Foundry & Forging calculator
Pattern Cost Amortization Calculator
Allocate pattern, core box, matchplate, tooling, or gating-revision cost across castings. Use it when a new pattern, pattern repair, core box, rigging change, or customer revision must be recovered in part pricing.
What this calculator does
- Allocate pattern, core box, matchplate, tooling, or gating-revision cost across castings.
- Use it when a new pattern, pattern repair, core box, rigging change, or customer revision must be recovered in part pricing.
- Allocates pattern/tooling cost to castings.
Formula used
- Total pattern cost amortization = castings covered by pattern cost × pattern cost per covered casting × pattern cost allocation + fixed pattern engineering cost
- Pattern cost per casting = total cost ÷ castings covered by pattern cost
Inputs explained
- Castings covered by pattern cost: Enter forecast quantity, order quantity, or life-of-tool castings covered by the pattern or core box.
- Pattern cost per covered casting: Use amortized pattern, core box, matchplate, rigging, or tooling cost per casting.
- Pattern cost allocation: Enter the share assigned to this customer, part number, revision, or quote.
- Fixed pattern engineering cost: Add design, CAD, simulation, gating layout, sampling, storage, or maintenance cost.
How to use the result
- Use during quoting and tooling review.
- This calculator is an estimating tool. Results can change with alloy chemistry, furnace practice, ladle losses, mold design, gating and riser layout, core condition, pattern allowance, die temperature, press condition, inspection criteria, rework rules, energy rates, labor standards, and actual shop performance. Validate safety-critical, metallurgical, tooling, press-capacity, and customer-spec decisions with qualified engineering, metallurgy, OEM data, and the applicable control plan.
Common questions
- What information do I need before using the Pattern Cost Amortization? Use covered casting quantity, amortized cost per casting, allocation percentage, and fixed pattern cost.
- What does the result mean? It estimates total pattern cost and pattern cost per casting.
- When is the result only an estimate? This calculator is an estimating tool. Results can change with alloy chemistry, furnace practice, ladle losses, mold design, gating and riser layout, core condition, pattern allowance, die temperature, press condition, inspection criteria, rework rules, energy rates, labor standards, and actual shop performance. Validate safety-critical, metallurgical, tooling, press-capacity, and customer-spec decisions with qualified engineering, metallurgy, OEM data, and the applicable control plan.
- What decision can I make from the result? Use it to quote tooling, set amortization charges, or compare customer-owned versus supplier-owned tooling.
