month, what is the APR?
The APR is the annual percentage rate
therefore the APR is 1.5x12=18%
If the monthly interest is 1.5%, then the APR is
100 [ (1.015)¹² - 1 ] = 19.56 %
You might think that it would be (12 x 1.5) = 18%, but its not.
The interest is compounded. That means interest is added this month,
and then it becomes part of the amount on which interest is charged
So youre charged interest on interest, and it adds up.
