The Council On State Taxation (COST) is the premier state tax organization representing taxpayers. COST is a nonprofit trade association consisting of more than 600 multistate corporations engaged in interstate and international business. COST's objective is to preserve and promote equitable and nondiscriminatory state and local taxation of multijurisdictional business entities.
The average cost is the total cost divided by the number of goods produced. It is also equal to the sum of average variable costs and average fixed costs. Average cost can be influenced by the time period for production (increasing production may be expensive or impossible in the short run).
