This is the cost of capital provided by credit providers . Effective annual interest must be stated in the consumer credit contract. This interest is the cost of the consumer credit in percent per annum. Providers rarely state an exact interest rate, but usually define a range of interest. Actual interest rates as agreed in the contract are somewhere between the minimum and maximum amount of this range and depend on a verification of creditworthiness.
