Asosi bahodihii samaranokii loiharo tahlili qiyosii hajmi sarmoyaguzorihoi peshnihodshavanda tashkil medihad.
Vobasta ba davrahoi gunoguni amaligardonii loiha, buzurgihoi muqoisashavanda metavonand harkhela boshand. Az in sabab masalai muhimi muayyankunii samaranokii loiha niz chun muayyankunii samaranokii tekhnika va tekhnologiyai nav – masalai muqoisai (tanosubi) daromadu kharojot ba hisob meravad. Sababi hisobkunii muqoisavi dar chunin holat asosan bequrbshavii pul, dinamikai manfii sarmoyaguzoriho, pastshavii istehsoloti sanoati, hududhoi gunoguni oyandabini, tagyirot dar nizomi andozsitoni va gayra meboshand.
Umuman usulhoi bahodihiii samaranokii loiharo ba du guruh judo namudan mumkin ast:
- Usulhoi bo bahodihii muqoisavi asosyofta;
- Usulhoi bahisobgiri.
Usulhoi bahodihii samaranokii loiha, ki tavassuti bahisobgiri surat megirand, davrai khudkharojotbarori, koeffitsienti samaranokii sarmoyaguzori va koeffitsienti pardokhti qarzro nishon medihand.
Usulhoi bahodihii loiha, ki tavassuti bahodihii muqoisvi surat megirand, afzaltar hisobida meshavand, chunki onho namudhoi gunoguni bequrbshavi, tagyiryobii meyori foizi va meyori
daromadnokiro ba hisob megirand. Ba in guruhi nishondihandaho dokhil meshavand: indeksi daromadnoki daromadi sofi diskonti va meyori dokhilii daromadnoki.
Usuli mamultarini hisobkunii samaranokii sarmoyaguzori – usuli khudkharidkunii mablagguzoriho ba hisob meravad. Ammo norasoii in usul dar on ast, ki vay arzishi pulro bo hisobgirii daromad dar davrahoi oyanda ba nazar nagirifta, prinsiphoi muqoisaviro etirof namekunad.
Azbaski dar iqtisodiyoti kishvari mo imruz bequrbshavii pul, kohishyobii meyorhoi foizi va meyorhoi pasti andukhti dokhilii korkhonaho mushohida megardad, tanho istifodabarii usuli khudkharidkunii sarmoyaguzoriho kofi nest. Az in sabab istifodabarii digar usulhoi bahodihii loihaho niz tavsiya doda meshavand.
