Amazon FBM Fees Calculator

With Fulfilled by Merchant (FBM), you store and ship orders yourself, so Amazon charges no fulfillment fee. The main cost is the referral fee, which is 15% of the item price for most categories. To work out what you keep, subtract that fee, your cost of goods, and your shipping cost from the sale price. This calculator does the math for you when you click Calculate.

On a $100 sale, a 15% referral fee is $15, which leaves you $85. Your actual profit is that $85 minus what you paid for the item and what you spend on shipping.

Amazon may apply the referral fee to the total sale amount, including buyer-paid shipping and tax. This calculator applies the 15% fee to the product price only, so treat the result as an estimate. Enter what you pay to ship the order in the Shipping Cost field. It is subtracted from your profit.

Yes. 15% is the most common referral rate, but rates vary by category and promotion, and some categories add a minimum fee per item. Your selling plan can add costs too. Confirm current rates in Seller Central before you price your products.
