Simple Interest Charged (Engineering Economics)
Description
Computes the total interest paid at the end of n periods using simple interest
Usage
SimpIntCharg(P, n, i)
Arguments
P |
numeric vector that contains the present value(s) |
n |
numeric vector that contains the period value(s) |
i |
numeric vector that contains the interest rate(s) as whole number or decimal |
Details
Simple Interest Charged is expressed as
I = Pni
- P
the "principal amount (lent or borrowed)"
- I
the "simple interest"
- i
the "interest rate per interest period"
- n
