# Refinancing an Auto Loan: When It Saves Money and When It Costs You
Auto refinancing lets you replace your existing car loan with a new one, typically from a different lender. You'll want to refinance if interest rates have dropped since you took out your original loan or if your credit score has improved.
The main benefit is lower monthly payments. If you refinanced a $25,000 loan from 8% to 5% interest, you'd save hundreds of dollars over the loan term. Some borrowers refinance to shorten their loan period, paying off the car faster while keeping payments manageable.
But refinancing carries real costs. Most lenders charge origination fees between 1% and 5% of the new loan amount. On a $20,000 loan, that's $200 to $1,000 out of pocket. You'll also face hard credit inquiries that temporarily ding your credit score by a few points.
The math only works if your savings exceed the fees and closing costs. Use a refinance calculator to compare your current loan terms against new offers. Get quotes from credit unions, banks, and online lenders like SoFi, LendingClub, and Upgrade. Credit unions often offer competitive rates to members.
Timing matters. Refinancing within the first year or two of your original loan yields the biggest savings because most interest gets paid early in the loan term. Refinancing in year five delivers minimal benefit.
Watch your loan term carefully. Extending a five-year loan to seven years cuts monthly payments but increases total interest paid. If you need lower payments, extension might be necessary, but avoid stretching the term unnecessarily.
You cannot refinance a car you don't own outright. If you still owe more than the car's current value (underwater), few lenders will refinance. Wait until
