How to pay your CarMax bill

CarMax accepts payments through their online account portal, by phone, by mail, and in person at CarMax locations. The fastest method is logging into your CarMax account online and making a payment directly — this takes about five minutes and shows as processed the same day. If you prefer not to use the website, you can call CarMax customer service, mail a check to the address on your bill, or walk into any CarMax store with a payment.

Your bill arrives by mail or email depending on what you selected during setup. The due date is printed on the bill itself. If you miss the due date, CarMax will charge a late fee, which varies depending on your contract terms — check your paperwork or call to confirm the amount.

Key Takeaways

  • The online payment portal is the fastest way to pay and lets you see your balance and payment history in one place.
  • Phone payments take about ten minutes and work if you have your bill handy or know your account number.
  • Mailed checks should arrive at least five business days before your due date to avoid a late fee.
  • CarMax stores accept cash and card payments in person, though not all locations have payment kiosks — call ahead to confirm.
  • Setting up automatic payments through your bank or the CarMax portal prevents missed due dates.

Paying online through your CarMax account

Go to the CarMax website and select "Sign In" in the top right corner. Enter your username and password. If you have not set up an online account yet, select "Register" and follow the prompts — you will need your account number, which is on your bill or in any email CarMax has sent you.

Once logged in, look for "Manage My Account" or "Payments" in the menu. Select the option to make a payment. Enter the amount you want to pay (you can pay the full balance, the minimum, or any amount in between), choose your payment method (debit card or bank account), and review the details. Click "Confirm" or "Submit Payment." The payment processes when ready, though it may take one to two business days to show in your account balance.

Paying online also lets you see your full payment history, current balance, and due date in one place. If you plan to pay the same amount every month, most online portals let you set up automatic payments so you never have to remember the due date again.

Paying by phone

Call CarMax customer service at the number on your bill. Have your account number and the payment amount ready. A representative will walk you through entering your payment information over the phone — they will ask for your debit card or bank account details. The call usually takes about ten minutes.

Phone payments process the same day you call, though the balance may not update in your account until the next business day. If you call after hours, you may reach an automated system that lets you enter payment information directly without speaking to a person.

Paying by mail

Write a check or money order for the amount due and include it in an envelope with your bill stub (the part that shows your account number and balance). Mail it to the address printed on your bill — this address is specific to your region, so do not use an address from another bill or a website.

Mail payments take five to seven business days to arrive and process. To avoid a late fee, mail your check at least five business days before the due date. Include only the payment stub in the envelope; do not send the entire bill. If you lose the stub, write your account number on the check itself so CarMax can match it to your account.

Paying in person at a CarMax location

Find your nearest CarMax store using the store locator on the CarMax website. Bring your bill or account number and a payment method (cash, debit card, or credit card). Walk up to the customer service desk and tell them you want to make a payment on your account.

Not all CarMax locations have payment kiosks, so call the store ahead of time to confirm they accept payments. In-person payments process when ready, and you will receive a receipt on the spot. This method works well if you are already at a CarMax location or prefer to handle payments face-to-face.

Setting up automatic payments

Automatic payments remove the risk of missing a due date. Log into your CarMax online account, find the "Payments" or "Autopay" section, and select "Set Up Automatic Payment." Choose the amount (usually your full monthly payment), the day of the month you want it to come out, and your payment method. Confirm the details and submit.

Once set up, the payment will come out of your bank account or card on the same day each month. You can change or cancel automatic payments anytime by logging back into your account. If your payment amount changes (for example, if you make an extra payment that lowers your balance), you may need to adjust your autopay amount manually.

What to do if you miss a payment

If your payment is late, CarMax will charge a late fee. The amount depends on your contract, but it is typically between $10 and $25. You will see the fee added to your next bill or account statement.

Make the payment as soon as you can to stop additional fees from piling up. If you are having trouble making payments, contact CarMax customer service to discuss your options — some programs may be available to help you catch up, though this depends on your specific situation and contract terms.

Frequently Asked Questions

Can I pay my CarMax bill with a credit card?

Most CarMax payment methods do not accept credit cards online or by phone because of processing fees. However, you can use a credit card in person at a CarMax store. If you want to use a credit card for online or phone payments, call customer service to ask whether your region allows it.

How long does it take for a payment to show up in my account?

Online and phone payments process the same day and usually show in your account within one to two business days. Mail payments take five to seven business days to arrive and process. In-person payments show when ready on your receipt.

What if I pay more than the amount due?

The extra amount will be credited to your account and applied to your next payment. You can also request a refund of the overpayment by calling customer service, though some programs may keep the credit on file instead.

Can I change my payment due date?

Contact CarMax customer service to request a due date change. They can usually move your due date to a different day of the month, though this may only be done once per year depending on your contract.

What happens if I do not pay my bill?

Late fees will accumulate, and your account may be reported to credit bureaus, which can hurt your credit score. If payments remain unpaid for an extended period, CarMax may take further action according to your contract terms. Contact them when ready if you cannot make a payment.
