A fine is based on the offense in which you are convicted. The amount is determined by Georgia State Law. This could also take into account court costs.
The restitution would be money that you owe to a person or business. This could be money that you owe for a Court Appointed Attorney. It could also be to pay back the victim for the financial damage that you caused.
The fees are a supervisory fee that the courts charge for allowing you to go on probation. This is a monthly fee whether you see your Probation Officer or not.
