Should You Refinance Your Car Loan? Use an Auto Refinance Calculator to Find Out

SmartCalc Logo

For many drivers, a car payment is one of the biggest monthly expenses after housing. But what if you could lower that payment — or pay off your loan faster — by refinancing? With an Auto Loan Refinance Calculator, you can quickly see if refinancing your auto loan makes sense for you.

Why Refinance a Car Loan?

Refinancing replaces your current auto loan with a new one, ideally at a better interest rate or with a different loan term. People often refinance to:

 

  • Lower their interest rate if credit scores have improved.
  • Reduce their monthly payment by extending the loan term.
  • Pay off the loan faster by choosing a shorter term.
  • Free up cash flow to use for other expenses.

 

But refinancing isn’t always the right choice. That’s why it’s important to run the numbers before applying.

How an Auto Refinance Calculator Helps

An auto refinance calculator lets you compare your current loan to a new scenario side by side. By entering:

 

  • Your current loan balance and payment
  • And the details of the refinance loan term

 

…the calculator shows your new monthly payment, monthly savings, and a payoff table to show you the interest you will pay if you refinance your vehicle.

Example: $20,000 Auto Loan

  • Current loan: $20,000 balance, 8% APR, 48 months left
  • New loan: 6% APR, 48 months

 

Results:

 

  • Old payment: $488/month
  • New payment: $470/month
  • Monthly savings: $18
  • Total interest savings: ~$430

 

Even small changes in APR can create noticeable savings — and bigger drops can save thousands.

When Refinancing May Not Make Sense

While refinancing can save money, it’s not always the best move:

 

  • Older or high-mileage vehicles – Some lenders limit refinancing eligibility.
  • Extending the term too far – Lowers payments but may increase total interest.
  • High refinance fees – Costs can outweigh savings if you don’t plan to keep the car long.
  • Upside-down loans – If you owe more than the car is worth, options may be limited.

Frequently Asked Questions

Does refinancing hurt my credit score?

There may be a small, temporary dip from the credit check, but on-time payments after refinancing can improve your score.

 

Can I refinance with bad credit?

Yes, but your new rate may not be much better than your current one. Improvements come with better credit profiles.

 

How soon can I refinance an auto loan?

Some lenders allow refinancing right away, but most recommend waiting 6–12 months so you have payment history.

 

Do I need to use my original lender?

No. You can shop around with banks, credit unions, or online lenders to find the best refinance terms.
