How to Calculate Weeks of Cover for Fashion & Apparel SKUs
Devottam Kumar 2026-08-12 5 min read
Weeks of Cover is the single most useful metric for e-commerce buyers. It converts abstract unit quantities into an exact operational deadline.
The Formula for Weeks of Cover
Weeks of Cover = Current Inventory On Hand ÷ Average Weekly Sales Velocity. If you have 200 units of a medium sweater and sell 25 units per week, you have exactly 8 weeks of cover.
Comparing Weeks of Cover to Supplier Lead Time
If your Weeks of Cover drops below your supplier's total lead time (e.g., 6 weeks of cover with an 8-week factory lead time), you are already facing a stockout unless an expedited order is placed.
