Quick answer
How do I calculate sewing thread cost per garment?
Thread cost = thread consumption per garment (m) ÷ cone length (m) × cone price.
Item cost = Quantity per garment × Rate
How it works
Trims Cost Calculator
Cost every trim on the BOM, including sewing thread by cone, with a trims wastage allowance.
Each trim is priced per garment, thread is apportioned from the cone price, and a wastage allowance covers shortages and rejects.
Formula
The formula, in full
- Item cost
- Quantity per garment × Rate
- Thread cost
- Thread m ÷ Cone length × Cone price
- Trims / piece
- Σ item costs × (1 + Wastage%)
Example
Shirt BOM
- 01Buttons = 8 × 0.75 = ₹6.00
- 02Thread = 180 ÷ 5,000 × 95 = ₹3.42
- 03Net = ₹17.12 → with 3% = ₹17.63
Use “Load Example” above to run this example in the calculator.
