Alles über Rabatt, MwSt, Brutto/Netto und Zinsen
Grundbegriffe einfach erklärt
Rabatt kennst du bestimmt schon vom Shopping - das ist einfach ein Preisnachlass, den du auf Waren oder Dienstleistungen bekommst. Meistens wird er in Prozent angegeben, manchmal auch als fester Betrag.
Die Mehrwertsteuer zahlst du als Endverbraucher bei jedem Einkauf mit, ohne es oft zu merken. Aktuell liegt sie bei 19% und ist bereits in den meisten Preisen enthalten, die du im Laden siehst.
Bei Brutto und Netto gibt es eine coole Merkhilfe: "Netto = Ned so viel, Brutto = Brutal viel". Beim Gehalt ist Brutto der Gesamtbetrag vor allen Abzügen, Netto das, was wirklich auf dem Konto landet. Die Formel dazu: Bruttolohn - Steuern und Sozialversicherungsbeiträge = Nettolohn.
Zinsen sind der Preis, den du für geliehenes Geld zahlst - oder den du bekommst, wenn du Geld anlegst. Sie hängen vom Zinssatz, der Laufzeit und der Höhe des Betrags ab.
Tipp: Diese Begriffe begegnen dir täglich - vom Taschengeld bis zum Ferienjob!
Formeln und Beispiele
Rabatt berechnen ist total einfach: Du multiplizierst den Preis mit der Prozentzahl und teilst durch 100. Bei einem 700€-Sofa mit 20% Rabatt rechnest du: (700 × 20) ÷ 100 = 140€ Rabatt. Der neue Preis ist dann 700€ - 140€ = 560€.
Mehrwertsteuer kannst du in beide Richtungen rechnen. Um sie draufzuschlagen, addierst du sie zum Nettopreis (10,92€ + 2,07€ = 12,99€). Um sie abzuziehen, teilst du den Bruttopreis durch 1,19 - so kommst du vom Bruttopreis zurück zum Nettopreis.
Zinsen berechnest du mit der Formel Z = (K × p) ÷ 100. Dabei ist Z der Zinsertrag, K dein Anfangskapital und p die Zinszahl. Das Endkapital ist dann dein Anfangskapital plus die Zinsen.
Diese Formeln sind deine Werkzeuge für viele Alltagssituationen - vom Schnäppchen-Check bis zur ersten Geldanlage!
Merke dir: Mit diesen drei Formeln kannst du schon richtig viel im Alltag berechnen!
