What your results will look like

Sample

5 SKUs, 5 verdicts. Same columns as the input below + the dead-value and verdict the tool adds. Currency follows your ₹/$ toggle.

SKU Stock Units (30d) COGS Dead value Verdict
stockout-risk < 7 days cover · healthy < 20% dead · watch 20–50% · critical 50–90% · liquidate > 90% or velocity ~0

The math (open)

velocity = units30d / 30
safeStock = velocity × 30 (30-day cover window)
deadUnits = max(0, stock − safeStock)
deadValue = deadUnits × COGS
daysToClear = stock / velocity

Verdict: critical if >50% of stock is dead, watch if 20–50%, healthy otherwise.

Common questions

What counts as deadstock on Amazon FBA?

Inventory beyond a healthy cover window relative to your sales velocity. This calculator uses a 30-day cover. If you sell 10/day and have 600 units, 300 of them are deadstock by this definition.

Why does Amazon Seller Central not show me this?

Seller Central shows stock and sales separately, but never computes velocity-vs-stock per SKU. You have to do the math. This tool does it.

Do I need to upload my CSV?

No. Paste 5–10 SKUs manually. For full-catalog analysis with 13 loss patterns + recommended actions, use the full SLM app.

Where do my numbers go?

Numbers are sent to our calculation API to compute the result and are not stored. Your SKU names never leave the request — we recommend anonymizing them.
