Does Affirm Affect Your Credit Score? The 2026 Answer

Affirm markets itself as the honest BNPL: no late fees, ever. That part is true. The part people miss: Affirm reports every plan to the credit bureaus. In 2026, that tradeoff is the whole story.

Zero late fees, for real

Affirm has never charged a late fee on any plan in its history. Miss a payment and you owe no fee. That is genuinely unique among major BNPL providers. But "no fee" is not "no consequence."

What Affirm reports

Since April 2025, Affirm reports all of its loans, including Pay in 4, to Experian, and since May 2025 to TransUnion. It does not report to Equifax. Missed payments are reported after 30 days past due and can remain on your report for up to 7 years. On-time payments build a positive tradeline, which can help a thin credit file.

The APR side

Affirm's Pay in 4 is always 0% APR. Its longer plans (3 to 60 months) run 0% to 36% APR as simple interest, never compounding. About 43% of Affirm loans carry 0% APR, per company disclosures. Check which product you accepted: the Pay in 4 you got at checkout and a 12-month plan are different animals.

So does Affirm help or hurt your score?

It depends on your behavior, which is the honest answer for every credit product. On-time payments on an Affirm plan add a positive tradeline. Late payments get reported. Opening many Affirm plans in a short window can look like several new accounts at once. And because Affirm reports while Klarna and Afterpay (Pay in 4) do not, the same shopping habit looks different on your file depending on which app you used.
