RTL (version 1.3.7)

npv: NPV

Description

Computes NPV with discount factor interpolation. This function is used for teaching NPV and NPV at Risk and needs to be customized.

Usage

npv(
  init.cost = -375,
  C = 50,
  cf.freq = 0.25,
  TV = 250,
  T2M = 2,
  disc.factors = us.df,
  BreakEven = FALSE,
  BE.yield = 0.01
)

Value

List of NPV and NPV Data frame. list

Arguments

init.cost

Initial investment cost. numeric

C

Periodic cash flow. numeric

cf.freq

Cash flow frequency in year fraction e.g. quarterly = 0.25. numeric

TV

Terminal Value. numeric

T2M

Time to Maturity in years. numeric

disc.factors

Data frame of discount factors using ir.df.us() function. numeric

BreakEven

TRUE when using a flat discount rate assumption. logical

BE.yield

Set the flat IR rate when BreakEven = TRUE. logical
