Excess inventory checker Cover days vs your target — not Amazon’s official IPI.
The formula Cover = on-hand ÷ daily sales. Excess ≈ max(0, on-hand − sales × target days).
Not Amazon IPI. See IPI guide , IPI .
Worked example 2,400 on hand ÷ 20/day = 120 days; vs 90 target → excess ≈ 600 .
Common questions Is this IPI? No. Amazon IPI is a proprietary 0–1000 score.
Target cover? Often 45–90 days by category.
Zero sales? Use a proxy or treat as dead/slow — zero blocked.
If excess? Pause reorders, promote, or remove aged FBA stock.
