Buy now, pay later and your credit report: what Affirm, Klarna, and Afterpay actually do

For years, the honest answer to "does BNPL show up on my credit report?" was almost always no, regardless of provider. That stopped being one answer in 2025. Affirm now reports essentially everything, including four-payment Pay-in-4 plans, to two of the three major bureaus. Klarna and Afterpay have gone the other way and declined to send that same Pay-in-4 data to any bureau. And FICO built the first mainstream credit score designed to actually use BNPL data — but it only shows up for a specific loan application if the lender making that decision chooses to request it. Three companies, three different answers, all current as of the same year.

Why this gap exists in the first place

A Pay-in-4 loan — split a purchase into four payments, usually two weeks apart, usually with no interest and no hard credit pull — was built to feel more like a debit card than a loan. For most of its existence as a product category, it was also functionally invisible to the rest of the lending system: a given BNPL provider could see your payment history with them, but a mortgage lender, a car lender, or a credit card issuer evaluating you six months later generally could not, because that history was not being sent to Equifax, Experian, or TransUnion at all. The Consumer Financial Protection Bureau's own research into 2021-2022 BNPL usage found that 63% of borrowers took out more than one BNPL loan at the same time, often from more than one company — debt that was, and in large part still is, effectively invisible to any single lender looking at a credit file. That invisibility, not any one company's decision, is the backdrop for everything below.

Affirm: reporting nearly everything, to two of three bureaus, starting in 2025

Affirm expanded its credit-bureau reporting twice in quick succession in 2025. It began reporting all of its pay-over-time loan products — including Pay-in-4 plans, not just its longer-term interest-bearing loans — to Experian, covering loans issued from 1 April 2025 onward. It then did the same with TransUnion, covering loans issued from 1 May 2025 onward. Equifax is not part of either announcement, so Affirm activity has no equivalent visibility there.

The detail worth being precise about: reporting a loan and scoring a loan are not the same step. Affirm's own announcements were explicit that this data appearing on a credit file does not mean it is automatically factored into a person's traditional FICO or VantageScore score today — the loans become part of the visible record on file with Experian and TransUnion, but conventional scoring models built before this change do not yet weigh them the way they weigh a credit card or an auto loan. That is precisely the gap the next section's new scoring model was built to close.

Klarna and Afterpay: declining to send Pay-in-4 data, as of 2025

Klarna and Afterpay — the latter owned by Block — took the opposite position on the same question. Reporting in August 2025 confirmed both companies were declining to send their U.S. Pay-in-4 loan data to any of the three credit bureaus, a stance both attributed to the same underlying concern: that a bureau receiving incomplete or non-real-time BNPL data, plugged into scoring models never designed for a loan product with this shape, could penalize a customer who is actually paying reliably. Juan Hernandez, Block's head of credit and underwriting, put the company's reasoning this way: "Credit reporting, scoring and interpretation still largely operate under legacy frameworks."

This is specifically about Pay-in-4 — and it is a fast-moving picture. Both companies' reporting practices for other products (longer installment loans, and what happens once an account goes to collections) are not necessarily the same as their Pay-in-4 policy, and coverage of their current 2026 practices is inconsistent across sources. If you're relying on this for a specific decision — checking what a lender will actually see — the reliable move is to check the current terms directly with the provider or pull your own Experian, Equifax, and TransUnion files rather than assume any snapshot, including this one, is permanent.

FICO Score 10 BNPL: the first mainstream score built to use this data

FICO announced FICO® Score 10 BNPL and FICO® Score 10 T BNPL on 23 June 2025, describing them as the first credit scores from a major scoring provider built to incorporate BNPL loan data. The announcement followed a joint year-long study with Affirm comparing FICO Score outcomes for more than 500,000 consumers who had opened at least one Affirm BNPL loan against a benchmark population that had not. FICO said the research showed the effect on score predictiveness ranged from a modest improvement to no adverse impact, and that its model design specifically groups a consumer's separate BNPL loans together as one input rather than counting each one as a separate new account — intended to avoid penalizing someone simply for using Pay-in-4 the way it is designed to be used, in several small loans opened close together.

The scores became available to lenders in the fall of 2025, offered side by side with FICO's existing score versions at no additional fee. The detail that matters most for a consumer trying to figure out what actually applies to them: a lender has to choose to request the BNPL-aware version of the score. It is not a universal replacement for the standard FICO Score, and it does not retroactively apply to every credit decision — whether BNPL history factors into your score on any specific application still depends on which score version the lender in front of you decided to pull.

What this actually means if you use one of these products

If you use Affirm, your payment history — including Pay-in-4 — is now part of your Experian and TransUnion file if the loan was issued after the relevant 2025 date. It is visible on the file itself; whether it moves your score depends on whether a given lender is using a BNPL-aware scoring model at all.
If you use Klarna or Afterpay Pay-in-4, that specific loan data was not, as of the confirmed 2025 reporting, going to any bureau — meaning it is neither helping nor hurting your score by design, though a delinquent account sent to a third-party collector can still surface on your report through that collector, the same as any other unpaid debt.
A "good" BNPL score doesn't mean every lender sees it. Because pulling the BNPL-aware FICO score is a lender's choice, two lenders looking at the same applicant on the same day can be working from different information about that applicant's BNPL history.
The CFPB's multiple-concurrent-loan finding is still the bigger practical risk for something like a mortgage application: a pattern of several small BNPL loans spread across providers can add up to real monthly obligations that no single bureau pull captures completely, which is why several mortgage lenders now ask about BNPL use directly on an application rather than relying on a credit report to surface it.
