Diablo 3 offers two kinds of Auction House - gold-based auction house and real-money auction-house. Both AHs charge transaction fee (and sometimes transfer fee) for selling item. On GAH it is always 15% fee. On RMAH fee depends from item type (stackable or armor/weapon), deposit funds option (Battle.net balance or PayPal) and currency (USD, EUR, GBP, RUB, MXN, BRL, ARS, CLP, AUD).
Sounds complicated? Don't worry - Diablo 3 Auction House Fee Calculator will count for you how much you will get charged for selling items and will show you what price you need to setup on AH to get fixed amount of cash or gold.
