The opening stock for the current period is usually derived from the stock available after the conclusion of sales from the last accounting period, based on the nature of the business.

These units have passed all the manufacturing process, but are not yet sold or distributed to the customers. These units are ready for the market for further trading and earn revenue for the entity. These are the final product of the entity and are intended for sale. They are also called ready to sale goods.

Formula for Calculating Opening Stock

Opening Stock = (7,50,000 + 70,000 + 2,60,000) – (50,000 + 6,50,000)

Opening Stock = ₹3,80,000
