Industrial Enzymes & Bio-Ingredients worked example
Batch Failure Cost at 54% rejected or downgraded batch share: a worked example in industrial enzymes & bio-ingredients
Suppose rejected or downgraded batch share falls to 54%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate the cost exposure from a failed or rejected enzyme or bio-ingredient batch using batch size, cost per kg, affected share, and fixed investigation costs.
The inputs for this scenario
- Finished or in-process batch size: 5,200 kg (held at the documented default)
- Enzyme cost per kg or activity basis: 16 $ / kg (held at the documented default)
- Rejected or downgraded batch share: 54 % (the input this scenario stresses; the baseline uses 75)
- Fixed investigation and disposal cost: 18,000 $ (held at the documented default)
Working through the calculation
- The calculation starts from the formula this tool documents: Variable batch failure cost = finished or in-process batch size × cost per kg or activity basis × rejected or downgraded batch share.
- Total batch failure cost works out to 62,928 $ at these inputs, and this is the headline figure for the scenario.
- Cost per kg or activity basis works out to 12.1 $ / kg at these inputs.
- Variable batch failure cost works out to 44,928 $ at these inputs.
- Fixed investigation and disposal cost works out to 18,000 $ at these inputs.
How this compares with the baseline
- Against the tool's baseline example, where rejected or downgraded batch share sits at 75% and the headline result is 80,400 $, this scenario comes in 21.73% below the baseline at 62,928 $.
- It computes the total financial loss of a failed enzyme batch by adding the value of rejected or downgraded material to fixed investigation and disposal costs. 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.
