods for tax planning. High search keyword: tax benefits of depreciation 

 Accounting Standards for Inventory and Depreciation Inventory Standards IAS 2 (International Accounting Standard) Ind AS 2 (India) GAAP guidelines 

Depreciation Standards IAS 16 Companies Act (India) Income Tax Act   Practical Example of Inventory and Depreciation Suppose a company: Purchases goods worth ₹5,00,000 Sells goods worth ₹3,00,000 Buys machine for ₹2,00,000 

Inventory affects: Cost of goods sold Gross profit 

Depreciation affects: Net profit 

Both together determine financial performance. 

 Common Mistakes in Inventory Valuation 1. Ignoring damaged goods 

2. Not applying LCM rule 

3. Mixing FIFO and average method 

4. Incorrect physical stock count  

 Common Depreciation Errors 1. Wrong useful life estimation 

2. Ignoring salvage value 

3. Not updating asset register 

4. Using wrong depreciation rate
