Klarna and Afterpay both let US shoppers split a purchase into 4 interest-free payments, but the timing differs. Klarna takes the first payment when your order ships and the other three every 2 weeks, while Afterpay takes the first payment upfront and the rest over six weeks. As of October 2026, Klarna lists a late fee of up to 7 dollars, with all late fees capped at 25% of the order, and Afterpay says there are no late fees on Pay in 4 when you pay on time.
For shoppers and for small online shops deciding which button to offer, the differences sit in the small print. I read Klarna's US Pay in 4 page and Afterpay's US how-it-works page. Here's how they compare, as of October 2026.
Klarna and Afterpay compared
| Klarna Pay in 4 | Afterpay Pay in 4 | |
|---|---|---|
| Payments | 4 interest-free payments every 2 weeks | 4 interest-free installments, generally over six weeks |
| First payment | Taken when your order ships | Paid upfront |
| Credit check | A soft credit check that doesn't affect your score | Eligibility criteria apply |
| Late fees | Up to 7 dollars per missed payment after a retry, capped at 25% of the order | None when you pay on time; late payments capped |
| Other options | Pay in 30 days and pay over time | Pay Monthly loans, where a finance fee may apply |
| In store | At partner stores | With the digital Afterpay Card in Apple Wallet or Google Wallet |
| Who can use it | US residents aged 18 or over (or legal age in their state) | US residents aged 18 or over |
When the money leaves your account
This is the difference that catches people out. Klarna's page says the first payment is taken from your card or bank account when your order is shipped, then the remaining three are charged automatically every 2 weeks. Afterpay's page says you make the first payment upfront and pay the rest over six weeks. So with Klarna, a pre-order or a slow shipment delays the whole schedule; with Afterpay, a quarter of the total goes at checkout.
What happens if you miss a payment
Klarna spells out its process: it'll let you know if a payment fails, try once more, and if it still can't collect, add the amount to your next payment along with a late fee of up to 7.00 dollars. Its page says your total late fees will never exceed 25% of your order value. Klarna also says it runs a soft credit check for Pay in 4, which doesn't affect your credit score and isn't visible to other lenders.
Afterpay's page says there are no late fees when you pay on time on Pay in 4, that it sends reminders and caps late payments, and its small print adds that late fees may apply and a finance fee may apply to certain transactions. Its Pay Monthly example shows an APR that could be 36%, which is a very different product from Pay in 4, so don't confuse the two at checkout.
Which to use
- You're buying something that ships later: Klarna, because the first payment waits for shipping.
- You want the plan settled from the start: Afterpay, with the first payment at checkout.
- You shop in store with your phone: Afterpay's digital card works in Apple Wallet and Google Wallet.
- You're worried about missing a date: know that Klarna caps total late fees at 25% of the order.
- You run a shop: offer whichever your customers already use, and keep the other in mind for bigger baskets.

My advice on Klarna or Afterpay
Treat both as a way to spread a purchase you could pay for today, not as extra money. If you use either, set up reminders and pay on time, because that's when both stay interest-free and free of late charges. For shop owners, the right choice is the one your customers already recognise, so check what your checkout data says before you add a second button.
