Definitions:

Economies of Scale

Refers to the cost advantage that arises with increased output of a product, leading to a reduction in the per-unit cost.

Marginal Cost

An alternative phrasing expressing the additional cost incurred from the production of the next unit of output.

Average Total Cost

The cost per unit is calculated by dividing the overall production cost by the quantity of units produced.

Average Variable Cost

The total variable cost divided by the quantity of output produced; it shows the variable cost per unit of output.
