Amazon FBA Profit Calculator

Amazon introduced over a dozen new fee types between 2024 and 2026. The Inbound Placement Fee alone adds $0.21–$1.58 per unit — a cost that didn't exist before April 2024. The Low-Inventory-Level Fee (LIVE) penalizes sellers who stock fewer than 28 days of supply. And starting January 2026, the Inbound Defect Fee charges $0.60 per unit if your shipment prep doesn't meet Amazon's new standards.

Most profit calculators online still use 2023 fee structures. That means your margin calculations could be off by 5–15%. Our calculator includes every current Amazon FBA fee so you can make sourcing and pricing decisions based on real numbers, not outdated estimates.
