Inventory Valuation: Definition, Importance & Methods
Are you running a business and managing inventory?
We know that one of the most daunting and time-consuming tasks you face is inventory valuation. This crucial process goes beyond just counting stock; it significantly impacts your financial reporting, tax calculations, and strategic planning. Whether you’re dealing with raw materials, work-in-progress, or finished goods, accurate inventory valuation is essential.
Let's explore how you can streamline this critical aspect of your business operations and make it more manageable.
What is Inventory Valuation and Why It’s Important?
Inventory valuation is the process of assigning monetary value to a company's inventory at the end of an accounting period. This valuation includes raw materials, work-in-progress, and finished goods. Accurately determining the value of inventory is crucial as it affects the cost of goods sold (COGS), gross profit, and net income on the financial statements.
Proper inventory valuation ensures compliance with accounting standards, aids in tax calculations, and provides valuable insights for business decision-making. By reflecting the true cost and value of inventory, businesses can maintain accurate financial records and optimise their inventory management strategies.
4 Types of Inventory Valuation Methods
There are several methods of inventory valuation, each offering distinct advantages and suited to different business types and industry standards. The most common methods include:
1. First-In, First-Out (FIFO)
In the FIFO (First-In, First-Out) inventory valuation method, inventory costs are calculated based on the assumption that the first items purchased are the first items sold. This affects both the cost of goods sold (COGS) and the ending inventory value. Here’s a step-by-step explanation:
Suitable for: Perishable goods, food products, and items with a limited shelf life.
Cost of Goods Sold (COGS)
1. Identify the earliest purchases: Start with the units purchased first.
2. Calculate the cost of the units sold: Use the cost of the earliest purchases to calculate COGS.
Ending Inventory
1. Identify the remaining units: After accounting for the units sold, determine which units remain.
2. Calculate the cost of the remaining units: Use the cost of the most recent purchases for the remaining units.
Example with Calculations
Purchase History:
January 1: 30 units at $50 each
January 10: 30 units at $55 each
January 20: 40 units at $60 each
Units Sold: 70 units
Step-by-Step Calculation
1. COGS:
Total COGS: $1,500 + $1,650 + $600 = $3,750
Ending Inventory:
Remaining units from January 20: 30 units × $60 = $1,800
Total Ending Inventory: $1,800
Explanation of Costs Used
COGS Calculation: Use the cost of the earliest purchases to determine COGS. In this example, the first 30 units at $50, the next 30 units at $55, and the last 10 units at $60.
Ending Inventory Calculation: Use the cost of the most recent purchases for the units remaining. After selling 70 units, the remaining 30 units are from the latest purchase batch (January 20) at $60 each.
This method ensures that the inventory costs reflect the actual flow of goods and the latest costs are assigned to the remaining inventory.
2. Last-In, First-Out (LIFO)
In the LIFO (Last-In, First-Out) method, inventory costs are calculated based on the assumption that the last items purchased are the first items sold. This affects both the cost of goods sold (COGS) and the ending inventory value. Here’s a step-by-step explanation:
Suitable for: Non-perishable goods, industries with inflationary prices, and businesses aiming to reduce tax liability in times of rising prices.
Cost of Goods Sold (COGS)
1. Identify the most recent purchases: Start with the units purchased last.
2. Calculate the cost of the units sold: Use the cost of the most recent purchases to calculate COGS.
Ending Inventory
Identify the remaining units: After accounting for the units sold, determine which units remain.
2. Calculate the cost of the remaining units: Use the cost of the earliest purchases for the remaining units.
Example with Calculations
Purchase History:
January 1: 30 units at $50 each
January 10: 30 units at $55 each
January 20: 40 units at $60 each
Units Sold: 70 units
Step-by-Step Calculation
1. COGS:
First 40 units from January 20: 40 units × $60 = $2,400
Next 30 units from January 10: 30 units × $55 = $1,650
Total COGS: $2,400 + $1,650 = $4,050
2. Ending Inventory:
Remaining units from January 1: 30 units × $50 = $1,500
Total Ending Inventory: $1,500
Explanation of Costs Used
COGS Calculation: Use the cost of the most recent purchases to determine COGS. In this example, the first 40 units at $60, and the next 30 units at $55.
Ending Inventory Calculation: Use the cost of the earliest purchases for the units
remaining. After selling 70 units, the remaining 30 units are from the earliest purchase batch (January 1) at $50 each.
This method ensures that the inventory costs reflect the actual flow of goods and the earliest costs are assigned to the remaining inventory.
3. Weighted Average Cost
In the Weighted Average Cost method, inventory costs are calculated based on the average cost of all units available for sale during the period. This affects both the cost of goods sold (COGS) and the ending inventory value. Here’s a step-by-step explanation:
Suitable for: Companies with large volumes of similar items and non-perishable goods.
Cost of Goods Sold (COGS)
1. Calculate the total cost of all units available for sale.
2. Calculate the weighted average cost per unit.
3. Calculate the cost of the units sold using the weighted average cost per unit.
Ending Inventory
Calculate the cost of the remaining units using the weighted average cost per unit.
Example with Calculations
Purchase History:
January 1: 30 units at $50 each = $1,500
January 10: 30 units at $55 each = $1,650
January 20: 40 units at $60 each = $2,400
Total Units Purchased: 100 units Total Cost of Units Purchased: $1,500 + $1,650 + $2,400 = $5,550
Units Sold: 70 units
Step-by-Step Calculation
1. Weighted Average Cost Per Unit:
Total Cost of Units Purchased / Total Units Purchased = $5,550 / 100 units = $55.50 per unit
2. COGS:
Units Sold × Weighted Average Cost Per Unit = 70 units × $55.50 = $3,885
3. Ending Inventory:
Remaining Units × Weighted Average Cost Per Unit = 30 units × $55.50 = $1,665
Explanation of Costs Used
COGS Calculation: Use the weighted average cost per unit to determine COGS. In this example, 70 units at $55.50 each.
Ending Inventory Calculation: Use the weighted average cost per unit for the units remaining. After selling 70 units, the remaining 30 units are valued at the weighted average cost of $55.50 each.
This method smooths out price fluctuations over the accounting period and assigns an average cost to both COGS and ending inventory.
4. Specific Identification
In the Specific Identification method, inventory costs are calculated based on the actual cost of each specific item sold. This method directly tracks the cost of each item, affecting both the cost of goods sold (COGS) and the ending inventory value. Here’s a step-by-step explanation
Suitable for: Businesses with unique, high-value items such as cars, real estate, and luxury goods.
Cost of Goods Sold (COGS)
1. Identify the specific items sold and their actual costs.
2. Calculate the cost of the units sold using the actual costs of those specific items.
Ending Inventory
1. Identify the remaining items and their actual costs.
2. Calculate the cost of the remaining units using their actual costs.
Example with Calculations
Purchase History:
January 1: 30 units at $50 each (Serial Numbers 001-030)
January 10: 30 units at $55 each (Serial Numbers 031-060)
January 20: 40 units at $60 each (Serial Numbers 061-100)
Units Sold: 70 units (Serial Numbers 001-030, 031-060, and 10 units from 061-070)
Step-by-Step Calculation
1. COGS:
First 30 units from January 1 (Serial Numbers 001-030): 30 units × $50 = $1,500
Next 30 units from January 10 (Serial Numbers 031-060): 30 units × $55 = $1,650
Remaining 10 units from January 20 (Serial Numbers 061-070): 10 units × $60 = $600
Total COGS: $1,500 + $1,650 + $600 = $3,750
2. Ending Inventory:
Remaining 30 units from January 20 (Serial Numbers 071-100): 30 units × $60 = $1,800
Total Ending Inventory: $1,800
Explanation of Costs Used
COGS Calculation: Use the actual costs of the specific items sold to determine COGS. In this example, the costs are $50, $55, and $60 per unit for the respective serial numbers.
Ending Inventory Calculation: Use the actual costs of the specific items remaining. After selling 70 units, the remaining 30 units are from the latest purchase batch (January 20) at $60 each.
This method ensures that the inventory costs reflect the actual costs of the specific items sold and remaining.
