Assume that you are interested in understanding how much must be saved regularly over a period of time in order that at the ending of the period you have a particular amount. To answer such question here we manipulate the equation as
FVAn = A[((1 + k)n - 1)/k]
That demonstrates the relationship in between FVAn , A, K and
A = [k/((1 + k)n - 1)]FVAn ............................Eq(11)
Equation 11 assists in answering this question. The periodic deposit is easily A and is acquired by dividing FVAn by FVIFAk,n. In Eq 11[k/((1 + k)n - 1)] is the inverse of FVIFAk,n and is termed as the sinking fund factor.
