Buy now, pay later: the hidden risks before you click

Splitting a purchase into four payments feels painless at checkout. The problems show up later, usually all at once.

"Pay in 4 interest-free payments." It sounds like free money. For many people it works fine. For others it becomes a pile of small debts they lose track of.

How buy now, pay later works

The CFPB describes BNPL as a type of loan that splits a purchase into smaller payments, often four, with the first due at checkout. Many plans pull the payments automatically from your debit card or bank account.

A CFPB study documented how quickly this lending grew and flagged concerns about consumers taking several loans at once.

The risks nobody shows at checkout

• Loan stacking: three or four plans running at the same time, each one small, together taking a big bite of each paycheck.
• Late fees when a payment fails.
• Overdraft fees from your bank if autopay hits a debit account with not enough money.
• Returns get complicated: you deal with the store and the lender, and installments may keep coming until the refund is processed.
• Spending more: splitting the price makes it feel smaller than it is.

Using it safely

1. Only for purchases you had already planned and could pay in full.
2. One plan at a time.
3. Pay with a card that has fraud protections rather than directly from a thin checking account.
4. Put every due date in your calendar.
5. Count BNPL payments in your monthly budget as fixed bills.

A simple alternative

Save the four payments first and buy the item in the fifth week. Same money, no risk of fees, and you find out if you still want it.
