Investment appraisal can be used to clearly determine whether an investment is realizing profits that were originally targeted. S\NPV NPV = CF0 + CF1 (1+ i) + CF2 (1+ i)2 + CF3 (1+ i)3 + ... + CFn (1+ i)n n: natural number up to 254 I% i = 100 S\NFV NFV = NPV s(1 + i )n S\IRR 0 = CF0 + CF1 + (1 + i ) CF2 + (1 + i )2 CF3 + (1 + i )3 ... + CFn (1 + i )n 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. S\PBP {0 CF0 > 0) PBP = n - NPVn ... (Other than those above) NPVn+1 - NPVn
