Time Value of Money

Description

Solves for the present value, future value, time, or the interest rate for the accumulation of money earning compound interest. It can also plot the time value for each period.

Usage

TVM(pv=NA,fv=NA,n=NA,i=NA,ic=1,plot=FALSE)

Arguments

`pv`	present value
`fv`	future value
`n`	number of periods
`i`	nominal interest rate convertible ic times per period
`ic`	interest conversion frequency per period
`plot`	tells whether or not to produce a plot of the time value at each period

Details

j=(1+\frac{i}{ic})^{ic}-1

fv=pv*(1+j)^n

Value

Returns a matrix of the input variables and calculated unknown variables.

Note

Exactly one of pv, fv, n, or i must be NA (unknown).

Examples

TVM(pv=10,fv=20,i=.05,ic=2,plot=TRUE)

TVM(pv=50,n=5,i=.04,plot=TRUE)
