Definitions:

Average Total Cost

The total cost per unit of output, calculated by dividing the total cost of production by the total quantity produced.

Average Variable Cost

The variable cost (e.g., labor, materials) per unit of output, calculated by dividing total variable costs by the number of units produced.

Average Total Cost Curve

A graphical representation showing how the cost per unit of producing a good changes with the level of output.

Marginal Cost

The increase in cost that arises from producing one additional unit of a product or service.
