If you have the means, paying off your car loan early is fairly straightforward. The best way to do so is to increase your monthly payment above what your required payment is. For example, if your monthly payment is $300 and you can afford to pay $500, then you'll be able to pay off your loan early. Other tips include making a large payment every year and not missing any payments. You may have to check with your lender if you can pay off early.
