Buy Now, Pay Later Now Shows Up on Your Credit Score. Here Is How to Check.

For years, the four little payments you split at checkout were invisible to your credit score. They neither helped it nor hurt it. As far as FICO was concerned, they did not exist. That is over. Starting in 2025, buy now, pay later loans began landing on credit reports and, for the first time, inside the score itself.

Call it the silent tradeline. A tradeline is just one line on your credit report: a single account with its balance and its payment history. Your Affirm or Klarna plans used to leave no such line behind. Now some of them do, quietly, without you signing anything new. The question that actually touches your wallet is narrow. Which of your apps now show up, and is that new line lifting your score or weighing it down?

You can find the answer yourself in about ten minutes, for free, and hand the tedious part to an AI. Here is what changed, which providers report where, and how to read your own file today.

What actually changed in 2025

The turning point was June 23, 2025, when FICO unveiled two scoring models built to read BNPL data. FICO Score 10 BNPL and FICO Score 10 T BNPL are the first scores from a major scoring company to incorporate buy now, pay later loans, and they began rolling out to lenders in the fall of 2025, according to FICO's announcement. Lenders can now pull one score that counts your BNPL loans and one that ignores them, and decide which to use.

The data started moving even before the scores did. Affirm began reporting all of its pay-over-time loans, including its popular Pay in 4, to Experian on April 1, 2025, and to TransUnion on May 1, 2025, per Bankrate and Payments Dive. It does not report to Equifax. In a November 2025 statement, Affirm framed the move as giving responsible borrowers credit for paying on time. Either way, the practical effect is the same: for tens of millions of people, a category of borrowing that never touched their file suddenly does.

And it is tens of millions. About 91.5 million Americans used BNPL in 2025, up roughly 6% from the year before, and more than half of U.S. adults have used it at least once, according to industry estimates and the CFPB's market reporting. A form of credit that big does not stay off the credit system forever.

Which of your apps show up, and which stay hidden

Not every BNPL app reports, and the ones that do report do not all report the same thing. This is the part most coverage glosses over, and it is the part that decides whether any of this touches you. Here is where the major providers stood as of mid-2026.

Read that table with one caveat that cuts across every row. Even a provider that does not report your on-time payments can still hurt you if you default badly enough that the debt gets sold to a collections agency, because collections accounts land on your report no matter who they came from. So the "No" rows are not a free pass. They mean the upside of paying on time is invisible while the downside of a real default is not.

Could this help your score, or hurt it?

For someone who pays on time, BNPL on your report is more likely to help than hurt, and that is the genuinely counterintuitive part of this story. The headline reads like a threat. The data reads gentler. In FICO's own research using Affirm accounts, consumers who had five or more Affirm loans generally saw their scores hold steady or rise under the new BNPL-aware model. Payment history is the heaviest single ingredient in a FICO score, so a run of on-time payments that finally gets reported is positive history you were not getting credit for before.

The risk is real too, and it is worth ranking rather than lumping together. The biggest one is that a missed payment is no longer a private slip. On an app that reports, a 30-day late that used to vanish now sits on your file where every future lender can see it. Second is stacking: FICO's BNPL models group your multiple BNPL loans together, and carrying several open plans at once can read as leaning hard on short-term credit. Third, and mildest, is account age, since a pile of brand-new lines can nudge down the average age of your accounts. In one sentence: this rewards discipline and punishes juggling.

The reason stacking is a growing worry is that the average person is spending more through these apps every year, so there is simply more of it to juggle.

Check your own credit file today

You do not have to guess whether your BNPL is on there. Pull your report and look. The whole check takes about ten minutes and costs nothing.

Start at AnnualCreditReport.com, which is the only site federally authorized to give you the reports for free, and where all three bureaus are now available every week (the weekly access became permanent in 2023, per the FTC). Focus on your Experian and TransUnion reports, since that is where Affirm and Klarna financing show up; your Equifax report will not list BNPL. Then read the account list like a stranger would and look for names like Affirm or Klarna, checking the balance and the payment status on each. One thing the free report does not include is your actual score, so if you want the number, pull it from a card issuer or lender that shows it.

Once you have the account rows in front of you, the sorting and the interpretation are exactly the kind of tedious read AI does well, as long as you give it your real details and tell it not to invent the rest. Paste this into ChatGPT or Claude and swap in your own numbers inside the brackets.

You are helping me understand how my buy now, pay later
(BNPL) accounts look on my credit report.
Use only the details I give you. Do not guess missing data.

My BNPL accounts (from my credit report):
- [Affirm] balance [$420], opened [Mar 2026], status [on time]
- [Affirm] balance [$180], opened [May 2026], status [on time]
- [Klarna financing] balance [$600], opened [Jan 2026],
  status [30 days late once]

Do the following:
1. Count my open BNPL tradelines and total BNPL balance.
2. Flag any late marks and which account they sit on.
3. Explain in plain terms how a BNPL-aware score (like FICO
   Score 10 BNPL) might read this: what likely helps, what
   likely hurts.
4. Give the one action that would most improve how this looks.

Say clearly that exact scoring is proprietary and that you
are giving general reasoning, not my real score.

Feed it those example rows and the reply looks about like this.

The one thing to watch is that if you ask an AI for a specific score, it will often hand you a confident three-digit number anyway. It cannot compute your real FICO, and it does not have the rest of your file. Keep it to the reasoning, and get the actual number from a lender.

So should you stop using pay-in-four?

My read is no, and not because the reporting is harmless. I lean the other way on the reporting itself. For someone who clears their plans on time, a reported BNPL line is a small, free way to build positive payment history, and FICO's test data pointing to stable-or-higher scores for frequent Affirm users backs that up. The thing that actually gets people into trouble was never the credit reporting. It is the stacking, the fourth and fifth open plan taken out because each one felt too small to count.

Here is the case where I would pull back. If you already run three or four plans at a time and miss a due date now and then, the new visibility just converted a private stumble into a public record, and you are exactly the person the change can hurt. For everyone else, the fix is not to swear off pay-in-four. It is to treat every plan as a real loan that a lender can now see, and to never let the number of open plans climb past what you could clear this month if you had to. Run the check, pay closest attention to any late marks sitting on your file, and decide from what is actually there rather than from the headline.

FAQ

Does buy now, pay later affect your credit score in 2026?

It can now, which is the new part. FICO's June 2025 models, Score 10 BNPL and Score 10 T BNPL, fold buy now, pay later into the score for the first time, and some providers now send your activity to the bureaus so it appears on your report. Whether it helps or hurts turns on how you pay: on-time payments can add positive history, while a missed payment that used to be invisible is now something lenders can see.

Which BNPL apps report to credit bureaus?

As of mid-2026, Affirm reports all pay-over-time loans, including Pay in 4, to Experian and TransUnion but not Equifax. Klarna does not report standard Pay in 4 on-time payments, though it reports its 6-to-36-month financing plans to Experian and TransUnion. Afterpay and PayPal Pay in 4 do not report on-time payments at all. A serious default sent to collections can still appear on your report from any of them.

Can buy now, pay later help build my credit?

On the apps that report, sometimes yes. FICO research using Affirm data found people with five or more Affirm loans generally saw scores hold or rise under the BNPL-aware model, since on-time payments add to payment history, the heaviest scoring factor. It only builds credit if the provider actually reports on-time activity, which most Pay in 4 plans still do not, and if you pay on time.

How do I check if my BNPL loans are on my credit report?

Pull your free report at AnnualCreditReport.com, the only federally authorized site, where all three bureaus are free every week. Check Experian and TransUnion, since that is where Affirm and Klarna financing land, and scan the account list for names like Affirm or Klarna along with the balance and status. The report shows accounts but not your score, so pull the score separately from a lender or card issuer.
