Pour Weight Calculator with pour-weight reduction project cost of 9,000 $: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop pour-weight reduction project cost to 9,000 $, then walk the calculation through step by step. Estimate the payback of a pour-weight reduction project such as gating redesign, riser optimization, simulation work, or pattern change.

The inputs for this scenario

  • Pour-weight reduction project cost: 9,000 $ (the input this scenario stresses; the baseline uses 18,000)
  • Annual metal saved from lighter pours: 42,000 $ / yr (held at the documented default)
  • Annual modeling and validation upkeep: 3,500 $ / yr (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Net annual pour weight calculator value = annual metal savings from lower pour weight - annual support and validation cost.
  • Pour Weight Calculator payback period works out to 0.23 yr at these inputs, and this is the headline figure for the scenario.
  • Net annual pour weight calculator value works out to 38,500 $ / yr at these inputs.
  • Pour-weight reduction project cost works out to 9,000 $ at these inputs.
  • Five-year net pour weight calculator value works out to 183,500 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where pour-weight reduction project cost sits at 18,000 $ and the headline result is 0.47 yr, this scenario comes in 50% below the baseline at 0.23 yr.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to pour-weight reduction project cost, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It assumes savings and support costs stay flat year over year; scrap rises, alloy switches, or volume swings can move both, so revisit the inputs annually.
