Auto Refinance Calculator

Refinancing your car loan can lower your interest rate and save hundreds or even thousands over the life of your loan. This is especially true if you originally signed with a dealership, or your credit score has improved since taking out your auto loan. No matter the circumstance, it is worth your while to calculate savings and compare auto refinancing rates.

Use the auto loan refinance calculator to find potential savings

Bankrate’s auto refinance calculator can help you determine how much you could save on interest, monthly payments or both. 

  1. Input details. Simply enter the details of your current loan: your monthly payment, remaining balance, interest rate and the remaining loan term.
  2. Compare rates. After figuring out what adjusted term and interest rate work best for you and your wallet, compare lenders that offer auto refinance.
  3. Apply for preapproval. Get preapproved with multiple lenders to see potential rates — and determine if they meet your needs. This way, you can calculate if refinancing will really save you money compared to your current loan.

What refinancing is and how it works

Refinancing allows you to replace your current loan with a new one. If you are able to qualify for lower rates and opt for a shorter — or equivalent — term, you may reduce your monthly payment and the total amount of interest you pay. 

While many people can qualify for better rates through refinancing, it’s not always the case. Lenders may require you to meet specific requirements to refinance, including: 

  • A history of on-time payments.
  • A good personal credit score.
  • Less than 100,000 miles on vehicle.
  • Vehicle less than 10 years old.
  • Current loan meets the minimum refinance amount.

The choice to refinance does not come without risk, however. If you choose to refinance at a similar rate but opt for a longer term, you are more likely to become upside-down. To avoid this, stay away from long repayment terms — which can feel enticing when refinancing for a smaller monthly payment. 

When should you refinance an auto loan?

Deciding to refinance your auto loan comes down to saving money on interest, reducing your monthly payment or both. Consider these situations when determining when you should  refinance your current auto loan:

  • You received dealer financing. Dealers often add a few points as a commission. If your original loan was financed by your car dealer’s preferred lenders, there is a good chance you didn’t score the best rate possible. 
  • Your credit score improved. A difference of just 30 points on your credit score can make a significant impact on your rate. If your score has improved since your original auto loan, you may save money by refinancing. 
  • You want to lower your payment. Refinancing for a longer loan term can reduce your monthly payment. However, it will increase the amount of interest you pay. Ideally, you should lower your payment by sticking with a term similar to the amount of time you have left at a lower interest rate.
  • National interest rates are low. When the federal funds rate is low, auto loan rates will also be more competitive. This is unfortunately not the case right now as the Federal Reserve has increased rates for 10 straight meetings, meaning a higher cost for lenders to borrow.
  • You have equity in your car. Lenders see positive equity, when your vehicle is worth more than you owe, as a plus. If you fall into this category you might get offered lower rates. 

How to apply for an auto refinance loan

The process of refinancing your auto loan is fairly similar to the process that came with applying for your initial vehicle loan. Follow these five steps before signing off on a new refinanced auto loan.

  1. Decide if refinancing is best for you financially. Compare your current monthly cost with potential savings from the refinancing process.
  2. Review your current loan. Understand your current rate and loan term to determine how much you will pay in interest.
  3. Determine the value of your car. Use tools like Kelley Blue Book and Edmunds to find out how much your car is worth
  4. Shop around. Compare refinancing options of at least three different lenders and apply for preapproval to preview your rates.
  5. Sign off on the new loan. Choose a loan and walk away with an updated term and rate — but only if you will lower your monthly payment or pay less in interest.
