Free: what is aged inventory actually costing you?

No upload, no signup — just one number. Amazon's aged-inventory surcharge quietly eats into margin on stock that's been sitting 6+ months, and most sellers have never seen the real total.

Units currently aged 6+ months

$0–$0

Estimated aged-inventory cost, per year

That's a rough, honest range — actual fees depend on size tier and exact age. Want the real number for every SKU you own, plus which ones to kill before they cost you more? See the full audit below ↓

Ballpark only, not from your account. Assumes roughly $10 to $18 per aged unit per year; small items usually cost less and bulky ones more. Check Seller Central for your exact fees. Runs entirely in your browser.

Find out which SKUs are quietly losing you money

Upload your inventory, get a Keep/Reprice/Kill call on every SKU, and turn a denied Amazon claim into a real rebuttal — in minutes, right in your browser.
