How to Use the Amazon FBA Calculator
Enter your selling price, what the product costs you per unit, and your shipping cost to get it into Amazon’s warehouse. Pick your category, which sets the referral fee percentage, and your size tier, which sets the FBA fulfillment fee. The calculator instantly shows every fee, your net profit per unit, your margin, your return on investment, and the minimum price you need to charge to break even. Adjust any input to test pricing scenarios before you commit to inventory.
The Fees This Calculator Covers
The referral fee is Amazon’s commission on every sale, typically 15 percent for most categories, 8 percent for electronics, and up to 20 percent for jewelry, with a minimum of 30 cents. The FBA fulfillment fee is the per-unit charge for Amazon picking, packing, and shipping your product, based on its size tier and weight. Since April 2026, a 3.5 percent fuel and logistics surcharge applies on top of every fulfillment fee, which this calculator includes automatically. Monthly storage adds a per-unit cost based on the space your inventory occupies, roughly 78 cents per cubic foot from January to September and about three times that during the fourth quarter.
How ROI Is Calculated for Amazon FBA
ROI, or return on investment, tells you how hard your cash works. It is your net profit divided by what you invested in the unit — the product cost plus shipping — expressed as a percentage. If a unit costs you $8.70 all-in and you clear $6.50 profit after all Amazon fees, your ROI is about 75 percent. Many experienced sellers look for at least 30 to 50 percent ROI to leave room for ads, returns, and fee increases. Margin, by contrast, is profit divided by the selling price, and tells you how much of each customer dollar you keep.
FBA vs FBM: A Quick Note
This calculator models FBA, where Amazon stores and ships your products. With FBM (Fulfilled by Merchant), you skip the fulfillment fee and storage but pay your own packing and shipping instead, and you still pay the referral fee. To compare, set the size tier to manual entry, enter zero for the fulfillment fee and storage, and add your own shipping cost per unit to the product cost.
Frequently Asked Questions
How much does Amazon take per sale?
For a typical product, Amazon takes the referral fee (usually 15%) plus the FBA fulfillment fee ($3.35 to $7 for standard sizes) plus the 3.5% fuel surcharge and storage. On a $30 product that often totals $9 to $12.
What is a good ROI for Amazon FBA?
Many sellers target at least 30 to 50 percent ROI per unit. Below that, ads, returns, and fee changes can erase your profit quickly.
Are these the official Amazon fees?
The rates reflect the January 2026 US fee schedule with the April 2026 fuel surcharge, but exact fees depend on your product’s precise dimensions, weight, and price band. Always verify in Seller Central’s Revenue Calculator before ordering inventory.
Does this include the monthly seller plan?
No. The Professional plan ($39.99/month) or Individual plan ($0.99/item) is a separate account-level cost. Divide the monthly fee by your expected unit sales and add it to your ad cost field if you want it included.
