itsual Cost Accounting
Overview
Cost accounting assigns costs to products, services, or activities so leaders can price, prioritize, and improve profitability with facts.
When to Use
- Product or SKU margin analysis
- Overhead allocation design
- Make-vs-buy decisions
- Cost reduction prioritization
Core Practices
- Distinguish direct vs indirect costs
- Choose allocation bases that reflect causality where possible
- Understand absorption vs variable costing impacts
- Review cost standards and variances in manufacturing contexts
- Refresh allocations as the business mix changes
Principles
- All allocation methods are imperfect — be transparent
- Decision-relevant cost may differ from full absorption cost
- Precision on immaterial allocations wastes time
- Operational partners must trust the cost model enough to use it
Verification
- Cost objects and direct costs are clear
- Allocation logic is documented
- Margin reports are used in decisions
