Profit Calculator for Amazon Sellers

About this tool

Selling on Amazon looks profitable until you factor in fulfillment fees, referral commissions, shipping costs, and returns. A profit calculator for Amazon removes the guesswork by automating fee deductions and showing you the exact margin on each sale. Most sellers rely on rough mental math or spreadsheets that miss hidden costs, leaving money on the table.

If you're an Amazon FBA seller evaluating product profitability, comparing SKUs, or planning inventory investments, this calculator solves the core problem: knowing whether a sale is truly worth your time. Whether you're sourcing new products or auditing existing listings, you need a single trusted number showing net profit per unit after all Amazon commissions and operational costs.

Manual fee calculations are error-prone and time-consuming; this AI-powered calculator instantly applies Amazon's current fee structure, accounts for regional variations, and flags margin risks in seconds. Free alternatives force you to hunt down fee schedules and build your own models. The paid version delivers a complete profit breakdown with scenario analysis so you can optimize pricing and sourcing decisions.

Example: A seller enters a $15 cost, $49.99 listing price, and 2-pound FBA shipment. The tool reveals $18.46 net profit per unit after the 15% referral fee, $2.40 FBA weight surcharge, $1.54 fulfillment charge, and return assumptions—then shows what happens if you raise the price to $54.99 or drop the cost to $12. That clarity transforms product selection from guesswork to data.
