PayPal Credit has long marketed itself as the buy-now-pay-later option with a friendly face: no interest if you pay your balance in full within six months.
What the promotional banners tend to bury is the number that kicks in when you don't.
That standard APR sits around 29.99%, and for a growing number of cardholders, it's now the most expensive debt in their wallet.
Here's how the math actually works, because the gap between the pitch and the fine print is where people get hurt.
Buy a $600 laptop with PayPal Credit and pay it off inside the promotional window, and you owe exactly $600.
Miss that deadline, even by a few days, and the deferred interest doesn't just start from your remaining balance.
In many cases it's retroactive, meaning interest can be calculated back to the original purchase date.
A balance that felt manageable can balloon fast.
That distinction matters more now than it did a few years ago.
With the Federal Reserve holding its benchmark rate elevated through much of the past two years, variable-rate consumer credit has stayed pricey.
Store cards and retail financing products tend to sit at the high end of that range, and PayPal Credit is no exception.
Compare it to a typical credit union card in the mid-teens, and the spread is stark.
The trap isn't unique to PayPal, but its checkout integration makes it uniquely easy to stumble into.
The option appears at millions of online checkouts, often pre-selected or displayed prominently next to the regular payment button.
Shoppers click through in seconds, focused on the "0% for 6 months" headline, not the 29.99% that follows.
A few practical moves can keep you out of trouble.
First, treat any promotional financing like a deadline with teeth: set a calendar reminder at least two weeks before it ends, not the day of.
Second, if you can't clear the full balance, consider whether a lower-rate alternative, like a 0% intro APR card or a small personal loan, makes more sense before the promo expires.
Autopay failures and partial payments are common ways people accidentally trip retroactive interest.
It's also worth knowing that PayPal Credit reports to the major credit bureaus.
On-time payments can help your score; a maxed-out line or a missed payment can sting.
That cuts both ways, and it's a reason to treat the account like real credit rather than a checkout shortcut.
The bigger picture is that BNPL-style products are under more scrutiny than ever.
Regulators have pushed for clearer disclosure of fees and interest, and some lenders have already trimmed or restructured their promotional offers.
PayPal hasn't announced a headline rate hike tied to this specific product, but the underlying cost of consumer credit remains elevated, and that pressure rarely works in borrowers' favor.
For households already stretched by grocery bills and rent, a 29.99% APR isn't a footnote.
It's the difference between paying off a purchase and paying for it twice. **Our take:** PayPal Credit can be a genuinely useful tool for disciplined shoppers who treat the six-month window as a hard deadline and never carry a balance past it.
For everyone else, it's one of the easier ways to accidentally sign up for some of the most expensive debt available at checkout.
