The answer is: complete sentence.
This is an independent sentence, which means it is a group of words that that has a complete thought. It has a subject and a verb and it can stand on its own. Subject: The balance. Verb: includes. Complement: both the fees for service and the shipping charges. A phrase that has a subject and a verb but doesn't have a complete thought is a dependent clause, and it can't stand on its own.
