Inventory can be defined as good or
materials that have been held in stock by a company in order to
meet the requirements of its customers. The sole reason for holding
inventory is the smooth functioning of the business. Carrying
materials in inventory involves huge costs and expenses but if a
company does not have proper inventory levels they might have to
suffer on their sales volume and business can be interrupted,
therefore it is very important to have right balance of inventory
in an organization.
Inventory carrying costs can be
classified into following major elements:
- Interest charged:
Many businesses these days are backed up by funding from banks or
investors and they charge hefty interests on the funding raised.
The large part of that funding is then converted into inventory by
the companies to meet the customer's demands. Therefore, that
interest being charged is one of the elements of these costs
because after all that funding was converted into inventory.
- Storage costs:
Once the inventory is purchased by the company that inventory needs
to be properly procured, managed and stored and for that companies
either buy or rent warehouses and other storage spaces. The
combination of warehouse rent, mortgage, lighting expenses, air
conditioning etc forms another element of carrying inventory costs.
Some of the costs are fixed in nature like rent of warehouse and
some of them are variable like handling costs.
- Taxes paid and insurance
covering inventory: Another element of carrying inventory
costs includes taxes paid to the local government or local body and
insurance paid to insure the inventory from fire, theft or damage.
As the level of inventory is high it becomes very important to have
insurance, otherwise firms might have to incur severe losses due to
lack of insurance cover. The premium of the insurance varies
according to the level and type of inventory; higher the level of
inventory, higher is the amount of insurance premium.
- Personnel and machinery
cost: For carrying materials in inventory companies need
various kinds of machinery and people to handle that inventory.
Machinery can vary from loading vehicles to mini trucks which again
involve cost to run and manage the machines. Similarly various
kinds of personnel like Computer operators, data entry operators,
mechanics and engineers are required to operate those machines and
handle the inventory. Therefore these personnel and machinery cost
forms another element of inventory carrying costs.
- Inventory risk
costs: Carrying or storing materials in inventory comes
with a certain amount of risk. Insurance can provide cover for
theft or fire or water damage but still there are risks which
cannot be insured. When a company stocks a certain type of goods
there is always a fear or risk that item may fall in real value
during the period it is in the warehouse. New version or new
products can suppress the products stored in warehouses which are
later sold on too low prices which is a loss for the company. In
case of some items like medicines or perishable goods which come
with an expiry date, such risk increases and if the items expire
than they are mostly scrapped. Hence these type of costs is an
another element which makes up inventory carrying costs.
