Problem # 5:
From the figures given below, calculate Economic Order Quantity (EOQ) and Total cost at EOQ?
Total consumption of material per year 10,000 kgs Buying cost per order Rs. 50
Unit cost of material Rs. 2 per kg Carrying and storage cost 8%
EOQ = 2,500 Units
Total Inventory Cost = [Fixed ordering cost (F) * Number of Order per year N] + [Carrying Cost (C)* EOQ/2]
Total Inventory Cost = [50 * 10,000/2,500] + [(2*0.08)* 2,500/2]
Total Inventory Cost = 200 + 200
Total Inventory Cost = Rs. 400
