How Amazon FBA Fees Are Calculated in 2026

Selling on Amazon through Fulfillment by Amazon (FBA) means Amazon stores, packs, and ships your products to customers. While FBA saves time and unlocks Prime eligibility, it comes with several fee categories that directly affect your profit margins. Understanding these costs before listing a product is essential for cross-border sellers sourcing from overseas manufacturers.

The three primary FBA fee types are referral fees, fulfillment fees, and storage fees. Referral fees are a percentage of your item's sale price and vary by product category — for example, electronics typically carry lower rates than clothing. Fulfillment fees depend on your product's size tier (Small Standard, Large Standard, Small Bulky, Large Bulky, or Extra-Large) and shipping weight, with separate price bands for items under $10, $10–$50, and over $50. Switch to FBM mode to compare merchant-fulfilled economics (referral fee + your own outbound shipping, without FBA fulfillment or storage fees).

Starting April 17, 2026, Amazon applies a 3.5% fuel and logistics-related surcharge on top of the base FBA fulfillment fee. This surcharge is calculated on the fulfillment fee only — not on your sale price or referral fees. Factor it into every unit economics model for 2026 and beyond.

Amazon applies peak-season storage surcharges from October through December each year. Additionally, the aged inventory surcharge begins at 181 days in fulfillment centers, with escalating tiers up to 456+ days. If you plan inventory for Q4, factor these higher costs into your pricing strategy well in advance.

To calculate your true profit, subtract all Amazon fees plus your cost of goods and inbound shipping from your sale price. The break-even price tells you the minimum sale price needed to cover all costs without losing money. Use this calculator as a starting point, then verify exact fees in Amazon Seller Central's Revenue Calculator.

Amazon updates its fee schedule annually, typically announcing changes in December for the following year. Always check the latest Seller Central fee preview before making major inventory decisions. This tool uses configurable fee tables that can be updated as new rates are published.
