Indlela yokubala izinga lokukhula?
Igama elithi 'izinga lokukhula' lichaza izinga lokuguquka kwenani le-metric ethile esikhathini esithile, elivezwe njengephesenti.  Izibonelo ezivamile zezimo lapho isilinganiso sokukhula sivame ukusetshenziswa yilezi ezilandelayo:  Inkampani Yokuthengisa Izibalo Zabantu Umkhiqizo Womhlaba Wonke (GDP) Izinga lokwehla kwamandla emali Ngaphansi kwesimo esithile sokumodela kwezezimali, izinga lokukhula livame kakhulu ngekota noma ngonyaka (okungukuthi unyaka nonyaka).  Izibikezelo ezingasekelwa kakhulu zingenziwa mayelana nomzila wesikhathi esizayo we-metric okukhulunywa ngayo ngokunquma ukukhula kwayo okungokomlando, okungasebenza njengephuzu eliwusizo lokubhekisela ngezinhloso zokubikezela.  Kodwa-ke, usizo lwe-metric lusalokhu luboshelwe ezingeni lapho abashayeli abasemqoka bekhonjwa futhi bacwaningwa ngokujulile.  Ngokwalo, ukubala ukukhula komlando akwanele, ngoba yini empeleni eyabangela ukukhula kwesikhathi esidlule futhi yiziphi izici ezisezingeni ezizokwazi ukunquma ukukhula kwesikhathi esizayo.   Ifomula elandelayo ingasetshenziselwa ukubala izinga lokukhula phakathi kwezikhathi ezimbili.  Izinga Lokukhula (%) = (Inani Lokugcina ÷ Inani Lokuqala) <unk> 1 Isibonelo, uma imali engenayo yenkampani yayingu-$100 million ngo-2020 futhi yakhula yaya ku-$120 million ngo-2021, izinga layo lokukhula lonyaka nonyaka (YoY) lingu-20%.  Izinga Lokukhula = ($120 million ÷ $100 million) <unk> 1 = 0.20, noma u-20%
