Affirm does not charge late fees. That applies to every product the company offers, including Pay in 4 and longer monthly installment loans, and the zero-fee promise is written into Affirm’s terms of service.1Affirm. Terms of Service Missing a payment still has real consequences, though: interest keeps running on any loan that carries an APR, the late payment can be reported to the credit bureaus, and an unpaid balance can eventually be sent to collections.2Affirm Help Center. Late Payments
What Missing a Payment Still Costs You
You will not see a flat $25 or $40 penalty added to your balance the way a traditional credit card would charge one. The total cost shown at checkout does not go up because of a missed due date.1Affirm. Terms of Service
Two costs can still hit you. If Affirm tries to auto-debit your bank account and the funds are not there, your own bank may charge a non-sufficient funds or overdraft fee. Affirm has no control over that charge. And on any loan that carries interest, the missed payment leaves the principal higher for longer, so daily interest keeps accruing on a larger balance. That is not a penalty. It is simply the cost of borrowing the money for more time.
Affirm loans carry a fixed APR between 0% and 36%, set at checkout. Pay in 4 plans always carry 0% APR.3Affirm Holdings, Inc. Affirm Updates Underwriting With Enhanced Signals to Better Reflect If your plan is 0%, a late payment does not generate any extra interest. It can still hurt you in the ways below.
What a Late Payment Does to Your Credit
Affirm changed its reporting practices in 2025, and anyone using the platform now should assume everything shows up on their credit file. Starting April 1, 2025, Affirm reports all payment activity on every pay-over-time product, including Pay in 4, to Experian.4Affirm Holdings, Inc. Affirm Expands Credit Reporting With Experian to Include All Pay-Over-Time Products Starting May 1, 2025, the same reporting applies to TransUnion.5Affirm Holdings, Inc.

Payments more than 30 days past due may be reported as late.2Affirm Help Center. Late Payments A single late-payment notation can drop your score by dozens of points and stays on your credit report for up to seven years, which affects future mortgages, auto loans, and other credit well beyond Affirm.
What Happens If You Keep Missing Payments
Affirm follows a gradual escalation if you fall behind and do not catch up.
- Right after a missed payment, Affirm will try to contact you and you can log in to reschedule. No late fee is added.2Affirm Help Center. Late Payments
- Once you cross 30 days past due, the late payment can be reported to Experian and TransUnion.
- At 120 days past due, Affirm may charge off the loan, meaning it writes the balance off as a loss. From that point, the debt can be sent to an outside collection agency at any time.7Affirm Help Center. Collections and Charged-Off Payment Plans
- After the account goes to collections, you can no longer pay Affirm directly. You have to work with the collection agency.7Affirm Help Center. Collections and Charged-Off Payment Plans
A charged-off account is one of the most damaging entries on a credit report and can remain visible to lenders for seven years. If Affirm or a collector later settles or cancels the remaining balance, any forgiven amount of $600 or more triggers an IRS Form 1099-C, and the canceled debt counts as taxable income on your federal return.8Internal Revenue Service.

How Late Payments Affect Future Affirm Purchases
Even before anything reaches collections, late payments hit you inside Affirm’s own system. The company runs an automated risk check on every purchase request, and a history of missed or late payments can shrink your internal spending limit or lead to outright denial.2Affirm Help Center. Late Payments
While a balance is overdue, Affirm may block you from opening new plans entirely.1Affirm. Terms of Service Paying off the overdue balance does not automatically restore your purchasing power. Affirm’s terms do not publish a specific timeline or set of criteria. The decision is made case by case by the company’s underwriting, and consistent on-time payments over time are the most reliable way to rebuild access.
If the Payment Is Late Because Something Went Wrong With the Purchase
If the reason you are considering stopping payment is a problem with what you bought — the item never arrived, or it was significantly different from what was described — open a dispute with Affirm rather than simply missing the due date. As of July 2024, you are not required to keep paying the disputed amount while the investigation is open, and Affirm withholds the disputed funds until the matter is resolved.9Affirm US (English) Help Center. Dispute Resolution Policy Going through the dispute process protects you from the credit and collections consequences of a plain missed payment.
