Kushandisa IRR inzira yekuongorora kushandiswa kwezvakatarisira (kana kuti chaiyo) inodzoka inopesana gore negore kana nguva kusvika panguva.
Kunze kwechikwereti zviridzwa zvinounza kuwedzera kwekudzoka pamusoro pehupenyu hwavo, kusiyana kwakadaro ndiko kuripo. I IRR methodology chinhu chinogadzirisa kuwana imwe chete, inowanikwa mumakero ekudzoka kubva mumamiriro ezvinhu akadaro.
Kana icho chaicho chiri kutora mubhadharo (iyo ndiyo inoretic mari yekambani kune iyo kambani kana muzvinamari ari mubvunzo) yakaderera pane IRR, purojekiti kana kushandiswa kunofanira kuitwa. Icho chisarudzo chekuita chisarudzo chechigunwe chinoshandiswa apo IRR inoshandiswa shanduko yekuongorora kuongorora mapurojekiti kana kuisa mari.
Simple Simple Example
Iwe unokwereta $ 1,000 kune mumwe munhu. Pari pemitemo yemukwereti, iwe uchawana mubhadharo wekubhadhara we 11% ($ 110) pakupera kwegore rokutanga, uye 20% yebhadharo yemari ($ 200) pakupera kwegore rechipiri, panguva iyo iwewo gamuchira yako $ 1 000 guru guru.
IRR yako, kana Internal Rate Yokudzoka, pachikwereti ichi, yaizova 15.1825%.
Heano huno uchapupu hwomugumisiro iwoyo:
Nhamba yezvino ye $ 110 iri $ 95.50, iyo inopiwa kuderedzwa kwehuwandu hwe15.1825%.
Ndiko, $ 110 / 1.151825 = $ 95.50
Panguva ino, kukosha kwemazuva ano kwe $ 1,200 kune $ 904.50, iyo inopiwa kuderedzwa kwema 15.1825%.
Kunyanya, $ 1,200 / ((1.151825) ^ 2) = $ 904.50
Uye, $ 95.50 + $ 904.50 = $ 1,000.00
Computing IRR
Iko HP12c Financial Calculator inyanzvi yekare, ichiri mukushandiswa kwakapararira, kune kuverenga kwe IRR, kana Internal Rate yekudzoka.
Uyezve, mapurogiramu akawanda epasheet, akadai seMicrosoft Excel, anopa nzvimbo yacho kuverenga.
Zvishandiswa zveRR
Mutengo wekudzoka mukati, sezvakambotaurwa kare, chimbo chinokudzwa panguva dzakasiyana-siyana dzemari. Mukujekesa kweprojekiti, somuenzaniso, inowanzoshandiswa kusarudza kana basa rakapiwa rinofanira kuitwa. Zvisinei, sezvinotsanangurwa mune chikamu chinotevera, kushandiswa kweRR mumasikirwo akadaro anotarisa kune kukanganisa kwekushandiswa kune zviitiko zvinotarisirwa, zvinogona kana kuti zvisingasvike pakubudirira.
Mune fashoni inotarisa kumashure, IRR inoshandiswa kuongororai maitiro chaiwo emitemo. Mari yekutsvaga mari, kunyanya hedge funds, inowanzoitora iyo sechirongwa chikuru chezvinyorwa zvadzo.
Muzvizhinji, IRR inowanzoshandiswa-inoshandiswa kuti iongorore mari chaiyo kana kuti inogona kushandiswa iyo maitirwo akasiyana-siyana kana anotarisirwa kusiyana nekufamba kwenguva. Mundima iri nyore nhamba iri pamusoro apa, uyo anokwanisa kukweretesa ari kugamuchira chikamu chepakati pekudzoka kwegore negore kubva 15.18% pamari yake uye inofanira kufananidza izvi nemamwe mikana yekutsvaga kutonga zvaanoda.
Kukanganisa kweRR Analysis
Kudzoka kana kurongerwa kunofanirwa kunogona kusingaiti sezvinotarisirwa.
Chirongwa kana kushandiswa kwechirongwa neAIRR inotarisirwa pasi inogona kunge yakanakisisa kana iyo IRR yakadzika inogona kuwanikwa pane imwe huru yakakura.
Semuenzaniso, mukana wekuwana 30% pane $ 100,000 inotengeswa inounza mhedziso yakakwana kupfuura 40% pa $ 1 000.
Chirongwa kana kushandiswa kwechirongwa neAIRR inotarisirwa pasi inogona kuve yakakosha kana iyo IRR iri pasi inogona kuwanikwa kwenguva yakareba. Somuenzaniso, kuwana mari yakawanda 30% pamakore mana, iyo inowedzera katatu kubhadhara kwako, zviri pachena kuti ndiyo imwe nzira iri nani kupfuura kuwana 40% kwegore rimwechete uye kuva netariro yakawanda yekutorazvezve shure kweizvozvo.
Iyo yose IRR yemugovera wekutsvaga kwekutsvaga haisi yevhareji ye IRRs pane imwe purojekiti, kuchengeteka kana kutengesa mairi. Pane kudaro, iyo IRR yakawanda yenzvimbo yepamusoro uye yepamusoro yekudzoka kwekutanga kwemari yakawanda inopfuura yakawanda IRR yenzvimbo yepamusoro iyo yakawanda inowanikwa gare gare, kunyange kana iyo yekupedzisira iine zvikwereti zvakawanda pane nguva.
Nokudaro, vatungamiri vehutano vari voga vanoedza kutsvaga IRR yepamusoro pane imwe nzvimbo yekutsvaga kwekutsvaga kuburikidza nekuwana mari yekukunda mari yekukurumidza nekuramba uchirasikirwa nemari.
