Credit analysis refers not only to an assessment of a client's overall credit capability, but also to a process of determining the maximum credit amount a buyer can bear. Before approving credit, banks make a credit analysis i.e. a calculation of the credit capability of the debtor. This paper explains the notion and types of credit as well as the significance of credit in the economy. Credit is a particular amount of money that is approved to the credit user for a particular amount of time and at a particular price. Also, the crediting process is explained and the key steps in the process of crediting are listed, as well as the parts of the credit agreement. Throughout, the paper covers concrete examples of requests for commercial, consumer and mortgage credits. To determine the probability that the debtor will not be late with paying back of the loan, i.e. to discern the good from the bad, a scoring method will be used. At the end of the paper it is concluded, that although credit today is available to almost everybody, the entire process of crediting is in fact complex and demanding.
