Yes you can pay-off your car loan before the tenure is up by pre-paying your loan amount. But there may be certain rules regarding the pre-payment that your bank may have. Also you may have to pay a small penalty, normally, a percentage of the loan amount that remains outstanding. Some banks however do not penalize you if you decide to pre-pay. Take this aspect into consideration when you choose a bank to take loans from because if later on, you can get a loan at a lower rate of interest, this penalty could compensate whatever you could save through the interest rate differential.
