- ✓ Shop 3+ lenders — credit unions, online lenders, and bank pre-approvals often differ by 0.5–1.5% APR. Even small APR differences add up over 4 years.
- ✓ Watch the loan term — extending to 72 months to lower the monthly payment usually costs more in total interest. Try to keep the new term ≤ the current term.
- ✓ Factor in fees — title transfer, lien fees, and origination fees can run $100–$500. The break-even field on this page tells you how long until those fees pay off.
- ✓ Mind your credit score — a 720+ score typically unlocks the best auto refi rates. Below 600, refi rates are often worse than the original loan.
- ✓ Cash-out refi is rarely free — pulling equity out increases the loan balance and may flip you from "covered" to "underwater" if the car depreciates. Use only for high-ROI needs.
