The accumulation function a(t) is a function defined in terms of time t expressing the ratio of the value at time t (future value) and the initial investment (present value) it is used in interest theory thus a(0)=1 and the value at time t is given by: a ( t ) = a ( 0 ) ⋅ a ( t ) {\displaystyle a(t)=a(0)\cdot a(t)} {\displaystyle a(t)=a(0)\ cdot a.
