Current sellable inventory ÷ Average daily units sold
Projected stockout date

Recommended inventory requirement

Available inventory
Current sellable inventory + Inbound inventory
Inventory gap
Recommended inventory requirement − Available inventory
Potential revenue at risk
max(0, Inventory gap) × Average selling price

This is not a demand forecast. Calculations assume your average daily unit velocity remains approximately constant, and this tool does not assign an arbitrary “inventory health score.” It's an estimate from the numbers you enter, not a review of your actual Seller Central account or a guaranteed outcome.
