IRR
IRR
is calculated using Newton’s Method.
In this formula,
NPV
= 0, and the value of
IRR
is equivalent to
i
s
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.
