The fee charged on postal orders by the post office is called "poundage". Poundage is a fee that is added to the total value of the postal order. It is a small percentage or fixed amount that the post office charges for providing the service of issuing and handling the postal order. The purpose of the poundage fee is to cover the costs incurred by the post office in processing and delivering the postal order. This includes administrative expenses, handling and transportation costs, as well as providing security for the transaction. It is important to note that the poundage fee is not the same as interest or brokerage. Interest refers to the additional amount of money earned on an investment or loan, which is not relevant to postal orders. Brokerage, on the other hand, is a fee charged by a broker for arranging a transaction between a buyer and a seller, which is also not applicable to postal orders. Therefore, to summarize, the fee charged on postal orders by the post office is called "poundage." It is a fee added to the total value of the postal order to cover the costs of processing and delivering the order.
