Amazon Referral Fee Change: Our Rate Went From 5.6% to 13%

✨ Written with AI assistance from our own settlement data, and reviewed by Avanta Global EOOD before publication. Learn more

Short answer: on our own Amazon Australia listing, the referral fee rose from about 5.6% to exactly 13.0% of the item price between 14 and 16 July 2026. Thirteen percent is the published Office Products rate. It added about A$2.28 per unit in fees and cut our break-even ACoS by roughly seven points. We found it in the settlement report, a month after it happened.

This is not a survey of the market. It is one listing, measured line by line, and the method at the end works on any seller's account.

What we measured

We sell one product on Amazon.com.au: a bundle of bubble mailers (Office Products category, fulfilled by Amazon). Every figure below comes from the settlement line items Amazon posts to our account for that SKU, from 27 May to 28 September 2026. For each order we divided the Commission fee by the item price the buyer paid.

Period	Orders	Units	Referral fee (% of item price)	Referral fee per unit
27 May – 14 Jul 2026	76	104	5–6% (median 6%)	A$1.97
16 Jul – 28 Sep 2026	320	439	13.00% (10th–90th percentile: 13.00–13.01%)	A$4.25

After the switch the rate barely moves. Nine orders in ten land at 13.00% or 13.01%, whatever the price, the quantity or the promotion. A flat rate that exact reads like a fee schedule, not noise.

What Amazon's published schedule says

Amazon Australia's published referral fees list 13% of the total sales price for Office Products. The rate we pay now matches it to the second decimal.

That makes the earlier period the unusual one. For seven weeks we paid 5–6%, well below any rate published for this category.

What we do not know

The settlement shows what we were charged. It does not show why the earlier rate was lower. Amazon Australia runs New Seller Incentives. But the incentive published there is a separate credit on branded sales, and our listing is unbranded; what fell was the commission line itself. We have not found a document that explains a 5–6% rate on this listing. So we are not naming a cause.

For a seller the practical point is the same either way. Your referral rate can change without anything in your workflow telling you, and the settlement is where it shows up first.

What it cost

At our list price of A$34.99, 13% is A$4.55 per unit, against about A$1.96 at the old rate. Across the 439 units sold after the switch, we paid about A$1,000 more in referral fees than the old rate would have cost.

The larger effect is on advertising. Break-even ACoS is the share of the price you can spend on ads before a sale stops contributing:

• Item price A$34.99, minus FBA fulfilment A$10.85, minus product cost A$7.40
• At the old ~5.6% rate: about A$14.78 contribution → break-even ACoS ~42%
• At 13%: about A$12.19 contribution → break-even ACoS ~35%

Our ACoS did not change the day the fee did. The bar it is measured against dropped by seven points. A campaign that was comfortably profitable in June could be losing money in August with an identical dashboard.

The mistake we made first

We measured the referral rate on 17 July, one day after the switch, averaged across all history, and recorded 5.63%. That number was not wrong. It was already out of date, because nearly every order in the average came from before the change.

We used it for a month. The fix was to split the same data by posting date, which put 5.63% on one side and roughly 13% on the other.

The lesson: one average across a fee change describes neither period. Group by date first, then average.

How to check your own referral rate

You can do this from the settlement report in Seller Central, without any tool:

1. Download your settlement reports as flat files for the last few months.
2. Keep the order rows. For each order, add up ItemPrice → Principal and Promotion → Principal (the item price after discounts), and take ItemFees → Commission.
3. Filter on the amount type and the amount description together. Principal appears under both ItemPrice and Promotion, so filtering on the description alone counts the item twice and makes your rate look lower than it is.
4. Divide commission by item price, per order, and group the results by week.

If the weekly figure steps up or down, the date of the step is your fee change. If it sits flat at your category's published rate, you are paying the schedule.

AgentXray reads the same settlement lines and shows the referral rate per SKU and per marketplace. When the rate moves, every profit and break-even figure moves with it, because they come from the report Amazon pays you from.

FAQ

Is the Amazon Australia referral fee charged on the price including GST? The published schedule applies the percentage to the total sales price. On our orders, 13% matched the item price the buyer paid, which on Amazon.com.au includes GST.

Did Amazon raise the Office Products referral fee in July 2026? We have no evidence of a schedule change. Our rate moved to the published 13%; the earlier, lower rate is the part we cannot explain.

How often should I check my referral rate? Whenever you set a price or an ad target, and at least once a month from the settlement. Fees are an input to both decisions, and a rate is only current as of the last report you read.
