You've probably seen Affirm at checkout—that tempting option to split your purchase into smaller payments with no interest. But before you click, you're wondering: will this hurt my credit score? The answer depends on how you use it. Affirm can affect your credit differently depending on which payment plan you choose. Understanding the details helps you make smarter borrowing decisions. For a step-by-step walkthrough on exactly when Affirm shows up on your credit report and when it doesn't, see our deep dive on whether Affirm builds credit.
When Affirm Does a Hard Pull vs. Soft Pull
When you apply for an Affirm loan, the company may check your credit. There are two types of checks: soft and hard pulls. A soft pull doesn't affect your credit score at all—Affirm uses this to pre-qualify you and show you available offers.
However, if you proceed with an application, Affirm typically does a hard inquiry for longer-term installment plans. A hard pull temporarily lowers your credit score by a few points (usually 5-10 points) and stays on your report for about 12 months. Learn more about how long a hard inquiry stays on your credit report. Pay-in-4 plans typically use soft pulls only.
When Affirm Reports to Credit Bureaus
As of 2025, Affirm reports all of its loan products — including Pay in 4 — to Experian and TransUnion. This is a significant change from earlier years when only longer-term plans were reported.
What this means for you:
- Pay in 4 plans: Now reported to Experian and TransUnion as of April/May 2025.
- Monthly installment plans (3–36 months): Reported to Experian and TransUnion.
- Equifax: Affirm does not currently report to Equifax.
For a focused breakdown of what credit bureau Affirm uses when it pulls your file at application versus where each loan ends up reporting, our dedicated guide walks through both sides of the equation.
This is good news if you pay on time — every Affirm payment adds positive history to your Experian and TransUnion credit files. But it also means that missed payments on any Affirm plan, including Pay in 4, can now damage your credit score on those two bureaus. Understanding how credit scores are calculated helps you see why this matters.
Affirm vs. Other Buy Now, Pay Later Services
Affirm isn't the only BNPL option out there. Klarna, Afterpay, and PayPal Pay in 4 all work similarly as payment methods. If you're curious about other services, check whether Afterpay builds credit or see our roundup of the best BNPL apps that build credit.
What makes Affirm stand out from most BNPL competitors: it now reports all plans to two of the three major bureaus (Experian and TransUnion). Many other BNPL services still don't report, or only report to one bureau with an opt-in requirement. Affirm's reporting is automatic and covers all its products.
Sezzle: The Closest BNPL Comparison for Credit Building
The one BNPL competitor that comes closest to Affirm on credit building is Sezzle. Sezzle's standard product is interest-free Pay in 4, and it offers an opt-in feature called Sezzle Up that reports on-time payments to TransUnion and Experian — the same two-of-three bureau coverage as Affirm.
How Sezzle stacks up against Affirm for credit:
- Reporting bureaus: Sezzle Up reports to TransUnion and Experian. Affirm reports to the same two bureaus. Neither reports to Equifax.
- Opt-in vs. automatic: Sezzle Up requires you to enroll. Affirm reporting is automatic on all plans.
- Credit check at signup: Sezzle uses a soft check only. Affirm's Pay in 4 also uses a soft check, but longer-term Affirm loans pull a hard inquiry.
- Loan size: Sezzle's initial Spending Power is typically $50 to $150, focused on smaller everyday purchases. Affirm scales up to $1,000+ for longer-term financing.
- Interest: Sezzle's Pay in 4 is interest-free. Affirm's Pay in 4 is also interest-free, but its longer-term plans can carry APRs of 0–36%.
If you want a smaller, interest-free BNPL with an explicit credit-building feature, Sezzle is the cleanest fit. If you need bigger-ticket financing with automatic reporting, Affirm wins. See our Sezzle review and the deeper does Sezzle build credit explainer for more detail.

How to Use Affirm Without Hurting Your Credit
Want to use Affirm safely? Treat it like any other loan: pay on time, every time. Since Affirm now reports all plans to Experian and TransUnion, every payment — including Pay in 4 — builds your payment history on those two bureaus. A missed payment will now damage your credit, regardless of which plan you chose.
Also, avoid applying for multiple Affirm loans in a short period just to take advantage of offers. Each longer-term application triggers a hard pull, and too many inquiries in a short time can signal risk to lenders. Only use Affirm for purchases you can actually afford.
If you want to actively build credit across all three bureaus (including Equifax), a secured credit card or credit builder loan is a more complete tool. The Self Visa® Credit Card reports to all three bureaus and has high approval rates. The Kikoff Credit Account requires no credit check and no hard inquiry.

Using Affirm responsibly is now a more meaningful credit-building tool than it used to be. With all plans reporting to Experian and TransUnion, consistent on-time payments add real positive history to your credit file. Just keep in mind that it doesn't cover Equifax, and the same discipline applies: only spend what you can pay back, and treat every Affirm payment as a credit event — because it now is.
Frequently Asked Questions
Does Affirm do a hard credit check every time?
No. Affirm does a soft pull to pre-qualify you and show available offers. A hard inquiry only happens if you proceed with certain longer-term loan types. Pay-in-4 plans typically use soft pulls only.
Will using Affirm help me build credit?
Yes — as of 2025, Affirm reports all of its products (including Pay in 4) to Experian and TransUnion. Every on-time payment builds positive payment history on those two bureaus. Note that Affirm does not report to Equifax, so it won't help your credit with all three bureaus.
What happens if I miss an Affirm payment?
For any Affirm plan — including Pay in 4 — a missed payment can now lower your credit score on Experian and TransUnion. Affirm may also charge late fees and could send delinquent accounts to collections. Take all Affirm payments seriously, regardless of the plan length.
Is Affirm better than a credit card for building credit?
Not quite. A credit card — especially a secured credit card — is a more complete credit-building tool because it reports to all three bureaus (including Equifax) every month. Affirm now covers Experian and TransUnion, which is meaningful, but not a full three-bureau solution.
