is the annual effective interest rate, which is the "true" rate of interest over a year. Thus if the annual interest rate is 12% then i = 0.12 {\displaystyle \,i=0.12} . i ( m ) {\displaystyle \,i^{(m)}} (pronounced "i upper m") is the nominal interest rate convertible m {\displaystyle m} times a year, and is numerically equal to m ...
In actuarial mathematics, the accumulation function a(t) is a function of time t expressing the ratio of the value at time t (future value) and the initial investment (present value). [1] [2] It is used in interest theory. Thus a(0) = 1 and the value at time t is given by: = ().

The force of interest is less than the annual effective interest rate, but more than the annual effective discount rate. It is the reciprocal of the e -folding time. A way of modeling the force of inflation is with Stoodley's formula: δ t = p + s 1 + r s e s t {\displaystyle \delta _{t}=p+{s \over {1+rse^{st}}}} where p , r and s are estimated.
