Casio FC-100V, FC-200V NPV = CF0 +, CF2, CF3, CFn, NFV = NPV ⋅ (1 + i )n, NPV, IRR, PBP

•Though Iis a financial calculation variable, it is also used by arithmetic and function operations in the COMP Mode.

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.

uPBP

	{	0 ..................................		(CF0 >0)
PBP =		n –	NPVn	... (Other than
			NPVn+1 – NPVn	those above)

n

NPVn = Σ CFk k = 0 (1 + i)k

n: Smallest positive integer that satisfies the conditions NPVn <0, NPVn+1 >0, or 0.
