The two Amazon fees sellers confuse
Amazon takes two very different charges. The referral fee is a percentage commission on every sale (with 20% VAT on top). The FBA fee is a fixed fulfilment charge based on the product's size and weight. Many sellers price only against the referral fee and are surprised when FBA quietly erases the margin — this calculator forces both onto the same screen. For the referral side in detail, use the Amazon commission calculator.
Referral fee, FBA fee and the rest
Net profit is the sale price minus: referral fee (base + VAT), FBA fee, the 1% e-commerce withholding tax, VAT payable, and product cost. Enter each from Seller Central; the FBA fee in particular changes with the size tier, so use the exact figure for your product.
FBA or FBM?
For FBM (you ship yourself), set the FBA field to zero and enter your carrier cost as shipping. Comparing the two modes in the tool shows whether FBA's fee is worth the logistics it removes for your product.
Comparing Amazon with other marketplaces
Put the same product across channels with the marketplace profit comparison to see where it nets most before committing stock to FBA.
Method and sources
The calculator applies the rate you enter to the total the buyer pays and adds 20% VAT on top of the referral fee (official fee page satis.amazon.com.tr/ucretlendirme, read on 14 October 2026), uses the FBA fee you enter, 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, referral fee, shipping and the FBA fee (a negative result carries over and is not added to profit). Product cost, shipping and the FBA fee are entered VAT-inclusive. Referral and FBA fees must be verified in Amazon Seller Central.
