Platinum and Iridium plugs perform at a lower level than copper spark plugs, because they are less conductive and they tend to overheat. However, the overall longevity of these two types of metal is better than copper plugs.
Carrying cost of inventory is often described as a percentage of the inventory value.This percentage could include taxes, employee costs, depreciation, insurance, cost to keep items in storage, opportunity cost, cost of insuring and replacing items, and cost of capital that help produce income for a business.Also referred to as inventory cost.his percentage could include taxes, employee costs, depreciation, insurance, cost to keep items in storage, opportunity cost, cost of insuring and replacing items, and cost of capital that help produce income for a business.

The sum gives you the formula for total inventory ordering and carrying costs. This formula assumes there is no discount for ordering items in bulk. Example: A business has an annual demand of 10,000 for a particular item. They order the item in batches of 1,000 and each order placement has a fixed cost of $120.The cost to hold an item in inventory is $0.80.Since we know D = 10000, Q = 1000, Fo = 120, and Fc = 0.8, we can compute the total cost:ach of these orders has a fixed cost of Fo, so the annual ordering cost is Fo*D/Q. The cost of holding an item in inventoy for a year is Fc and the average amount of inventery in stock is Q/2 (halfway between empty and full), thus the carrying cost is Fc*Q/2.
