Most car lenders won't take credit card payments directly, but you have workarounds
Your car lender almost certainly does not accept credit cards at the payment portal. Lenders avoid this because credit card processing fees cut into their revenue, and they want you paying from a bank account where the money is certain. But you can still route a credit card through a third party: a payment processor, a cash advance service, or your own bank's bill pay system. Each method costs something different and takes a different amount of time, so the choice depends on whether you need the transaction fast, whether you want to preserve your credit card's cash advance limit, and how much you are willing to pay in fees.
The most common routes are payment processors like Plastiq (which charge a percentage fee), your bank's bill pay system (which is free but slow), or a cash advance (which is expensive but immediate). Paying your car loan with a rewards credit card only makes financial sense if the rewards rate exceeds the fee you pay to process the payment.
Key Takeaways
- Payment processors like Plastiq and Square Cash let you send credit card money to almost any biller, but charge 2% to 3% of the payment as a fee.
- Your bank's bill pay system can mail a check from your checking account to your lender at no cost, but takes 5 to 10 business days to arrive.
- Credit card cash advances let you withdraw money as cash and pay your lender directly, but charge interest immediately and count against your cash advance limit.
- Paying your car loan with a rewards credit card only makes financial sense if the rewards rate exceeds the fee you pay to process the payment.
Using a third-party payment processor
Payment processors like Plastiq, Square Cash, and PayPal act as intermediaries between you and your lender. You give them your credit card information, they charge your card, and they send the money to your lender by check or bank transfer. The transaction usually completes within 1 to 3 business days. You can typically schedule payments in advance or make them on demand.
The cost is a percentage fee taken from your payment amount. Plastiq charges 2.5% for most payments. Square Cash charges 2% for transfers to bank accounts and 3% for credit card payments. PayPal's rate varies by transaction type but typically runs 2% to 3%. On a $400 car payment, a 2.5% fee costs you $10. On a $600 payment, it costs $15. These fees are not tax-deductible unless you itemize deductions and the payment qualifies as a business expense.
This method works best if you need the payment to reach your lender quickly and you want to earn rewards on the transaction. The downside is the fee eats into any rewards you earn. If your card earns 2% cash back, a 2.5% processing fee means you actually lose 0.5% on the transaction. Before you use a processor, confirm that your lender accepts payments from third parties—most do, but some require payments to come directly from you or your bank.
Paying through your bank's bill pay system
Most banks offer bill pay as a free service to checking account holders. You log into your bank's website, enter your car lender's address, and schedule a payment. Your bank prints a check and mails it to the lender. The payment takes 5 to 10 business days to arrive, depending on mail speed and your lender's processing time. Some lenders process checks faster than others, so the actual arrival time can vary.
The advantage is zero cost. The disadvantage is the delay. If your payment is due in three days and you use bill pay, the check may not arrive until after the due date. Late fees from your lender can be $25 to $50 or more, so bill pay only works if you plan ahead. Some lenders also charge a fee if they receive a check instead of an electronic payment, though this is less common than it used to be. Always check your loan agreement or call your lender to confirm whether they accept checks and whether there is a processing fee.
To use bill pay with a credit card, you would need to first transfer money from your credit card to your checking account. Most banks charge a fee for this (usually 3% to 5% of the amount), so you end up paying anyway. It is simpler to use a payment processor if you want to pay with a credit card and need the money to move quickly.
Taking a cash advance and paying directly
You can withdraw cash from your credit card at an ATM or bank teller, then mail a check or transfer the money to your lender from your bank account. This avoids the payment processor fee but introduces other costs. The cash advance arrives immediately, which makes this method useful only in emergencies when you need to pay your lender the same day.
Credit card cash advances charge interest immediately, with no grace period. Most cards charge a higher interest rate for cash advances than for purchases—often 3% to 5% higher. If your card's purchase APR is 18%, the cash advance APR might be 23%. Interest accrues from the day you withdraw the cash, not from your statement closing date. A $500 cash advance at 23% APR costs about $9.58 in interest for one month. If you repay it within a few days, the interest is lower, but it still accrues daily.
Cash advances also count against your cash advance limit, which is usually much lower than your credit limit. If your card has a $5,000 credit limit and a $1,000 cash advance limit, you can only withdraw $1,000 in cash even if you have $5,000 available to spend. This method makes sense only if you have no other way to pay and you can repay the cash advance within a few days. For routine car payments, it is almost always more expensive than other options.
Comparing the actual cost of each method
| Method | Cost per $400 payment | Time to reach lender | Best for |
|---|---|---|---|
| Payment processor (2.5%) | $10 | 1–3 business days | Quick payment with rewards earning |
| Bank bill pay | $0 | 5–10 business days | Planned payments with no time pressure |
| Cash advance (23% APR, 1 month) | ~$7.67 | Same day | Emergency payment only |
| Direct bank transfer from checking | $0 | 1–2 business days | Immediate payment without fees |
The cheapest option is always paying directly from your checking account if your lender accepts it. Most lenders do accept electronic transfers or automatic payments from a bank account. If you do not have a checking account or your lender refuses bank transfers, bill pay is free but slow. Payment processors cost money but are fast. Cash advances are expensive and should be a last resort.
When comparing methods, factor in both the direct fee and the time cost. A $10 processor fee on a $400 payment is 2.5%. If bill pay takes 10 days and you would otherwise be charged a late fee, the processor fee might be worth it. If your payment is not due for two weeks, bill pay saves you $10 and is the better choice.
When paying with a credit card makes financial sense
Paying your car loan with a rewards credit card only pencils out if the rewards you earn exceed the fee you pay. If you use a 2% cash back card and pay through a processor charging 2.5%, you lose 0.5% on the transaction. You would need a card earning at least 3% cash back just to break even. Most general-purpose rewards cards earn 1% to 2% on all purchases, so they do not earn enough to offset the processor fee.
Some cards offer bonus categories—for example, 3% cash back on "payments and purchases" or 5% on rotating categories. Check your card's terms to see whether car payments count as a bonus category. Most do not. Even if they do, the fee still eats into your gain. A 5% rewards card minus a 2.5% processor fee leaves you with a net 2.5% benefit, which is real money but not huge. Over a year of $400 monthly payments, that is $120 in net rewards—worth doing if you are already using the processor, but not worth switching methods just for that amount.
The math also depends on your interest rate. If you are paying 3% APR on your car loan, earning 2% cash back on a payment processor fee of 2.5% means you are paying 0.5% more in total cost to earn the rewards. If your car loan is at 8% APR, the same transaction costs you 0.5% more but you are already paying a much higher rate, so the relative impact is smaller. Run the numbers for your specific card and lender before committing to this strategy. A simple rule: if your card's rewards rate is less than 3%, paying through a processor is not worth it.
Frequently Asked Questions
Can I set up automatic credit card payments to my car lender?
No. Lenders do not accept recurring credit card charges because the fees are too high and the transactions are reversible. You would need to use a payment processor and set up recurring payments through them, which means paying the processor fee every month. For most people, automatic payments from a checking account are cheaper and simpler.
Will paying my car loan with a credit card hurt my credit score?
Paying on time with any method—credit card, check, or bank transfer—does not hurt your score. Your lender reports the payment to credit bureaus regardless of how you sent the money. The only risk is if the payment arrives late because you chose a slow method like bill pay and did not account for mail time.
What if my lender charges a fee for credit card payments?
Some lenders charge 1% to 3% to accept credit cards directly. If your lender offers this option, compare it to the payment processor fee. A lender charging 2% might be cheaper than a processor charging 2.5%, or vice versa. Always ask your lender whether they accept credit cards and what they charge before you commit to a payment processor.
Can I use a balance transfer to pay my car loan?
No. Balance transfers only work between credit cards and are meant for moving existing balances. You cannot use a balance transfer to send money to a third party like a car lender. You would need to use a cash advance, payment processor, or bank transfer instead.
Is it ever worth paying my entire car loan off early with a credit card?
Only if the rewards significantly exceed the processing fee and you can pay off the credit card balance immediately. A $15,000 payoff through a processor charging 2.5% costs $375 in fees. You would need to earn at least $375 in rewards to break even, which requires a 2.5% rewards rate or higher. Most cards do not earn that much on car payments, so this strategy rarely works unless you have an unusually high-rewards card.
