Relative to the ABC system, the simple costing system overcosts standard jobs and undercosts special jobs. Both types of jobs need 10 machine hours per job, so in the simple system, they are each allocated $335.83 in indirect costs. But, the ABC study reveals that each standard job consumes less of the indirect resources such as setups, purchase orders, and design costs than a special job, and this is reflected in the lower indirect costs allocated to the standard jobs and higher indirect costs allocated to special jobs in the ABC system.
