What does it mean to refinance a personal loan?

How refinancing works step by step: You apply for a new personal loan, usually from a different lender. If approved, the new lender pays off your old loan directly (or sends you funds to pay it off). You then make payments on the new loan under the new terms. Your original loan account is closed and marked 'paid in full.'

Good reasons to refinance: Your credit score improved by 50+ points since you took the original loan - you may qualify for a materially lower rate now. Interest rates in the market have fallen since your loan originated. You want to reduce your monthly payment by extending the term (though this increases total interest). You want to pay off the loan faster by shortening the term if the new rate is low enough.

Not-so-good reasons: Refinancing to extend the term to reduce a payment you can currently afford just to have more monthly cash - you pay more total interest. Refinancing repeatedly without a clear rate improvement, generating multiple origination fees.

Costs to consider: Some lenders charge a prepayment penalty on the old loan for paying it off early - check your existing loan agreement. The new loan may have its own origination fee (typically 1%-8%). Run the math: if the new origination fee plus prepayment penalty exceeds the interest savings from the lower rate over the remaining term, refinancing costs more than keeping the original loan.

Credit impact of refinancing: Applying for the new loan generates a hard inquiry (small, temporary score dip). The old loan is closed (can lower average account age). The new loan is opened. Net effect is usually neutral to mildly negative short term, positive long term if you pay on time.
