Interés Simple: Lo Básico que Necesitas Saber

El interés simple es la ganancia o costo adicional que se calcula solo sobre el capital inicial. Es súper directo: no hay complicaciones con intereses que generan más intereses.

La fórmula mágica es: I = C × i × t. Donde I es el interés que ganas o pagas, C es el capital (la plata inicial), i es la tasa de interés (convertida a decimal), y t es el tiempo.

Miremos el ejemplo: el BBVA le presta S/8000 al señor Puicón al 4% mensual por 7 meses. El cálculo es: I = 8000 × 0.04 × 7 = S/2240. ¡Así de fácil!

Tip clave: Siempre convierte los porcentajes a decimales dividiendo entre 100. El 4% se convierte en 0.04.

También puedes despejar cualquier variable de la fórmula principal:

Para sacar el capital: C = I ÷ (i × t)
Para la tasa: i = I ÷ (C × t)
Para el tiempo: t = I ÷ (C × i)

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.
