Foundry & Forging calculator
Casting Yield Calculator
Measure how much poured metal becomes accepted casting weight and compare it with your yield target.
What this calculator does
- Measure how much poured metal becomes accepted casting weight and compare it with your yield target.
Formula used
- Casting yield = accepted casting weight ÷ metal poured × 100
- Target gap = target yield − casting yield
- Other metal = metal poured − accepted casting weight
- Target accepted weight = metal poured × target yield ÷ 100
- Additional accepted weight = max(0, target accepted weight − accepted casting weight)
Inputs explained
- Accepted Casting Weight: Matched lot weight after cutoff, cleaning and acceptance.
- Metal Poured: Total metal poured for the same lot, including rigging.
- Target Casting Yield: Yield target from the job routing or improvement plan.
How to use the result
- Best suited to a lower yield target is Met, a higher yield target needs more castings.
- This mass yield does not measure internal soundness or predict future rejection.
Current U.S. benchmarks
- The producer price index for steel mill products stands at 381.162 (BLS, Aug 2026), up 23.4% from a year earlier. Quotes priced off last quarter's material cost miss this move.
- The U.S. has 3,569 primary metal manufacturing establishments employing about 354,911 workers (Census County Business Patterns, 2023).
Common questions
- Can I enter casting counts? Use measured weights here. Counts would ignore differences in casting size and rigging mass.
- Do returned risers count as loss? They reduce this pour yield even if you remelt them. They are not necessarily an unrecoverable metal loss.
- What target should I enter? Use the target approved for this part and casting method. No universal yield target is assumed.
- Why can accepted weight not exceed poured weight? Both measurements must cover the same lot. A larger accepted weight indicates mismatched records or units.
