Buy now, pay later: when it helps and when it hurts

At checkout you'll often see an offer to split your purchase into four payments. These buy now, pay later (BNPL) loans can be useful, but they are still loans. Here's what to know before you use one this holiday season.

Key takeaways

A typical BNPL plan splits the cost into four or fewer payments, often interest-free.
Late fees are the main cost, and it is easy to lose track of several plans at once.
A discount is only a deal if you could have paid for it anyway.

How BNPL works

According to the CFPB: What is a Buy Now, Pay Later loan?, BNPL is a type of installment loan that usually lets you buy something now with little or no upfront payment and pay the rest in four or fewer payments. A common setup is four interest-free payments every two weeks, with the first one due at checkout. Most BNPL loans don't need a hard credit check, but you'll usually need a debit card, credit card or bank account for payments.

The costs people miss

Late fees. Many plans don't charge interest, but most charge a fee if you miss a payment.
Stacking. Three or four plans at once can mean a payment almost every week.
Overdrafts. Autopay from a checking account that's running low can trigger bank fees.
Longer plans. Larger, longer-term BNPL loans can charge interest, just like other loans. Read the terms.
Returns. If you return an item, the refund process can take time, and you may still need to keep making payments until it's processed. Check the provider's rules.

What about your credit score?

Whether BNPL affects your credit depends on the lender and the type of loan; some report payments to the credit bureaus and some don't. See CFPB: Will a BNPL loan affect my credit scores?.
