absorption costing. a method of inventory costing in which all variable manufacturing costs and all fixed manufacturing costs are included as inventoriable costs.
Fixed costs are those that do not change as the level of output changes. Variable costs are those costs that change as output changes. Fixed costs can be quite large. In the airline industry, for example, fixed costs range from 40 to 70 percent of total costs.n our widget example, we will assume that the fixed cost for the stapler, pen, and âfactoryâ is $10 and the cost of each worker hired is $5 per worker. Since fixed costs are constant, the firm incurs $10 regardless of the level of output. Labor is the only variable cost computed by $5 times the number of workers.
