In economics, average variable cost (AVC) is a firm's variable costs (VC; labour, electricity, etc.) divided by the quantity of output produced (Q): = Average variable cost plus average fixed cost equals average total cost (ATC): A V C + A F C = A T C . {\displaystyle AVC+AFC=ATC.}
AVC is the Average Variable Cost, AFC the Average Fixed Cost, and MC the marginal cost curve crossing the minimum of both the Average Variable Cost curve and the Average Cost curve. Average variable cost (AVC/SRAVC) (which is a short-run concept) is the variable cost (typically labor cost) per unit of output: SRAVC = wL / Q where w is the wage ...
1. The Average Fixed Cost curve (AFC) starts from a height and goes on declining continuously as production increases. 2. The Average Variable Cost curve, Average Cost curve and the Marginal Cost curve start from a height, reach the minimum points, then rise sharply and continuously. 3. The Average Fixed Cost curve approaches zero asymptotically.
Total cost in economics includes the total opportunity cost (benefits received from the next-best alternative) of each factor of production as part of its fixed or variable costs. The additional total cost of one additional unit of production is called marginal cost. The marginal cost can also be calculated by finding the derivative of total ...
The average fixed cost function continuously declines as production increases. [7] Average variable cost (A.V.C) = variable costs divided by output. AVC =TVC/q. The average variable cost curve is typically U-shaped. It lies below the average cost curve and generally has the same shape - the vertical distance between the average cost curve and ...
Then its variable cost function is Q 3 –5Q 2 +60Q, and its average variable cost function is (Q 3 –5Q 2 +60Q)/Q= Q 2 –5Q + 60. The slope of the average variable cost curve is the derivative of the latter, namely 2Q – 5. Equating this to zero to find the minimum gives Q = 2.5, at which level of output average variable cost is 53.75.
The level of variable cost is influenced by many factors, such as fixed cost, duration of project, uncertainty and discount rate. An analytical formula of variable cost as a function of these factors has been derived. It can be used to assess how different factors impact variable cost and total return in an investment. [5]
Technically the supply curve is a discontinuous function composed of the segment of the curve at and above minimum of the average variable cost curve and a segment that runs on the vertical axis from the origin to but not including a point at the height of the minimum average variable cost.
