Yes, Affirm can affect your credit score. As of 2025, Affirm reports every pay-over-time loan it issues — including short-term Pay in 4 plans — to the credit bureaus, so on-time payments can build your credit and missed payments can damage it. How much either direction moves your score depends on the rest of your credit profile.
Soft Pull vs. Hard Pull When You Apply
Checking your purchasing power or creating an Affirm account triggers only a soft credit inquiry. Soft inquiries are invisible to other lenders and do not affect your score.1Affirm Help Center. Affirm Credit Reporting Policy
If you accept certain financing terms, Affirm may then run a hard inquiry. A hard inquiry appears on your credit report, stays for up to two years, and typically lowers a FICO score by fewer than five points. Hard inquiries sit in the “new credit” category, which is 10% of your FICO score.2myFICO. What’s in Your FICO Scores
Which Affirm Loans Get Reported, and to Which Bureaus
Affirm’s reporting policy changed in 2025. Before that, only longer-term installment loans with interest were reported, and Pay in 4 plans were excluded. Starting April 1, 2025, Affirm began reporting all pay-over-time products issued from that date forward, Pay in 4 included.3Affirm Holdings, Inc.

Loans issued on or after April 1, 2025, are reported to Experian. Loans issued on or after May 1, 2025, are also reported to TransUnion. Affirm does not report to Equifax.4Affirm Help Center. Understanding Credit Reporting Because the three bureaus don’t hold identical data, the impact of an Affirm account on your score can vary depending on which report a future lender checks.
How On-Time Payments Can Help
Payment history is the biggest factor in a FICO score at 35%.2myFICO. What’s in Your FICO Scores Every on-time Affirm payment adds a positive entry to your file. Across a multi-month loan, that builds a documented pattern of reliability.
The effect is largest if you have a thin credit file — few accounts or a short history. An installment loan with clean payments gives scoring models more to work with, and over time that can help you qualify for better rates on other financing.
How Late Payments and Defaults Can Hurt
Affirm does not charge late fees on any of its products.5Affirm Help Center. Support During Difficult Times The credit consequences are a different matter. Once a payment is more than 30 days past due, Affirm may report the delinquency to the credit bureaus.6Affirm Help Center. Late Payments A single reported late payment can produce a noticeable drop, because payment history carries so much weight.
A reported late payment can stay on your credit report for up to seven years from the date the delinquency began.7Consumer Financial Protection Bureau. How Long Does Information Stay on My Credit Report The same limit applies to charge-offs and collection accounts.8Office of the Law Revision Counsel. 15 U.S. Code 1681c – Requirements Relating to Information Contained in Consumer Reports
If you stop paying entirely, Affirm may charge off the loan after it has been 120 days past due. A charged-off account can be sent to a third-party collection agency at any time, and from that point you deal with the collector rather than Affirm.9Affirm Help Center. Collections and Charged-Off Payment Plans A charge-off and a collection can appear on your report as two separate negative marks at once.
Credit Mix, Account Age, and Balances
Payments aren’t the only way an Affirm loan touches your score. It also interacts with three other pieces of your credit profile.
Credit Mix
Credit mix is 10% of a FICO score and reflects the variety of accounts you manage.2myFICO. What’s in Your FICO Scores An Affirm installment loan adds diversity to a file made up mostly of credit cards. You don’t need one of every type of account to score well, but a reasonable mix generally helps.
Length of Credit History
Age of accounts is 15% of a FICO score, and the model looks at the oldest account, the newest account, and the average across all of them.2myFICO. What’s in Your FICO Scores Opening a new Affirm loan drops your average account age and can cause a small, temporary dip. The fewer accounts you have overall, the more each new one moves that average.
Amounts Owed
Amounts owed is 30% of a FICO score. Revolving balances drive most of that number, but installment balances still play a part. A large balance relative to the original loan works against you, and paying it down over time helps. If you use an Affirm loan to pay off a credit card, the shift from revolving debt to installment debt can improve your credit utilization ratio.
Affirm Loans and a Future Mortgage Application
Active Affirm loans can affect a mortgage approval. Lenders calculate your debt-to-income ratio by adding your recurring monthly obligations and comparing the total to your gross income. Under Fannie Mae’s guidelines, any installment debt with more than ten monthly payments remaining must be counted toward that ratio. Installment debts with fewer payments left can still be counted if they significantly affect your ability to meet obligations.10Fannie Mae. Monthly Debt Obligations
Since Affirm now reports every pay-over-time product, even a short Pay in 4 plan can appear on the report a mortgage lender pulls. Several active plans stacked together can push your debt-to-income ratio past what a lender will accept. Paying off Affirm balances and avoiding new ones in the months before you apply keeps that ratio cleaner.
Fixing an Affirm Error on Your Credit Report
If Affirm reported something you believe is wrong, you have two ways to dispute it. The fastest is usually through the credit bureau itself — Experian or TransUnion — using its online dispute portal. You can also file a written dispute directly with Affirm.11Affirm Help Center. Credit Reporting Disputes
Include your name and loan number as they appear on the report, the specific information you believe is inaccurate, why it is wrong, and any documents that support you. If the account was opened without your permission, include an identity theft affidavit or report.
A credit bureau generally has 30 days from receipt of your dispute to investigate and respond.12Office of the Law Revision Counsel. 15 U.S. Code 1681i – Procedure in Case of Disputed Accuracy The bureau must send you the results in writing, and if the investigation changes anything, you are entitled to a free copy of the updated report.13Federal Trade Commission.
