At a glance

The commission Amazon charges on every sale, summed for the period. Referral fees are the percentage Amazon takes off the top of each ordered-product sale, charged on every unit whether you fulfil through FBA or FBM. For most categories the rate sits around 15% of the item price, with a per-item minimum. This is the single biggest deduction between your ordered product sales and what actually lands in your settlement, so finance checks it alongside FBA fees every settlement cycle.

What it counts	The sum of Amazon referral fee line items across all orders settled in the window, sourced from the settlement and finances data. Referral fee is Amazon’s commission on the item price (and usually the shipping you charge), distinct from FBA fulfilment fees.
Fulfilment scope	Charged on both FBA and FBM orders. Referral fee is a selling fee, not a fulfilment fee, so switching a SKU from FBA to FBM does not avoid it.
Rate framing	Most categories are around 15% of the item price; some run lower (around 8% for some electronics) and some higher. Many categories carry a per-item minimum referral fee (commonly a small fixed floor) that applies when the percentage would fall below it on low-priced items. Do not treat the rate as a flat 15% across your catalogue.
What it is charged on	The item price, and in most categories the portion of shipping you charge the buyer. Gift-wrap charges can also attract referral fee in some categories.
Relationship to FBA fees	Referral fee is separate from FBA Fees (pick, pack, weight handling) and FBA Storage Fees. Total Amazon deductions on an FBA order are referral + FBA fulfilment + storage + any ads.
Refund handling	When an order is refunded, Amazon returns a portion of the referral fee (less a refund administration fee in many cases). Whether a given period nets the refunded referral back depends on when the refund settles relative to the window.
Currency	Each marketplace settles in its own currency. A seller live in multiple Amazon marketplaces should read this per marketplace, the card does not perform FX normalisation.
Time window	30D (the selected period)
Alert trigger	Configurable threshold on referral-fee movement
Roles	owner, finance

Calculation

Calculated automatically from your Amazon Seller Central data. See the At a glance summary above for what the metric tracks and the worked example below for a typical reading.

Worked example

A UK home-and-kitchen seller on amazon.co.uk, mixed FBA and FBM. Period: 02 Apr 26 to 01 May 26 (30D). Figures below are illustrative.

Category band	Units	Avg item price	Referral rate (illustrative)	Referral fee
Kitchen, mid-price	3,200	£24	15.0%	£11,520
Home decor	1,450	£18	15.0%	£3,915
Small accessories (hit per-item floor)	980	£4.50	per-item minimum applied	£294
Electronics accessory	540	£32	8.0%	£1,382
Referral Fees (this card)	6,170	mixed	blended	£17,111

Blended referral rate  =  £17,111 referral  /  ~£113,000 ordered product sales  ≈  15.1%
Per-item floor effect  =  the 980 low-price accessories paid a higher effective rate than 15%
                          because the fixed minimum dominated on a £4.50 item.

Five things to notice:

1. The blended rate is not the headline category rate. Even though most lines sit at 15%, the per-item minimum on cheap accessories pushes their effective rate well above 15%, while the 8% electronics line pulls the blend down. The true blended rate (about 15.1% here) is what matters for margin planning, not the sticker rate.
2. Low-price SKUs are quietly expensive. The £4.50 accessory paid a fixed minimum referral fee that can represent a much larger share of the item price than 15%. Sellers with a long tail of cheap ASINs should check whether those SKUs are profitable after referral plus FBA fees.
3. Referral applies on FBM too. Roughly a third of these units shipped FBM, yet every one of them still paid referral fee. There is no referral saving from self-fulfilling; the only fee you avoid by going FBM is the FBA fulfilment fee.
4. Refund timing moves the number. A handful of orders refunded late in the window returned most of their referral fee, but a refund administration fee was retained. If you compare this card to a raw 15% of sales, refunds explain part of the gap.
5. This is the biggest single deduction. At roughly 15% of ordered product sales, referral fee dwarfs most other Amazon charges. Pair it with FBA Fees and Fees % of Revenue to see total Amazon take.

Sibling cards merchants should reference together

Referral fee on its own is just a cost line. Pair it with these to understand margin:

Card	Why pair it with Referral Fees
FBA Fees	The other major deduction on FBA orders. Referral + FBA fulfilment is most of what Amazon takes before storage and ads.
Fees % of Revenue	The ratio version. A creeping fee % usually means mix shifted toward higher-fee categories or toward low-price SKUs hitting the per-item floor.
Per-ASIN Fee Outliers	Finds the specific ASINs where fees are eating margin, often the cheap accessories paying the minimum referral fee.
Net Revenue (after fees + refunds)	Total Revenue minus referral, FBA, storage and refunds. This is the number that actually banks.
Total Revenue	The gross figure referral fee is charged against. Referral ÷ Total Revenue is your blended commission rate.
FBA Storage Fees	The third FBA cost line. Add referral + fulfilment + storage for the full FBA cost stack per SKU.

Reconciling against Amazon Seller Central

Where to look in Seller Central:

The closest Amazon-native views are:

Reports → Payments → Transaction view (filter to fee type) for the per-order referral fee lines, and Reports → Payments → Date Range Reports → Summary for the period total of referral fees.

For a forward-looking per-ASIN view, the Fee Preview report (Inventory reports) estimates referral and FBA fees per SKU. That report is an estimate; the authoritative figure is always the settled transaction in Payments.

Timing, settlement, and reporting-lag table:

Topic	Detail
Timezone	Seller Central reports in the marketplace’s local time / the account setting. Vortex IQ uses UTC for period boundaries, so orders near midnight on the boundary days can fall on different sides. The effect averages out over 30D.
Settlement timing	Referral fee is deducted at the point of sale but reconciled in the settlement report, which runs on a rolling cycle (commonly every 14 days). A fee charged near the period edge may settle in the next cycle, so a single 30D window can lag the true accrued referral slightly.
Refund administration fee	When Amazon refunds referral on a returned order it usually keeps a refund administration fee. Reconcile net-of-refund referral, not gross, when comparing to a flat percentage of sales.
Reporting lag	Settlement-derived fee data is typically a day or two behind real time. “Today” may understate referral fee until the relevant transactions settle.

Why our number may legitimately differ from Seller Central:

Reason	Direction	Why
Settlement window vs calendar window	Either direction at the edges	Amazon’s settlement cycles do not align to calendar months. A 30D calendar window can include or exclude fees that Amazon books in an adjacent settlement.
Refund netting	Ours may differ near refunds	Whether a refunded referral fee credits back inside the window depends on refund settle date. A return processed just after the window keeps the original fee in this period.
Per-item minimum rounding	Tiny	Effective rate on low-price SKUs is dominated by the fixed minimum; small rounding differences accumulate across thousands of units.
Multi-marketplace currency	Shape mismatch	If you sell in several marketplaces, Seller Central reports each in its own currency. The card does not FX-normalise; read per marketplace.

Cross-connector reconciliation against other connectors the same seller may run:

Card	Expected relationship	What causes legitimate divergence
amazon.fba_fees	Complementary, not overlapping. Referral and FBA fulfilment are separate fee types charged on the same orders. Sum them for total Amazon take on FBA orders.	FBM orders pay referral but no FBA fulfilment fee, so the two cards diverge by the FBM share.
amazon.net_revenue_after_fees_refunds	Net is gross minus this and other fees. Referral is the largest component subtracted to get net.	Refund timing and ad spend also move net, so the relationship is not a clean subtraction in any single window.

Known limitations / merchant FAQs

Is referral fee the same as the FBA fee? No. Referral fee is Amazon’s commission on the sale, charged on FBA and FBM orders alike. The FBA fee is the fulfilment charge (pick, pack, weight handling) and applies only to FBA orders. They are separate line items and you pay both on an FBA order. See FBA Fees.

What rate does Amazon actually charge? Most categories are around 15% of the item price, but it varies. Some electronics run lower, some categories higher, and many carry a per-item minimum that applies on cheap items. Always read the blended rate from this card (referral ÷ ordered product sales) rather than assuming a flat 15%.

Why is my effective rate above 15%? Almost always the per-item minimum on low-priced SKUs. On a very cheap item the fixed floor can be a far larger share of the price than 15%. If your catalogue has a long tail of low-price ASINs, check Per-ASIN Fee Outliers.

Do I get the referral fee back on a refund? Mostly. Amazon refunds the referral fee on a returned order but usually keeps a refund administration fee. Net-of-refund referral is slightly higher than a naive (sales x rate) minus (refunds x rate) calculation because of that retained admin fee.

Can I reduce referral fees? Not the rate itself, that is set by category. You reduce the absolute fee by raising prices where elasticity allows, by moving low-price SKUs into bundles so they clear the per-item floor more efficiently, or by re-categorising a mis-classified ASIN into a correct, lower-fee category where applicable.

Why doesn’t this match a flat 15% of my sales? Three reasons: per-item minimums push some SKUs above 15%, some categories sit below 15%, and refund netting plus settlement timing shift the booked total. The blended rate on this card is the accurate read.
