Amazon Commission Calculator for Seller

About this tool

Selling on Amazon means navigating a complex fee structure—FBA fulfillment fees, referral rates, storage costs, and category-specific surcharges all eat into your margin. Most sellers manually calculate these in spreadsheets or use incomplete tools that hide crucial category details. This calculator solves the problem by computing your exact take-home profit in seconds.

If you're an Amazon seller managing inventory across multiple categories, pricing products competitively, or auditing your FBA vs. FBM economics, you need precise fee data. Whether you're launching a new SKU, evaluating a repricing strategy, or reconciling your seller dashboard, accurate commission math determines whether a product is worth your time and capital.

Free tools often lump all categories together or rely on outdated fee schedules. This AI-powered calculator applies current Amazon fee tables, accounts for regional variations, and surfaces hidden fees most calculators skip. The paid report breaks down every cost line by line so you see exactly where your margin goes.

Example: A seller enters a $50 item in Electronics with FBA. The tool instantly shows the $7.50 referral fee, $3.85 fulfillment charge, and any applicable long-term storage cost—revealing a net of $38.65 before your own COGS. The paid version compares FBA vs. FBM side-by-side and exports a full profit forecast.
