Amazon FBA Calculator for Australia: Fees and Profit per Unit in A$

This calculator estimates the profit on one unit sold through Fulfilment by Amazon (FBA) on Amazon.com.au. Enter the price your customer pays including GST, your category referral rate, the FBA fulfilment fee for your size tier, storage, product cost and inbound shipping. It returns the fees and what is left, in A$. Defaults come from Amazon's published rates as of October 2026, for example A$7.34 FBA fulfilment for a 0 to 250 g parcel on items at A$13 or more, excluding GST.

Which rates are the defaults?

• Selling price and product cost. Placeholders. They are not Amazon rates. Price includes GST. Product cost and inbound shipping are entered excluding GST.
• Referral rate. 13%, which is Amazon's published rate for Home and Kitchen. Amazon states there is no minimum or maximum referral fee. Other categories differ and some change at a price point, such as Beauty, Health and Personal Care at 8% up to A$20 and 13% above. Use Amazon Australia referral fees by category and overwrite the field.
• FBA fulfilment fee. A$7.34, for a parcel of 0 to 250 g on an item priced A$13 or more, excluding GST. Items under A$13 have a lower column (A$6.43 for that tier). Amazon reduced selected fulfilment fees effective 10 June 2026, and the table does not label which rows moved, so confirm your row in Amazon Australia FBA fees and your fee preview.
• Storage. A$37.00 per cubic metre per month for standard-size items from January to September, and A$51.80 from October to December, excluding GST. Amazon bills storage on daily average volume in cubic metres. The default unit volume of 0.005 m³ is 5,000 cm³, for example a 20 x 15 x 16.7 cm box.
• GST rate. 10%. Amazon says Australian GST applies to most items sold on Amazon.com.au, and eBay's fee page describes the Australian GST as 10%. Confirm with the ATO.

How does the calculation work?

GST is 1/11 of a GST-inclusive price at a 10% rate, so on A$40.00 it is A$3.64 and revenue excluding GST is A$36.36. The referral fee is the percentage you enter. Amazon says the fee applies to the total sales price, including delivery and gift wrapping. The pricing page does not say whether GST sits inside that base, so the default is the cautious one, the GST-inclusive price. If your Seller Central fee preview shows a lower fee, switch the option. FBA fulfilment is a flat A$ amount per unit by size tier, and it covers picking, packing, shipping, customer service and returns handling. Storage is volume times months times the monthly rate.

With the defaults, a A$40.00 item pays A$5.20 referral, A$7.34 fulfilment and A$0.37 storage, which is A$12.91 in fees. After A$10.00 product cost and A$1.00 inbound it leaves about A$12.45 per unit before ads and returns.

Amazon quotes its fees excluding GST. Whether GST is added to your fee invoices, and how you claim it, depends on your account and registration. Confirm with the ATO or a registered tax agent. This is general information, not tax advice. The profit calculator covers GST treatment, ads and returns.

What does this calculator leave out?

• Closing fee. Amazon lists no fixed closing fee on the Professional plan, but A$0.99 per item excluding GST on Individual, and A$1.00 per media item on all plans. Add it under inbound if it applies.
• Aged and long-term storage. Items held over 365 days attract extra fees, and the aged-inventory surcharge starts at 271 days. Keep the months input well below that. See storage fees.
• Returns and removals. Amazon publishes these amounts inside Seller Central. See returns fees and removal and disposal fees.
• Inbound placement fee. It exists in Australia, but the amounts are not on a public page.
• Advertising. Not included. Use the profit calculator.
• Peak storage rates. Change the storage rate to 51.80 for October to December.

FAQ

Is this the official Amazon Australia FBA calculator? No. Amazon provides its own revenue calculator and fee preview inside Seller Central. This page is an independent planning tool built on Amazon's published rates. For the exact fee on a live listing, use the fee preview in your account.

Which FBA fulfilment fee should I enter? The one for your size tier, weight and price band in Amazon's table, which has columns for items at A$13 or more and under A$13. The default A$7.34 is only one row. Look yours up in Amazon Australia FBA fees.

How is FBA storage calculated? By daily average volume in cubic metres, at A$37.00 per cubic metre per month from January to September for standard-size items. Multiply unit volume by months in stock and the monthly rate.

Does the calculator include GST? It takes GST out of your GST-inclusive price at an editable 10%, and treats Amazon fees as quoted, excluding GST. It does not model GST credits. Confirm your treatment with the ATO or an accountant.

What referral rate should I use? The one for your category in Amazon's published table, which ranges from 5% to 15%. The 13% default is only an example. Replace it.

Does it include the June 2026 fee reductions? Only if the fulfilment fee you enter does. Amazon reduced selected FBA fees effective 10 June 2026, but the public table does not label the changed rows. Check your fee preview.
