Ceramic, Tile & Sanitaryware Manufacturing worked example

Kiln Firing Cost at 72% firing cost allocated to this lot: a worked example

Suppose firing cost allocated to this lot falls to 72%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate firing cost for ceramic tile, porcelain, and sanitaryware loads using fired pieces, kiln cost per piece, yield scope, and fixed setup cost.

The inputs for this scenario

  • Fired tiles or sanitaryware pieces in the load: 18,000 pieces (held at the documented default)
  • Kiln firing cost per fired piece: 0.42 $ / piece (held at the documented default)
  • Firing cost allocated to this lot: 72 % (the input this scenario stresses; the baseline uses 100)
  • Fixed kiln setup, car loading, or recipe-change cost: 850 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Allocated variable firing cost = fired pieces × kiln firing cost per piece × lot allocation.
  • Total kiln firing cost works out to 6,293 $ firing cost at these inputs, and this is the headline figure for the scenario.
  • Firing cost per fired piece works out to 0.35 $ / piece at these inputs.
  • Allocated variable firing cost works out to 5,443 $ at these inputs.
  • Fixed kiln setup and loading cost works out to 850 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where firing cost allocated to this lot sits at 100% and the headline result is 8,410 $ firing cost, this scenario comes in 25.17% below the baseline at 6,293 $ firing cost.
  • It computes the total kiln firing cost for a lot by adding the allocated variable per-piece firing cost to the fixed setup, loading, and recipe-change cost. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • Total kiln firing cost: 6,293 $ firing cost (headline result)
  • Firing cost per fired piece: 0.35 $ / piece
  • Allocated variable firing cost: 5,443 $
  • Fixed kiln setup and loading cost: 850 $
