Bala amaphesenti ngokushesha — thola X% yenombolo, ukuthi X imaliphi amaphesenti ka-Y, noma ukuguquka kwamaphesenti phakathi kwamavelu amabili. Isibali samahhala samaphesenti ku-inthanethi.

Isibali Samaphesenti
Isibali zethu samaphesenti sinikeza izindlela ezintathu ezibalulekile zokubalwa esiswini esikhululekile esisodwa. Noma ngabe udinga ukuthola iphesenti lenani, ukuqiniseka ukuthi iphesenti lenani elilodwa eliselinye, noma ukukhokha inguquko yephesenti phakathi kwamanani amabili, uthole imiphumela ngokushesha ngaphandle kokuqopha.
Amafomula
Ukuthola i-X% yenani: phindaphinda i-Y nge-X bese uhlukanisa ngo-100. Ngokwesibonelo, 25% ka-80 = 80 × 25 / 100 = 20.
Iphesenti i-X liye-Y: hlukanisa i-X nge-Y bese uphindaphinda ngo-100. Uma uthola amaphoyinti angama-42 kwangama-50, lokho ku-42 / 50 × 100 = 84%.
Inguquko yephesenti: ((Okusha − Okudala) / |Okudala|) × 100. Uma isitoko saya ku-€50 saya ku-€65: ((65−50)/50) × 100 = 30% yokunyuka.
Umehluko Obalulekile
Lena mthombo ovamile wokudideka. Iphesenti linkomba enobudlelwano, kanti amanqamu aphesenti ayiqiniso. Uma izinga lenzalo liya ku-5% liye ku-7%, linyuka nganqamu ezimbili zamaphesenti, kodwa ngo-40% ngokwezibalo ezinobudlelwano (2/5 × 100 = 40%).
Izihloko zezikhangiso ngokuvamile zixuba lezi, ngakho ukuqonda umehluko kukusiza ukuhumusha ulwazi lwezimali ngendlela efanele. Sebenzisa i-isibali semorgeji zethu ukuze ubone umthelela wangempela wemehluko wamazinga enzalo.
Izimali Zobuqu
Imehluko ka-1% esizingeni semorgeji yakho esikweletini se-€200,000 iminyaka engama-25 ikhokha cishe i-€27,000 eyengeziwe entenyweni ephelele. Uma i-portfolio yakho ibuya ngo-7% ngomnyaka ngokuqhathaniswa nango-5%, ku-€50,000 eyofoniselwa iminyaka eli-20 loyo mehluko ulingana ngaphezu kwe-€60,000.
Ku-2.5% yokwenyuka kwezindleko ngomnyaka, i-€100 namuhla iyoba namandla okuthenga akuphela ku-€78 eminyakeni eli-10. Ukuphakanyiswa kuka-3% kumholo we-€2,000/inyanga kwengeza i-€720/unyaka.
Amathiphu Wezibalo Zengqondo
10%
Hambisa iphoyinti ledesimali endaweni eyodwa uye kwesokunxele. 10% kwangu-250 = 25.
5%
Thola u-10% futhi uwuhlukanise ngohhafu. 5% kwangu-250 = 12.5.
25%
Hlukanisa ngo-4. 25% ka-250 = 62.5.
50%
Hlukanisa ngo-2. 50% kwangu-250 = 125.
1%
Hambisa idesimali izindawo ezimbili kwesokunxele. 1% kwangu-250 = 2.5.
Noma iyiphi %
Hlanganisa okungenhla: 15% = 10% + 5%, 30% = 3 × 10%.
Ukuthola X% ka-Y, phinda Y nge-X usehlukanise nge-100. Ngokwesibonelo, 15% ka-200 = 200 × 15 / 100 = 30. Isibali zethu sikwenza lokhu ngokushesha — faka nje amaphesenti nenombolo.
Ukuthola ukuthi X imaliphi amaphesenti ka-Y, hlukanisa X nge-Y uphinde nge-100. Ngokwesibonelo, 30 imaliphi amaphesenti ka-200? 30 ÷ 200 × 100 = 15%. Sebenzisa ithebhu lethu elithi 'X imaliphi amaphesenti ka-Y?' ukuthola imiphumela ngokushesha.
Ukuguquka kwamaphesenti = ((Okusha - Okudala) / |Okudala|) × 100. Ngokwesibonelo, ukuguquka kusukela ku-100 kuya ku-150 = ((150-100)/100) × 100 = ukukhula kwa-50%. Ukuguquka kusukela ku-200 kuya ku-150 = ((150-200)/200) × 100 = ukwehla kwa-25%.
Amaphesenti uyindlela yokulingana, kuyilapho amapoint amaphesenti yindlela yokwenziwa. Uma izinga lentengo liya ku-5% likhula liye ku-7%, likhule ngamapoint amabili amaphesenti kodwa ngama-40% (2/5 × 100). Lo mehluko ubalulekile ezimweni zemali.
Amahlaya asheshayo engqondweni: 10% = susa isipho esinye kwesokunxele. 5% = inxenye yama-10%. 25% = hlukanisa nge-4. 50% = hlukanisa nge-2. 1% = susa izipho ezimbili kwesokunxele. Hlanganisa lawa ngawo nawaphi amaphesenti: 15% = 10% + 5%, 30% = 3 × 10%.
