For years, those four easy payments at checkout lived in a credit blind spot. Split a $200 purchase with Klarna or Affirm, and your mortgage lender simply never saw it. That era is ending — and if you use buy-now-pay-later at all, your habits just started counting.
What changed
FICO — whose scores sit behind most major U.S. lending decisions — built two new scoring models, FICO Score 10 BNPL and 10 T BNPL, the first to fold pay-later loans into creditworthiness. They began rolling out in fall 2025, and through 2026 lenders have been putting them to work.
The models look at what you'd expect, per FICO and reporting at NPR: how many BNPL accounts you've opened, how often you lean on them, and whether you pay on time. Pay-later stops being invisible money and starts being credit history.
Why lenders wanted this
The old arrangement had a hole in it, and NPR's explanation is the cleanest: because BNPL loans mostly weren't reported to credit bureaus, card issuers couldn't see that debt when deciding your limit. A person juggling six pay-in-four plans looked identical to someone carrying none — so lenders could unknowingly extend more credit than a borrower could handle. The industry took to calling it phantom debt. The new scores switch the lights on.
Will your score tank?
Probably not — and this is worth internalizing before the panic sets in. FICO ran a yearlong study with data from Affirm and found that for more than 85% of consumers, adding BNPL data moved scores within about 10 points, up or down, as NPR reported.
The direction is what you control. Empower's read: pay every installment on time and the new models may actually help you — useful if your credit file is thin and BNPL is most of your borrowing track record. Miss payments or stack plans across five apps, and the data works against you, a risk NMI's analysis flags for heavy users especially.
How to use BNPL now that it counts
A few adjustments cover most of it. Treat every pay-later plan as what it now officially is: a loan on your record, not a checkout button. Put installments on autopay — a missed $25 payment can now echo beyond a late fee. Keep simultaneous plans to a number you can recite from memory; opening many accounts quickly is exactly the pattern the models watch. And if you're rebuilding credit, on-time BNPL history has become a modest tool rather than a dead end.
One more: glance at your credit reports occasionally. Adoption is uneven — different lenders will factor BNPL differently for a while — so it pays to know what's showing up under your name.
The bottom line
BNPL didn't get more dangerous this year. It got more honest. The four-payment split now behaves like the credit product it always was — which is bad news only for the version of you that treated it like free money.
