Each State has different rules for applying for marriage licenses including the cost. You usually apply for marriage licenses from the County Clerk in the County where you live and sometimes you can apply for a license from the County were the ceremony will be held. The cost can range from $30 to $70 depending on the State. Since you didn't mention where you'll be getting your license, you can use the following link http://publicrecords.onlinesearches.com/Marriage-Records.htm to access all of the counties in the U.S. You can choose your specific state and then scroll to your specific county.
