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.
