Perjury is considered a serious offense as it can be used to usurp the power of the courts, resulting in miscarriages of justice. In the United States, for example, the general perjury statute under Federal law classifies perjury as a felony and provides for a prison sentence of up to five years.
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.
How to Calculate APR. Assuming the principal amount is $100 at the beginning of a period, the quoted interest rate is 10 percent, and that interest is compounded semiannually, or twice a year. How to calculate APR thus involves the following computations.Covert the annual interest rate of 10 percent to a semiannual rate of five percent (10 percent/2 = 5 percent). Multiply the $100 principal by the periodic semiannual rate of 5%, and get $5 in interest.or example, how to calculate APR semiannually for the quoted interest rate of 10 percent requires the conversion of the annual rate to a periodic semiannual interest rate of five percent.
