Additional repayments made on Internet Banking or in the ABN AMRO app will be debited from your current account immediately. On the next working day, you will see on your loan overview page that your outstanding debt has gone down.  If you are making an additional repayment by transfer, it will take 3 working days for the repayment to be processed.
As soon as your repayment has been processed, you will only pay interest on the new, smaller debt. This means your repayments will end sooner.
