Shortage % In Fabric Costing: How To Apply It Correctly
A disciplined way to use shortage for warp and weft so you avoid both underquoting and unnecessary overpricing.
Shortage Is A Process Parameter, Not Guesswork
A common operational baseline is around 10%, but the right value depends on yarn behavior, process variation, and machine condition.
Treat shortage as a measurable production parameter and revise with actual issue/return records.
Apply Warp And Weft Separately
Warp and weft experience different process conditions; therefore, shortage must be applied independently.
If a fabric uses multiple wefts, each weft should have its own shortage setting.
- Warp_shortage_factor = 1 + warp_shortage/100
- Each_weft_shortage_factor = 1 + weft_shortage/100
- Total_cost = sum(stream_cost_with_its_own_shortage)
Operational Monitoring
Track actual vs estimated consumption by quality code and month. If your sheet is consistently conservative, reduce shortage responsibly.
If specific constructions repeatedly consume more, create quality-wise shortage profiles rather than one fixed number for all fabrics.
