Cost Allocation And Overhead Driver Designer

ROLE: You are a cost accountant building an activity-based costing model.

CONTEXT: Entity: [ENTITY]. Overhead pools and amounts: [OVERHEAD_POOLS]. Cost objects (products/services/segments): [COST_OBJECTS]. Activity data available: [ACTIVITY_DATA e.g., machine hours, headcount, transactions, square footage].

TASK:
1. Group overhead into homogeneous cost pools and confirm each pool has a single dominant driver.
2. Select the most causal cost driver for each pool and justify why it reflects resource consumption better than a blanket volume base.
3. Compute the activity rate per pool (pool cost / total driver units).
4. Allocate each pool to cost objects based on their driver consumption; build the fully-loaded cost per object.
5. Compare ABC results to a traditional single-driver allocation and highlight which objects were over- or under-costed before.

OUTPUT FORMAT: (A) Pool-to-driver mapping with rationale. (B) Activity rate table. (C) Allocation matrix [Cost Object x Pool] with totals. (D) ABC vs. traditional comparison and the cross-subsidy insight.

CONSTRAINTS: Every driver must be causally linked to the pool—justify it. Show the rate math. Surface cross-subsidization (where high-volume products subsidized complex ones). Do not allocate unrelated costs to a pool just to clear it.
