eBay charges Basic Fees such as Insertion Fees and Final Value Fees. An Insertion Fee is charged when you list an item on eBay.
If the item sells, you're charged a final value fee. Final value fees are calculated based on the total amount of the sale
and are charged per item. The total amount of the sale is the final price of the item, shipping charges, and any other amounts you may charge the buyer. Sales tax is not included.
There are also Optional Fees (Advanced listing upgrade fees and Supplemental service fees) if you add advanced listing upgrades to your listing or use supplemental services. See details here.
