Recent data from Caribou reveals that American motorists collectively overpay an estimated $54 billion each year on their auto loans. The primary reason: most borrowers accept the first rate offered at the dealership instead of comparing alternatives, much like many homeowners do for mortgages.
Why Refinancing Matters
Refinancing an existing auto loan allows drivers to secure a lower interest rate, extend the loan term, or both, resulting in a reduced monthly payment. Caribou’s analysis of refinance loans funded between April 1 and June 30, 2026 shows that borrowers who take this step can save hundreds of dollars each month.
States with the Biggest Savings
Drivers in Louisiana, New Mexico and Washington enjoy the highest average monthly savings after refinancing. These states also have some of the largest average original loan balances, meaning a refinance can produce a more pronounced impact on the monthly bill.
Fuel Type Differences
Diesel vehicle owners lead the savings chart, averaging $234 per month in reduced payments. Diesel trucks and SUVs typically carry higher price tags and larger loan balances, which amplifies the benefit of a lower rate.
Electric‑vehicle (EV) owners see an average monthly reduction of $190, up from $176 the previous year. Rising used‑EV values—up more than 5 % since early 2026—lower the loan‑to‑value ratio, putting borrowers in a stronger position to negotiate better rates.
Owners of gasoline‑powered and hybrid vehicles still realize meaningful savings, averaging $156 and $119 per month respectively.
Vehicle Style Impacts
Cars with higher loan balances tend to generate the strongest refinancing gains. Coupes, including popular sports models such as the Ford Mustang and Chevrolet Corvette, average $184 in monthly savings. Pickup trucks—one of the nation’s most financed vehicle types—average $183 per month, outpacing sedans, SUVs, vans, hatchbacks and wagons.
Generational Insights
Gen Z borrowers (ages 18‑31) face a tough financial backdrop, often juggling auto debt with student loans and housing costs. In Caribou’s Car Loan Sentiment Survey, 35 % of Gen Z respondents reported difficulty making a car payment on time in the past year—more than twice the rate of baby boomers (13 %). Despite these challenges, Gen Z achieved the steepest interest‑rate reductions, averaging a 5.34‑percentage‑point drop through refinancing.
Millennials enjoy the largest monthly payment savings of any generation, averaging $174 per month. The extra cash flow helps many address competing priorities such as child‑related expenses, caring for aging parents, or paying down other debt. When asked how they would use an additional $150 each month, millennials cited paying down other debt, building emergency savings and covering everyday costs like groceries and gas.
National Refinancing Trend
Refinance dollar volume doubled between Q2 2024 and Q2 2026, reaching $4.4 billion in the most recent quarter, according to Experian. More drivers are recognizing that the rate signed at the dealership is not necessarily the best rate available today, and that a simple rate change—without changing the vehicle—can free up significant household cash.
How to Get Started
Caribou provides an interactive state‑savings tool that lets consumers see average monthly savings for their area. Drivers interested in refinancing should compare offers, check their credit score, and consider the loan‑to‑value ratio of their vehicle. A lower ratio generally improves the likelihood of securing a better rate.
By taking a few minutes to shop around, American motorists can collectively keep billions of dollars from flowing into unnecessary interest payments, putting more money back into families and local economies.
