It costs about $400 to $639 to replace an alternator as of 2014, depending on the make and model of the car. This amount includes the cost of parts, which is about $279 to $485 excluding taxes and fees, and the cost of labor, which is about $121 to $154.

It is cheaper to buy a rebuilt or remanufactured alternator than a new one. Rebuilt and remanufactured alternators are used alternators that have been restored to functionality by replacing parts that are worn out or prone to failure. It is also typically cheaper to have an alternator repaired than to have it replaced, especially if a repair kit for that particular alternator is available. Repair kits cost about $12 to $30.
