Foundry & Forging calculator
Casting Lot Cost Calculator
Estimate total cost for a casting lot including metal, molding, cores, melt, cleaning, inspection, rework, and fixed setup cost. Use it when quoting a lot, comparing suppliers, setting minimum order quantities, or reviewing actual cost versus estimate.
What this calculator does
- Estimate total cost for a casting lot including metal, molding, cores, melt, cleaning, inspection, rework, and fixed setup cost.
- Use it when quoting a lot, comparing suppliers, setting minimum order quantities, or reviewing actual cost versus estimate.
- Builds a casting lot cost estimate.
Formula used
- Total casting lot cost = castings in the lot × variable cost per casting × lot cost allocation + fixed lot setup cost
- Cost per casting = total cost ÷ castings in the lot
Inputs explained
- Castings in the lot: Enter accepted castings, poured castings, or order quantity included in the lot estimate.
- Variable cost per casting: Use metal, mold, core, melt, pour, shakeout, cleaning, heat treat, machining allowance, and inspection cost per casting.
- Lot cost allocation: Enter the share of the lot included in this estimate or assigned to this customer/order.
- Fixed lot setup cost: Add pattern setup, mold setup, core box setup, first article, lab testing, freight, or documentation cost.
How to use the result
- Use for estimating and purchasing.
- 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 Casting Lot Cost? Use casting count, variable cost per casting, allocation percentage, and fixed setup cost.
- What does the result mean? It estimates total casting lot cost and 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 lots, compare supplier bids, set MOQs, and review profitability.
