Ceramic, Tile & Sanitaryware Manufacturing worked example

Kiln Firing Cost at 110% firing cost allocated to this lot: a worked example

This scenario runs the kiln firing cost calculation on the strong side: 110% firing cost allocated to this lot, with every other input held at its documented default. a ceramic plant needs to estimate the firing cost assigned to a tile batch, sanitaryware lot, rework load, or customer quote

The inputs for this scenario

  • Fired tiles or sanitaryware pieces in the load: 18,000 pieces (unchanged)
  • Kiln firing cost per fired piece: 0.42 $ / piece (unchanged)
  • Firing cost allocated to this lot: 110 % (raised for this scenario; the documented default is 100)
  • Fixed kiln setup, car loading, or recipe-change cost: 850 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Allocated variable firing cost = fired pieces × kiln firing cost per piece × lot allocation) to the inputs above produces each figure below.
  • At this operating point the engine returns 9,166 $ firing cost for total kiln firing cost, the number this scenario is built around.
  • At this operating point the engine returns 0.51 $ / piece for firing cost per fired piece.
  • At this operating point the engine returns 8,316 $ for allocated variable firing cost.
  • At this operating point the engine returns 850 $ for fixed kiln setup and loading cost.

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 8.99% above the baseline at 9,166 $ firing cost.
  • Use it when quoting a firing job, costing a production lot, or testing whether a partial kiln load is economically justified. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Total kiln firing cost: 9,166 $ firing cost (headline result)
  • Firing cost per fired piece: 0.51 $ / piece
  • Allocated variable firing cost: 8,316 $
  • Fixed kiln setup and loading cost: 850 $
