Why Amazon FBA Fees Are More Complex Than They Appear
Selling on Amazon through FBA (Fulfillment by Amazon) gives you access to Prime shipping, Amazon's logistics network, and one of the world's largest buyer bases. The trade-off is a fee structure that operates on multiple layers simultaneously — and Amazon has added new fees and adjusted existing ones consistently over the past several years.
In 2026, a seller sending a small standard-size product to Amazon can face up to six distinct fee charges before netting a single dollar: a referral fee on the sale, a per-unit fulfillment fee, a monthly storage charge, a potential inbound placement service fee, an aged inventory surcharge if stock sits too long, and a closing fee in certain media categories. None of these are optional once you're in the FBA program.
The sellers who thrive in this environment are the ones who calculate every fee before selecting a product to sell — not after they've already sent inventory to a warehouse. Use our free Amazon FBA profit calculator to run your numbers in real time, and use this guide to understand exactly what each fee line means.
The Six Amazon FBA Fee Types Explained
Here is a complete overview of every fee category Amazon FBA sellers encounter in 2026. The sections below go deeper on each one.
| Fee Type | How It's Charged | Typical Range | Avoidable? |
|---|---|---|---|
| Referral Fee | % of total sale price per unit sold | 6%–17% | No — applies to all sales |
| FBA Fulfillment Fee | Flat per-unit fee based on size & weight | $3.06–$26.33+ | No — applies to all FBA orders |
| Monthly Storage Fee | Per cubic foot of inventory stored | $0.78–$2.40/cu ft | Partially — manage stock levels |
| Inbound Placement Fee | Per unit on new inventory shipments | $0.27–$1.58/unit | Yes — split shipments across FCs |
| Aged Inventory Surcharge | Per unit stored 271–365+ days | $0.50–$6.90/unit/mo | Yes — manage sell-through rate |
| Closing Fee | Flat per-item fee in media categories | $1.80/unit | Only applies to books, DVDs, etc. |
| Typical total for a $25 small standard-size product: $6.50–$9.00 (26–36% of sale price) | |||
Amazon Referral Fees 2026 — by Category
The referral fee is Amazon's primary revenue from third-party sellers — it's a percentage of the total sale price (including any shipping charged to the buyer) taken on every transaction. Rates vary significantly by product category, ranging from 6% on personal computers up to 17% in categories like Amazon Device Accessories.
For a complete rate table by category, see our dedicated guide on Amazon referral fees by category for 2026. The most common categories for FBA sellers and their 2026 rates are:
| Category | Referral Fee Rate | Minimum Referral Fee |
|---|---|---|
| Apparel & Accessories | 17% (items ≤$15: 5%) | $0.30 |
| Baby Products | 8% (items ≤$10: 8%) | $0.30 |
| Beauty & Personal Care | 8% (items ≤$10: 8%) | $0.30 |

FBA Fulfillment Fees 2026 — Size Tiers Explained
The FBA fulfillment fee covers Amazon picking, packing, shipping, and handling customer service for your orders. It's a flat per-unit charge based on the product's size tier — determined by the unit's dimensions and weight when packaged for shipment.
Amazon uses several size tiers. Getting your product into a smaller tier can make a significant difference to your cost per unit. Here are the 2026 rates for the most common tiers:
For large standard items with weight over 3 lb, Amazon adds a per-pound fee above the base rate — this can add $0.16–$0.24 per additional pound depending on tier. Use Amazon's FBA revenue calculator or our free profit calculator to get the precise fulfillment fee for your product's exact weight and dimensions.
Amazon FBA Storage Fees 2026 — Monthly & Long-Term
Every cubic foot of inventory sitting in Amazon's fulfillment centers costs money — every month. Storage fees are often underestimated by new FBA sellers, particularly those who overstock or whose products sell more slowly than projected.
Monthly Storage Fees
Monthly storage fees are charged between the 7th and 15th of each month for the prior month's average inventory volume. Rates differ between standard and oversize products, and between peak season (October–December) and off-peak (January–September):
| Storage Period | Standard-Size (per cu ft) | Oversize (per cu ft) |
|---|---|---|
| January – September (off-peak) | $0.78 | $0.56 |
| October – December (peak Q4) | $2.40 | $1.40 |
For a typical small standard-size product occupying roughly 0.05 cubic feet, monthly storage costs around $0.04 during off-peak and $0.12 during Q4. Those numbers sound trivial — but for a slow-moving product with 6 months of stock on hand, they compound quickly. For a full deep-dive, read our guide on Amazon FBA storage fees 2026.
Aged Inventory Surcharge (Long-Term Storage)
Amazon replaced its old long-term storage fee structure with an aged inventory surcharge that kicks in at different thresholds based on how long inventory has been at an FC:
| Days in Fulfillment Center | Surcharge per Unit/Month |
|---|---|
| 0 – 180 days | None (standard monthly storage only) |
| 181 – 270 days | None (but review recommended) |
| 271 – 365 days | $0.50 per unit per month |
| 365+ days | $6.90 per unit per month (or 15% of sale price if higher) |
The 365-day rate of $6.90/unit/month is particularly brutal — it can exceed your entire margin on low-priced products. The solution is proactive inventory management: set reorder points based on sell-through rate, run Amazon's Inventory Health reports monthly, and use removal orders or liquidation programs before stock ages past 270 days.
Inbound Placement Service Fee 2026
One of the most talked-about Amazon FBA fee changes in recent years is the inbound placement service fee, introduced in 2024 and still fully in effect in 2026. Understanding it is now essential for every FBA seller.
When you send inventory to Amazon FBA, Amazon wants your stock distributed across multiple fulfillment centers to minimise delivery times across the country. Previously, Amazon handled this redistribution at no visible cost to you. In 2024, Amazon began charging sellers who send inventory to a single receive location — because Amazon then has to do the redistribution work internally.
How Inbound Placement Fees Work
When you create a shipping plan in Seller Central, Amazon gives you options:
- Minimal shipment splits (1 location): You send everything to one fulfillment center. Amazon charges you an inbound placement fee per unit for the redistribution work.
- Partial shipment splits (2–3 locations): Reduced or no placement fee, but you manage sending to multiple addresses.
- Amazon-optimized splits: Send to Amazon's specified number of FCs. Typically zero placement fee, or a small discount per unit.
| Size Tier | Minimal Split (1 location) | Partial Split | Amazon-Optimized |
|---|---|---|---|
| Small standard | $0.27 per unit | $0.14 per unit | $0.00 – $0.06 |
| Large standard | $0.54 per unit | $0.27 per unit | $0.00 – $0.12 |
| Small oversize | $1.08 per unit | $0.54 per unit | $0.00 – $0.26 |
| Large oversize | $1.58 per unit | $0.79 per unit | $0.00 – $0.40 |
For sellers sending 500 units of a large standard product, choosing minimal split over Amazon-optimized shipment costs an extra $270 in placement fees alone. Across multiple replenishment shipments per year, this becomes a meaningful line item.
The practical advice: always check Amazon-optimized split first. The inconvenience of shipping to two or three locations is almost always worth the savings, especially on high-volume SKUs.
Worked Example: Complete FBA Fee Breakdown on a $25 Product
Let's put every fee together with a realistic product: a branded silicone kitchen spatula set in the Home & Kitchen category, selling at $24.99 on Amazon US. The product weighs 12 oz packaged and measures 12" × 5" × 2" — placing it in the small standard-size tier.
This is a healthy margin. But notice how quickly it changes if the product moves into the large standard tier (fulfillment fee rises to ~$3.86–$4.50), or if the referral category were apparel at 17% instead of 15%. Small parameter changes dramatically affect FBA profitability — which is why running the numbers precisely before sourcing a product is non-negotiable.

Amazon FBA Fees for UK Sellers in 2026
UK sellers using Amazon.co.uk FBA face a broadly similar fee structure, but with rates in GBP and some differences in tier thresholds and processing. Here are the key 2026 rates for UK FBA:
| Fee Type | UK Rate 2026 | Notes |
|---|---|---|
| Referral fee — most categories | 7%–15.3% | Varies by category, same structure as US |
| Fulfillment — small standard (≤400g) | £2.50 – £2.80 per unit | Based on weight bands |
| Fulfillment — large standard (≤1kg) | £3.10 – £3.80 per unit | Increases per 500g above 1kg |
| Monthly storage — off-peak (Jan–Sep) | £0.51 per cu ft | Charged on average daily units |
| Monthly storage — peak (Oct–Dec) | £1.21 per cu ft | Significantly higher Q4 rate |
| Aged inventory surcharge (365+ days) | £4.60 per unit/month | Or 15% of sale price if higher |
UK sellers also pay VAT-related considerations on fees, and cross-border selling between UK and EU marketplaces post-Brexit carries additional import/customs implications. If you sell on Amazon.co.uk and European marketplaces simultaneously through Pan-European FBA, fee structures and VAT registration obligations differ significantly — specialist accountancy advice is recommended for multi-marketplace EU/UK operations.
How to Reduce Your Amazon FBA Fees in 2026
You can't eliminate FBA fees, but strategic decisions at the product sourcing, packaging, and inventory management stage can meaningfully reduce your total cost per unit. Here are the most impactful levers:
-
Optimize packaging dimensions to hit the smallest size tier
The difference between small and large standard fulfillment fee is $0.80–$1.20 per unit. If your product can be packaged in a smaller box without damage risk, the investment in new packaging pays back quickly at volume. Measure everything — Amazon measures it too, and will charge the higher tier if your declared dimensions are wrong.
-
Use Amazon-optimized inbound splits to eliminate placement fees
Choosing Amazon's recommended multi-FC split when creating shipment plans typically eliminates or dramatically reduces the inbound placement fee. On 1,000 units of a large standard product, this alone saves $540 versus minimal split. The inconvenience of sending to 2–3 addresses is worth it at any significant volume.
-
Maintain lean inventory levels — especially heading into Q4
Over-sending inventory before peak season is one of the most common and costly FBA mistakes. You'll pay 3× higher storage rates in October–December, and any unsold stock risks the aged inventory surcharge. Send 90–120 days of expected sales into FBA, not a year's worth.
-
Use removal orders or liquidation before stock ages past 270 days
Amazon charges $0.50 per unit/month from day 271 — minor until it compounds. At day 365, the rate jumps to $6.90/month. Removal orders cost $0.97–$2.50 per unit (much cheaper than aged storage). Run monthly Inventory Age reports and set a 240-day removal threshold as your floor.
-
Enroll in the New Seller Incentives or FBA New Selection program
Amazon periodically offers free storage months, rebates on fulfillment fees, and sponsored ads credits for new products and new sellers. New Seller Incentives (for accounts under 12 months) can offset thousands in early fees. Check Seller Central's Growth tab for current promotions applicable to your account.
-
Evaluate FBM for heavy, low-velocity, or oversized products
FBA fulfillment fees for oversize items can reach $14–$26 per unit. If your product is large, heavy, or sells fewer than 10–15 units per month, FBM may be more cost-effective — you lose Prime badge visibility but can keep significantly more margin. See our FBA vs FBM comparison for a worked example.
Amazon FBA vs Etsy vs eBay — Total Fee Comparison
If you're deciding where to sell, total platform fees are a key part of the equation. Here's how Amazon FBA stacks up against Etsy and eBay for a typical $25 product sale in 2026:
| Platform | Core Fee % | Fulfillment | Total Fees on $25 Sale | Take-Home |
|---|---|---|---|---|
| Amazon FBA | 15% referral | ~$3.22 (FBA fee) | ~$7.00 (28%) | ~$18 |
| Etsy | 6.5% + processing | You ship yourself | ~$2.80 (11%) | ~$22.20 |
| eBay | 13.25% FVF | You ship yourself | ~$3.60 (14.4%) | ~$21.40 |
| Shopify | 2.9% + $0.30 | You ship yourself | ~$1.03 (4.1%) | ~$23.97 |
Amazon FBA's higher total fee is justified by Prime access, customer trust, and Amazon's traffic — but the fee burden means your product margin must be strong enough to absorb it. Amazon works best for products with a minimum 40–50% gross margin before fees. For handmade or unique items with lower COGS ratios, Etsy often returns more per sale despite smaller audience reach.

How to Calculate Your Real Amazon FBA Profit Margin
With all fees understood, here is the complete FBA profit calculation formula every seller should apply before committing to a product:
Total FBA Fees = Referral Fee + Fulfillment Fee + Storage (per unit) + Inbound Placement Fee
Net Revenue = Gross Revenue − Total FBA Fees
Profit = Net Revenue − COGS − Packaging − PPC Cost per Sale − Overhead
Profit Margin % = (Profit ÷ Selling Price) × 100
