Wie wird die Baudarlehen-EMI berechnet? ▼
Sie verwendet die übliche Restschuld-Formel auf Basis Ihres Darlehensbetrags, Zinssatzes und der Laufzeit. Zinsen werden auf die ausstehende Restschuld berechnet, die mit jeder Zahlung sinkt.
Senkt eine längere Laufzeit meine EMI? ▼
Ja — eine längere Laufzeit senkt die monatliche EMI, erhöht aber die gesamten Zinsen, die Sie über die Laufzeit des Darlehens zahlen. Eine kürzere Laufzeit bedeutet höhere EMIs, aber deutlich weniger Gesamtzinsen.
Was passiert, wenn ich eine Sondertilgung leiste? ▼
Eine Sondertilgung verringert Ihre ausstehende Restschuld, was die Gesamtzinsen senkt und Ihre Laufzeit verkürzen kann. Nutzen Sie den Hypotheken-Tilgungsrechner, um die Auswirkung zusätzlicher Zahlungen zu sehen.
