Weeks of supply: Definition, Formula & Why It Matters
Also called: Weeks of cover
Weeks of supply estimates how many weeks your current inventory will last at your recent sales pace: current units divided by average weekly units sold. It is the weekly companion to days-to-sell and is useful for planning reorders.
Weeks of supply formula
Example
60 units on hand selling 8 per week is 7.5 weeks of supply.
Why it matters for Reverb sellers
Weeks of supply tells you whether you have enough stock to cover demand until your next purchase arrives. Ideally it slightly exceeds your supplier lead time so you do not run out while waiting.
