Amazon FBA fees explained: the 4 types every seller pays
Every unit you sell through FBA carries up to four separate Amazon FBA fees . Think of them as a stack — each one is calculated differently, and they add up fast if you price without doing the math first:
| Fee | What it covers | How it is charged |
|---|---|---|
| Referral fee | Amazon's commission for the sale | Percentage of the total sale price (varies by category) |
| FBA fulfillment fee | Picking, packing, shipping, customer service, returns | Flat fee per unit by size tier and weight |
| Monthly storage fee | Warehouse space your inventory occupies | Per cubic foot per month (higher Oct–Dec) |
| Inbound placement fee | Distributing your inventory across fulfillment centers | Per unit, varies by size tier and shipment option |
Key takeaway: There is no single "Amazon FBA fee" — it is a stack of four. Price your product only after you have estimated all four, not just the headline referral percentage.
Amazon referral fees: the percentage Amazon takes
The referral fee is Amazon's commission on every sale, calculated as a percentage of the total sale price (including shipping charges you set). Most categories sit around 15%, but it varies: some categories are lower, some higher, and many have a minimum per-item floor.
This is the fee sellers most often underestimate, because it applies to the full amount the buyer pays — not your net. On a $30 sale at a 15% referral rate, Amazon takes $4.50 before any other fee is counted. It applies whether you use FBA or FBM; it is the cost of selling on the marketplace itself.
Key takeaway: Budget roughly 15% of your sale price for the referral fee as a starting point, then confirm your exact category rate in Seller Central — the category, not the fulfillment method, sets this fee.
FBA fulfillment fees: pick, pack and ship
The FBA fulfillment fee is what you pay Amazon to handle the physical work: receiving your inventory, picking units when orders arrive, packing them, shipping to the customer, handling customer service, and processing returns. It is a flat per-unit fee set by size tier (small standard, large standard, bulky, etc.) and weight.
Two things catch sellers out here. First, size tiers have hard cutoffs — a product one centimeter over a threshold can jump an entire tier, so packaging dimensions deserve real attention. Second, dimensional weight can apply to large items, meaning you may pay on the greater of actual or dimensional weight. Designing packaging to sit safely inside a cheaper tier is one of the highest-ROI exercises in FBA.
Key takeaway: Fulfillment fees are driven by size tier and weight. Measure your packaged product carefully — shaving a tier boundary can save more per unit than most PPC optimizations.
What is the Amazon inbound placement fee?
The Amazon inbound placement fee is charged when you send inventory to Amazon's fulfillment network. Amazon distributes your stock across multiple fulfillment centers to keep it close to buyers; the placement fee covers that inbound distribution. It is charged per unit and varies by size tier and by which shipment option you choose.
Sellers typically have a choice: send inventory to a single location (higher placement fee, lower freight hassle) or split shipments across multiple fulfillment centers yourself (lower placement fee, more freight coordination). Which is cheaper depends on your freight costs and unit economics — there is no universally right answer.
If you want to model the tradeoff, our placement split calculator compares the options side by side for your shipment.
Key takeaway: The inbound placement fee is the cost of getting your inventory into Amazon's network. Compare single-location vs. split shipments on your real freight numbers before deciding.
Monthly storage fees (and why slow sellers fear them)
Monthly inventory storage fees are charged per cubic foot of warehouse space your products occupy, and they rise sharply in October through December. For fast-moving products the fee is trivial. For slow movers it compounds month after month — and aged inventory can attract additional long-term storage surcharges.
This is the fee that quietly kills profitability on dead stock: a product sitting unsold for six months has paid six rounds of storage while earning nothing. If a SKU is not moving, every month you wait is a decision to keep paying. (Our guide to the FBA removal order decision covers exactly when to cut dead stock loose.)
Key takeaway: Storage fees punish slow inventory. Track sell-through per SKU monthly, and treat anything gathering dust as a candidate for removal, liquidation or discount.
FBA fee example: what the stack looks like on a $30 product
Here is how the four fees stack on one illustrative unit. These numbers are an illustrative example only — Amazon updates fee schedules periodically, so always confirm current rates in Seller Central before making pricing decisions:
Notice the punchline: before product cost, inbound freight, or a single dollar of ad spend, 38% of the sale price is already spoken for in this illustration. That is why experienced sellers work backwards from fees to set prices, instead of pricing first and discovering the margin later.
Key takeaway: On a typical small standard-size product, expect Amazon's cut to land somewhere around a third of your sale price. Never guess — model it.
5 ways to lower your Amazon FBA fees
You cannot negotiate Amazon's fee schedule, but you can absolutely change which fees apply to you and how heavily:
1. Right-size your packaging. Size tiers have hard cutoffs. If your packaged product sits just over a tier boundary, redesigning the box can drop your per-unit fulfillment fee permanently.
2. Kill slow-moving SKUs. Storage fees compound monthly. Anything with poor sell-through should be removed, liquidated or discounted before storage eats the margin — see our FBA removal order guide for the decision math.
3. Compare placement options on real numbers. Single-location vs. split shipments is a math problem, not a preference. Run both through the placement split calculator with your freight quotes.
4. Price with fees baked in. Use an FBA fee calculator before setting your price, and re-check whenever Amazon announces fee changes — usually ahead of the new year and Q4.
5. Watch dimensional weight. For larger products, you may be charged on dimensional rather than actual weight. Compress packaging where possible; air is the most expensive thing you can ship.

Amazon FBA fees FAQ
There is no single Amazon FBA fee — it is a stack of four: a referral fee (a percentage of the sale price, commonly around 15% depending on category), a per-unit fulfillment fee set by size tier and weight, monthly storage fees per cubic foot, and an inbound placement fee per unit. On a typical small product the combined fees often land around a third of the sale price. Use our free FBA calculator to estimate your exact fees.
Amazon takes a referral fee on every sale — a percentage of the total sale price that varies by category (around 15% for many categories, with minimums per item). On top of that, FBA sellers pay fulfillment, storage and placement fees. Always check your category rate in Seller Central, as Amazon updates fee schedules periodically.
The inbound placement fee is what Amazon charges to receive your shipment and distribute your inventory across its fulfillment centers. It is charged per unit and varies by size tier and shipment option — sending to a single location usually costs more per unit than splitting shipments yourself. Compare both options with our placement split calculator .
Storage is a separate Amazon FBA fee, charged monthly per cubic foot of space your inventory occupies — and rates rise in October through December. Slow-moving inventory also risks long-term storage surcharges, which is why dead stock should be removed, liquidated or discounted quickly.
