Definition. The Average Variable Cost (AVC) is the total variable cost per unit of output. This is found by dividing Total Variable Cost (TVC) by total output (Q). Total Variable Cost (TVC) is all the costs that vary with output, such as materials and labor.he average variable cost is a firm's variable cost per unit of output. Most AVC functions will start decreasing and then at one point, begin to increase. A firm will chose to shut down production in the short run if the market price is less than the average variable cost of production.
