Chiwerengero cha Chiwerengero cha Chidwi

Mukabwereka ndalama kubanki, mumalipira chiwongola dzanja. Chiwongoladzanja ndi chindapusa chobwereketsa ndalamazo, ndimaperesenti omwe amalipiritsa pamtengo pachaka chimodzi - kawirikawiri.

\( S = P \left(1 + \dfrac{j}{m}\right)^{mt} \ \ \) kumene:

\( S \)	mtengo pambuyo pake \( t \) nthawi
\( P \)	ndalama zake zonse
\( t \)	ndi zaka zomwe ndalamazo zimakongola
\( j \)	ndi chiwongola dzanja chapachaka (chosawonetsa kuphatikiza)
\( m \)	ndi kangapo chidwi chimaphatikizidwa pachaka
