Amazon Seller & FBA Fees Explained (2026)

By the Profitvana Editorial Team · Updated August 2026

Selling on Amazon involves three layers of fees: the referral fee on every sale, FBA fulfillment and storage fees if Amazon handles shipping, and your monthly plan. This guide breaks down each layer with 2026 numbers, shows how they stack on a real sale, and covers the hidden FBA costs that catch new sellers.

Layer 1: the referral fee

Amazon's referral fee is a percentage of each sale — typically 15%, ranging from 8% to 20% by category (a handful of niches run higher, like Amazon Device Accessories at 45%) — with a $0.30 minimum per item. It applies to the total the buyer pays, including shipping, for most categories.

Rates are frozen for 2025–2026 at 2024 levels, so you can price with confidence. The full category table is in our how much does Amazon take guide, and the Amazon fee calculator carries the complete schedule with price tiers.

Layer 2: FBA fulfillment fees

If you use Fulfillment by Amazon, each unit sold incurs a fulfillment fee based on its size tier and shipping weight. In 2026, typical standard-size items run about $3–$6 per unit; large or heavy items cost substantially more. Rates rose slightly in 2026 (about $0.08 per unit on average).

On top of fulfillment, monthly inventory storage is billed per cubic foot — and roughly triples during October–December peak season. That seasonality matters: holding slow inventory through Q4 can quietly erase a thin margin.

FBA cost	What drives it	Typical 2026 range
Fulfillment fee	Size tier + weight, per unit sold	$3–$6 standard-size
Monthly storage	Cubic feet stored	~$0.78/cu ft (Jan–Sep), ~$2.40 (Oct–Dec)
Aged inventory surcharge	Stock held 180+ days	Escalates with age
Inbound placement	How you split shipments to Amazon	$0–~$0.68/unit standard

Layer 3: the monthly plan

Professional sellers pay a $39.99 monthly subscription; Individual sellers pay $0.99 per item sold instead. The break-even is about 40 items a month — beyond that Professional is cheaper and unlocks advertising, bulk listing, and Buy Box eligibility.

How the layers stack on a real sale

Take a $60 kitchen product (15% category) sold via FBA: referral fee $9.00, fulfillment ~$4.50, storage and plan overhead ~$0.60 spread per unit — about $14.10 to Amazon, or 23.5% of the sale, before your product cost. The same product via FBM pays only the $9.00 referral fee, but you cover postage yourself.

Estimate your own numbers in the Amazon fee calculator: pick your category, then add your per-unit FBA or shipping cost into the item-cost field.

From experience: the costs FBA hides

Hands-on, FBA has two quiet drains beyond the headline fees. The first is long-term storage on inventory that does not sell fast enough — the aged-inventory surcharge escalates after 180 days, and stock that sits eats margin month after month. The second is the work of getting goods into Amazon's network: prep, labeling, inbound placement fees, and inbound shipping all cost time and money before a single sale.

The practical lesson: FBA rewards fast-moving, well-sized inventory. For slow or bulky items, the maths often favors fulfilling yourself (FBM). Model both before you commit a product to FBA — and re-check after any fee update, since fulfillment rates move more often than referral rates.

Frequently asked questions

What is the difference between referral fees and FBA fees?

The referral fee is Amazon's commission on every sale (usually 15%), paid by all sellers. FBA fees are separate per-unit charges for storage, picking, packing, and shipping — you only pay them if Amazon fulfils your orders.

Are Amazon fees the same for FBA and FBM sellers?

The referral fee and monthly plan are identical. FBA sellers add fulfillment and storage fees; FBM sellers pay their own postage instead.

How can I lower my Amazon fees?

Pick the right category (miscategorized items can overpay), keep inventory lean to avoid storage surcharges, right-size packaging to drop a size tier, and switch slow movers to FBM.
