Amazon FBA fee schedule: every version, every effective date

2026 Amazon FBA fee changes: summary table

The version stamp is the trust artifact.

Fee calculators go stale on the day Amazon reprices. If the tool you're using doesn't show its sources, you can't tell whether the number it just gave you is from this month or last year. Every CrateFit result shows the version label and the effective date next to the total. This page is the full index of those versions.

Frequently asked questions

When did Amazon change FBA fees in 2026?

Twice. January 15, 2026 for the structural restructuring (weight bands, split size tiers, raised defect fees) and April 17, 2026 for the 3.5% fuel surcharge on fulfillment fees.

What is the Amazon FBA fuel surcharge?

A 3.5% multiplier Amazon added on April 17, 2026. It applies to base fulfillment fees only. It does not apply to placement fees, referral fees, storage fees, or defect fees. On a $6.00 base fulfillment fee, the surcharge adds $0.21 per unit.

How much did defect fees go up on January 15, 2026?

Defect fees rose from a range of $0.02 to $0.07 per unit to a range of $0.32 to $5.72 per unit. Roughly 16× on the most affected SKUs. A single defect can now exceed the margin on low-ASP items.

Where does the fee data come from?

Amazon's Seller Central fee schedule pages, the official announcements, and the FBA revenue-calculator API where applicable. Every version card links the primary source.

What happens when a shipment spans a fee-change date?

The shipment stores the version it was computed against when you saved it. The effective date is also stored. Amazon applies the schedule current on the day the shipment is billed; we show you both.

Can I pin a calculator to an older version?

Not in the public calculators. They always use the current version. In the paid app, you can choose which version to run against (useful for auditing a past shipment or for a what-if comparison).

What counts as a version?

Any effective-date change Amazon announces. If Amazon changes a single fee row and leaves the rest in place, it is still a new version. We version the whole schedule, not individual rows, so receipts stay reproducible.

How fast do versions go live after Amazon announces?

We target same-day for announced changes. The schedule is a flat data table, so updates do not require a code deploy. The January 15 restructuring and the April 17 fuel surcharge were both reflected within 24 hours of public announcement.

Is this the same fee schedule the paid app uses?

Yes. One table, two consumers.
