Search for Kogan's seller fees and most of what comes back skips the number you came for. There's a reason: Kogan doesn't publish a standard commission. Your rate is set in your seller agreement, and each payout comes with a separate commission invoice that breaks your fees down.
Kogan does publish the rest of what decides your margin — a payment processing fee on every order, a performance penalty that can add 5% to a month's fees, and the dates you get paid. This guide covers each one from Kogan's own seller help centre, read on 17 October 2026, and shows how to work out what you keep once you know your rate. The calculator above takes Kogan's two fees in its Marketplace fees and Payment fees boxes.
Revenue and every variable cost for the period.

Commission on each sale, at the rate in your seller agreement. Kogan's public help centre gives no standard rate and no rate card by category, so treat any figure you see quoted online as someone else's deal.
A Merchant Payment Processing Fee of 20c plus 1.39% on every order. Kogan describes it as non-refundable, and it covers every way a customer can pay on Kogan.com — cards, PayPal, Afterpay, Zip, Apple Pay, Qantas points and the rest — so it doesn't change with how the buyer pays.
Costs you opt into: Kogan Ads, charged per click and taken out of your payouts monthly, and Kogan First discounts, which you fund. And one cost you don't choose but can avoid: the performance penalty below.
Kogan doesn't fulfil marketplace orders. You ship them yourself — with free, flat-rate, free-over-a-threshold or weight-and-location shipping — and Kogan points businesses without online fulfilment to its supplier programme instead. So delivery is your cost too, and on Kogan it can be bigger than the fees.
The fixed 20c makes the fee heavier on small orders. On a $20 order it's $0.48, or 2.4% of the order. On $50 it's $0.90 (1.8%). On $200 it's $2.98 (1.49%).
Because Kogan calls it non-refundable, an order you later refund still costs you the fee. Count it in your returns cost, not just your sales cost.
Kogan tracks two numbers: your cancellation rate (the share of orders you cancel) and your delay rate (the share of orders whose shipment details aren't provided within your handling time). If cancellations go over 3%, delays go over 5%, or the two together go over 8%, Kogan charges an additional 5% fee on the gross sales of the preceding calendar month.
That's 5% of all of the month's sales, not just the late orders. On a $20,000 month it's $1,000. Kogan can also apply the penalty for compliance breaches — listing a product against its Prohibited & Restricted Products policy, Product Compliance Guide or electrical safety requirements, or not acting on a recall in time — assessed per occurrence.
Kogan's service level agreement expects better still on cancellations — a rate of 1.5% — alongside a late-shipment rate of 5% and 95% of customer tickets answered within 4 business hours and resolved within 3 days. Orders not marked as dispatched within 30 days are cancelled automatically; the customer is refunded and you aren't paid.
Kogan pays twice a month, on the 8th and the 22nd, shifting slightly around weekends and public holidays. The 8th covers orders dispatched from the 15th to the end of the previous month; the 22nd covers orders dispatched from the 1st to the 14th.
Only orders with valid tracking uploaded get paid, and the clock runs from dispatch, not from the sale. Money from an order lands somewhere between about 8 and 24 days after you dispatch it. Each payment comes with an emailed remittance and a separate commission invoice, and any Kogan Ads spend is deducted from your payouts monthly.
Kogan says it acts as the intermediary between you and the customer. When a customer asks, you provide the GST tax invoice — for the full value of the sale — and Kogan says its commission is a cost of the transaction that shouldn't appear separately on that invoice. Kogan's marketplace API also marks every order amount as tax-inclusive.
So if you're registered for GST, 1/11 of each order's value is GST you owe the ATO (GST is 10%, and the GST inside a GST-inclusive price is the price divided by 11). The ATO requires registration once your GST turnover reaches $75,000. This isn't tax advice — your accountant has the final word.
Kogan doesn't publish a rate, so this example assumes a 10% commission charged on the order value. That's a placeholder, not Kogan's rate — use the one in your agreement.
A $59.95 order with free shipping, from a GST-registered seller. GST to the ATO is $5.45. Commission at 10% is $6.00, and the payment fee is $1.03. The product costs $22.00, the courier $9.50 and packaging $0.80. That leaves $15.17, about 28% of the ex-GST price. Add $2.50 of Kogan Ads per order and it's $12.67, or 23%.
Two things stand out. Kogan's own fees come to $7.03 here, but shipping costs $9.50 — on a marketplace where you deliver every order yourself, shipping can cost you more than the marketplace does. And at 300 orders a month, the product makes about $3,800 after ads, while a penalty month would cost about $900: 5% of nearly $18,000 in sales, close to a quarter of the profit.
To run your own numbers in the calculator above, enter a month: revenue (ex GST if you're registered), product cost, shipping, your commission in Marketplace fees, the payment fee in Payment fees (20c per order plus 1.39% of order value), Kogan First discounts in Discounts, and Kogan Ads spend in Advertising.
Kogan First is Kogan's paid membership for shoppers. You can offer members a lower price, either per product through the Kogan First Price field or as a blanket percentage for your store; where both apply, Kogan uses the bigger discount. In return your products can join First-only promotions and carry the badge members can filter by. The discount comes off your price, so it comes out of your margin.
Kogan Ads is cost per click, with daily campaign and monthly account budgets. Ads appear in search results, customer emails, Google Shopping and the recommendation carousels on product pages, and they're billed after the fact, out of your payouts. Price it like any marketplace ad: the most you can spend per order is what's left after commission, the payment fee, GST, product cost and shipping.
Kogan also says that popularity, price competitiveness, shipping speed and seller performance are among the factors that decide how your products are displayed — so fast, reliable dispatch earns you visibility as well as keeping you clear of the penalty.
It's a growing channel. In Kogan.com's results for the year to June 2026, filed with the ASX on 24 August 2026, Kogan.com's marketplace revenue — the fees it earns from sellers — rose 20.3% to $35.4 million, which Kogan put down to more sellers and more marketing. Kogan First, the membership behind those member discounts, brought in $57.0 million.
A Kogan listing can also reach Dick Smith and Matt Blatt in Australia, and Kogan NZ and Dick Smith NZ if you meet Kogan's New Zealand seller requirements. It's application-based: you tell Kogan about your brand and apply through its marketplace page.
Whether it's worth it for you comes down to two checks. Does your price cover your commission, the 20c + 1.39%, GST and your own shipping with room left for ads? And can you dispatch reliably enough to stay well under 3% cancellations and 5% delays? If both hold, Kogan is a real second or third channel for an Australian seller.
Kogan's order feed carries prices but not fees — the one fee field in its marketplace API is marked as not used — so your profit always needs your commission rate added on top. Dash Captain reads Kogan read-only and shows your sales, orders and best sellers alongside your other channels. Kogan Marketplace is in early access.
Commission at the rate in your seller agreement, plus a Merchant Payment Processing Fee of 20c + 1.39% on every order. Kogan Ads (cost per click) and Kogan First member discounts are optional costs on top, and a 5% penalty on a month's gross sales applies if your cancellation or delay rate goes over Kogan's limits. Read from Kogan's seller help centre on 17 October 2026.
Kogan doesn't publish one. Your rate is set in your seller agreement, and each payout comes with a separate commission invoice detailing your fees. Treat any rate you see quoted online as someone else's deal.
Kogan's public seller help centre doesn't list one: the fees it publishes are tied to orders (commission and the payment processing fee), plus optional ads and promotions. Your seller agreement is the final word.
Twice a month, on the 8th and the 22nd. The 8th covers orders dispatched from the 15th to the end of the previous month, and the 22nd covers the 1st to the 14th. Only orders with valid tracking are paid.
An additional 5% fee on the previous calendar month's gross sales, applied if your cancellation rate goes over 3%, your delay rate over 5%, or the two combined over 8%. It can also apply for listing breaches such as prohibited products, compliance failures or recalls not actioned in time.
If you can fulfil online orders yourself, you can apply through Kogan's marketplace page by telling Kogan about your brand. If you can't fulfil orders, Kogan points you to its supplier programme instead.

Every Amazon.com.au seller fee in AUD: referral fees of 6% to 15% for most categories with no minimum, FBA fees from $4.55, storage per cubic metre — and how GST changes what you keep. With a worked example.
Amazon and Shopify charge completely different fees, so comparing their revenue tells you nothing about which one actually makes you money. Here's the contribution-margin method that compares them fairly, a worked example, and three ways the comparison quietly goes wrong.
Revenue is vanity; profit is sanity. Walk the profit ladder — gross, contribution and net — learn which costs belong where, how discounts, shipping and returns bite, and how to find the numbers that tell you if you're actually making money.
Profit margin is the share of each sale you keep as profit. Learn the profit margin formula, how it differs from markup, and what a healthy margin looks like — then run your own numbers.
