In royalty agreements the royalty fee, which is a type of mining rent, is paid by the royalty payer to the licensee in return for the right to operate the mine. The royalty fee, which can be determined in several ways by the parties, is paid even if the production is not carried out in the contracted amount. This study addresses the general characteristics of royalty agreements, the status of the royalty fee under various possibilities, and whether the fee should be classified as a period expense or added to the product cost.
