Two quick calculators for Amazon India FBA sellers. Estimate the reimbursement you're owed when Amazon loses or damages your stock, and the revenue you bleed for every day a SKU is out of stock. Everything runs in your browser — nothing is sent anywhere.
What Amazon owes you for lost or damaged inventory
Under Amazon's current FBA inventory reimbursement method, the amount depends on when the unit was lost. Enter your numbers once and see both cases.
What a stockout actually costs you
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.
The formulas, written out
Reimbursement — before a customer order
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. If you don't enter your cost of goods per SKU in Seller Central, Amazon uses its own (lower) estimate.
Reimbursement — after a customer order
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.
This is what Amazon's policy reimburses. Your realised net is a touch lower — Amazon also withholds 0.1% TDS (Tax Deducted at Source) on each sale, which you reclaim at tax filing. Unilytic's Returns Reconciliation view nets that out so its estimates match your Seller Central payouts.
Stockout cost
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
This is the direct, conservative number. It ignores the rank and velocity recovery drag that follows a stockout, which typically 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.
This is one SKU. Unilytic does it for your whole catalog.
Unilytic reads your Amazon Inventory Ledger and surfaces claim-eligible events, under-reimbursements, and stockout risk across every SKU and warehouse — automatically, every day.
