Calculate Amazon FBA profit, profit margin, ROI, and total Amazon fees with this free Amazon FBA Calculator.
The Amazon FBA Calculator helps sellers find their true net profit per unit after Amazon referral fees, FBA fulfillment fees, and product costs. Unlike Amazon's own revenue calculator, this FBA profit calculator shows you profit margin percentage, ROI on your invested capital, a visual health indicator, and a reverse calculator that answers 'what price do I need to hit my target profit margin?' — all in one place, with no login required. It doubles as an Amazon profit calculator and an Amazon ROI calculator, so you can evaluate FBA profitability from multiple angles before committing to inventory.
Enter your target margin to find the minimum sale price needed.

This free Amazon FBA profit calculator gives you a complete picture of your unit economics in under 30 seconds. Here's how to use every field accurately.
Use your current Amazon listing price, or the price you're planning to set. If you're testing different price points, change this field and the results update instantly. This is the amount the buyer pays — not including Amazon's promotional discounts.
This is your landed cost per unit — what you paid the supplier plus any inspection fees. Do not include inbound shipping to Amazon here; that goes in the next field. If you sourced from Alibaba, use the per-unit cost at your factory quote quantity.
This is the cost to ship each unit from your supplier (or your prep center) to Amazon's fulfillment center. For sea freight from China, divide your total freight cost by the number of units in the shipment. Typical range: $0.50–$2.50 per unit depending on weight and shipping method.
Find your FBA fee estimate in Amazon Seller Central under 'FBA Revenue Calculator', or check the FBA fee schedule. The fee depends on your product's size tier (determined by dimensions and weight). Example configured rates: Small Standard (<1 lb) = $3.22, Large Standard (<1 lb) = $3.58, Large Standard (1–2 lb) = $5.06.
The default is 15%, which applies to many categories. Adjust this for your specific category: Electronics = 8%, Clothing = 17%, Books = 15%, Grocery = 8%. You can verify your rate in Seller Central under 'Selling on Amazon fees'.
The colored progress bar tells you your margin health at a glance. Green = Healthy (≥15% margin). Orange/yellow = Thin margin (5–15%). Red = Loss or near-zero. The badge in the top right updates automatically: Loss / Thin margin / Healthy / Strong margin (≥25%).
Enter your target margin percentage in the Reverse Calculator below the results. The tool instantly tells you the minimum sale price you'd need to charge. This is the most useful feature for repricing decisions — start with your cost structure, not your competitor's price.
Amazon charges two main fees: a referral fee (typically 8–15% of the sale price depending on category) and an FBA fulfillment fee (based on the item's size and weight tier). For a standard product selling at $29.99 with a 15% referral fee and $5.10 FBA fee, Amazon takes approximately $9.60 before you account for your product cost and shipping.
