What actually remains from an Amazon sale
The referral fee is only the first cut. From the sale price, Amazon takes commission with 20% VAT added on top, you pay shipping, the state withholds a 1% e-commerce withholding tax, and you remit the VAT payable (sales VAT minus the deductible VAT on your costs). Only after all of these do you see the real net profit — which is what the calculator above isolates.
Why the VAT-on-top model matters
On Amazon a 15% referral fee is not 15% of the sale; the 20% VAT on top makes it about 18%. If you priced your product using Trendyol's VAT-inclusive logic, your Amazon margin is thinner than you think. Break down the commission line in detail with the Amazon commission calculator.
Selling with FBA
If you fulfil through Fulfilment by Amazon, the referral fee is not the whole story: storage and per-unit fulfilment fees come on top and change your real margin. Layer those costs in with the Amazon FBA calculator before you decide on a price.
Pricing to a target margin
Use the calculator in reverse: fix your cost and rates, then adjust the sale price until the net margin hits your target. To understand the difference between margin and markup, see the profit margin calculator. Before joining a deal or coupon, check that the discounted price still clears break-even.
Comparing with other marketplaces
The same product nets differently on each channel. Put Amazon, Trendyol, Hepsiburada and n11 side by side with the marketplace profit comparison.
Method and sources
The calculator applies the rate you enter to the total the buyer pays and adds 20% VAT on top of the commission (official fee page satis.amazon.com.tr/ucretlendirme, read on 14 October 2026), takes the 1% withholding tax on the VAT-excluded sale amount, and calculates VAT payable as sales VAT minus the deductible VAT on product cost, commission and shipping (a negative result carries over and is not added to profit). Product cost and shipping are entered VAT-inclusive. Referral fees and the exact VAT position must be verified in Amazon Seller Central and your accounting summary.
