What is 'Economies Of Scale'

Economies of scale is the cost advantage that arises with increased output of a product. Economies of scale arise because of the inverse relationship between the quantity produced and per-unit fixed costs; i.e. the greater the quantity of a good produced, the lower the per-unit fixed cost because these costs are spread out over a larger number of goods. Economies of scale may also reduce variable costs per unit because of operational efficiencies and synergies. Economies of scale can be classified into two main types: Internal – arising from within the company; and External – arising from extraneous factors such as industry size.
