A vital component of running a business is Inventory Management. The terms Opening Stock and Closing Stock are essential in this procedure. We'll go over opening stock, closing stock, its components, the formula that determines it, and a practical example to help you grasp it all in this blog post.
Opening stock, often called beginning inventory or initial stock, is the entire amount of supplies, materials, or finished items that a company has on hand at the start of a financial year. This figure is the beginning point for inventory management and financial reporting as it reflects the stock carried over from the prior period.
#3 What is the formula of opening stock?
It is simple and quick to calculate opening stock and manage opening stock in the trial balance. Depending on the available facts, it can be computed in various methods. Here are a few formulae to help you calculate it:
Case 1: When different types of opening stocks are mentioned: Opening Stock = Raw Material Cost + Work in Progress Values + Finished Product Cost
Case 2: When sales, cost of goods sold, gross profit, and current year closing stock statistics are given together: Opening Stock = (Sales - Gross Profit - Cost of Goods Sold) + Closing Stocks
Let's look at an example: Assume that on the 1st of January each year, your bakery's fiscal year starts. Your closing stock, which included flour, sugar, and baked products, was valued at Rs.50,000 on the 31st of December the previous year.
The value of this stock becomes your starting stock for the year when 1st of January arrives. Now that you have Rs.50,000 to start your bakery operations for the year, you may buy wheat, sugar, and baked items.
Inventory management, cost containment, and financial reporting all heavily depend on opening stock. Throughout the accounting period, it offers a clear starting point for monitoring variations in inventory levels, calculating expenses, and making defensible choices on pricing and restocking. Recognizing and precisely computing opening stock is significant for all types of businesses irrespective of their size.
Closing stock, also known as "ending inventory" or "ending stock," is the entire amount of supplies, materials, or finished items that a company has on hand after an accounting period, such as a fiscal year or a financial reporting period. This figure represents the inventory that is still available and is the foundation for carrying forward inventory into the subsequent accounting period.
By averaging the expenses of every unit in stock, the average costing approach determines the cost of inventory.
Let's say a toy store has one hundred identical automobiles. They had bought 50 automobiles for Rs. 50 apiece and another 50 cars for Rs. 60 each at the start of the year. The formula to get the average cost of a hundred toy cars is Average Cost = (Rs. 2500 + Rs. 3000) / 100 vehicles = Rs. 550 for each car.
The average costing technique and the weighted average costing method are comparable; however, the weighted average costing approach bases each unit's cost on the quantity purchased at each price. When the units are different, it works best.
Example: The weighted average cost is determined using the number and cost of each batch of 50 toy cars at the same toy store, provided that the first batch is not identical to the second batch.
Every time a new transaction is made, the moving average costing approach modifies the average cost. When inventory costs change regularly, it's very helpful.
If the toy store buys 20 more cars for Rs.550 each, the new average cost becomes New Average Cost = (Rs.2500 + Rs.3000 + Rs.11000) / 120 cars = Rs.137.5 per car
The oldest inventory is assumed to be sold first via FIFO. The closing stock is valued at the cost of the most recent acquisitions.
For instance, if the toy business uses the first-in-first-out (FIFO) method and sells thirty cars, it will be assumed that the first thirty vehicles, which were bought for Rs.50 each, were sold. The closing stock will be evaluated at the second-in, second-out cost (Rs.60 per car).
The newest inventory is assumed to be sold first via LIFO. The closing stock is valued at the price of the earliest acquisitions.
As an illustration, if the toy business employs LIFO and sells thirty cars, it is assumed that the final thirty vehicles from the second batch—which were bought at Rs.60 each—were sold. The closing stock is therefore valued at the cost of the first batch Rs.50 per car.
The closing stock is valued using this approach at the cost of the most recent acquisition.
For instance, if the toy business sells 30 cars and values the closing stock using the cost of the most recent acquisition, it would be valued at Rs.60 per vehicle.
When a company wants to display a zero value for the closing stock, they employ this strategy. It implies that the inventory goods are worthless and of no cost.
For example, when it comes to products like samples, giveaways, or charitable donations that have no residual market worth, a company may decide to apply the zero-cost technique.
The closing stock formula is determined by the inventory valuation technique that is used. Here are the formulas for LIFO, FIFO, and Weighted Average Cost:
1. Average Cost & Moving Average Cost (MAC): (Total Cost of Inventory / Total Quantity of Inventory)
2. FIFO: Closing Stock = Total Quantity in Inventory - Quantity Sold x Cost of Oldest Inventory
3. LIFO: Closing Stock: = Total Quantity in Inventory - Quantity Sold x Cost of Most Recent Inventory
4. Weighted Average Cost: Closing Stock = Total Cost of Goods in Inventory / Total Quantity in Inventory
Let's use a real-world example to demonstrate how closing stock is calculated:
Let's say a small electronics retailer assesses its closing stock of smartphones using the FIFO approach. It possessed 50 cell phones at the start of the accounting period, each costing Rs.3000 to buy. It sold 30 of these cell phones during the year.
We utilize the FIFO formula to determine the closing stock:
Closing Stock is calculated as follows: **Total Inventory - Sold Quantity x Cost of Oldest Inventory (50-30) X Rs.3000 20 X Rs.3000 = Closing Stock
Rs.60,000 is the closing stock.
Thus, after the accounting period, the closing stock value of smartphones is Rs.60,000.
For organizations, closing stock is a crucial number since it impacts profitability, tax obligations, and financial reporting. Making wise company decisions and preserving the integrity of financial accounts depend on accurate calculation. The assessment technique selected should be in line with the demands and nature of the business.
Here's the comparison between opening stock and closing stock, considering multiple parameters and aspects: 1. Definition:
Opening Stock - The value of inventory at the beginning of an accounting period. Closing Stock - The value of inventory at the end of an accounting period.
2. Timing:
Opening Stock - Represents the initial inventory available at the start of the accounting period. Closing Stock - Represents the remaining inventory after the accounting period.
3. Purpose:
Opening Stock - Serves as the starting point for inventory management and financial reporting. Closing Stock - Determines the value of inventory remaining after sales and usage.
4. Components:
Opening Stock - Comprises finished goods, raw materials, and work-in-progress (WIP). Closing Stock - Includes products, materials, or goods that are still on hand.
5. Calculation Formula:
Opening Stock - Closing Stock of the Previous Period. Closing Stock - Various methods such as FIFO, LIFO, or Weighted Average Cost are used to calculate closing stock.
6. Financial Reporting Impact:
Opening Stock - Affects the balance sheet at the beginning of the accounting period. Closing Stock - Impacts the balance sheet at the end of the accounting period.
7. Cost Allocation:
Opening Stock - Influences the initial cost allocation for inventory items. Closing Stock - Determines the cost allocation of inventory items remaining in stock.
8. Decision-Making Role:
Opening Stock - Helps plan production, procurement, and pricing strategies for the accounting period. Closing Stock - Guides decisions related to restocking, pricing, and resource allocation.
9. Inventory Management:
Opening Stock - Sets the stage for inventory control and tracking during the accounting period. Closing Stock - Reflects the outcome of inventory management practices during the accounting period.
10. Example:
Opening Stock - At the start of the year, a retail store has Rs.10,000 worth of clothing, Rs.5,000 worth of raw materials, and Rs.2,000 worth of partially assembled furniture. Closing Stock - At the end of the year, the retail store has Rs.15,000 worth of clothing, Rs.2,000 worth of raw materials, and Rs.3,000 worth of completed furniture.
The above comparison highlights the key differences between opening and closing stock in terms of their definitions, timing, components, calculation methods, and their roles in financial reporting and decision-making. Opening stock provides the starting point for inventory management while closing stock reflects the outcome of inventory control efforts at the end of the accounting period.
