What a finished ACC-650 Topic 3 activity based costing analysis looks like
The finished example produces a reversal rather than describing one. The same product set is costed under a plantwide rate and then under activity pools with drivers, and the low volume complex product turns out to have been subsidized by the high volume simple one, which is the pattern the method exists to reveal. Each activity pool is named with the driver that causes its cost, and the example is careful that a driver has to cause the cost rather than merely correlate with volume. The implementation cost is addressed honestly, since activity costing takes real effort to maintain and is not worth it everywhere. The decision consequences are drawn: pricing, product mix and where to look for cost reduction.
How an ACC-650 Topic 3 example is structured
The example costs twice and explains the difference. It opens with the product set and the total overhead to be assigned. A second section costs everything under a single plantwide rate, which is the current state in most firms. A third builds activity pools, naming each activity and the driver that causes its cost. A fourth recosts the products under those drivers and tabulates both results side by side. A fifth explains the difference, identifying which product was subsidizing which and why volume based allocation produced that. A sixth draws the decision consequences for pricing and product mix. A closing section weighs the cost of running the system against the value of the better information, since the answer is not always to adopt it.
Both costings shown side by side
The reversal only lands when the plantwide and activity based figures sit in the same table.
Drivers that cause, not correlate
A driver has to be what makes the cost happen, since a volume proxy reproduces the problem being fixed.
The cross subsidy named
Which product was carrying which, and why a volume based rate produced that transfer.
Decisions that change
Pricing, product mix and where to hunt for cost reduction all move once the true cost appears.
Implementation cost weighed
The system takes real effort to maintain, and the closing section says whether this firm should bother.
Where marks go in ACC-650 Topic 3
Describing activity costing without recosting anything defeats the assignment, since the entire argument depends on showing that the numbers actually move. A second weakness is drivers chosen that are really volume in disguise, which reproduces the plantwide result and demonstrates nothing. Papers lose marks for recommending adoption without weighing the maintenance burden, because the method is expensive to run and is genuinely not worth it in a single product operation. Failing to identify which product subsidized which leaves the analysis short of its finding. Recosting products and then drawing no pricing or mix consequences ends the paper before the decisions the numbers were computed for. Pools built without naming the activity that consumes them cannot be defended to anybody.

ACC-650 Topic 3 questions, answered
What makes a good cost driver?
Something that causes the cost to be incurred. Number of setups drives setup cost because each setup consumes the resource; number of units does not, because a thousand unit run and a ten unit run need one setup each. Testing whether the driver causes rather than merely accompanies the cost is what separates a real activity system from a relabeled volume allocation.
Why do low volume products come out more expensive?
Because they consume activities disproportionately to their volume. A product made in small batches needs as many setups, inspections and orders as one made in large batches, so it absorbs those costs on far fewer units. A volume based rate spreads them evenly and hides it, which is why the high volume product appears to cost more than it does and subsidizes the other.
Is activity based costing always worth adopting?
No, and saying so demonstrates judgment. It requires identifying activities, measuring drivers and maintaining the data, which is ongoing work. In a firm with one product, or where overhead is a small share of total cost, the plantwide rate is close enough and the effort is wasted. The case for adoption strengthens with product diversity and with overhead as a proportion of cost.
