Definition
Interest rate that indicates the effective cost or yield of a financial product. The APRC is calculated according to a standardized mathematical formula that takes into account the nominal interest rate of the operation, the frequency of payments (monthly, quarterly, etc.), bank fees, and some operation expenses.
Further information
In the case of loans, certain items are not included in the calculation of the effective cost, such as expenses that the client can avoid by exercising the rights granted by the contract, expenses that must be paid to third parties, or expenses for insurance or guarantees (except for certain types and only if the entity requires their subscription for the granting of the loan).
The main differences between the APRC and the nominal interest rate (NIR) arise in two ways. Firstly, the APRC incorporates certain fees and expenses. Secondly, the APR takes into account the frequency of payments. It is not equivalent for payments to be made monthly or once a year, for example. In the case of monthly payments, the situation is more costly for the creditor (and therefore, the APR will be higher than the NIR for this reason). If, for example, there are no fees or expenses and payments are made once a year, the APR will be similar to the NIR.
