Cost structure and the operating leverage factor
The concept cost structure refers to the relative relationship between fixed and variable costs in an
enterprise. During recent years the cost structure of manufacturing enterprises has changed in that costs have
become more fixed as a result of automation. More machines and less manual labour are used in production.
Enterprises with a high percentage fixed costs are more sensitive to changes in sales than enterprises with a
low percentage fixed costs. For example, consider a firm with relatively high fixed costs (ie, relatively low
variable costs and consequently a high profit-volume ratio). If sales should increase, profit will increase as a
higher rate than for a firm with relatively low fixed costs, because of the high profit-volume ratio. However,
if sales should drop, profit will also drop at a higher rate because, although variable costs will drop as well,
the fixed costs (rent, salaries, etc) must still be paid.
