ImmoAnnuRechner

Der ImmoAnnuRechner in Aktion.

Um die tatsächlichen Kosten einer Immobilienfinanzierung per Annuitätendarlehen berechnen zu können, habe ich einen extrem einfach gehaltenen Rechner implementiert, den Ihr per Browser aufrufen könnt:

ImmoAnnuRechner – Website

Der Rechner funktioniert folgendermaßen:

Veränderbare Eingaben sind:

• Kaufpreis.
• Diverse Nebenkosten (%).
• Eigenkapital.

=> Damit wird das benötigte Fremdkapital berechnet.

• Zinssatz (%).
• Anfangstilgung (%).

=> Dadurch werden dann die restlichen Ergebnisse berechnet, u.a.:

• Monatliche Rate.
• Laufzeit.
• Gesamtzinsen.

“Klickt” man sich aus einem Eingabefeld “heraus”, werden alle Werte automatisch erneut berechnet (also aktualisiert).

Die aktuellste Beschreibung und den kompletten Source Code findet Ihr unter:

Viel Erfolg beim Immobilienkauf
