Auto Loan Refinancing Basics
When refinancing makes sense
- Your credit score improved since you financed at the dealer.
- Market rates dropped or you qualified for a better APR.
- You want to lower monthly payments by extending the term.
- You want to pay less interest by shortening the term at a lower APR.
What lenders consider
- Credit & income stability and debt-to-income ratio.
- Vehicle value & age – many cap age/mileage; high mileage can limit approval.
- LTV (loan-to-value): large negative equity can restrict options.
Costs & gotchas
- Admin/registration fees – include them in the calculator’s fee field to see the impact.
- Prepayment penalties on your current loan may reduce savings.
- Term extension lowers payments but can increase total interest – check “Lifetime Savings.”
- Insurance – some lenders require full coverage; keep this in mind for overall budget.
Break-even check
- Compare old vs. new total interest plus any fees.
- If the new total is lower and payments fit your budget, refinancing likely makes sense.
Auto Loan Refinancing FAQs
Can I refinance with negative equity?
It’s possible, but options may be limited. Some lenders allow rolling negative equity into the new loan, which can raise your payment and total interest.
How soon after purchase can I refinance?
Many lenders let you refinance after 3–6 months of on-time payments. Some will consider earlier on a case-by-case basis.
Will refinancing hurt my credit?
A credit inquiry may cause a small, temporary dip. On-time payments on the new loan can help your score over time.
Are there fees to refinance?
Yes, some lenders charge administrative or registration fees. Add them in the calculator to see if savings still make sense.
Does refinancing always save money?
Not always. Extending the term can increase total interest even if the payment falls. Compare “Total Interest – Current” vs. “Refi.”
Can I shorten my term when refinancing?
Yes. If you can afford a higher payment at a lower APR, you’ll usually pay far less interest over the life of the loan.
Do I need a co-signer?
Only if your credit or income doesn’t qualify on its own. A strong co-signer may help you secure a better rate.
What documents are required?
Typically your current loan statement, vehicle info (VIN, mileage), proof of income, insurance, and government ID.
