Loan commission is a fee that is calculated over and above the interest for the use of a loan. The credit commission is practically the same as the interest and is to be added to this in order to be able to assess an interest rate.
Example: 6 % interest plus 0.250 % K. per month makes 9 % total interest charge. The K. can be calculated from the credit actually used or from the credit granted; if possible, it should relate to the credit actually used.
