Convert between compound-interest quantities

Provides consistent conversions between: - effective interest rate i - effective discount rate d - force of interest delta

Usage

interest_convert(i = NULL, d = NULL, delta = NULL, m = NULL)

Arguments

i

Effective interest rate.

d

Effective discount rate.

delta

Force of interest.

m

Optional compounding frequency for the nominal rate convertible m-thly.

Value

A list with elements i, d, delta and, if m is supplied, im (the nominal rate convertible m-thly).

Details

Exactly one of i, d, or delta must be provided.

Examples

interest_convert(i = 0.05)
