How to Record Consumable Tooling and Molds as Factory Supplies Expensed Based on Production Volume
Capitalizing specialized molds and tooling as factory supplies and expensing them using the units-of-production method as they are consumed.
| Account Name | Type | Debit ($) | Credit ($) |
|---|---|---|---|
| Factory Supplies (Tooling) | Asset (+) | 2,000.00 | - |
| Accounts Payable | Liability (+) | - | 2,000.00 |
💡 Accountant's Note
Molds are 'prepaid' assets expensed into Overhead based on the number of units they produce (Units of Production method).
Practitioner & Systems Framework
💻 ERP Architecture
Production tooling (injection molds, stamping dies, cutting tools, jigs) has a finite useful life measured in production shots, strokes, or units — not calendar time. Capitalize the tooling cost as a Factory Supplies asset and expense through Manufacturing Overhead using the units-of-production method: Tooling Expense per unit = (Tooling Cost ÷ Expected Life in Units) × Units Produced in the period. This matches the tooling cost to the production volume it supports. Maintain a tooling register showing: tool ID, cost, expected life (shots), actual shots used, remaining life, and carrying value.
⚠️ Audit Flags
Auditors check that the expected tool life is based on engineering specifications or manufacturer data — not management estimates. Over-estimating tool life understates the monthly tooling expense. Physical inspection of tooling (comparing actual wear to the expected life schedule) confirms the amortization rate. Tooling that fails before its expected life creates an immediate write-off. Tooling purchased for a discontinued product must be immediately impaired (see manufacturing-specialized-tooling-impairment).
📄 Required Documentation
Tooling purchase invoice, engineering specification of expected tool life (in units), tooling register (tool ID, cost, expected life, shots used, carrying value), monthly units-of-production expense calculation, Manufacturing Overhead (Control) posting, physical tooling condition inspection, and tool life revision records.
