Description

This functions returns the value at time n of a series of equally spaced payments of 1.

Usage

1
	accumulatedValue(i, n,m=0, k,type = "immediate")

Arguments

i

Effective interest rate expressed in decimal form. E.g. 0.03 means 3%.

n

Number of terms of payment.

m

Deferring period, whose default value is zero.

k

Frequency of payment.

type

The Payment type, either "advance" for the annuity due (default) or "arrears" for the annuity immediate. Alternatively, one can use "due" or "immediate" respectively (can be abbreviated).

Details

The accumulated value is the future value of the terms of an annuity. Its mathematical expression is s_{≤ft. {\overline {\, n \,}}\! \right| } = ≤ft( {1 + i} \right)^n a_{≤ft. {\overline {\, n \,}}\! \right| }

Value

A numeric value representing the calculated accumulated value.

Warning

The function is provided as is, without any guarantee regarding the accuracy of calculation. We disclaim any liability for eventual losses arising from direct or indirect use of this software.

Note

Accumulated value are derived from annuities by the following basic equation {s_{≤ft. {\overline {\, n \,}}\! \right| }} = {≤ft( {1 + i} \right)^n} = a_{≤ft. {\overline {\, n \,}}\! \right| }.
