You bought a $180 pair of running shoes and split it into four $45 payments. Simple, interest-free, done. For most of the last decade, that transaction was a ghost in your financial life — it never appeared on your credit report, so it couldn't help your score and, unless things went badly wrong, it couldn't hurt it either. That invisibility is ending. FICO has introduced two new scoring models — FICO Score 10 BNPL and FICO Score 10 T BNPL — the first scores from a leading provider designed to pull Buy Now, Pay Later loans directly into the credit picture lenders see. Roughly half of U.S. adults have used one of these plans, and the behavior underneath them has gotten shakier: 47% of BNPL users say they paid late at least once in the past year. As those once-hidden loans start surfacing on credit files, the pay-in-four habit you never thought about is about to start talking to your score. Here's exactly how, and what to do about it.
The change: BNPL is stepping out of the shadows
FICO announced FICO Score 10 BNPL and FICO Score 10 T BNPL in June 2025 and began incorporating Buy Now, Pay Later data into scoring in the fall of that year. They are the first credit scores from a major scoring company built specifically to account for BNPL loans — how many plans you open, how often you use them, and whether you pay on time. Until now, most pay-in-four loans simply weren't reported to the national credit bureaus, which is why a missed BNPL payment could sting your wallet with a late fee but leave your FICO score untouched.
Adoption won't be instant. The most widely used model in the country is still FICO Score 8, which launched back in 2009, and lenders tend to move to new score versions slowly — often over years. So the change is a rolling tide, not a switch that flips overnight. But the direction is set: the installment plans that powered a roughly $560 billion U.S. market in 2026 are moving from invisible to on-the-record, and the newer models are designed to read them.
This sits alongside a broader modernization of credit scoring. The same generation of models — including the 'trended data' approach in FICO's 10 T line — looks at up to 24 months of behavior rather than a single snapshot, rewarding people who pay balances down over time and penalizing those whose debts creep upward. BNPL is one more stream of behavior feeding into that longer view.
Why the timing is risky for a lot of people
BNPL went mainstream fast, and the habits around it have gotten looser. About 49% of Americans have used a BNPL loan, and the share paying late is climbing: 47% of users report a late payment in the past year, up six points from the year before and 13 points over two years. Nearly one in five users — 19% — say they've simply lost track of what they owe.
The bigger hazard is 'loan stacking.' Because each plan is small and approvals are near-instant, it's easy to run several at once. Some 63% of users have held multiple BNPL loans simultaneously, 25% have juggled three or more, and 33% spread them across different providers — which makes the total impossible for any single system to see. When these loans were invisible to credit files, that fragmentation hid the true debt load. As reporting expands, the same stacking that was a budgeting problem becomes a scoring problem too.
And this isn't just discretionary splurging anymore. Groceries now account for about 25% of BNPL usage, up from 14% a year earlier, and nearly 60% of users say they've reached for a plan to buy something they couldn't otherwise afford. Financing everyday essentials in four installments is a stress signal — and it's exactly the kind of pattern newer scoring models are built to notice.
Which BNPL loans actually show up — and which still don't
Here's the catch that trips people up: FICO building a model that can read BNPL data doesn't mean every provider is feeding data into your file. Reporting is still a patchwork in 2026, and it varies by lender and by bureau.
- Affirm — began furnishing repayment data to Experian and TransUnion in 2025, so its pay-over-time loans are among the most likely to appear on your report.
- Klarna — has not been reporting standard pay-in-four repayment data to the three national bureaus, so most of its short-term plans have stayed off traditional files (for now).
- Afterpay — similarly has not been furnishing pay-in-four data to the national bureaus, meaning those loans have largely remained invisible to legacy scores.
- The moving target — reporting practices are shifting quickly as FICO's BNPL-aware models roll out. Assume that what's off your report today can be on it tomorrow, and treat every plan as if a lender will eventually see it.
How BNPL can help your score — or quietly drag it down
Reporting cuts both ways. Used carefully, a BNPL loan that reports on-time payments can add a small positive tick to your payment history — the single biggest factor in a FICO score. FICO's own testing suggested that consumers who manage these loans responsibly could see their scores hold steady or even improve under the new models.
The downside is just as real. A single missed BNPL payment that gets reported can behave like any other late payment — and payment history carries the most weight of any scoring factor, which is how a modest late installment can shave a meaningful chunk off your number. Opening several plans in a short window can also read as a burst of new-account activity, the kind of pattern that makes a score dip. In a credit environment where card APRs are hovering north of 22% and total card balances sit around $1.25 trillion, a lower score is expensive: it can mean pricier auto loans, steeper card rates, and a weaker hand when you apply for a mortgage.
5 moves to protect your score in the BNPL era
- Treat every plan like a real loan. It is one. Before you split a purchase, ask whether you'd put the same amount on a card and pay it in full next month. If the answer is no, that's your signal.
- Cap how many plans you run at once. Stacking three or four simultaneous plans is the fastest way to lose track — and, increasingly, to look overextended to a lender. One active plan at a time is a sane ceiling for most budgets.
- Automate the payments. With 19% of users admitting they lose track, autopay from an account you keep funded is the cheapest insurance against a reported late payment.
- Pull your credit reports and look for BNPL lines. You can check all three bureaus free at AnnualCreditReport.com. If a plan you paid off is still showing as open or delinquent, dispute it.
- Stop financing essentials. If groceries or gas are going on a payment plan, the problem isn't the checkout button — it's the budget behind it. Fix the cash-flow gap before it becomes a credit gap.
The bottom line
Before you tap 'pay in 4' on your next purchase, add up every BNPL plan you already have open — across all apps — and treat the combined balance as one loan you have to clear. Run that number through a loan calculator to see the real monthly commitment you're signing up for. If the total makes you wince, that's the plan talking to your budget before it ever talks to your credit score.
Buy Now, Pay Later was designed to feel weightless — no interest, no paperwork, no mark on your credit. That last part is what's changing. With FICO's BNPL-aware scores now in circulation and providers steadily expanding what they report, the four-payment habit is graduating into your permanent credit record, where on-time payments can help and slip-ups can cost you. The fix isn't to swear off BNPL; it's to treat each plan with the same respect you'd give any loan — one at a time, on autopay, and only for things you could actually afford. If you're carrying several plans right now, add them up and see the true monthly weight before you add another. Our [Personal Loan Calculator](/finance/personal-loan) lets you model that combined balance as a single loan — the payment, the payoff timeline, and the real cost of financing purchases in installments — so the decision happens in your budget, not on your credit report.
