Total cost (TC) is the term used in economics to describe the lowest possible cost of producing a certain amount of product.
The total economic cost of production is comprised of two components variable cost, which varies depending on the amount of a good produced and includes inputs like labor and raw materials, and fixed cost, which is separate of the amount of a product generated and includes inputs like buildings and machinery that cannot be changed in the brief term, conceivably including sunk costs.
The marginal cost, or the price of producing more, is the adjustment to the overall cost in economics that results from increasing the quantity produced.
