npv: npv

Description

Compute NPV

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
)

Arguments

init.cost

Initial investment cost

C

Periodic cash flow

cf.freq

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

TV

Terminal Value

T2M

Time to Maturity in years

disc.factors

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

BreakEven

TRUE when using a flat discount rate assumption.

BE.yield

Set the flat IR rate when BeakEven = TRUE.

Value

List of NPV and NPV Data frame
