u IRR
IRR is calculated using Newton's Method.

0 (1+ i )
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.
