Stosuje się standardowy wzór malejącego salda oparty na kwocie kredytu, stopie procentowej i okresie kredytowania. Odsetki naliczane są od salda pozostałego do spłaty, które maleje z każdą płatnością.

Tak — dłuższy okres obniża miesięczną ratę, ale zwiększa łączne odsetki zapłacone przez cały czas trwania kredytu. Krótszy okres oznacza wyższe raty, ale znacznie mniejsze łączne odsetki.
