Calculate Amazon Fees: When selling products on Amazon, it is crucial to understand the fees associated with the platform. To calculate these fees, you need to consider two main components: the referral fee and the variable closing fee. The referral fee is a percentage of the item’s sale price, which varies depending on the category. The variable closing fee is applicable to media products, such as books or DVDs. By multiplying the sale price by the referral fee and adding the variable closing fee (if applicable), you can determine the total fees associated with selling your product on Amazon.
