What Is Loan Prepayment? You can clear off your personal loan fully or partly before the actual tenure of the loan ends. If you see a lump sum accumulating in your account, you can use it to prepay your loan. 

What Are The Benefits of Loan Prepayment?
    When you have taken a loan, it is quite tiring to pay an interest amount every year. So, it will be a good idea to prepay your loan Full prepayment of your current loan is considered positive and has a positive impact on your CIBIL™ score .  It will help you to become debt-free. A debt-free life is good, since it helps you to be stress-free, leaves you with more money in your account, helps you to get financial independence earlier, and mitigates the risk of financial crisis. 
What Is Personal  Part Prepayment
    Part prepayments also bring down the interest rates on loans.  Post making your prepayment, you can maintain the same loan tenure and reduce your EMIS or pay the same EMIs and shorten your loan duration.  But, part prepayments are effective only when you pay a lump sum.  Also, if you have prepayment charges, paying partly will have a negligible impact on your EMIs.  Most importantly, some banks do not allow part prepayments on personal loans, so find out the prepayment rules and conditions before you apply for a personal loan.
