The Current Procedural Terminology book contains medical codes that are often called CPT codes or National Level I codes. These CPT codes depict procedures and services that can be performed by physicians, surgeons, specialists, and ancillary staff.
Formula of Variable Cost. The formula to calculate variable cost is: Total Variable Cost = Total Quantity of Output * Variable Cost Per Unit of Output. To recognize variable costs, it is important to understand how to categorize costs.Variable costs are those which do not remain constant, specifically when production activities fluctuate.ormula of Variable Cost. The formula to calculate variable cost is: Total Variable Cost = Total Quantity of Output * Variable Cost Per Unit of Output. To recognize variable costs, it is important to understand how to categorize costs.
If one assumes that the unit variable cost is constant, as in cost-volume-profit analysis developed and used in cost accounting by the accountants, then total cost is linear in volume, and given by: total cost = fixed costs + unit variable cost * amount.ne can decompose total costs as the sum of fixed costs and variable costs. In the Cost-Volume-Profit Analysis model, total costs are linear in volume. The total cost curve, if non-linear, can represent increasing and diminishing marginal returns.
