Use this refinance savings calculator to estimate how much you could save by refinancing your auto loan.
Want a Lower Monthly Payment?
Your interest rate is based on your credit score— and even a small improvement could save you $100-$300 per month and thousands over the life of your loan. Most buyers overpay because they don’t check their credit score. Check your credit score before you refinance.
When Should You Refinance Your Auto Loan?
Refinancing may be beneficial if:
- Refinancing can lower your monthly payment or reduce your total interest, but timing matters.
- You may benefit from refinancing if:
- Your credit score has improved
- Interest rates have dropped
- You want to lower your monthly payment
- You want to pay off your loan faster
- Using this calculator helps you compare your current loan with a new option to see if refinancing makes sense.
When It May Not Make Sense
Refinancing may not help if:
- Fees outweigh savings
- You extend the term significantly
- Your credit score has declined
Example Scenario
If you owe $18,000 at 7% APR with 48 months remaining, refinancing to 5% could lower your monthly payment and save hundreds in interest — depending on fees and term length.
Smart Refinance Tips
- Compare lender offers
- Check for prepayment penalties
- Review total interest savings
- Avoid extending loan length unnecessarily
Frequently Asked Questions About Auto Loan Refinancing
When should I refinance my car loan?
Refinancing may make sense if interest rates have dropped, your credit score has improved, or you want to reduce your monthly payment.
How much can refinancing save me?
Savings depend on your new interest rate and remaining loan balance. Even a small rate reduction can lower total interest costs over the life of the loan.
Does refinancing hurt your credit?
Refinancing may cause a temporary small drop in your credit score due to a hard inquiry, but responsible repayment can improve your credit over time.
Can I refinance if I owe more than the car is worth?
Some lenders allow refinancing of upside-down loans, but terms may vary. It’s important to compare options carefully.
How soon can I refinance after buying a car?
Many lenders allow refinancing after 3–6 months of on-time payments, though policies vary.
