Amazon FBA fees are the charges Amazon takes for storing, picking, packing and shipping your products and handling returns. On top of them sit the referral fee on every sale and your selling plan fee. Together they are usually the biggest cost after the product itself, and most sellers underestimate them. This guide walks through every fee, what triggers it, and how to lower it.
Amazon FBA fees are a per-unit fulfillment fee (set by size tier, shipping weight and price band) and a monthly storage fee, plus situational fees: inbound placement, low-inventory-level, aged-inventory surcharge, returns processing and removal or disposal. The referral fee, commonly around 15% in many categories, and the $39.99 Professional plan apply on top. Confirm current rates in Seller Central.
Stop guessing. Enter your price, cost and dimensions and see your size tier, FBA fee, referral fee, margin and break-even ACoS per unit in seconds.
- The two fees you pay on every unit are the referral fee and the FBA fulfillment fee. Everything else is situational and mostly avoidable.
- Your size tier sets your fulfillment fee. A slightly smaller or lighter package can drop you into a cheaper tier.
- Since 2024, Amazon has priced fulfillment by price band too: lower fees on low-priced items, higher on higher-priced ones.
- Newer fees like the inbound placement fee and low-inventory-level fee punish poor inventory planning, not just big products.
- All numbers below reflect Amazon's latest published US fee schedule as we understand it. Confirm in Seller Central, because Amazon updates fees regularly.
What fees does Amazon charge FBA sellers?
Here is every fee most private-label sellers will meet, what it is, and when it applies. Rates change, often once or twice a year, so treat this as a map and check the exact numbers in Seller Central.
| Fee | What it is | When it applies |
|---|---|---|
| Referral fee | Amazon's commission on each sale, a percentage of the total sale price. Commonly around 15% in many categories, lower or tiered in some; many categories also have a per-item minimum. | Every sale, FBA or FBM |
| FBA fulfillment fee | Per-unit fee to pick, pack, ship and handle customer service. | Every FBA unit sold; set by size tier, shipping weight and price band |
| Monthly storage fee | Charged per cubic foot of inventory in Amazon's fulfillment centers. | Monthly; rates are higher in October–December |
| Aged-inventory surcharge | Extra charge on inventory that has sat in fulfillment centers too long. | Monthly, on units past Amazon's age thresholds (starting at roughly six months) |
| Inbound placement service fee | Per-unit fee based on how many locations you ship inventory to. | When you choose fewer inbound destinations than Amazon's optimized split |
| Low-inventory-level fee | Per-unit surcharge on standard-size items when stock stays low relative to demand. | When your supply stays below Amazon's threshold (check current rules and exemptions) |
| Returns processing fee | Per-unit fee on customer returns. | In some categories, or when an item's return rate exceeds Amazon's threshold |
| Removal / disposal fee | Per-unit fee to send inventory back to you or have it disposed of. | When you create a removal or disposal order |
| Prep and labeling | Charges or penalties when items arrive without required prep or labels. | When Amazon has to prep or label, or finds unplanned prep issues |
| Selling plan fee | Individual: a per-item fee on each sale. Professional: $39.99 per month. | Every month or every sale, depending on your plan |
Two plan notes. The Professional plan ($39.99 a month, as of Amazon's latest published US fee schedule) is what virtually every private-label brand needs, because it unlocks Brand Registry tools, advertising and bulk listing. The Individual plan charges per item sold instead and only makes sense at very low volume.
How do FBA size tiers work?
Your fulfillment fee is set first by your product's size tier, which Amazon calculates from the packaged unit's dimensions and weight. The main tiers are:
- Small standard. Small, light items, such as a flat package up to about 15 × 12 × 0.75 inches and under a pound. The cheapest tier.
- Large standard. Most private-label products: up to about 18 × 14 × 8 inches and 20 lb. Fees step up with shipping weight.
- Bulky. Items too big or heavy for standard size. Fees are much higher and rise with weight.
- Extra-large. Very large or heavy items, split into weight bands.
Within a tier, the fee depends on shipping weight. For most tiers that is the greater of the unit weight and the dimensional weight. Amazon uses a dimensional weight divisor (currently 139): dimensional weight = length × width × height (in inches) ÷ 139, in pounds.
That is why air in your box costs money. A light product in an oversized box gets billed on its dimensions, not its weight. Check the exact cutoffs in Amazon's current size tier table, because a fraction of an inch can move you up a tier.
How do FBA fees change with product price?
Since 2024, Amazon has priced fulfillment fees by price band as well as by size and weight. In broad terms, products under $10 get lower fulfillment fees, products in the middle pay the standard rate, and higher-priced products (roughly above $50) pay somewhat more. Referral fees are percentage-based, so they rise with price automatically.
What that means for pricing decisions:
- Pricing just under a band edge can lower your fulfillment fee, but only change price for a real reason. Conversion and margin matter more than a small fee difference.
- Low-price products benefit from the lower band, but the referral fee minimum and storage still hit hard on thin margins.
- Bundles raise price and weight at once. Run the numbers for the bundle, not the single unit.
What does a real FBA fee calculation look like?
Every number below is hypothetical, chosen only to show the math. Your fees will differ by category, size, weight and price. Use the calculator for your real figures.
| Line | Hypothetical amount | How it's worked out |
|---|---|---|
| Sale price | $29.99 | Your list price |
| Referral fee | $4.50 | 15% × $29.99 (assumed category rate) |
| FBA fulfillment fee | $5.00 | Assumed large standard, about 1 lb shipping weight |
| Monthly storage (per unit) | $0.15 | Assumed share of cubic-foot storage cost |
| Inbound shipping + placement (per unit) | $0.75 | Assumed freight plus placement fee |
| Product cost (landed) | $7.00 | Manufacturing plus freight to the US |
| Profit before ads | $12.59 | $29.99 − $4.50 − $5.00 − $0.15 − $0.75 − $7.00 |
| Margin before ads | ≈ 42% | $12.59 ÷ $29.99 |
In this example, Amazon's fees take about a third of the sale price before advertising. That 42% margin is also your break-even ACoS: if ad spend divided by ad revenue goes above it, each ad-driven sale loses money. Run your own numbers in the free FBA profit calculator.
Swap in your own price, landed cost and dimensions. The calculator estimates your size tier, fulfillment and referral fees, net profit, margin and break-even ACoS.
What are the newer FBA fees sellers miss?
The fees that surprise sellers most are the ones added or reworked since 2024. They are all about how you manage inventory, not what you sell.
- Inbound placement service fee. When you create a shipment in Send to Amazon, you choose a placement option. Splitting inventory across the multiple locations Amazon recommends usually lowers or removes the fee; shipping everything to one or a few locations costs more per unit. Compare the options and your own freight cost before confirming.
- Low-inventory-level fee. If your stock of a standard-size item stays low relative to demand, Amazon adds a per-unit charge. Amazon exempts some situations, such as new listings. Check Seller Central for the current thresholds.
- Aged-inventory surcharge. Monthly charges on units that have sat too long, rising the longer they sit. It is the cost of over-ordering.
- Returns processing fee. Applied to categories with high return rates or to items that exceed Amazon's return-rate threshold.
The low-inventory and aged-inventory fees pull in opposite directions: too little stock costs you, and too much costs you. That is why inventory planning is now a fee strategy. Our Amazon inventory management guide covers how to hit the middle.
How can you lower your Amazon FBA fees? 8 practical ways
- Right-size your packaging. Trim box dimensions and weight to drop a size tier or a weight step. This is often the single biggest saving.
- Check Amazon's measurements. If Amazon has your product in the wrong tier, you are overpaying on every unit. Compare the fee preview with your real dimensions and open a case if it's wrong.
- Plan inventory to avoid low-inventory fees. Reorder on lead time plus a safety buffer, so you don't sit below Amazon's threshold.
- Don't overstock into aged-inventory surcharges. Send in what will sell in the coming weeks and hold the rest in a 3PL or with your supplier.
- Compare inbound placement options. Weigh the placement fee against your freight cost for each option before confirming.
- Cut returns. Accurate listings, clear sizing and honest images reduce returns and any returns processing fees.
- Remove or liquidate dead stock early. A removal fee now is often cheaper than months of storage plus aged-inventory charges.
- Prep correctly before shipping. Arriving properly labeled and packed avoids prep charges and unplanned-service fees. Amazon has been changing which prep services it offers, so check current options for your items.
If FBA fees make a product unprofitable, fulfilling it yourself may be the answer. See our comparison of FBA vs FBM for private label. Selling on Walmart too? Our WFS vs FBA guide compares the two fulfillment programs.
