Refinancing is the process of replacing an existing loan with a new loan, usually to get better terms like lower interest rates, lower EMI, or improved tenure.
Refinancing allows borrowers to modify their loan conditions by taking a new loan—either from the same lender or a different one—to pay off the existing loan.
It is commonly used for home loans, personal loans, and business loans. In India, such lending practices follow guidelines of the Reserve Bank of India.
