About Autopay

Autopay, formerly known as RateGenius, was founded in 2007 in Austin, Texas (now headquartered in Denver) and has facilitated over $5 billion in auto loan refinancing through its marketplace model. Like Splash Financial for student loans, Autopay is not a lender. It operates as an intermediary that distributes your application to a network of banks, credit unions, and online auto lenders who compete for your business. Autopay earns referral fees from the lending partners, not from borrowers. The company rebranded from RateGenius to Autopay in 2022 to reflect an expanded product line that includes new car financing, used car financing, and lease buyout loans alongside its core refinancing product. The auto loan refinancing use case is compelling because dealership financing is systematically overpriced. Dealers earn profit through rate markup: the lender approves you at 5%, the dealer quotes 8%, and the 3% spread is split between the dealer and the lender as a kickback. This practice is legal and nearly universal, which means most buyers who financed through a dealership are paying 2-4% above the rate they could qualify for independently. Autopay's marketplace connects these over-charged borrowers with lenders willing to refinance at the lower rate. A single application generates 2-5 competing offers, and Autopay handles the entire payoff process with the existing lender including title transfer. Autopay's minimum credit score of 550 and APR range starting at 5.19% suggest a wide borrower base, but the best rates require 720+ scores and vehicles under 7 years old with fewer than 100,000 miles. Older vehicles, high-mileage cars, and subprime borrowers will see significantly fewer offers and higher rates. Cash-back refinancing is available for borrowers whose vehicle is worth more than their loan balance, essentially allowing you to borrow against vehicle equity for any purpose. However, this extends your loan term and increases total interest paid, so it should only be used when the alternative is a higher-rate form of credit like credit cards.

Notable Case Studies

Dealership Markup Refinance

A buyer with a 690 FICO financed a 2023 Honda CR-V through the dealership at 11.4% APR over 72 months with a $28,500 balance. The dealer had marked up the rate from the bank's approved 6.9% by 4.5 percentage points. Monthly payment: $554. After 8 months of payments, the remaining balance was $26,800 and the borrower's credit score had improved to 710.

Autopay generated four refinancing offers. Best offer: a credit union at 5.89% APR over 60 months. Monthly payment: $517, saving $37/month. Total remaining interest on the old loan: $12,600 over 64 months. Total interest on the new loan: $4,220 over 60 months. Net savings: $8,380 in interest and paid off 4 months earlier. Autopay handled the payoff to the original dealer-financing bank and the title transfer to the new credit union. The entire process took 7 business days from application to funding.

Cash-Back Refinance for Emergency Expenses

A borrower had a 2022 Toyota Tacoma with a loan balance of $24,000 at 8.2% APR. The truck was valued at $33,000 (KBB), providing $9,000 in equity. The borrower needed $5,000 for an emergency medical expense and was considering a personal loan at 18% APR or a credit card cash advance at 25.9%.

Autopay arranged a cash-back refinance of $29,000 at 6.49% APR over 66 months through a lending partner. The borrower received $5,000 in cash and the new loan paid off the existing $24,000 balance. Monthly payment: $497 versus $492 on the old loan (only $5/month increase). Total cost of the $5,000 cash-back: approximately $1,200 in additional interest over the loan term, versus $2,700 for a 36-month personal loan at 18% APR or $3,900 on a credit card over the same period. The cash-back refinance saved $1,500-$2,700 compared to alternatives while also lowering the rate on the existing balance.

Pros & Cons

Pros

  • Marketplace model generates 2-5 competing offers from one application, introducing price competition that consistently beats the rate buyers originally received from dealership financing
  • No platform fees to borrowers: Autopay earns from lender referral fees, so the service itself is free and the rates you see are the actual rates from lending partners
  • Full payoff management means Autopay handles paying off your existing lender, managing the title transfer, and coordinating with the new lender, making the refinance process nearly hands-off
  • Cash-back refinancing allows borrowers with vehicle equity to access cash at auto loan rates (5-10%) rather than personal loan rates (14-18%) or credit card rates (22-28%), providing a low-cost emergency funding source
  • Minimum credit score of 550 and verified client reputation indicate both accessibility and operational reliability, with only 290 CFPB complaints over three years, which is exceptionally low for the company's volume

Cons

  • As a marketplace, the final lending experience depends entirely on the partner you select. Customer service quality, payment portal usability, and issue resolution vary by lender and Autopay cannot intervene after funding
  • Older vehicles (8+ years) and high-mileage cars (100,000+ miles) receive significantly fewer offers or no offers at all, as many lenders restrict refinancing to newer vehicles with sufficient remaining useful life
  • Some lending partners impose minimum loan balance requirements ($7,500-$10,000), which means borrowers close to paying off their existing loan may not qualify for refinancing even if the rate savings are substantial
  • Cash-back refinancing extends your loan term and increases total interest paid, which can lead to being underwater (owing more than the car is worth) if the vehicle depreciates faster than expected

Frequently Asked Questions

Savings depend on the gap between your current rate and the refinanced rate, your remaining balance, and the new term length. The typical Autopay customer saves $75-$150/month according to company data. On a $25,000 balance, dropping from a dealer rate of 10% to a refinanced rate of 6% saves approximately $5,500 in interest over 60 months. The largest savings come from borrowers who financed through dealerships, as dealer markup adds 2-5% above the lender's approved rate. If you financed through a credit union at a competitive rate originally, the refinancing savings will be modest or nonexistent.
The optimal timing depends on three factors: (1) your credit score has improved since the original financing, which qualifies you for a lower rate tier; (2) market rates have dropped below your current rate; or (3) you financed through a dealership and have never comparison-shopped the rate. Wait at least 60-90 days after purchase before refinancing, as some lenders require a seasoning period. Avoid refinancing if your remaining balance is under $7,500 (too small for most lenders), your car is over 7 years old or has over 100,000 miles (limited lender appetite), or you are more than halfway through your loan term (savings are front-loaded due to amortization).
The initial Autopay application uses a soft credit pull that does not affect your score. When you select a lender and proceed, the lender will do a hard credit inquiry, which typically drops your score by 2-5 points temporarily. The old loan being paid off and the new loan opening will appear on your credit report, which may temporarily affect your account age and mix. Within 2-3 months, most borrowers see their score recover or improve, because the on-time payments on the new lower-rate loan offset the hard inquiry. Multiple auto loan inquiries within a 14-day window are typically treated as a single inquiry by FICO scoring models.
If your vehicle is worth more than your current loan balance, you can refinance for a higher amount and receive the difference as cash. Example: your car is valued at $30,000 and your loan balance is $22,000. You could refinance for $26,000, receiving $4,000 in cash while the new loan pays off the $22,000 balance. The cash-back amount is limited by the lender's maximum loan-to-value ratio (typically 125% of vehicle value) and your creditworthiness. Interest accrues on the full $26,000, so you are paying auto loan rates on the cash portion. This is cheaper than personal loans or credit cards for emergency cash but more expensive than not borrowing at all.
Most lenders in the Autopay network require the vehicle to be 10 years old or newer, under 150,000 miles, and have a minimum loan balance of $5,000-$10,000. The best rates and most offers go to vehicles that are 1-5 years old with under 60,000 miles. Luxury vehicles, trucks, and SUVs with strong resale values may receive better terms than sedans that depreciate quickly. Salvage-title vehicles, vehicles with rebuilt titles, and commercial vehicles (like work vans or trucks over 1 ton) are generally ineligible. RVs, motorcycles, and boats are not covered by the standard auto refinancing marketplace.
