Step by step solution

Meaning of variable, fixed, and mixed cost

Term cost means the pecuniary value of any expenditure like raw material, labor, rent, etc. There are mainly three sorts of costs: variable, fixed, and mixed.

Variable costs rely upon the extent of production. It means variable costs increases when a rise within the units produced and vice versa.

Fixed costs don’t change because of changes in production level. These costs are incurred whether or not the production is zero.

Mixed costs have characteristics of variable similarly to fixed. Also referred to as semi-variable costs.
