How Amazon FBA fees work
Amazon takes a few separate fees out of every FBA sale, and a product that looks profitable at the shelf price can lose money once they are added up. This is what each one is and what moves it.
Referral fee
A percentage of the selling price that Amazon charges on every sale. Most categories are around 15 percent, some are lower or tiered by price, and most have a minimum of $0.30. It rises and falls with your price.
FBA fulfillment fee
Covers picking, packing and shipping the order to your customer. It is set by the product's size tier and shipping weight, and a lower fee applies to cheaper items, so the same product can cost different amounts at different prices.
Inbound placement fee
Charged per unit when you send inventory to fewer Amazon warehouses than Amazon would choose. Letting Amazon split the shipment avoids it. Sending to one location is simpler but costs more, and the amount depends on size, weight and which region you ship to.
Storage and other fees
Monthly storage, long-term storage surcharges, returns processing and advertising come on top. This calculator leaves them out unless you add them as other costs, so build in a margin of safety.
How to tell if a product is worth buying
Start with profit after fees, not the gap between your cost and the selling price. A healthy wholesale product usually clears at least 15 percent margin and a return on investment above 30 percent, because returns, storage and ads will take a share.
Then check the price history. If today's Buy Box price sits well above its 90-day average, your profit may not last. If it sits well below, you may be looking at a temporary dip.
Finally, read the sales rank. A lower rank means more sales. A rank that is improving across 30, 60 and 90 days means demand is growing, which is the best sign for a reorder.
Questions
Amazon FBA calculator FAQ
Paste an ASIN or an Amazon product link into the box and press Calculate. The calculator looks the product up, shows its Buy Box price, its 30, 60 and 90 day average prices, its sales rank and the Amazon fees at that price. Then enter what the product costs you and it works out profit, margin, ROI and your break-even price.
The referral fee (Amazon's percentage of the selling price, which depends on the category), the FBA fulfillment fee (which depends on the product's size and weight and steps up with price), and an estimate of the inbound placement fee. It does not include monthly storage fees, aged inventory surcharges, returns processing, advertising or taxes. Put those in the other-costs box if you want them counted.
From Apex's own product database. Prices and ranks are snapshots of a market that moves every day, so treat them as a starting point and check the live listing and Seller Central before you place an order.
A per-unit fee Amazon charges when you send inventory to fewer locations than it would choose itself. Letting Amazon split the shipment across its network (Amazon-optimized splits) carries no placement fee. The calculator lets you compare sending to one, two or three locations in the East, Central or West region. Amazon updates these fees, so if Seller Central shows you a different figure, type it into the FBA fee override or the other-costs box.
Margin is profit divided by the selling price. ROI is profit divided by what you spend on each unit. If you spend $10 and sell for $20 with $5 of fees, your profit is $5, so margin is 25% and ROI is 50%. Sellers who buy wholesale tend to watch ROI because it measures the return on the money they tie up in inventory.
There is no single right number. Many wholesale sellers set a floor somewhere between 15% and 30% after all costs, then raise it for slow sellers, high prices or products with many competing sellers, and lower it for fast sellers they can reorder often. Use the calculator to see where a product actually lands before you decide.
Amazon does not publish sales volume, so it is inferred from Best Sellers Rank using a curve that depends on the category's size. It is shown as a range on purpose, because a single number would claim more precision than the method has.
Apex holds data on a large share of the Amazon catalog but not every listing, and brand-new or rarely sold products can be missing. Check the ASIN against the product page for typos. If it is correct, that listing is not in the database yet.
