Kiln Utilization Cost at 59% kiln load efficiency: a worked example

Suppose kiln load efficiency falls to 59%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate loaded kiln-hour value from usable kiln hours, cost per kiln hour, load efficiency, and fixed firing-cycle cost.

The inputs for this scenario

  • Usable kiln cycle hours: 28 kiln hr (held at the documented default)
  • Cost per kiln hour: 185 $ / kiln hr (held at the documented default)
  • Kiln load efficiency: 59 % (the input this scenario stresses; the baseline uses 82)
  • Fixed firing-cycle cost: 950 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Utilized kiln-hour value = usable kiln hours × cost per kiln hour × kiln load efficiency.
  • Loaded kiln utilization cost works out to 4,006 $ kiln cost at these inputs, and this is the headline figure for the scenario.
  • Cost per kiln hour works out to 143 $ / kiln hr at these inputs.
  • Utilized kiln-hour value works out to 3,056 $ kiln cost at these inputs.
  • Fixed firing-cycle cost works out to 950 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where kiln load efficiency sits at 82% and the headline result is 5,198 $ kiln cost, this scenario comes in 22.92% below the baseline at 4,006 $ kiln cost.
  • It computes the utilized value of a firing's kiln hours after load efficiency, then adds the fixed firing-cycle cost for a total loaded kiln 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

  • Loaded kiln utilization cost: 4,006 $ kiln cost (headline result)
  • Cost per kiln hour: 143 $ / kiln hr
  • Utilized kiln-hour value: 3,056 $ kiln cost
  • Fixed firing-cycle cost: 950 $
