Now the team can pute the individual activity rates by dividing the total cost for each activity by the total activity levels Step 4: Calculate Activity Rates After the firststage allocation is plete, putation of activity rates for each activity cost pool can be done as follows: C om put a t i on of t he A c t i v i t y R a t e s C us t om e r O r de r s P r odu c t D e s i gn O r de r S i z e C us t om e r R e l a t i ons O t he r C os t s f r om f i r s t s t a ge a l l oc a t i on 3 1 5 , 0 0 0$ 2 5 7 , 0 0 0$ 3 8 0 , 0 0 0$ 3 6 7 , 5 0 0$ 4 9 0 , 5 0 0$ Tot a l a c t i v i t y 1 , 0 0 0 200 2 0 , 0 0 0 100 N / AC os t pe r uni t of a c t i v i t y 315$ 1 , 2 8 5$ 19$ 3 , 6 7 5$ pe r or de r pe r de s i gn pe r M H pe r c us t . pe r M H pe r c us t om e r .247。 247。 247。 it is not assigned to products.

Under ABC both manufacturing and nonmanufacturing costs may be assigned to products. Organizationsustaining costs and the costs of idle capacity are not assigned to products. Activitybased versus conventional product costs ? Conventional costing assumes product costs are driven by volumebased cost drivers ? Conventional costing ignores batch size units produced in large batches consume a relatively low amount per unit of batch costs ? ABC can include nonmanufacturing costs ABC benefits will be greatest where... ? Overhead costs are a significant proportion of total cost, and a large part of overhead is not directly related to production volume ? The business has a diverse product range, and the individual products? use of support resources differs from their use of volumebased cost drivers ABC benefits will be greatest where... ? Production activity involves diverse batch sizes and product plexity. ? There are likely to be high ?costs? associated with making inappropriate decisions, based on inaccurate product costs. ? The cost of designing, implementing and maintaining an ABC system is relatively low due to sophisticated IT support Impediments to introducing ABC ? Lack of awareness of ABC ? Uncertainty about the potential benefits from ABC ? Firms understand the need for change but are concerned about the extensive resource requirements to implement ABC ?
