THE NUMBERS, EXPLAINED
How to use this calculator.
One closed batch boundary; incoming rework belongs in ingredient inputs. Does not infer lot identity from totals.
Start with your inputs
Enter ingredient lot masses entering batch (kg), finished output mass (kg), rework transferred out (kg), recorded processing loss (kg). Keep amounts in the units shown on each field. The example is a starting point, not a recommended value.
| Input | Example value |
|---|---|
| Ingredient lot masses entering batch (kg) | 80,20 |
| Finished output mass (kg) | 85 |
| Rework transferred out (kg) | 5 |
| Recorded processing loss (kg) | 8 |
A worked example
With the example inputs above, input mass (kg) is 100. Change the inputs to explore your own scenario.
| Result | Example answer |
|---|---|
| Input mass (kg) | 100 |
| Unreconciled mass (kg) | 2 |
| Finished yield (%) | 85 |
How this is calculated
Input mass (kg)
Add ingredient lots entering the batch.
Unreconciled mass (kg)
Subtract finished output, outgoing rework and known losses.
Finished yield (%)
Divide finished product by ingredient input mass.
Symbols and units
- a
- Ingredient lot masses entering batch (kg)
- b
- Finished output mass (kg)
- c
- Rework transferred out (kg)
- d
- Recorded processing loss (kg)
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions and limits
One closed batch boundary; incoming rework belongs in ingredient inputs. Does not infer lot identity from totals.
Calculations use the values you enter. Blank or invalid inputs show an error instead of silently substituting zero. Results are displayed to useful precision; calculations retain the underlying numeric precision.
Questions about this tool
What does the result tell me?
Input mass (kg); Unreconciled mass (kg); Finished yield (%). The result applies to the method and inputs described above. Check the units and assumptions before using it in a decision.
Why might another calculator differ?
Differences in units, rounding, timing or model definitions can produce different answers. Compare the input definitions and the method, rather than only the final number. For this tool: One closed batch boundary; incoming rework belongs in ingredient inputs. Does not infer lot identity from totals.
Are my inputs stored or sent to AI?
Calculations on this page happen in your browser. The separate AI question finder sends its submitted conversation to OpenAI; these calculator fields are not sent. Favourites and recent tool names are stored locally. A shared link contains the inputs you choose to include.
