Like its name suggests, "buy now, pay later" lets you make a purchase and receive it immediately, but pay for it at a later time, usually over a series of installments.

Though this type of payment plan has been available for years, it exploded in popularity during the pandemic as more people shifted to online shopping.

Most major retailers now offer some type of buy now, pay later plan, but whether you should opt in depends on the plan and your financial situation.

What is buy now, pay later?

Buy now, pay later, or BNPL, is a type of installment loan. It divides your purchase into multiple equal payments, with the first due at checkout. The remaining payments are billed to your debit or credit card until your purchase is paid in full.

These plans can come with interest and late fees, though some plans, depending on the provider, charge neither.

You’ll mostly see BNPL payment plans when you shop online, although some plans are available in stores.

How does buy now, pay later work?

During check out, you’ll see an option to break up your total purchase and pay a smaller amount now, instead of the full balance.

If interested, you’ll fill out a short application directly on the checkout screen. It may ask for information like your name, address, date of birth and phone number. You will also provide a payment method. Then, the BNPL provider may perform a soft credit check, which won't affect your credit score, and approve or deny your application in a matter of seconds.

Approval criteria vary, but even if you have bad credit or no credit, you may still be eligible.

The plan you’re offered will also vary by provider, but many companies offer a “Pay in 4” 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 $300, you will pay $75 at checkout, then have three remaining payments of $75, each due two weeks apart. As long as you make all payments on time, you will have paid off your purchase in six weeks.

While Pay in 4 doesn’t usually charge interest, other BNPL plans can charge an annual percentage rate up to 30%. Late fees range from $7 to $8 and are usually capped at 25% of the order value.

Should you buy now, pay later?

There are several things to consider when deciding whether to choose a BNPL payment plan.

NerdWallet recommends using BNPL only for necessary expenses, like a mattress for your apartment or a computer for school. Though the plan may seem simple and low-cost, you’re still taking on debt, and it’s rarely a good idea to go into debt for a nonessential purchase.

You’ll also want to look for a BNPL plan with zero to minimal interest. This will lower your monthly payments and make it easier for you to pay back the loan.

If you’re struggling to pay your bills or start an emergency fund, steer clear of buy now, pay later. Because of its ease and convenience, it’s possible to overspend with BNPL. You may incur high late fees or be sent to collections, which will hurt your credit score.

BNPL pros

BNPL cons

  • Zero-interest plans available.

No minimum credit score required.

  • Offered at most major retailers during online checkout.

  • Some plans may charge interest.

  • Some plans may charge late fees.

  • Payments may not be reported to the three main credit bureaus.

  • Easy to overspend.

For some shoppers, paying with alternatives like credit cards may be a smarter financing choice. Not only do most credit cards earn rewards or cash back, but they also report on-time payments to the credit bureaus, which not all BNPL companies do. A history of on-time payments can help build your credit score and open the door to more affordable financing options in the future.

In December 2021, the Consumer Financial Protection Bureau announced an inquiry into buy now, pay later, expressing particular concern about debt accumulation, lack of regulation and data harvesting. The CFPB is expected to publish its findings.
