It depends on which service you use, and the honest answer is that the rules are changing right now. As of mid-2026: Affirm reports its loans to credit bureaus, so on-time payments can help you and missed ones can hurt. Klarna and Afterpay generally don't report your payments to U.S. bureaus at all. But a BNPL bill that goes unpaid long enough can still be sent to collections, and that hurts no matter who the provider is.
Why the answer used to be "no" and isn't anymore
For years, Buy Now, Pay Later lived in a credit gray zone: the loans didn't show up on your credit report, didn't help you build history, and (mostly) didn't hurt you if things went sideways. That's ending, in pieces:
- Affirm now reports its loans, including Pay in 4, to Experian and TransUnion. Your payment behavior there is part of your credit file.
- Klarna and Afterpay currently don't report to U.S. credit bureaus. They've said publicly they're holding off until they're confident reporting helps responsible customers rather than hurting them.
- FICO launched BNPL-specific score models (FICO Score 10 BNPL) in late 2025 that factor BNPL loans in. Early FICO testing found most users' scores moved by only about 10 points or less, and lenders adopt new score models slowly, so the full effect will take years to reach the score your lender actually pulls.
The short version: BNPL is becoming normal credit. Plan accordingly.
Provider details here were current as of July 2026. BNPL reporting varies by provider, product, and bureau and changes often, so confirm the current terms on each provider's own disclosures (Affirm, Klarna, and Afterpay) before you rely on them.
The ways BNPL can help your credit
- On-time payments with a reporting provider (like Affirm) build payment history, the biggest factor in your score. For people with thin credit files, this is a real, legitimate building block.
- BNPL-inclusive score models group your loans sensibly. FICO's approach bundles multiple small BNPL loans rather than treating each as a separate account, so normal use isn't punished as "lots of new accounts."
The ways it can hurt
- A missed payment with a reporting provider can land on your credit report like any other late payment.
- Collections is the universal risk. Even non-reporting providers can send seriously unpaid balances to a collection agency, and collections show up on your report regardless of the original lender's policy. "They don't report" means they don't report payments; it's not immunity.
- Loan stacking. BNPL's real danger is volume: five loans at once across three apps, each small, collectively bigger than you'd have put on a card. Every installment is a bill that can go 30 days late.
- Some BNPL applications involve credit checks. Pay-in-4 typically uses a soft check (no score impact), but longer-term BNPL financing can involve a hard inquiry. The provider has to tell you; look before you tap.
A fair way to decide
BNPL isn't a trick or a trap; it's a small loan with a friendly interface. The same question applies as any loan: would this payment fit your month even if something else went wrong? If yes, and you'd like it to count toward your credit, a reporting provider paid on time is genuinely useful. If you're using BNPL because the card is full and the month is already tight, that's the situation where stacking starts, and where it deserves the same caution you'd give any new debt.
Where Solid Credit fits
As BNPL loans start appearing on credit reports, they also start appearing wrong on credit reports: new reporting pipelines mean new errors, like loans marked late that weren't, or paid-off plans still showing balances. Solid's free tools read your reports and flag entries that don't look right, BNPL included, so a reporting glitch doesn't quietly cost you points.

Common questions
Does Affirm affect your credit score?
Yes. Affirm reports its loans, including Pay in 4, to Experian and TransUnion. On-time payments can help, missed payments can hurt.
Does Klarna or Afterpay report to credit bureaus?
Generally not in the U.S. as of mid-2026. But unpaid balances can still go to collections, which does affect your credit.
Does using BNPL require a hard credit check?
Usually not for pay-in-4 plans (soft check only). Longer-term BNPL financing may involve a hard inquiry; the provider must disclose which.
Can BNPL build my credit?
It can, if the provider reports and you pay on time, especially useful for thin credit files. Non-reporting providers build nothing.
Will the new FICO BNPL scores change my credit score?
Probably not much. FICO's testing showed most users moved about 10 points or less, and lender adoption of new models takes years.
