In a word, outrageous.

The principal amount times the interest rate is equal to the amount of interest charged. So divide the interest amount by the principal amount to get the rate.

or 17% per month. That's over 200% per year, or ten times what it ought to be. Of course, if you typed one too few zeros on the balance amount, it would come out to a much more reasonable 1.7% per month.
