Amazon FBA Fees 2026: Every Change and What It Costs You per Unit

Amazon used to change FBA fees once a year. You’d read the January rate card, update your spreadsheet and move on. In 2026 that habit stopped working. The changes arrived in stages from January through October, and several of them were never headline news.

This guide covers every change to Amazon FBA fees in 2026 in date order. For each one, you’ll see who it affects and what it costs per unit. Then we’ll stack them on a real product so you can see the combined effect on margin, and finish with what to fix before the 2027 rate card lands.

Amazon FBA Fees 2026: The Full Timeline

Here’s every change at a glance. The sections below break each one down.

AMZ Prep keeps a running list of these changes if you want to cross-check dates. Amazon’s own figures live in Seller Central and on its FBA pricing page.

January 1: Amazon Ended FBA Prep and Labeling Services

This change got the least coverage, and it may hit your operations harder than any rate increase. From January 1, 2026, Amazon stopped prepping and labeling inventory for US FBA sellers. Polybagging, bubble wrap, FNSKU labels and suffocation warnings are now your job, or a 3PL’s.

The real cost here is labor and process, not a fee line. If you prep in-house, you need space, materials and a reliable system. Mislabeled or poorly prepped units can also trigger the inbound defect fee below, so mistakes now cost twice.

If you’re setting up a prep station for the first time, clear storage locations make it much easier. The free warehouse bin location generator creates aisle-bay-level-bin IDs and barcode labels you can print right away. For the wider process, our guide to ecommerce warehouse operations covers layout and workflow.

January 15: Price-Based FBA Fulfillment Fees

This was the biggest structural change of the year. Amazon now sets FBA fulfillment fees using three inputs: size tier, shipping weight and price band. The bands are:

• Under $10: Low-Price FBA rates, now an average of $0.86 per unit cheaper than standard rates
• $10 to $50: the standard band, where most sellers sit
• Over $50: a higher band for premium products

GOAT Consulting’s breakdown shows the full rate tables. On average, fees rose about $0.08 per unit. That average hides a lot, though. Your actual change depends on where each SKU falls across all three inputs.

Watch the band edges. A product priced at $10.49 pays more to fulfill than the same product at $9.99. If you’re close to a threshold, a small price change can save more in fees than it costs in revenue. Run both prices through the Amazon fee calculator before you decide.

New Small Bulky Tier and the Overmax Surcharge

Amazon also added a Small Bulky size tier and an Overmax handling surcharge for extra-large items with very long dimensions. If you sell furniture, sporting goods or anything long and awkward, re-measure your packaging. A few inches can move a SKU into a much more expensive tier.

The Inbound Placement and Defect Fee Changes

Amazon restructured its inbound fees in 2026. Separate defect charges for late, misrouted or missing shipments were merged into one inbound defect fee, averaging about $0.60 per affected unit. Inbound placement fees also got new weight bands.

Inbound defect fees work like penalties. You only pay them when a shipment goes wrong. With prep now in your hands, though, the risk is higher than it used to be. Tight labeling, accurate box contents and on-time arrivals keep this line at zero.

Good SKU discipline helps a lot here. If your listings, labels and internal records don’t match, errors creep in at receiving. Our multi-channel SKU management guide explains how to keep one clean SKU map across every channel.

The Low-Inventory-Level Fee Now Works per FNSKU

The low-inventory-level fee charges you when stock runs too thin relative to demand. For 2026, Amazon started measuring it per FNSKU instead of at the parent level. It also extended the fee to bulky products and exempted grocery.

Per-FNSKU measurement means a single low variant, like one size or one color, can trigger the fee even when the parent listing looks healthy. Sellers with big variation families feel this most.

The fix is planning, not overstocking. Set proper reorder points and safety stock per variant, and use inventory forecasting to see low points before Amazon does.

Multi-Channel Fulfillment Fees Increased

If you use Amazon MCF to ship Shopify, eBay or website orders, those fees rose by about $0.30 per unit on average from January 15. AWD storage and transport also went up, with the West region hit hardest.

This is where multi-channel sellers need to look at the whole picture. An order that was cheap to ship through MCF last year may now cost more than fulfilling it from your own stock or a 3PL. When inventory and orders from every account sit in one place, you can choose the cheapest fulfillment route per order instead of defaulting to MCF.

Our guide to managing Shopify and Amazon inventory together covers how to split stock between FBA and your own warehouse without overselling either.

April 17: The 3.5% Fuel and Logistics Surcharge

In mid-April, Amazon added a 3.5% fuel and logistics surcharge to every FBA fulfillment fee in the US and Canada. It applies to MCF, Remote Fulfillment and Buy with Prime as well.

The key detail: the surcharge is 3.5% of the fulfillment fee, not of your sale price. As Fulfillbot explains, a $4.50 fulfillment fee adds about $0.16 in surcharge, not 3.5% of a $25 sale.

Amazon calls the surcharge temporary, and many sellers expect it to stay. Keep it on a separate line in your cost model so you can remove it cleanly if Amazon ever drops it.

FBA Storage Fees in 2026

Monthly storage is billed per cubic foot of average daily inventory, and the rate changes by season. For standard-size items, the January–September rate is under $1 per cubic foot. From October through December, it jumps to $2.40 per cubic foot, roughly triple. Oversize rates follow the same pattern at lower per-foot prices.

On top of that, aged-inventory surcharges apply once stock passes about 181 days, and a newer tier covers stock held over 15 months. Since March 1, removal and disposal fees are charged per unit as Amazon processes them, rather than up front.

The practical lesson: slow movers are expensive in 2026. Track inventory turnover by SKU, and clear stock that’s heading toward the aged thresholds before Q4 storage starts.

Holiday Peak Fees: October 15 to January 14

The holiday peak fulfillment fee adds about $0.32 per unit on average, ranging from roughly $0.19 for light items to over $2.70 for extra-large ones. It’s based on ship date, and the 3.5% surcharge is calculated on top. We covered the full margin math in our guide to Amazon peak fees 2026.

What Amazon FBA Fees 2026 Cost on a Real Product

Here’s the full fee stack on one product: a $24.99 large-standard item weighing 12–16 oz and taking up about 0.06 cubic feet.

That’s before product cost, inbound freight, prep and ads. Add $8.00 product cost, $0.60 inbound freight and $3.00 in ad spend per unit, and off-peak profit comes to $5.68, a 22.7% margin.

Now add the costs that moved to you in 2026. Say self-prep or a 3PL costs $0.30 per unit (get real quotes, since rates vary). Profit drops to $5.38. One inbound defect hitting a shipment, at about $0.60 per affected unit, cuts it further.

None of these changes is dramatic on its own. Together they move a comfortable margin into a range where a 15% discount or a rise in ad costs can wipe out most of the profit. Rerun every SKU with your real numbers in the Amazon FBA profit calculator. Then check what each SKU returns on the cash you’ve tied up in stock with the Amazon ROI calculator.

How to Protect Your Margins Under the 2026 Fee Structure

• Audit price bands. Check each SKU priced near $10 or $50. A small price change can move it into a cheaper fulfillment band.
• Re-measure packaging. Smaller boxes can drop size tiers and cut both fulfillment and storage fees.
• Price prep into COGS. Prep is now a real per-unit cost. Our guide to ecommerce COGS shows what belongs in landed cost.
• Compare fulfillment routes. With MCF fees higher, check whether your own stock or a 3PL ships non-Amazon orders more cheaply.
• Keep stock lean but steady. Avoid both aged-inventory surcharges and the low-inventory-level fee with per-variant reorder points.
• Reconcile payouts monthly. More fee lines mean more room for errors. Our marketplace payout reconciliation guide walks through it.
• Compare channel profit. Fees vary by marketplace, so a marketplace profitability analysis shows where each order actually earns money.

Looking Ahead: Amazon Fees 2027

The increases don’t stop in January. A new rate card takes effect on January 15, 2027, adding an average of about $0.19 per unit to fulfillment fees. Some tiers rise more: according to AMZ Prep, small-standard products priced $10–$50 go up about $0.40, and those over $50 about $0.70.

Peak fees end on January 14, but the 2027 rates start the very next day. Update your cost model now so January repricing starts from the right base.

The Bottom Line on 2026 Fees

Amazon FBA fees 2026 changed the way sellers have to manage costs. One annual update has become a series of changes: price bands, the fuel surcharge, self-prep, per-FNSKU stock rules and seasonal storage. Pricing on last year’s numbers means pricing at a loss on some SKUs.

Sellers who manage this well look at everything together: Amazon fees, other channels’ costs, and stock levels across every account. When inventory and orders from all channels sit in one place, you can see which SKUs to reprice, which orders to route away from MCF, and where stock is about to run low. Start with your top 20 SKUs this week, rerun them at current rates, and fix the worst margins first.
