Why isn’t the balance on my personal loan decreasing?

If you have a temporary special agreement, the agreed amount may be so low that it only covers interest and fees. 

Therefore, you will notice that your debt does not decrease while you have this agreement.

Personal loans are organized as annuity loans, meaning that you pay a fixed amount each month during the entire loan term. Early in the loan, when the balance is largest, the payment contains a higher proportion of interest and a smaller portion of principal. As the loan progresses, this gradually shifts to lower interest and higher principal repayment.
