Stock turnover ratio equals cost of
goods sold during a specific time frame, divided by the average stock holding
during the period.
The result of this ratio gives the "number of days that on average
money is tied up in stocks". The longer this is, obviously the worse this
is for the business as the money is not available to be used elsewhere. .
An stock turnover ratio of 20 means
that the average amount of stock holding during the year has been renewed, or
turned over, 20 times over the course of the year.
Dividing the number of days in the
period under consideration by the turnover ratio tells you how many days it
takes, on average, for the warehouse to empty and then be refilled. The number
of days in a year, 365, divided by 20 is 18.25. So the entire stock is fully
sold and replenished every 18.5 days, on average.
As a general rule, the higher the stock
turnover ratio, the more efficient and profitable the firm. A high ratio means
that the firm is holding a low level of average inventory in relation to sales.
Carrying stock ties up money. This
money is either borrowed and carries an interest charge, or represents funds that
could otherwise be better used in servicing other elements of the business.
There are additional costs in holding
stocks such as storage and the risk of getting spoiled, breaking, being stolen,
or simply going out of style.
Wherever possible companies need to
reduce stock holdings and there are various means by which to achieve this aim:
Liquidate slow-moving or obsolete
stocks.
Introduce more efficient production
techniques to reduce stock holdings.
Rationalise the product range weeding
out the under performers and thereby reduce stock carried.
Negotiate sale or return with suppliers
in order to avoid being stuck with unwanted product.
