“Buy now, pay later,” or BNPL, is a type of installment loan. It divides your purchase into multiple equal payments, with the first payment due at checkout. The remaining payments are billed to your debit, credit card or bank account until your purchase is paid in full.
BNPL plans don’t usually charge interest, though some may charge fees, depending on the provider. There’s also no hard credit check to get approved, unlike a credit card or loan.
These features have made BNPL a popular payment option for consumers. More than half of Americans (55%) say they’ve used buy now, pay later services, according to a NerdWallet survey conducted online by The Harris Poll .

How does buy now, pay later work?
You’ll typically see BNPL payment plans when you check out online on a retailer’s website or you can shop directly through a BNPL provider’s mobile app. For in-store shopping, providers offer virtual cards you save to your mobile wallet and use at the register.
To sign up for a BNPL service, you’ll fill out a short application, which may ask for information like your name, email address, date of birth, phone number and Social Security number. You'll also provide a payment method. Then, the BNPL provider will perform a soft credit check, which won't affect your credit score, and approve or deny your application in seconds.
The plan you’re offered will vary by provider, but many providers use a “pay-in-four” model, which divides your purchase into four equal installments, each due two weeks apart, with the first payment due immediately.
For example, if your total purchase is $200, you'll pay $50 at checkout, then have three remaining payments of $50, each due two weeks apart. As long as you make all payments on time, you'll pay off your purchase in six weeks.
Pay-in-four plans almost never charge interest. Longer-term BNPL plans, where payments are spread out over months or even years, may charge an annual percentage rate up to 36%.
Providers may charge various fees. Late fees are the most common fee, and are usually capped at 25% of the purchase value. Some providers also charge failed payment fees, payment rescheduling fees, service fees or origination fees.
How to get approved for buy now, pay later
Approval criteria varies by BNPL provider, but even if you have bad credit, you can still get approved, since most providers consider multiple factors when reviewing your application. Here’s what they’ll be paying attention to:
Credit score and credit history.
The cost of your purchase.
The funds available on your chosen payment method, such as your debit card.
Any prior history with that provider, including how long you’ve had an account, past purchases, payment history, outstanding loans, etc.
One of the best ways to increase your chances of getting approved for a BNPL loan is to start with a small purchase that you can pay off on time or early. This builds a positive repayment history with the BNPL company and may help you get approved for a larger purchase in the future.
Does buy now, pay later affect your credit score?
In June 2025, the credit score company FICO announced it would start incorporating BNPL loan data into credit scores . The new scoring models are available this fall, says FICO, but it's unclear if or when consumers will start seeing a direct impact on their scores. Some providers have opted not to participate in this new scoring model.
To be on the safe side, make sure to always repay your BNPL loans on time, and try to avoid loan stacking, which is when you take out multiple BNPL loans at a time . Loan stacking makes payments harder to keep track of, and it may increase your overall credit utilization, which could hurt your score.
Should you use buy now, pay later?
There are several things to consider when deciding whether to use a BNPL payment plan.
Is your purchase necessary? NerdWallet recommends using BNPL only for essential purchases you can’t do without, like a mattress. Though these plans may seem simple and affordable, you’re still taking on debt, and it’s rarely a good idea to go into debt for a nonessential item.
Does the plan charge interest? Look for a BNPL plan with no interest. This will make it easier for you to pay back the loan, since you’re not paying more on top of the initial purchase.
Can you cover the payments plus other expenses? If you’re struggling to pay your bills or start an emergency fund, steer clear of buy now, pay later. Because of its convenience, it’s easy to overspend with BNPL, and you may end up owing more than you can repay.
When shouldn’t you use buy now, pay later?
Though BNPL may seem like a convenient payment option, it’s still a loan, and it has risks, including falling behind on payments and taking a hit to your credit score.
If you don’t need to make the purchase, or if you’re not sure you can keep up with the payments for the duration of the loan for any reason, you shouldn’t use BNPL.
Did you know?
The Consumer Financial Protection Bureau released a report in January 2025 that shows the majority of BNPL loans are held by borrowers with subprime or deep subprime credit scores (meaning borrowers with bad credit) . BNPL users also tend to hold larger amounts of other unsecured debts, like credit cards, than non-BNPL users. Though the CFPB doesn’t draw direct conclusions from this report, it suggests that BNPL users may be particularly financially vulnerable and should exercise caution around these apps.

Pros of BNPL
No interest: Most BNPL apps charge zero interest for their pay-in-four loans. That means if you make all payments on time, you use the service for free. It’s rare to be able to finance a purchase, especially a bigger ticket item like a computer, at zero interest.
No hard credit check: Unlike credit card or loan providers, BNPL apps don’t usually conduct a hard credit pull, which temporarily knocks a few points off your score. Also, if you’re worried about a low credit score, you may have an easier time getting approved by a BNPL app than a traditional lender.
Simple, convenient and fast financing option: BNPL providers pride themselves on the simplicity and ease of their payment plans. Loan applications are short, and providers can approve you instantaneously, usually without ever leaving a retailer’s checkout screen.
Cons of BNPL
Could encourage overspending: Research has shown that people tend to spend more when they use BNPL, because purchases seem smaller and their budgets feel more flexible . For example, if you plan to spend no more than $100 at checkout, and you opt into a pay-in-four plan, you’ll only pay $25 upfront. It may be tempting, then, to fill up your cart with more items.
Unlikely to build credit: BNPL is not a reliable way to build credit, even with the new scoring models. If building credit is a priority for you, it's better to go with a more established financial product, like a credit card or credit-builder loan.
Fees: Though some BNPL apps won’t charge any fees, many do — especially if you miss a payment. Fees for late or rescheduled payments typically range from $2 to $17, represent a significant percentage of the total and increase the overall cost of your purchase.
Customer service issues: Some BNPL users have trouble settling disputes. For example, if you buy an item you need to return, you must deal directly with the store, even though your loan is through the BNPL lender. This can delay your refund, and you may be stuck making biweekly payments in the meantime.
