Amazon announced its 2027 U.S. referral and Fulfillment by Amazon (FBA) fee updates on November 5, 2026. Most changes begin January 15, 2027. Amazon says the average FBA fulfillment fee will rise $0.19 per unit, but that figure is not a reliable forecast for any one SKU: some fees rise and others fall. Brand teams should model their actual catalog before finalizing 2027 prices, media budgets and replenishment.
What changes, and when
Amazon says the fulfillment change varies by product, size and price. It is keeping the FBA fuel and logistics surcharge unchanged. On February 1, 2027, Amazon says it will remove the storage utilization surcharge and fold the aged-inventory surcharge into monthly storage fees as an age-based rate. It expects flat or lower storage fees for inventory that turns in under six months and higher fees for older inventory.
The low-inventory-level fee also changes February 1. Amazon says it will apply when inventory falls below 28 days of supply, using actual shipments in the four weeks before and after the assessment date. That look-forward element matters for a SKU with a temporary demand spike or an end-of-life runout, but it is no reason to deliberately understock a healthy product.
Where the average hides the decision
Start with top-volume SKUs and products near a contribution-margin threshold. Export current fees, then compare them with Amazon's new Fee Change Comparison dashboard in Profit Analytics or model scenarios in the Revenue Calculator. Include the unchanged surcharge, referral fees, expected advertising cost and realistic return allowances. Repeat the calculation for slow-moving stock; the new storage structure could change the economics of a broad safety-stock policy.
For each SKU, record a 2027 contribution estimate and the action owner. Price changes, assortment changes and replenishment decisions should follow that calculation rather than a blanket $0.19 adjustment. This is Etail Rocket's operating recommendation, not an Amazon forecast of your account's outcome.
What to do before January 15
- Pull the account-level and item-level fee comparison, then validate the highest-impact SKUs.
- Separate fulfillment changes taking effect January 15 from storage and low-inventory rules taking effect February 1.
- Stress-test price, ad spend and days of cover for margin-sensitive items.
- Assign owners to aging inventory and to SKUs whose planned stock may sit near 28 days of supply.
