I have found the following formula to calculte the apr. I would like to know why there is a 2 in the equation? i = 2 x n x I /( P(N + 1)) in which i is the APR n is the number of payment periods in one year I is the total financing charges (mostly interest) P is the principal (the amount borrowed), and N is the number of scheduled payments
