Investment appraisal can be used to clearly determine whether an investment is realizing
profits that were originally targeted.
u NPV
n : natural number up to 254
u NFV
u IRR
In this formula, NPV = 0, and the value of IRR is equivalent to i × 100. It should be noted,
however, that minute fractional values tend to accumulate during the subsequent calculations
performed automatically by the calculator, so NPV never actually reaches exactly zero. IRR
becomes more accurate the closer that NPV approaches to zero.
u PBP
n : smallest positive integer that satisfies the conditions NPV n < 0, NPV n +1 > 0, or 0
