Key takeaways
- Pay-in-4 plans usually charge 0% interest, but late fees can turn a cheap purchase into an expensive one: two $8 late fees on a $400 order work out to an effective APR of about 67%.
- The CFPB’s 2024 rule treating BNPL lenders like credit card issuers was withdrawn on May 12, 2025, so federal dispute protections for pay-in-4 loans are weaker than for credit cards.
- FICO launched FICO Score 10 BNPL and 10 T BNPL in 2025, and Affirm began reporting loans to Experian in April 2025, but most lenders still use older scores that don’t count BNPL.
- New York passed the first state BNPL licensing law in May 2025; its rules were still being finalized in late 2026, with a proposed $8 cap on late fees.
Buy now, pay later (BNPL) lets you split a purchase into smaller payments, most often four interest-free installments every two weeks. It can be a cheap way to spread out a planned purchase, but late fees, overlapping plans and weaker legal protections than credit cards can make it costly if you aren’t careful.
Rules for BNPL changed a lot in 2025 and 2026. Federal regulators stepped back, states like New York stepped in, and credit-scoring companies started building BNPL data into new scores. Here’s how BNPL works now, what it really costs and how to protect yourself.
How buy now, pay later works
At checkout, online or in a store, you choose a BNPL option and get a quick approval decision, usually with a soft credit check. There are two main types:
- Pay in 4. You pay 25% up front and the rest in three payments every two weeks. These plans usually carry no interest. They’re typically used for purchases of a few hundred dollars.
- Monthly installment loans. For bigger purchases, BNPL lenders offer loans of 6 to 36 months or longer. These can be 0% promotional offers, but many charge interest of up to about 36% APR, depending on your credit.
Payments are usually pulled automatically from a debit card, bank account or credit card. If a payment fails, you may owe a late fee, and some lenders pause your account until you catch up.
BNPL fees and costs
| Feature | Pay in 4 | Monthly BNPL loan | Credit card |
|---|---|---|---|
| Typical interest | 0% | 0% promo up to about 36% APR | Often 20%+ APR if you carry a balance |
| Late fees | Common; vary by lender and state | Some lenders charge none; others do | Yes, limited by federal safe-harbor amounts |
| Credit check | Usually soft | Soft or hard | Hard |
| Federal Truth in Lending disclosures | Often not required (no finance charge, four or fewer payments) | Yes, if interest is charged or more than four payments | Yes |
| Dispute rights for unauthorized charges and billing errors | Lender policy (plus state law where it applies) | Varies | Strong federal protections |
| Builds credit history | Sometimes; reporting is uneven | Often reported | Yes |
Worked example: what late fees really cost
Say you buy a $400 jacket with a pay-in-4 plan. You pay $100 at checkout and owe three more $100 payments over six weeks. Your debit card is short twice, and the lender charges an $8 late fee each time.
- Total paid: $400 + $16 in fees = $416.
- You borrowed $300 for about six weeks, with an average balance of about $200.
- Treated as interest, $16 on that loan works out to an effective APR of roughly 67%.
Now compare a larger monthly loan. A $1,200 laptop financed for 12 months at 29.99% APR costs $116.98 a month, or $203.74 in interest. At a 0% promotional rate, the same purchase costs $100 a month and nothing extra. The plan you’re offered matters far more than the brand name at checkout. You can test your own numbers with our loan calculator or credit card interest calculator.
Tip: Link BNPL plans to a debit card or bank account only if you keep a cushion in it. Overdraft and returned-payment fees from your bank can stack on top of the BNPL late fee.
Does BNPL affect your credit score?
It can, and that is changing. Historically, most pay-in-4 loans weren’t reported to the credit bureaus, so on-time payments didn’t help you and missed payments often didn’t show up unless the debt went to collections.
- Reporting is growing. Affirm began reporting customer loans to Experian on April 1, 2025. Some lenders report longer monthly loans but not short pay-in-4 plans, so reporting is still uneven across companies and bureaus.
- New scores count it. In June 2025, FICO introduced FICO Score 10 BNPL and FICO Score 10 T BNPL, which factor in BNPL loan data. Lenders choose whether to use them.
- Most lenders haven’t switched. Many lenders still rely on older FICO versions that don’t use BNPL data, and conforming mortgages still use Classic FICO. So for now, BNPL rarely moves the score most lenders see, but that may change.
- Collections always hurt. If you stop paying and a debt goes to collections, it can damage your credit no matter which score is used.
Mortgage and auto lenders may also ask about BNPL debts or see them on bank statements when they review your budget. Our guide to improving your credit score covers what matters most.
BNPL rules in 2026: what protects you
Federal rules pulled back
In May 2024, the CFPB issued an interpretive rule saying BNPL lenders are card issuers under the Truth in Lending Act. That would have given pay-in-4 users credit-card-style rights, such as disputing a charge and getting a refund when you return an item. A fintech trade group sued, and the CFPB withdrew the rule on May 12, 2025, along with other guidance. It has not reissued it.
That leaves a gap. Federal Truth in Lending rules generally apply to credit with a finance charge or more than four installments. A typical interest-free pay-in-4 plan falls outside that, so your rights depend largely on the lender’s own policies and your state’s laws. Federal laws such as the Fair Credit Reporting Act and debt collection rules still apply.
New York’s BNPL law
New York enacted the first state law aimed specifically at BNPL in May 2025 as part of its budget. Key points:
- BNPL lenders serving New Yorkers must get a license from the state Department of Financial Services (DFS).
- Lenders must offer dispute and unauthorized-charge protections modeled on federal credit card rules.
- DFS sets limits on fees and interest and requires underwriting to check that borrowers can repay.
The law takes effect 180 days after DFS finalizes its regulations. DFS released a draft in February 2026 and a formal proposed rule on July 15, 2026, with comments due September 14. The proposal would cap late fees at $8 unless DFS approves a higher cost-based fee, bar total fees from exceeding the amount financed and ban prepayment fees. Check the final version before relying on these limits.
Other states
Some states regulate BNPL lenders through existing consumer lending laws. California, for example, licenses many BNPL providers under its California Financing Law. With less federal oversight, more states may follow. If you have a problem, you can complain to your state’s financial regulator or attorney general, and you can still file with the CFPB.
Smart ways to use BNPL
- Use it for planned purchases, not impulse buys. If you wouldn’t buy it with cash today, pause. A no-buy challenge can help reset spending habits.
- Limit yourself to one plan at a time. Overlapping plans are the main way people lose track of payments.
- Put every due date on your calendar and build payments into your monthly budget.
- Read the late-fee and return policy before you agree. Ask how returns are refunded and whether payments pause during a dispute.
- Avoid paying BNPL with a credit card you don’t pay off in full. You could end up paying credit card interest on a “0%” loan.
- Compare the APR on monthly plans. A personal loan or a 0% intro APR card may cost less. See personal loan vs. credit card.
- Keep receipts and screenshots of your plan terms in case you need to dispute a charge.
Tip: Already juggling several plans? List each balance and due date, stop opening new ones, and pay off the plans with fees or interest first. Our guide to prioritizing debt repayment walks through the steps.
What to do if you can’t pay
Contact the lender before the payment date. Many will move a due date or set up a hardship plan. If you miss payments, expect late fees and a paused account first; long-overdue debts can be sent to collections and reported to credit bureaus. If a collector contacts you, you have rights under the Fair Debt Collection Practices Act. Our guide on what happens if you stop paying a loan explains the timeline.

Frequently asked questions
Is buy now, pay later a good idea?
It can be for a planned purchase you can afford, paid on time with a 0% plan. It’s a poor choice for impulse buys, everyday groceries you can’t cover, or monthly plans with high interest.
Can I dispute a BNPL charge like a credit card charge?
Not with the same federal guarantees. Since the CFPB withdrew its 2024 rule, pay-in-4 dispute rights depend mostly on the lender’s policy and state law. Contact the merchant and lender quickly and keep records.
Does paying BNPL on time build credit?
Sometimes. It helps only if the lender reports to a bureau and the lender checking your credit uses a score that counts BNPL data, such as FICO Score 10 BNPL. Many lenders don’t yet.
What happens if I miss a BNPL payment?
You’ll typically pay a late fee and may be blocked from new purchases. Unpaid balances can eventually go to collections, which can hurt your credit.
Are BNPL late fees capped?
There’s no federal cap for pay-in-4 plans. New York’s proposed rules would cap late fees at $8, and some lenders set their own limits or charge no late fees.
