For example, if a client pays back the loan amount before the due date, Mambu will display the exact interest amount that the client owes at that moment. Also, when a repayment is late, interest will keep accumulating each day. The only calculation method in which interest is not accrued in Mambu is Fixed Flat.

If the period from when the loan is disbursed to the very first repayment date is either longer or shorter than the usual payment cycle (e.g., a month), an adjustment is made to that first payment. Changing installment due dates: If you alter the due dates of your payments later on during the loan te ...
