Average Total Cost Curve, a graph that shows the cost per unit of output produced, plotted against the quantity of output.

Economies Of Scale

Cost advantages reaped by companies when production becomes efficient, resulting in a decrease in the per-unit cost as the output increases.

AVC

Average Variable Cost, which is the cost a company incurs to produce one additional unit of a product, excluding fixed costs.

ATC

Average Total Cost, the total cost of production divided by the number of units produced, often used in economics to analyze production efficiency.
