Summary: 1 Interest Theory
A(t) is the amount function. a(t) is the accumulation function. a(t) = A(t)
A(0)

vt = 1
a(t)
, t 0, is called the discount function discount function.

Under compound interest vt = (1+i)-t
. i is the annual effective rate of interest. 1+i
is the one year interest factor. = 1 - d is the one year discount factor. d is the
annual rate of discount.
i =
