reasons, forecasting of demands of various products, abnormal situations like strikes, other

economic conditions and different Government policies.

Inventory Costs

Once inventory levels have been established, they become an important input to the budgeting system. Inventory decisions involve a delicate balance between three classes of costs:

1. Ordering costs2. Holding costs3. Shortage costs

7

Examples of Inventory Costs

Ordering costs : Time spent in finding suppliers and expediting orders, Clerical costs of preparing purchase orders, unloading and inspection costs.

Holding costs: Costs of storage space, Security, Insurance

Shortage costs: Lost sales and dissatisfied customers, Loss of quantity discounts on purchases, Idle workers.

EOQ model of Inventory management

EOQ refers to the quantity to be purchased every time so as to minimize the ordering and holding costs.

EOQ = 2AO/ C For Taylor Corporation, A = Annual demand = 4500 units O = Ordering cost per order = $60 C = Holding cost per unit per annum = $60 *

*( C = $ 1200* 5% = $60)

9

Computation of EOQ for Taylor Corporation

So EOQ = 2 x 4,500 x 6060

= 95 unitsAnnual demands = 4,500 unitsPer order = 95 unitsSo number of orders per annum will be =4,500/95 = 47.37 = 48 orders.So the Taylor Corporation has to

purchase 95 units of distance measuring devices per order as per EOQ.
