What does it mean to refinance an auto loan?

Refinancing means replacing your current car loan with a new loan, often with a lower interest rate or different term, so you can save money or adjust payments.

When is it a good idea to refinance my auto loan?

It makes sense to refinance if your credit has improved, interest rates have dropped, or you need lower monthly payments. Always compare total costs before deciding.

Will refinancing hurt my credit score?

Applying for a new loan may cause a small, temporary dip in your credit score, but responsible payments on the new loan can help your credit over time.

Do I need to enter refinance fees?

No, fees are optional. If you enter them, the calculator will show your break-even point. If you leave fees at $0, it will show savings start immediately.

Can I compare different loan terms?

Yes, you can adjust the new loan term (months) to see how a shorter or longer refinance term affects your monthly payments and total interest.

How do I download the amortization schedule?

After calculating, use the “Download Full Schedule” option to export a detailed payment breakdown for the entire loan term in Excel or PDF format.
