Effective interest rate for t periods, i t = (1 + i) t - 1 or as one equation i t = (1 + (r / m)) mt - 1. The rate per compounding period P = R / m, in percent.
Under the effective interest rate method the amount of interest expense in a given year will correlate with the amount of the bond's book value. This means that when a bond's book value decreases, the amount of interest expense will decrease.
