How Much Does It Cost to Sell on Amazon in 2026? Complete Guide

Selling on Amazon in 2026 costs the average seller between 25-45% of gross sales revenue. Referral fees held flat at 8-15%, but FBA fulfillment fees rose on January 15, 2026 by an average of $0.08 per unit — and on April 17, 2026 Amazon added a 3.5% fuel and logistics surcharge on top of every US and Canada fulfillment fee. The costliest change this year isn't the fulfillment fee at all: the aged inventory surcharge now starts at 181 days instead of 271.

What Actually Changed in 2026?

Amazon confirmed no new FBA fee types for 2026 and froze referral fees for a second consecutive year. The increases landed elsewhere. Fulfillment fees rose on January 15, 2026, and the increase was not uniform: small standard-size items priced $10-$50 absorbed roughly $0.25 per unit, while items above $50 absorbed roughly $0.51. Then on April 17, 2026, a 3.5% fuel and logistics surcharge was layered on top of the fulfillment fee itself — meaning every calculation you ran in January is now understated. If you priced your catalog off a 2025 fee table, you are running on a thinner margin than your spreadsheet shows.

How Much Are Referral Fees in 2026?

Referral fees range from 8% to 15% across most categories, with the majority of products sitting at 15% and electronics at 8%. A handful of niche categories run higher. Apparel is tiered: 5% for items at or under $15, 10% for items between $15 and $20, and 17% for items above $20. This is the base cost Amazon takes on every sale regardless of fulfillment method, calculated on the total sale price including shipping but excluding tax. None of these rates increased in 2026.

What Do FBA Fulfillment and Storage Cost Now?

FBA fulfillment starts at $3.11 for a small standard-size item of 2 oz or less (as of July 2026) and scales with size and weight — plus the 3.5% fuel and logistics surcharge applied since April 17, 2026. Monthly storage runs $0.78 per cubic foot for standard-size inventory from January through September, jumping to $2.40 per cubic foot during peak season in October through December. Inbound placement fees run $0.14 to $1.50 per unit depending on weight and whether you split shipments across fulfillment centers yourself or pay Amazon to do it.

Which 2026 Costs Catch Sellers Off Guard?

The aged inventory surcharge is the year's most consequential change: it now begins at 181 days of storage, down from 271 days in 2025 — a full 90 days earlier. At 12-15 months the rate is $0.30 per unit or $6.90 per cubic foot; past 15 months it rises to $0.35 per unit or $7.90 per cubic foot. Working against it, the low-inventory-level fee applies when supply drops below 28 days, and as of 2026 it is calculated at the FNSKU level rather than the parent ASIN. A single variation can trigger the fee while the parent listing looks healthy. That fee runs $0.32 to $0.97 per unit. Together these two create a narrow window: too much inventory costs you, and too little costs you.

Beyond that, the Professional selling plan is $39.99 per month while the Individual plan charges $0.99 per item sold, and Amazon advertising averages 10-15% of revenue — with competitive categories reaching 20-25%.

1. Re-run every SKU against the 2026 fee table including the 3.5% fuel surcharge — not last year's numbers

2. Audit any SKU past 150 days in a fulfillment center before it crosses the 181-day aged-inventory threshold

3. Track days of supply at the FNSKU level, not the ASIN level, so a single variation doesn't trigger the low-inventory fee

4. Target 30-60 days of supply — below that you pay the low-inventory fee, above it you pay storage plus aged-inventory surcharges

5. Split inbound shipments across fulfillment centers yourself to cut placement fees

6. Move slow, heavy, or oversized items to FBM where FBA economics no longer clear your margin

Frequently Asked Questions

How much does it cost to start selling on Amazon in 2026?

Average startup costs for new FBA sellers run $2,500-$5,000 for initial inventory and setup. That covers the Professional plan at $39.99 per month, first inventory order, product photography, and packaging design.

How much did Amazon FBA fees increase in 2026?

Fulfillment fees rose on January 15, 2026 by an average of $0.08 per unit — less than 0.5% of a typical item's selling price. The change sellers actually feel is the 3.5% fuel and logistics surcharge added on April 17, 2026 to all US and Canada fulfillment fees.

Did Amazon referral fees change in 2026?

No. Referral fees were unchanged for 2026 and remain at 8-15% across most categories. This is the second consecutive year Amazon has left them flat.

What is the new aged inventory surcharge and how do I avoid it?

In 2026 the aged inventory surcharge starts after 181 days in a fulfillment center, down from 271 days. To avoid it, run a monthly inventory age report, flag every SKU past 150 days, and decide early whether to discount, advertise harder, or remove the stock.

What percentage of revenue do total Amazon costs represent?

Total costs — referral fees, FBA, storage, and advertising — average 25-45% of gross sales revenue. Successful sellers typically reinvest another 20-30% of revenue into inventory and advertising.

When should I switch from FBM to FBA?

Move to FBA when you sell more than 10-15 units per month per product, or when an item weighs under 2 lb and prices above $15. FBA buys you the Prime competitive advantage but costs more on slow or heavy items — especially after the 2026 fuel surcharge.

Summary

Selling on Amazon in 2026 demands precise financial planning. Referral fees are frozen, but January's fulfillment increase, April's 3.5% fuel surcharge, and the aged-inventory threshold moving to 181 days together erode margins for anyone still working off last year's numbers. Reprice every SKU against 2026 rates and build a monthly review of days-of-supply and inventory age.
