The unpaid part of the minimum carries late interest from the due date and the rest carries the purchase rate. Rates are the central bank maximums, plus 15% KKDF and 15% BSMV. Banks accrue daily; this is a one-month estimate.

How it works

  1. Pay at least the minimum and only the purchase rate applies to the rest.
  2. Pay less than the minimum and the unpaid part of the minimum carries late interest from the due date. Late interest is 0.30 points above the purchase rate.
  3. 15% KKDF and 15% BSMV are added to both.
