Running a successful business in Pakistan—whether in retail, wholesale, e-commerce, or manufacturing—requires more than just buying and selling products. One of the most important financial and supply chain concepts every entrepreneur must master is ending inventory.
Ending inventory is the value of goods a business has in stock at the end of an accounting period. Knowing how to calculate ending inventory correctly helps you:
- Understand your cost of goods sold (COGS)
- Accurately report financial statements
- Plan for future purchases and avoid stockouts
- Improve profit margins
- Prevent tax miscalculations
For Pakistani entrepreneurs working with growing supply chains, logistics, and distribution networks, calculating ending inventory is vital. Companies like Max 3PL specialize in helping businesses manage logistics, warehousing, and supply chain operations, but entrepreneurs must still understand the mathematics behind inventory.
This guide will break down everything you need to know about the formula for ending inventory—with examples, formulas, and applications—so that you can make smarter financial and business decisions.
What is Ending Inventory?
Ending inventory refers to the value of unsold goods remaining at the end of a specific period—monthly, quarterly, or yearly. It is recorded on the balance sheet as an asset for the products and plays a direct role that is important in calculating COGS and gross profit.
Why is Ending Inventory Important?
- Financial Reporting – Without an accurate ending inventory, your income statement and balance sheet will be wrong.
- Tax Compliance – Overestimating or underestimating ending inventory that is important in business can lead to errors in tax reporting in Pakistan.
- Supply Chain Efficiency – Helps entrepreneurs avoid tying too much money in stock or running out of essential products.
- Decision Making – Knowing inventory levels guides decisions about purchasing, pricing, and discounting.
The Formula for Ending Inventory
The most common formula for calculating ending inventory is:
Ending Inventory = Beginning Inventory + Purchases – Cost of Goods Sold (COGS)
- Beginning Inventory (BI): The value of stock you had at the start of the period.
- Purchases (P): The value of inventory you purchased during the period.
- COGS: The cost of goods sold during the same period.
This formula provides the basic calculation, but entrepreneurs can apply more specific inventory valuation methods (FIFO, LIFO, Weighted Average).
Methods of Calculating Ending Inventory
- FIFO (First-In, First-Out)
- Oldest inventory items are sold first.
- Ending inventory reflects the most recent costs.
- Useful in Pakistan where inflation affects purchase costs (latest goods are more expensive).
Example:
If you buy rice at PKR 200 per bag in January and PKR 220 in February, FIFO assumes the PKR 200 stock is sold first, leaving PKR 220 stock in ending inventory.
- LIFO (Last-In, First-Out)
- Latest purchased inventory is sold first.
- Ending inventory reflects older costs.
- Less common in Pakistan due to IFRS standards, but conceptually important.
Example:
Using the rice example, LIFO assumes PKR 220 stock is sold first, leaving PKR 200 stock in ending inventory.
- Weighted Average Cost (WAC)
- Average cost per unit for the products is calculated and applied to all inventory.
- Smooths out price fluctuations.
Example:
If you purchased 100 units at PKR 200 and 100 units at PKR 220, the average cost per unit is PKR 210. The ending inventory is then calculated using PKR 210 per unit.
Ending Inventory in the Pakistani Context
Pakistani entrepreneurs face unique challenges such as fluctuating exchange rates, inflation, and supply chain delays. Understanding ending inventory helps mitigate these issues.
- E-commerce Sellers (Daraz, Shopify, Amazon Global Sellers from Pakistan): Accurate inventory prevents overselling.
- Retail Stores: Helps maintain stock levels and plan promotions.
- Wholesale Distributors: Avoids overstocking, which locks up cash flow.
- Manufacturers: Keeps raw materials from products made and finished goods in balance.
Common Mistakes in Ending Inventory Calculations
- Ignoring Damaged or Expired Stock – In Pakistan, FMCG and cosmetics businesses often face expired goods, which must be deducted.
- Incorrect Data Entry – Manual records lead to miscalculations.
- Not Matching Physical Counts – Always perform stock counts to verify calculations.
- Mixing Valuation Methods – Stick to one method consistently for accuracy.
Practical Example
Let’s say a Pakistani entrepreneur runs a clothing store in Lahore:
- Beginning Inventory: PKR 1,000,000
- Purchases: PKR 500,000
- COGS: PKR 800,000
Ending Inventory = 1,000,000 + 500,000 – 800,000 = PKR 700,000
This PKR 700,000 is reported on the balance sheet as an asset.
