In: Accounting
Suppose that the annual demand for a componet is aproximately 60,000 units. The company ordes the component from a supplier who has offered the following quantity discount shedule.
order Quantity Price per unit
0-999 $30
1,000-1,999 $29
2,000-3,999 $28
4,000-or more $27
If the company's carrying charges is 15 percent of the item's price and the cost per order is $150, determine yhe order quantity that would minimize the total related inventory cost for this component.
Demand (D)= | 60,000 | units | ||||||||||||||||||||||||||||||
Quantity(Q) |
Price(P) | |||||||||||||||||||||||||||||||
0-999 | $ 30 | |||||||||||||||||||||||||||||||
1,000-1,999 | $ 29 | |||||||||||||||||||||||||||||||
2,000-3,999 | $ 28 | |||||||||||||||||||||||||||||||
4,000-or more | $ 27 | |||||||||||||||||||||||||||||||
Carrying cost | 15% | |||||||||||||||||||||||||||||||
Cost per order | $ 150 | |||||||||||||||||||||||||||||||
Calculating EOQ + Validity of order quantity with context to the above quantity discount schedule |
||||||||||||||||||||||||||||||||
Economic order quantity (EOQ) = square root of [(2 x demand x ordering costs) ÷ carrying costs] | ||||||||||||||||||||||||||||||||
EOQ(@$30 price) | 2,000 | ( valid EOQ 999) | ||||||||||||||||||||||||||||||
EOQ(@$29 price) | 2,034 | (Valid EOQ 1999) | ||||||||||||||||||||||||||||||
EOQ(@$28 price) | 2,070 | (Valid EOQ 2070) | ||||||||||||||||||||||||||||||
EOQ(@$27 price) | 2,108 |

Hence, the order quantity that would minimize the total related inventory cost for this component would be 4000 units.
