The EOQ formula is the square root of (2 x 1,000 pairs x $2 order cost) / ($5 holding cost) or 28.3 with rounding. The ideal order size to minimize https://www.wave-accounting.net/ costs and meet customer demand is slightly more than 28 pairs of jeans.

Conversely, if the business firm buys smaller quantities in too many orders during a year, the ordering cost goes up.
However, as lower quantity of inventory is ordered each time, the number of orders needed to increase in order to fulfill the annual demand which leads to higher ordering costs.

The EOQ formula is one of several inventory calculations that small businesses can use to make their inventory management workflows more efficient. The Economic Order Quantity (EOQ) is known as a cash flow tool that helps to control cash that has been held down in a company’s inventory balance.
