Sales commission is a variable cost because the amount of the account is subject to variation. Think about it: A used car salesman is paid a commission say of $500 for every car he sells for the month of October. If he sells only 2 cars, then the sales commission is $1000, If he sells a whopping 12 cars, then the sales commission is $6000!!
It was to meet this need that direct costing was developed. Direct costing, sometimes called variable costing, is based on the classification of costs as variable and fixed. Variable costs are defined as those costs that vary in relation to the changes in the volume of production.
