Frequently Asked Questions

When should I refinance my car loan?

Refinance when you can get at least 1-2% lower interest rate, need to adjust monthly payments, or your credit score has improved significantly. Best timing is usually 6-12 months after your original loan when you've established payment history.

How much can I save by refinancing?

Savings depend on your rate reduction and remaining loan balance. A 2% rate reduction on a $20,000 balance can save $1,500-3,000 over the loan term. Use our calculator to see your specific savings potential.

What fees should I expect?

Typical refinancing fees range from $200-600, including origination fees, title transfer, and registration. Many lenders offer no-fee refinancing, but may have slightly higher rates. Always compare the total cost, not just the rate.

Can I refinance an upside-down car loan?

Yes, but it's challenging. You'll need to refinance the full amount you owe, even if it's more than the car's value. Some lenders specialize in upside-down refinancing, but expect higher rates and stricter requirements.

How long does the refinancing process take?

Refinancing typically takes 1-2 weeks from application to completion. Online lenders may process applications faster, while traditional banks might take longer. Gather all documents beforehand to speed up the process.

Will refinancing hurt my credit score?

The initial credit check may temporarily lower your score by 5-10 points. However, shopping multiple lenders within 14-45 days counts as a single inquiry. Long-term, consistent payments on your new loan will improve your credit.
