I want to go for loan prepayment. What options for loan prepayment are available?

I want to pay for the loan earlier than the due date.

If you want to pay the whole loan amount before the loan tenure, you can save on the interest.
You can either do full prepayment or partial prepayment.
Partial prepayment helps in reducing the EMI and the principal amount, so you can choose this option.
Make sure the lender provides these services, and then decide on a method.
