35 calculate Activity-Based Product Costs

As modern technology changes the ratio in between direct labor and also overhead, an ext overhead costs are connected to vehicle drivers other than direct labor and an equipment hours. This shift in expenses gives service providers the chance to stop using the traditional single predetermined overhead rate applied to all devices of production and also instead use an overhead allocation strategy based ~ above the actual activities that drive overhead. Make this change allows administration to obtain more accurate product cost information, which leads to an ext informed decisions. Activity-based costing (ABC) is the process that assigns overhead come products based on the various tasks that journey overhead costs.

You are watching: The labor time required to assemble a product is an example of a:

Historical perspective on decision of production Overhead Allocation

All products consist of material, labor, and overhead, and the significant cost contents have historically been materials and labor. Manufacturing overhead was not a large cost of the product, for this reason an overhead allocation an approach based on labor or maker hours to be logical. For example, as presented in (Figure), Musicality identified the straight costs and also direct job for their 3 products: Solo, Band, and Orchestra. Under the traditional technique of costing, the predetermined overhead rate of $2 per straight labor hour to be computed by separating the approximated overhead by the estimated direct labor hours. Based upon the variety of direct labor hours and the number of units created for each product, the overhead per product is presented in (Figure).

As technology costs decreased and also production techniques became more efficient, overhead costs changed and ended up being a much bigger component that product costs. For many companies, and also in plenty of cases, overhead prices are now significantly larger 보다 labor costs. Because that example, in the last few years, numerous industries have actually increased technology, and also the lot of overhead has actually doubled.1 an innovation has readjusted the production labor force, and therefore, the kind and expense of labor linked with those jobs have changed. In addition, technology has do it less complicated to monitor the various activities and their related overhead costs.


Once the prices are group into similar cost pools, the tasks in every pool room analyzed to determine which task “drives” the expenses in that pool, leading to the third step of ABC: recognize the price driver for each price pool and estimate an yearly level of activity for each price driver. Together you’ve learned, the cost driver is the particular activity the drives the expenses in the expense pools. (Figure) mirrors some tasks and cost drivers for those activities.

Activities and also Their typical Cost DriversCost PoolCost Driver
Customer orderNumber that orders
ProductionMachine setups
Purchasing materialsPurchase requisitions
Assembling productsDirect job hours
Inspecting productsInspection hours
Customer serviceNumber of contacts v customer

The fourth step is come compute the predetermined overhead price for each of the cost drivers. This part of the process is similar to detect the traditional predetermined overhead rate, where the overhead rate is separated by straight labor dollars, direct labor hours, or device hours. Each cost driver will have its very own overhead rate, i m sorry is why alphabet is a more accurate technique of allocation overhead.

Finally, step five is come allocate the overhead costs to each product. The predetermined overhead rate found in step four is used to the really level of the price driver provided by each product. As with the timeless overhead assignment method, the really overhead prices are gathered in an account referred to as manufacturing overhead and also then applied to each of the products in this step.

Notice that procedures one with three represent the process of allocating overhead costs to activities, and also steps four and also five stand for the process of allocation the overhead prices that have been assigned to activities to the products to which castle pertain. Thus, the five steps of alphabet involve two significant processes: first, allocating overhead prices to the various tasks to gain a expense per activity, and then allocating the expense per activity to every product based upon that product’s intake of the activities.

Now that the steps involved have been detailed, let’s show the calculations utilizing the Musicality example.

A agency has established that its approximated 500,000 maker hours is the optimal driver for its estimated $1,000,000 maker overhead cost pool. The $750,000 in the material overhead price pool need to be allocated making use of the estimated 15,000 product requisition requests. How much is over- or underapplied if there were actually 490,000 an equipment hours and 15,500 material requisitions that led to $950,000 in the device overhead price pool, and $780,000 in the material price pool? What walk this difference indicate?


The predetermined overhead rate is $2 per maker hour ($1,000,000/500,000 maker hours) and also $50 per material requisition ($750,000/15,000 requisitions). The actual and also applied overhead have the right to then it is in calculated to identify whether the is over- or underapplied:

Identify the price driver for each activity, and estimate an annual task for every driver. Musicality identified the driver and estimated activity for every product to be the following:
Allocate overhead costs to products. Presume Musicality’s tasks were together estimated, the amount allocated to each product is:

The overhead per unit can be included to the unit price for direct material and direct labor to compute the total product price per unit:


The loss on each sale the the Solo product was not discovered until the firm did the calculations because that the abc method, since the sales of the other assets were solid enough because that the company to retain a full gross profit.

Additionally, the more accurate gross profit for every product calculated utilizing ABC is presented in (Figure):


The calculations Musicality go in stimulate to switch to abc revealed the the Solo product was generating a loss for every unit sold. Knowing this details will enable Musicality to consider whether they have to make transforms to generate a profit from the Solo product, together as boost the selling price or carefully analyze the costs to determine potential cost reductions. Musicality could likewise decide to continue selling Solo at a loss, due to the fact that the other commodities are generating sufficient profit because that the agency to absorb the Solo product loss and also still be profitable. Why would a company continue to market a product the is generating a loss? periodically these commodities are ones because that which the agency is well known or that attract customers into the store. Because that example, providers will sometimes offer extreme sales, such as on black Friday, to attract customers in the hope that the customers will purchase other products. This information shows how beneficial ABC can be in many situations for giving a an ext accurate picture than timeless allocation.

The business Industries and Their usage of the Activity-Based Costing assignment Method

ABC costing was developed to aid management recognize manufacturing costs and also how they deserve to be better managed. However, the company industry can apply the same principles to enhance its expense management. Straight material and direct labor costs variety from missing to minimal in the company industry, which renders the overhead applications even an ext important. The number and types of price pools may be fully different in the company industry as contrasted to the production industry. Because that example, the health-care sector may have various overhead costs and cost chauffeurs for the treatment of illnesses 보다 they have actually for injuries. Several of the overhead regarded monitoring a patient’s wellness status might overlap, however most of the overhead related to diagnosis and treatment differ from every other.

Activity-based costing is not minimal to manufacturing. Company industries likewise have expense drivers and can benefit from evaluating what drives your costs. See this report on activity-based costing in ~ UPS for an example.
