It's a tool that watches every return and the fees Amazon adds to process it, then deducts the full cost from your live profit. It plugs refund volume into your P&L and shows return rate per SKU inside Winners & Losers.
Most sellers underestimate refund cost by 30-60%. Seller Central reports refunded revenue, not the refund admin fee, return processing fee, lost FBA inbound, or removal and disposal fees. Nova captures all of them through the same feed powering the profit tracker, FBA fee calculator, and fees calculator.
The Net Refund Cost formula
Net Refund Cost = Refunded revenue + Refund admin fee + Return processing fee + Lost FBA inbound shipping + Removal/disposal cost
Nova calculates this per refund, per SKU, per marketplace. The result lands in your product performance dashboard so you can decide whether to relist, repackage, or retire a SKU before another quarter of returns hits.
