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.
