Product Cost Analyzer

Problem

Cost review often fails not because totals are unavailable, but because direct materials, packaging, manufacturing overhead, admin costs, freight, and tax are mixed into one number. The product-cost-analyzer skill gives a structured view for a single product or a batch. For quote review, loss analysis, and unit-cost variation, this structure is more useful than a single total.

How It Works

The skill separates inputs into cost categories:
- Direct costs: raw_material, packaging
- Manufacturing overhead: labor, depreciation, utilities, maintenance, and consumables inside manufacturing
- Indirect costs: admin_expense, freight, tax

It calculates total_cost, derives unit_cost from quantity, and returns cost_breakdown plus percentage_breakdown. The percentage view makes it easier to compare cost drivers and identify large items.

Boundaries

This is useful for full-cost accounting where manufacturing subitems need to be visible. Defaults are 0, but quantity must be greater than 0. It does not infer accounting treatment, validate tax rules, or replace financial audit; callers must ensure the input amounts and category mappings are correct. If the same product shows cost variation across batches, record inputs for each run and compare outputs. The output is suitable for tables or cost-review notes.
