Should You Refinance Your Car Loan?
Refinancing makes sense if rates have dropped at least 0.5-1% since you got your original loan. The math is simple: a lower interest rate means lower monthly payments and less interest paid overall. But refinancing isn't automatic. You need to run the numbers first.
When Refinancing Makes Sense
Refinancing works best when:
| Factor | Best Case |
|---|---|
| Rate drop | 0.5-1% or more |
| Time remaining | 3+ years on loan |
| Credit score | Improved since purchase |
| Loan balance | At least $10,000 |
If you have only 1-2 years left on your loan, refinancing may not save enough to justify the fees and paperwork.
Calculate Your Actual Savings
Refinancing costs money upfront. Most lenders charge 0-1% of your loan balance in fees, which adds $100-$300+ to your balance. You also pay for a credit report and possibly an appraisal.
Here's how to decide:
- Find your current monthly payment and interest rate
- Get refinance quotes showing the new payment and rate
- Calculate monthly savings: subtract new payment from old payment
- Divide refinance fees by monthly savings
- If the result is fewer months than you're keeping the car, refinance
Example: Your old payment is $450 monthly at 6.5%. A new loan offers $425 monthly at 4.8%. Your monthly saving is $25. If refinance fees total $300, you break even in 12 months ($300 ÷ $25 = 12). If you're keeping the car 3+ years, it's worth it.
What Happens to Your Credit
Refinancing creates a hard inquiry that may drop your credit score by 5-10 points temporarily. But it also counts as a new account, which can impact your credit mix. The good news: the score hit is usually temporary. After 6 months, most of the impact disappears.
If your credit score has improved since you bought the car, you'll likely qualify for better rates. Better credit scores get lower interest rates.
Watch Out for These Traps
Some car loans have prepayment penalties that charge you for paying off the loan early. Check your loan agreement before refinancing. A $500 penalty could wipe out your savings.
Also, refinancing resets your loan term. If you extend from 48 months remaining to 72 months, you pay less per month but more interest overall, even at a lower rate.
