Clases de Interés Simple

Imaginate que prestás plata a un amigo: el interés simple significa que solo ganás dinero extra sobre la cantidad original que prestaste. Tu capital inicial nunca cambia, y los intereses no se suman para generar más intereses.

La fórmula básica es súper directa: I = P × i × T, donde P es tu capital, i es la tasa de interés, y T es el tiempo. Es como una receta matemática que siempre funciona igual.

El monto o valor futuro te dice cuánta plata vas a tener al final. Se calcula con S = P1+i×T1 + i × T, y básicamente suma tu dinero inicial más los intereses ganados.

Ejemplo práctico: Si invertís $65.000 al 32% anual por 90 días, terminás con $70.200. ¡Son $5.200 de ganancia por dejar tu plata trabajar!

Valor Presente y Cálculos Avanzados

Continuando el ejemplo anterior: si tenés $80.000 por 4 meses al 30%, tu monto final será $88.000. La clave está en convertir siempre los meses a días 4meses=120dıˊas4 meses = 120 días para usar correctamente las fórmulas.

El valor presente funciona al revés: te dice cuánto vale hoy un dinero que vas a recibir en el futuro. Su fórmula es Vp = S/1+i×T1 + i × T, y es súper útil para evaluar ofertas y descuentos.

Un documento que vale $90.000 al vencimiento, con interés del 28%, tiene un valor presente de $86.042 si lo cobrás 60 días antes. Esto significa que estás "perdiendo" $3.958 por cobrar anticipado.

Consejo clave: Siempre verificá si la tasa es comercial (360 días) o racional (365 días), porque esto cambia completamente tus cálculos y resultados finales.

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.

Samantha KlichAndroid user

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.
