Interest rate given Future value, Number of periods, and Present value (Engineering Economics)
Description
Compute i given F, n, and P
Usage
igivenPFn(P, F, n)
Arguments
P |
numeric vector that contains the present value(s) |
F |
numeric vector that contains the future value(s) |
n |
numeric vector that contains the period value(s) |
Details
i is expressed as
i = \sqrt[n]{\frac{F}{P}} - 1
- i
the "effective interest rate per interest period"
- F
the "future equivalent"
- P
the "present equivalent"
- n
the "number of interest periods"
Value
i numeric vector that contains the effective interest rate as a percent rounded to 2 decimal places
