1. Divide the amount of the substance at one point in time by the amount remaining after a period of time. 1  The formula for calculating half life is as follows: t1/2 = t * ln(2)/ln(N0/Nt). 2  In this formula, t = time gone by, N 0 = amount of substance at the beginning, and N t = amount of substance after a period of time.
