Not sure where you are getting that 7 percent from. If you show me a link, I can explain to you why you may be misreading or misinterpreting. Here is the text of the GA statute:
O.C.G.A. 7-4-18 (2010)
7-4-18. Criminal penalty for excessive interest
(a) Any person, company, or corporation
who shall reserve, charge, or take for any loan or advance of money, or forbearance to enforce the collection of any sum of money, any rate of interest greater than 5 percent per month,
either directly or indirectly, by way of commission for advances, discount, exchange, or the purchase of salary or wages; by notarial or other fees; or by any contract, contrivance, or device whatsoever shall be guilty of a misdemeanor; provided, however, that regularly licensed pawnbrokers, as defined in Code Section 44-12-130, are limited in the amount of interest they may charge only by the limitations set forth in Code Section 44-12-131.
