Explanation : Operating ratios indicate the percentage of
sales that is absorbed to the cost of goods
sold and other operating expenses. It is the
test of operational efficiency with which the
business activities are being carried out. If the
ratio is lower, the position is favourable since
there is higher operating profit and the
management has succeeded in minimising the
operating costs. The higher operating ratio is
less favourable because it would leave only a
smaller margin of operating profit to meet the
obligation towards interest, income tax, and
dividend. There is no rule of thumb for this
ratio, because it varies from firm to firm
depending upon the nature of business. While
analysing this ratio, it is suggested that the
changes in operating ratios over a period of
time should be well analysed. The changes in
operating expenses can be either within the
control of management or beyond the control
of management. If the change in operating
expense is within the control of management,
appropriate steps can be taken to control the
same in forthcoming period, based on the
results and further probe.
