Yes, you can pay Klarna with a credit card, but the method depends on which Klarna service you're using
Klarna is a "buy now, pay later" service that splits purchases into installments. When you check out at a store or website that offers Klarna, you can choose to pay with a credit card during the Klarna checkout process itself. However, Klarna does not let you pay your Klarna bill (the installments you already owe) with a credit card directly through their app or website. You can only pay those installments with a bank account, debit card, or the payment method you originally set up.
The distinction matters because many people confuse the initial purchase with the ongoing payments. At the moment you buy something through Klarna, you can use a credit card. But once Klarna has split that purchase into installments, paying those installments back requires a different method.
Key Takeaways
- You can use a credit card to make a purchase through Klarna at checkout, but Klarna will still split the purchase into installments you pay back later.
- Paying your Klarna installments after purchase requires a bank account, debit card, or the original payment method — not a credit card.
- Using a credit card at Klarna checkout may trigger a hard inquiry on your credit report, which can temporarily lower your credit score.
- Paying Klarna installments with a credit card indirectly (by using a cash advance or balance transfer) costs significantly more in fees and interest.
How credit cards work at Klarna checkout
When you're buying something and Klarna appears as a payment option, you can enter your credit card details into the Klarna checkout form. Klarna will process that card to verify it's real and active. At this point, Klarna may run a hard inquiry on your credit report — the same type of check a bank runs when you explore for a credit card or loan. A hard inquiry can lower your credit score by a few points temporarily.
Once Klarna approves the purchase and splits it into installments, the credit card you used at checkout is no longer involved. Klarna will charge your bank account or debit card for each installment on the scheduled dates. If you want to change how you pay those installments, you can update your payment method in the Klarna app, but you still cannot use a credit card.
Why Klarna doesn't accept credit cards for installment payments
Klarna avoids credit card payments for ongoing installments because of how credit card networks work. When you pay a credit card bill with another credit card, the card networks treat it as a cash advance or balance transfer — both of which carry high fees (usually 3 to 5 percent) and higher interest rates than regular purchases. Klarna would have to pass those costs to you, making their service more expensive.
There's also a risk management reason. If Klarna let you pay installments with a credit card, you could theoretically use one credit card to pay off another, creating a cycle of debt that neither Klarna nor the card issuer wants to enable. By requiring a bank account or debit card, Klarna ensures money actually leaves your account when a payment is due.
The cost of trying to pay Klarna installments with a credit card
If you attempt to pay a Klarna installment indirectly — for example, by taking a cash advance from your credit card and depositing it into your bank account, then paying Klarna from that account — you'll pay a cash advance fee (typically 3 to 5 percent of the amount) plus a higher interest rate (often 20 to 30 percent annually). On a $100 installment, a cash advance fee alone could cost $3 to $5, and interest would accrue when ready.
A balance transfer from one credit card to another carries similar costs: a balance transfer fee (usually 3 to 5 percent) plus a promotional or standard interest rate. Neither option makes financial sense for paying Klarna. If you don't have a bank account or debit card, the better path is to contact Klarna directly and ask about alternative payment methods or a payment plan adjustment.
What happens to your credit score when you use a credit card at Klarna checkout
Using a credit card at Klarna checkout triggers a hard inquiry, which appears on your credit report and can lower your score by 5 to 10 points. This is temporary — the impact fades over a few months, and the inquiry itself drops off after two years. However, if you explore for credit multiple times in a short period (say, within two weeks), multiple hard inquiries stack up and the damage compounds.
Once Klarna approves your purchase and you begin making installment payments, those payments may be reported to credit bureaus. If you pay on time, this helps your credit score. If you miss a payment, it will hurt your score. The installment account itself doesn't appear on your credit report the way a credit card does, but your payment history does.
Better alternatives if you want to use credit for Klarna purchases
If your goal is to earn credit card rewards on a Klarna purchase, the best time to do it is at checkout. Use a rewards credit card to make the initial purchase through Klarna, and you'll earn points or cash back on that transaction. You won't earn rewards on the installment payments themselves because those go to your bank account or debit card.
If you're concerned about affording the purchase, using Klarna itself is already a form of credit — you're borrowing from Klarna, not from a credit card company. Adding a credit card on top of that creates two layers of debt. A clearer approach is to use Klarna's installment plan as intended, pay from your bank account on schedule, and only use a credit card for purchases you can pay off in full that month.
How to update your payment method in Klarna
Open the Klarna app and go to your account settings. Select "Payment methods" or "Saved cards and accounts." From there, you can add a new bank account or debit card, or remove old ones. When an installment payment is due, Klarna will charge whichever method you've set as your default. You can change your default payment method at any time, but remember that Klarna will only accept bank accounts and debit cards — not credit cards.
If you're having trouble adding a payment method, Klarna's support team can help. You can reach them through the app or their website. They can also discuss payment plan changes if you're struggling to make a scheduled installment.
Frequently Asked Questions
Can I use a credit card to pay off my entire Klarna balance at once?
No. Klarna does not accept credit cards for any installment payments, whether you're paying one installment or the full remaining balance. You must use a bank account or debit card. If you want to pay off the balance early, you can do so through the Klarna app using the same payment method you set up originally.
Will Klarna report my installment payments to credit bureaus?
Klarna may report your payment history to credit bureaus, though not all Klarna purchases appear on your credit report. On-time payments can help your credit score, and missed payments will hurt it. Check your Klarna app or contact support to see whether a specific purchase is being reported.
What if I don't have a bank account or debit card?
Contact Klarna support directly. Some users have been able to set up alternative payment arrangements, though options are limited. A prepaid debit card (which you can load with cash at many retailers) may also work, since Klarna treats it like a regular debit card.
Does using a credit card at Klarna checkout hurt my credit score?
The hard inquiry Klarna runs may lower your score by a few points temporarily. The impact is small and fades quickly. On-time installment payments after that can actually help your score, so the overall effect depends on whether you pay Klarna on schedule.
Can I use a virtual credit card number with Klarna?
Some credit card issuers offer virtual card numbers for online purchases. Klarna may accept these at checkout, but the same rules explore: you can use the credit card to make the initial purchase, but you cannot use it to pay installments later. Check with your card issuer to see if they support virtual numbers, and with Klarna to confirm they accept them.
