FAQ

What this tool can do

See batch revenue, cost, and profit quickly.
Compare cocoon sales and silk conversion under the same assumptions.
Treat mortality as a signal for improvement, not just a loss number.
Bring it to the field with multilingual, multi-currency, and multi-unit support.

How to use

  1. Enter the basic values such as leaf amount, cocoon yield, and labor time.
  2. Choose the sales route and cocoon pricing conditions.
  3. Check revenue, cost, profit, and the gap in the result cards.
  4. Copy, share, export CSV, or print when needed.

Examples

Quick baseline example

Input

Use only leaf amount, cocoon yield, and labor time to get a first profit read.

Output

You can confirm the profit direction immediately using cocoon sales as the baseline.

Detailed grading example

Input

Enter grade ratios and unit prices to compare cocoon sales pricing.

Output

Changing detailed conditions shows how revenue moves even with the same cocoon yield.

Silk conversion example

Input

Enter reeling yield and silk price to compare the conversion route.

Output

You can compare the gap against cocoon sales after including reeling processing cost.

Glossary

Cocoon

The thread mass produced by silkworms. It is the weight basis for sales and reeling.

Grading

Separating cocoons by quality. Revenue is calculated from grade ratios and unit prices.

Reeling yield

The percentage of silk obtained when cocoons are converted into raw silk.

Mortality rate

The share lost during rearing. It helps evaluate actual results and room for improvement.

Labor time

The working time used for rearing. It is converted into daily and hourly efficiency.

Leaf amount

The amount of mulberry leaf used for rearing. It is a key cost base.

Cocoon yield

The amount of cocoon collected in one batch. It is the base for revenue calculation.

Break-even point

The price or amount at which profit becomes zero.

Formulas

  • Cocoon sales revenue = cocoon yield × weighted cocoon price
  • Raw silk equivalent = cocoon yield × reeling yield
  • Silk sales revenue = raw silk equivalent × silk price
  • Total cost = seed cost + leaf cost + labor cost + reeling processing cost + other cost
  • Profit = revenue - total cost
  • Margin = profit ÷ revenue
  • Break-even cocoon price = total cost ÷ cocoon yield
  • Mortality-adjusted ideal revenue = revenue ÷ survival rate

FAQ

What is the difference between Quick and Detailed?

Quick mode estimates with a single base price. Detailed mode uses grade ratios and grade unit prices to show cocoon sales differences.

How should I choose between cocoon sales and silk conversion?

Compare selling cocoons as they are versus sending them to reeling. It is useful when you want to decide the better route quickly on site.

Does mortality directly reduce revenue?

Not directly. The tool compares the ideal value derived from survival rate with the actual result, so you can see the room for improvement.

What units are supported?

Weight supports kg / g / lb / t, time supports hour / min / day, and pricing supports per kg / per lb / per t.

Is anything sent outside the browser?

No. By default, everything stays inside this browser for save and restore.

Can it be used internationally?

Yes. It supports multiple languages, kg/lb/t, hour/min/day, and ISO 4217 currency codes.

Notes

  • This tool is for estimating the direction of profitability. It may not match accounting profit.
  • Leaf cost, seed cost, labor rate, and reeling cost vary widely by site, so always adjust them to your own conditions.
  • Mortality rate is not a disease diagnosis. Use it to compare numbers and find room for improvement.
  • When comparing cocoon sales with silk conversion, do not forget to include reeling processing cost.
