Why it might be time to refinance

In February 2020, according to Edmunds the average APR (annual percentage rate) on a new car loan was 5.6%. and the average used car loan was 8.3%.

The Federal Reserve made another emergency cut to interest rates, dropping the rate by 1% to a range of 0-.25%.  A lower fed rate encourages lenders to offer lower rates to consumers for both new car loans and refinancing.

Check to see how low refinancing rates are now.

But aside from government moves, people simply aren’t making big purchases like new cars. As a result, auto lenders don’t have the usual volume of new car loans.  This means they need to get more business elsewhere, like making refinancing deals more attractive to consumers.

How much can you save by refinancing your car loan?

According to Credit Karma, a $25,000 vehicle financed for 60 months at 7% has a payment of $495 per month and a total financing cost of $29,702 over the life of the loan.  If you refinanced $21,000 in year 2 at 5%, you'd pay about $484 per month with a total financing cost of $23,214 (for the remaining 48 months).  That’s a difference of $2,488 between the two options.

When does refinancing your car loan make sense?

When does refinancing your car loan make sense?Here are three reasons it may be time to refinance.

Reason 1 - If interest rates have dropped

Interest rates are always changing.  So keep an eye on rates and you may be able to save some money.

A good rule of thumb is if rates have dropped 2% or more and you have at least $10,000 outstanding, then refinancing is worth considering.

Reason 2 – If you have a high interest loan

If you didn’t get a financing deal with a low APR when you bought your car you may be paying a higher interest rate than the average car buyer.

Reason 3 - If you have improved your credit

Auto lenders use your credit score to determine your interest rate.   If you had a poor credit score or bought a car as a student with no prior credit history your loan payments may be inflated.

If you’ve improved your credit and have been making your car payments on time, you may now qualify for a lower rate.

Where can you refinance?

Not all lenders offer auto refinancing.  However, one of my sponsors, SuperMoney, pulls together offers from those lenders that do.

They present offers from several different online lenders and you can check rates and pick the best offer.

When shouldn't you refinance?

When you shouldn't refinance?Refinancing a car loan may not always be a good idea.  You may want to hold off for these reasons.

Reason 1 - If you are towards the end of your loan

If you’ve paid off most of your car already there is less value in refinancing.  Loan payments usually contain a higher portion of interest earlier in the life of the loan.  As you get towards the end of the loan your payment will mostly be principal.    As a result, you won’t be able to save as much on interest if you refi towards the end of your loan.

A good rule of thumb is to skip refinancing if you have less than 2 years left on your loan.

Reason 2 - If your car has high mileage

Some auto lenders will only allow refinancing if your car is less than 7 years old or hasn’t exceeded a mileage cap (likely around 100,000 miles or so).  This is because the loan is secured by an asset (your vehicle) that can be repossessed if you don’t pay.   The more your car has depreciated, the lower the value of the asset needed to secure the loan.

Reason 3 - If you will incur fees

Occasionally, car loans have prepayment penalties for paying them off early.  If that is the case, read the fine print as the fees may exceed any interest savings.

Some lenders may also charge you fees to refinance. So again, you’ll want to evaluate any fees against the amount you will save.
