Variable Cost per Unit. If the number of units produced in the period is 1,000 then the variable cost per unit is calculated as follows. Variable cost/unit = Variable cost / Number of units Variable cost/unit = 92,600 / 1,000 Variable cost/unit = 92.60.
Variable Costs: Variable costs change in direct proportion to the level of production. This means that total variable cost increase when more units are produced and decreases when less units are produced.Although variable in total, these costs are constant per unit.ixed costs are those which do not change with the level of activity within the relevant range. These costs will incur even if no units are produced. For example rent expense, straight-line depreciation expense, etc. Fixed cost per unit decreases with increase in production.
