How GM Financial bill pay works
GM Financial bill pay lets you send your monthly car payment through their website, mobile app, or by mail. You can set up a one-time payment whenever you want, or arrange automatic payments that come out on a date you choose each month. The payment goes directly to GM Financial, and you'll see it reflected in your account within one to two business days for online payments, or five to seven business days for mailed checks.
You don't need to sign up for a separate service — bill pay is built into your GM Financial account. Once you log in, you can choose your payment method (bank account transfer, debit card, or check), enter the amount, and pick the date the payment should arrive. If you set up autopay, GM Financial will pull the same amount on the same day each month unless you change it.
Key Takeaways
- Online payments through GM Financial's website or app typically post within one to two business days, while mailed checks take five to seven business days.
- You can make a one-time payment or set up automatic monthly payments from your bank account, debit card, or by mailing a check.
- Autopay removes the risk of forgetting a payment, but you must make sure your bank account has enough money on the scheduled date.
- If you pay early or extra, the additional amount goes toward your principal balance and reduces the total interest you'll pay over the life of the loan.
- Missing a payment triggers late fees and can damage your credit score, even if you catch up the next day.
Setting up online payments through your GM Financial account
Log into your GM Financial account on their website or open the GM Financial mobile app. Go to the "Make a Payment" or "Pay Now" section — the exact wording depends on which platform you're using. Enter the amount you want to pay, select your payment method (bank account or debit card), and choose the date you want the payment to go through.
If you're paying from a bank account, you'll need your routing number and account number. GM Financial will verify the account with a small test deposit, which takes one to two business days. Once verified, you can use that account for future payments. If you're paying by debit card, you'll enter the card number, expiration date, and CVV just as you would at any online store.
After you submit the payment, you'll get a confirmation number. Save this or take a screenshot — you'll need it if you ever need to contact GM Financial about that specific payment. The payment will show as "pending" in your account until it posts, which usually happens the next business day for bank transfers and the same day for debit cards.
Setting up automatic payments (autopay)
Autopay is the easiest way to make sure you never miss a payment. In your GM Financial account, look for "Automatic Payments," "Recurring Payments," or "Autopay" — the menu name varies. Select the bank account or debit card you want to use, enter the amount (usually your regular monthly payment), and choose the day of the month you want it to come out.
GM Financial will pull that amount automatically on the date you pick, every month, until you cancel it or change the amount. Most people choose a date a few days after they get paid, so the money is definitely in their account. If you choose the 31st of the month, GM Financial will process it on the last day of months that have fewer than 31 days.
You can change or cancel autopay anytime through your account. If you need to skip a month or change the amount, log in and update your autopay settings before the scheduled payment date. If you cancel autopay, you'll need to make manual payments going forward, so set a reminder on your phone or calendar.
Paying by mail
If you prefer to mail a check, write it to GM Financial and include your account number on the memo line. Your payment coupon (if you receive one) has the mailing address and your account number printed on it — use that. If you don't have a coupon, you can find the mailing address in your loan documents or by calling GM Financial's customer service.
Mail your check at least seven to ten business days before your due date to account for mail delivery time. The post office typically takes three to five business days to deliver mail, and GM Financial may take another one to two business days to process it once it arrives. If your payment arrives after the due date, it will be considered late even if you mailed it on time.
Keep a copy of the check or take a photo of the front and back before you mail it. If the check gets lost in the mail, you'll have proof you sent it. You can also ask your bank to stop payment on a check if you need to cancel it, though you'll still owe the money to GM Financial.
What happens if you miss a payment
If your payment doesn't arrive by the due date, GM Financial will charge a late fee. The amount of the late fee varies by state and your loan agreement, but it's typically a percentage of your monthly payment or a flat dollar amount — check your loan documents to see what yours is. The late fee is added to your balance and you'll owe it along with your next payment.
A late payment also gets reported to the credit bureaus (Equifax, Experian, and TransUnion) and will show up on your credit report. This can lower your credit score by 50 to 100 points or more, depending on how late the payment is and your overall credit history. The damage is worst if you're 30 or more days late.
If you're 60 days late, GM Financial may start calling you and sending letters. If you're 90 days late, they can begin repossession proceedings, meaning they can legally take the car back. Even if you pay the missed amount the next day, the late payment stays on your credit report for seven years. If you know you'll be late, call GM Financial before the due date — they may be able to work out a payment plan or extend your due date.
Paying extra or paying off early
You can pay more than your monthly payment amount anytime, and the extra goes directly toward your principal balance. This reduces the total amount of interest you'll pay over the life of the loan and can shorten your loan term. For example, if you pay an extra $50 per month, you could save hundreds or thousands in interest depending on your interest rate and how much time is left on the loan.
There is no penalty for paying off your loan early — GM Financial does not charge a prepayment fee. If you want to pay off the entire loan at once, log into your account and look for "Payoff Quote" or "Payoff Amount." This tells you the exact amount you owe as of a specific date, including any interest that has accrued. The payoff amount changes daily as interest accumulates, so get a fresh quote right before you make the final payment.
When you pay off the loan, GM Financial will release the lien on your car's title. This means you own the car free and clear. The title release can take one to two weeks to arrive in the mail, depending on your state's DMV process.
Payment methods and fees
GM Financial accepts payments by bank account transfer (ACH), debit card, and mailed check. Bank account transfers are free and usually the cheapest option. Debit card payments may carry a small fee — typically $1 to $3 — depending on GM Financial's current policy. Mailed checks are free, but you pay for the postage and risk mail delays.
Some third-party payment processors (like PayPal or other bill pay services) may offer to send your GM Financial payment, but these often add their own fees on top. It's usually cheaper to pay directly through GM Financial's website or app. If you use a credit card payment service to pay your car loan, be aware that most credit card companies treat this as a cash advance, which comes with a higher interest rate and an upfront fee.
Frequently Asked Questions
Can I change my payment due date?
GM Financial may allow you to change your due date once per year, depending on your loan agreement. Contact their customer service to ask about moving your due date to a day that works better with your paycheck schedule. Some lenders will do this at no cost, while others may charge a small fee.
What if I pay online but the payment doesn't show up in my account?
Check your confirmation number and the status in your GM Financial account — it may still be pending. Online payments typically post within one to two business days. If more than two business days have passed and the payment still shows as pending, contact GM Financial with your confirmation number. They can trace the payment and tell you where it is.
Is autopay safe?
Autopay is as safe as any automatic bank transfer. GM Financial uses encryption to protect your account information, and your bank account details are not shared with third parties. The main risk is overdrafting your bank account if you don't have enough money on the scheduled payment date, so make sure your account balance covers the payment before autopay pulls it.
Can I make a payment if I'm behind on my loan?
Yes, you can make a payment anytime, even if you're behind. However, the payment will be applied to your oldest debt first (the oldest missed payment), not to the current month's payment. If you're significantly behind, contact GM Financial to discuss a payment plan or catch-up arrangement before making payments on your own.
Do I need to pay the full monthly payment, or can I pay part of it?
You can pay any amount you want, but your loan agreement requires a minimum monthly payment. If you pay less than the minimum, the difference will be added to your balance and you'll be considered late. If you're having trouble making the full payment, contact GM Financial to discuss your options before the due date.
