For years, buy-now-pay-later purchases lived in a blind spot: you could carry several installment plans at once and none of it showed up on a credit report, for better or worse. That’s no longer uniformly true. Affirm, Klarna, and the credit bureaus have been moving pieces into place since 2024, and by late 2026 the honest answer to “does BNPL affect my credit score” is “it depends which provider you used and which bureau is asking” — not a clean yes or no.
What Affirm Reports, and Since When
Affirm has gone the furthest of the major providers. It furnishes its pay-over-time loans to Experian and TransUnion, and starting April 1, 2025, it expanded that reporting to cover all of its pay-over-time products, including the short-term Pay-in-4 plans that previously sat outside credit reporting entirely. That means an Affirm plan can now build payment history the way an installment loan does — and a missed payment can show up as a real derogatory mark, not a private matter between you and the merchant’s financing partner.
Where Klarna Actually Stands
Klarna’s position is the one most likely to be misstated, because the public record on it has shifted and different sources describe different snapshots in time. Klarna began furnishing certain data to TransUnion and Equifax in the U.S., and reporting through 2026 describes Klarna reporting transaction data — including Pay-in-4 — to those two bureaus specifically. Separately, some coverage has described Klarna declining to report Pay-in-4 data to bureaus at all, and other 2026 summaries claim full three-bureau reporting including Experian. Those accounts don’t fully agree with each other, which is itself the useful takeaway: don’t assume your Klarna plan is or isn’t on your report based on a general claim. Pull your own Experian, Equifax, and TransUnion files, or check Klarna’s current published disclosures directly, before you assume either outcome.
Afterpay, the other major Pay-in-4 provider, has been reported as holding off on U.S. bureau reporting for its short-term plans, though this space is moving quickly enough that any specific provider’s stance is worth re-checking rather than treated as fixed.
FICO Built Scores Specifically For This
The credit-scoring side moved in parallel. FICO announced FICO Score 10 BNPL and FICO Score 10 T BNPL in 2025, describing them as the first credit scores from a major scoring provider to incorporate buy-now-pay-later data directly, with availability tied to fall 2025 and rollout continuing as bureaus began furnishing BNPL data at meaningful scale into 2026. The design goal, per FICO’s own materials, is to reflect how people actually use short-term installment credit rather than treating it as invisible or lumping it in with revolving card debt.
Adoption on the lender side has been gradual rather than immediate. FICO Score 10T — the trended-data variant lenders have moved toward fastest — had passed 70 mortgage lenders signed on by mid-2026, but that’s the base trended score, and BNPL-specific adoption is a step behind that. In practice, a specific loan application in 2026 may or may not be evaluated using a BNPL-aware FICO model; it depends on which score version that particular lender has adopted.
What This Means If You Use BNPL Regularly
The direction of travel is clear even where the details vary by provider: BNPL activity is becoming visible to at least some bureaus for at least some providers, and that visibility cuts both ways. On-time payments across multiple concurrent plans can now function like a positive track record instead of disappearing into nothing. Missed payments can now function like a missed installment loan payment, potentially with the same kind of score impact — some reporting on FICO and Affirm’s joint findings describes typical score movement in the range of what you’d see from opening a new account, with larger swings for people juggling five or more concurrent BNPL plans depending on repayment behavior.
The practical shift is that “it’s just BNPL, it doesn’t really count” stopped being a safe assumption sometime between 2024 and 2026. Treat a BNPL plan with the same payment discipline you’d apply to any other installment debt, because for a growing share of providers and bureaus, that’s exactly what it now is on paper.
Frequently Asked Questions
Does using Affirm or Klarna hurt my credit score?
Not by itself. On-time payments on a reporting provider’s plan can build positive payment history, similar to an installment loan. The risk is on the downside: if a provider furnishes your account and you miss a payment, that can now show up as a real derogatory mark rather than staying invisible, which wasn’t always true before 2024–2025.
Does Klarna report to all three credit bureaus?
The public record is mixed. Some sources describe Klarna furnishing data to TransUnion and Equifax but not Experian; others describe broader adoption. Check your own credit reports directly or Klarna’s current disclosures rather than relying on a general claim, since accounts of Klarna’s reporting status don’t fully agree.
What is FICO Score 10 BNPL and does it apply to my loan application?
It’s a credit-scoring model FICO introduced starting fall 2025 that factors in buy-now-pay-later data specifically. Whether it applies to you depends on which score version the lender evaluating your application has adopted — adoption has been gradual, with the related FICO Score 10T model reaching more than 70 mortgage lenders by mid-2026.
Should I stop using BNPL because it now affects my credit?
Not necessarily — the same logic that applies to any installment debt applies here: it’s manageable if you make payments on time and track how many concurrent plans you’re carrying. The change is that the consequences of not doing so are now more likely to follow you onto an actual credit report.
BNPL reporting is still a patchwork rather than a settled standard, and providers can and do change their bureau relationships. The one reliable move is checking your own reports periodically rather than assuming last year’s rule about “BNPL doesn’t count” still holds.
