How to Calculate Cotton Rates
In the textile and agricultural trading industry, calculating the Cotton Rate (specifically the cost of Lint or processed cotton) is crucial for ginners and spinners. The calculation converts the price of Raw Cotton (Phutti) into the effective cost of Lint after accounting for processing expenses and the recovery value of Cotton Seed (Banola).
The Cotton Rate Formula
The core logic involves determining the "Ginning Out Turn" (GOT), which is the percentage of useful lint obtained from raw cotton. The formula generally follows these steps:
- Total Cost: Price of Raw Cotton + Ginning Expenses.
- Seed Recovery: The revenue generated from selling the cotton seeds (by-product).
- Net Cost: Total Cost minus Seed Recovery.
- Final Rate: Net Cost divided by the Lint Yield weight, normalized to the standard weight unit (e.g., Maund or Quintal).
Key Variables Explained
Raw Cotton (Phutti) Price: The market rate at which the ginner purchases unprocessed cotton from farmers.
Ginning Expenses: This includes labor, electricity, factory overheads, and taxes associated with processing the raw cotton into lint.
Lint Yield (GOT %): The efficiency of the cotton. A higher percentage (e.g., 36% vs 33%) means more usable fiber and a lower final cost.
Wastage: A small percentage (typically 1-3%) of dust, moisture loss, and trash that is lost during the ginning process.
Example Calculation
If you purchase 40kg of Raw Cotton at 8,500 with expenses of 600, and the market price for seeds is 3,200:
Assuming a 35% Lint Yield and 2.5% Wastage, the seed yield would be 62.5%. The calculator above automates the complex math of deducting the seed value from your input costs to give you the precise manufacturing cost of the lint.
