Amazon does not say whether the list, sale or promotional price sets the fulfillment price band. This calculator uses the price you enter, before any deal discount. Amazon does not publish how the 3.5% fuel and logistics surcharge is rounded, or whether it also applies to Overmax and bulky packaging fees. It is rounded to the cent here and applied to the fulfillment fee only. Amazon, not the seller, assigns the fee category. Check the Fee Preview report in Seller Central for the category Amazon uses. Amazon does not publish its per-unit rounding rule for referral fees; amounts are rounded to the cent here.

How to calculate Amazon FBA profit
Your real FBA profit margin is your selling price minus every cost Amazon touches before money reaches your account: the Amazon referral fee (15% in most categories; from 5% on Clothing at $15 or less up to 45% on Amazon Device Accessories, depending on category and price), the FBA fulfillment fee (picking, packing, shipping — set by your product's size tier, shipping weight and price band), monthly storage fees, your inbound shipping to Amazon warehouses, your advertising spend, a reserve for customer returns, and your cost of goods (including any import tariffs).
The formula: Net = Revenue − Referral − FBA fee − Storage − Shipping − PPC − Returns − COGS
Your real margin is Net ÷ Revenue × 100. Your break-even price is the lowest selling price from which Net stays at or above 0 — useful for knowing how low you can go during deals or price wars. Because Amazon's fees step at price edges (Low-Price FBA below $10, some referral tiers), the calculator solves it against the real fee schedule rather than a single rate.
Why most FBA calculators are wrong
Most FBA profit calculators — including Amazon's own — show you two numbers: the referral fee and the FBA fulfillment fee. That's it. The result looks like a healthy margin. The gap between that number and your real margin is where most FBA businesses quietly lose money.
What they miss:
- PPC (advertising) — the single biggest omission. Most sellers spend 10–20% of revenue on Amazon ads. Skip this and your margin looks 10–20 points higher than reality.
- Returns — clothing returns 15–30% of units. Each return costs you the return processing fee plus the probability the item can't be resold.
- Import tariffs — for sellers sourcing from China, tariffs add 30–145% to COGS. This alone can flip a profitable product to a losing one.
- Inbound shipping — freight to Amazon warehouses costs $0.50–$3.00+ per unit depending on your supplier location and shipment size.
The headline margin (price minus COGS) is the number that gets you excited about a product. The real margin is the number that determines whether you stay in business.
How Amazon FBA fees work in 2026
Amazon charges two primary fees for FBA sellers: a referral fee (a percentage of the sale price, by category) and an FBA fulfillment fee (a per-unit charge by size and weight tier, and by price band: under $10 gets Low-Price FBA rates, $10–$50 is the standard rate, and standard-size items over $50 pay more). On top of those sit storage, an inbound placement fee, a low-inventory fee, and — new in 2026 — a 3.5% fuel & logistics surcharge on fulfillment fees, effective April 17, 2026. The 2026 schedule took effect January 15, 2026, raised fulfillment fees by about $0.08 per unit on average, and split the old Large Bulky tier into Small Bulky and Large Bulky. A separate, higher peak card applies to units shipped October 15, 2026 through January 14, 2027.
Referral fees are 15% for most categories, 8% for consumer electronics, and reach 45% for Amazon device accessories, with a $0.30 minimum per unit in most categories (Grocery and Gourmet, Media, Video Games, Video Game Consoles and Gift Cards have none; Fine Art has none on Seller Central but $1.00 on sell.amazon.com, and this calculator applies the $1.00). Some categories charge one rate on the whole price by price tier (Beauty, Health and Personal Care is 8% at $10 or less, then 15%); others charge each portion of the price at its own rate (Electronics Accessories is 15% on the first $100 and 8% above; Watches drop to 3% only on the portion above $1,500). Amazon, not the seller, assigns the fee category — check your Fee Preview report.

Fulfillment tables are Amazon's non-apparel, non-dangerous-goods cards (apparel and hazmat have their own), before the 3.5% fuel & logistics surcharge. Amazon’s pages disagree on whether the 2-inch minimum width and height applies to large standard items. Its own worked examples only add up if it does, so it is applied here. Amazon does not say whether the list, sale or promotional price sets the fulfillment price band. This calculator uses the price you enter, before any deal discount. Amazon does not publish how the 3.5% fuel and logistics surcharge is rounded, or whether it also applies to Overmax and bulky packaging fees. It is rounded to the cent here and applied to the fulfillment fee only. Amazon does not publish its per-unit rounding rule for referral fees; amounts are rounded to the cent here.
