Costs, when categorized follow to habits (in relationship to transforms in level of activity), deserve to be divide into: (1) addressed costs and (2) change costs.

You are watching: If the level of activity increases within the relevant range:

Total variable expenses increase as number of units (cost driver) increase. Variable prices per unit are constant.

Within a relevant range, total fixed expenses are consistent even if systems increase. Fixed price per unit decreases as devices increase.

Mixed expenses have elements of both fixed and variable costs. For far better analysis that costs, mixed prices are often segregated right into variable and also fixed.

## Variable Costs

Within the relevant variety and mentioned time period, the total amount that variable costs varies directly (in proportion) to change in task level. The expense per unit is constant.000

For example: ABC firm spends \$2.50 materials price for every unit that Product A. If the agency produces 1,000 units, it spends \$2,500 (\$2.50 x 1,000). If that produces 2,000 units, climate the firm will spend \$5,000 (\$2.50 x 2,000). Take keep in mind that the cost per unit does not change but the total cost varies directly with the level the activity.

Total variable price = Variable price per unit x number of units or activity

Common instances of variable expenses include direct materials, direct labor, supplies, fuel and also power, spoilage costs, receiving costs, royalties, overtime premium, sales commissions, and also delivery expenses.

## Fixed Costs

Within the pertinent range, full fixed prices remain constant. Nevertheless of the level of activity, the business pays the same. However, the fixed cost per unit transforms as the level of task changes. As an ext units space produced, the fixed expense per unit decreases.

For example: ABC agency pays monthly rent of \$30,000 because that a factory building. Regardless of how plenty of units space produced, the firm pays the exact same amount. If we space to compute for the fixed cost per unit in ~ 1,000 units, it would be same to \$30 (\$3,000/1,000 units). If the company produces 1,500 units, climate fixed price per unit would be \$20 (\$3,000/1,500 units). As the level of task increases, the fixed price per unit decreases. The complete fixed expense remains the same.

Examples that fixed costs include rent, depreciation, patent amortization, home insurance, home taxes, and fixed incomes of manufacturing executives and also indirect labor.

## Mixed Costs

Mixed expenses contain both fixed and variable elements. The firm pays a constant fixed cost and a change amount on optimal of it. Instances of mixed prices include: utilities, repairs and also maintenance, inspection, fringe benefits, employer's payroll taxes, and salaries that contain a fixed amount add to commissions.

Total cost = Fixed costs + variable costsTotal expense = FC + (VC every unit x number of units)

## Example

XYZ company has gotten in into several contracts that need it come pay addressed selling expenses of \$100,000 per month. The cost accountant figured out the change selling cost at \$30 every unit. Compute because that the complete selling price that would certainly be occurs if the company expects to market 2,500 units next month.

Solution:Total cost = Fixed expense + change costsTotal price = \$100,000 + (\$30 x 2,500)Total expense = \$175,000
