Be careful with that thinking. Many people get into trouble because they think making extra payments allows them to skip. This is rarely the case. It changes the payments on the back end, not the front end. Most institutions will charge late fees and report missed payments if you just skip a payment, even if you have been paying extra. The banks that don't do that are often just applying extra payments the same as a regular payment, just sooner. (Meaning they aren't applying it all to principal). You still finish sooner, but end up paying a lot more. Some make you specify principal only on the extra payment. Caveat Emptor.
