Concept explainers
a)
To calculate: The value of ordering cost.
Introduction:
Economic order quantity (EOQ):
EOQ is the quantity of units a company must add to its inventory so as to minimize the total inventory costs. It will determine the ideal order quantity which will decrease the inventory management costs.
Ordering cost:
Ordering cost is the cost incurred for single order. The order cost is essential for calculating EOQ.
b)
To determine: The impact if the true ordering cost is much greater than calculated ordering cost.

Under the EOQ policy, a particular product has been ordered with a Q* 80. A recent evaluation of holding costs shows that because of an increase in the interest rate associated with bank loans, the annual holding cost rate should be 27%. a. What is the new economic order quantity for the product? b. Develop a general expression showing how the economic order quantity changes when the annual holding cost rate is changed from I to Iarrow_forward
- A local distributor for Hankook tires Company expects to sell 12,600 R14 radial tires nest year. The estimated cost of keeping a R14 tire per annum is ȼ126 and ordering cost is ȼ70. d) What is the annual total cost if the optimal quantity is ordered?arrow_forwardAll Seasons Flower Shop uses 870 clay pots a month. The pots are purchased at $ 6 each. Annual holding cost per pot is estimated to be 35% of purchase cost. Ordering cost is $ 40 per order. The shop operates 12 months in a year. What would be the difference in total cost if an order quantity of 1000 is used instead of the EOQ. Note: calculate the difference as “total cost with Q = 1000 – total cost with EOQ”.arrow_forwardZartex Co. produces fertilizer to sell to wholesalers. One raw material – calcium nitrate – is purchased from a nearby supplier at $22.50 per ton. Zartex estimates it will need 5,750,000 tons of calcium nitrate next year. The annual holding cost for this material is 40% of the acquisition cost, and the ordering cost is $595. a) What is the most economical order quantity? b) How many orders will be placed per year? c) How much time will elapse between ordersarrow_forward
- Your distribution company has an annual demand of 1,400 lawn mowers. The cost of a lawn mower is $400. Carrying cost is estimated to be 20% of unit cost, and the ordering cost is $25 per order. If you order in quantities of 330 or more, you can get a 5% discount. Do a complete “EOQ with Discount” calculation and determine the optimal order quantity. Please show all calculations.arrow_forwardAn engineer has decided to pursue ordering option for a particular item on an as needed basis as oppose to stocking it. To stock the item, inventory inspection costs $500 annually. The cost to place an order is estimated at $125. For the ordering option, there is an additional $85 special delivery charge per order. Demand for the $20 item is 2,300 units per year. The annual holding cost rate is 40% of the item price. Calculate range of the order quantity that will make it economical to order this item every time. If the engineer decides to stock the item what is the order quantity that is economical.arrow_forwardthe economic order quantity (see Chapter 12 for EOQformulas) for its halogen lamps.

- Flamingo purchases 8,000 litres of ink each year for its production processes. The unit cost per litre is GH¢10, and the cost of carrying one litre of ink in inventory is GH¢3 per annum. Ordering cost is GH¢30 per order. Assuming that the firm operates on a 252-day working year, compute: (i). Optimal order quantity (ii). Total minimum inventory cost (iii). Expected number of orders placed each year (iv). Expected time between ordersarrow_forwardSuppose that the R&B Beverage Company has a soft drink product that shows a constant annual demand rate of 3600 cases. A case of the soft drink costs R&B $3. Ordering costs are $20 per order and holding costs are 25% of the value of the inventory. R&B has 250 working days per year, and the lead time is 5 days.

Holding cost for the parts is 0.3 dollars per unit per month and ordering cost is 40 dollars per order. Answer the following questions: Formulas: a) What is the EOQ? b) What are the costs previously (with 100 units per order) and now with EOQ. Hint: Calculate total holding cost and ordering cost for 100 units, and then same costs with EOQ. Which one (100 units or EOQ) is better in terms of costs?
