Value Chain Margin Cocoon To Silk
Balance cocoon purchase, explicit conversion costs, silk yield and byproducts into a signed cocoon-to-silk contribution; excludes unspecified capital/tax charges.
Description
Cocoon conversion generates silk and possible byproducts while incurring purchase and processing costs.
Cocoon conversion generates silk and possible byproducts while incurring purchase and processing costs. Contribution is revenue less the explicitly included costs.
Balance cocoon purchase, explicit conversion costs, silk yield and byproducts into a signed cocoon-to-silk contribution; excludes unspecified capital/tax charges.
When to use Value Chain Margin Cocoon To Silk
Use this tool to balance cocoon purchase, explicit conversion costs, silk yield and byproducts into a signed cocoon-to-silk contribution; excludes unspecified capital/tax charges.
Prepare cocoon, larval, leaf or reeling measurements on a consistent batch and moisture basis. Use the declared mass, length and time units.
How to use Value Chain Margin Cocoon To Silk and understand its results
- Prepare cocoon, larval, leaf or reeling measurements on a consistent batch and moisture basis. Use the declared mass, length and time units.
- Enter cocoonInputKg, cocoonPricePerKg, rawSilkYieldFraction, rawSilkPricePerKg, byproductRevenue, conversionCosts using the field table and calculation rules, then run the tool.
- Read rawSilkOutputKg, totalRevenue, totalCost, chainContribution, contributionPerRawSilkKg. The explanation below defines the units, signs, ordering and any flags or placeholder values.
- If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.
| Input field | Meaning | Value type; see rules below | Requirement |
|---|---|---|---|
| cocoonInputKg | Cocoon input kg | number | Required |
| cocoonPricePerKg | Cocoon price per kg | number | Required |
| rawSilkYieldFraction | Raw silk yield fraction | number | Required |
| rawSilkPricePerKg | Raw silk price per kg | number | Required |
| byproductRevenue | Byproduct revenue | number | Required |
| conversionCosts | Conversion costs | list of number | Required |
Use positive cocoon kg and yield fraction in (0,1], nonnegative prices and revenues, and at least one explicit conversion cost. Calculate silk output, totals and signed contribution per silk kg.1
contribution = silk kg × silk price + byproduct revenue − cocoon purchase − conversion costs Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| rawSilkOutputKg | Raw silk output kg | number |
| totalRevenue | Total revenue | number |
| totalCost | Total cost | number |
| chainContribution | Chain contribution | number |
| contributionPerRawSilkKg | Contribution per raw silk kg | number |

}Limitations and assumptions
Unspecified capital charges, taxes and other costs are excluded; use one currency.
Numbers and computed results must be finite; overflow produces an error. Numeric lists are limited to 100,000 entries; the rules above may require smaller limits. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.
Alternative or Complementary methods
Use Reeling Labor Cost Per KG Silk: Allocate role-specific productive and additional paid downtime labor plus employer load to actual saleable silk kg; supplied productive hours must exclude the separate downtime. For a complementary task, use Raw Silk Recovery Percent: Balance raw-silk recovery on wet/dry bases and retained dry byproducts; unrecovered includes non-silk material and is not automatically pure-silk loss.
