Two quick calculators for Amazon India FBA sellers: what Amazon owes you for stock it loses or damages, and the revenue you bleed per day a SKU is out of stock. Runs entirely in your browser.
The amount depends on when the unit was lost. Enter your numbers once, see both cases.
Running out isn't just lost sales today — it drags your rank and velocity after you restock. Here's the direct hit for one SKU.
Since 31 March 2025, Amazon reimburses inventory lost or damaged in its custody (before any sale) at your manufacturing / sourcing cost, not the sale price:
units × sourcing cost per unit
"Sourcing cost" is what you paid the manufacturer, wholesaler, or reseller — or your cost to produce it. It excludes shipping, customs, and prep.
As of September 2026 there's no way to declare this per SKU on Amazon India — Seller Central's cost-management page opens but doesn't work here (North America / Europe only). Amazon estimates instead, consistently low.
If a unit is lost or damaged after a customer ordered it, Amazon still reimburses the more generous way — the order's sale price minus the fees it would have charged:
units × (sale price − referral fee − FBA fee)
If fees meet or exceed your sale price, this floors at ₹0 — and the SKU is losing money on every ordinary sale, which is worth knowing on its own.
Your realised net is a touch lower — Amazon withholds 0.1% TDS per sale, reclaimed at tax filing. Unilytic's Returns Reconciliation view nets that out to match your Seller Central payouts.
Multiply your normal daily run-rate by how long the SKU was unavailable:
units/day × sale price × days out units/day × profit/unit × days out
The direct, conservative number — it ignores the rank and velocity drag after a stockout, which usually makes the true cost larger.
Want this computed for every SKU from your Inventory Ledger instead of one at a time? That's exactly what Unilytic does. You can also read our Amazon FBA seller guide on reimbursements and claims.
Unilytic reads your Amazon Inventory Ledger and surfaces claim-eligible events, under-reimbursements, and stockout risk across every SKU and warehouse — automatically, every day.
