PayPal Credit has spent years marketing itself as the easy way to split a purchase into six months of "no interest" payments.
What the checkout button doesn't shout about is what happens after those six months: a standard APR that currently sits around 31%, depending on your account, applied retroactively to the entire original purchase.
That deferred interest trap is the part most shoppers miss.
Miss a single payment, pay late, or simply fail to clear the full balance by the promo deadline, and you don't just owe interest going forward.
You owe interest on the full amount from day one, as if the promotional period never existed.
Put a $1,200 couch on a six-month plan and pay $180 a month.
But pay $150 a month, miss the deadline by a few weeks, and you can suddenly owe $300 or more in accumulated interest on top of the balance.
That's the entire promotional savings reversed in one billing cycle.
The bigger question is who this structure actually serves.
Synchrony Financial, which issues the PayPal Credit line, reported billions in interest and fee revenue last year.
Deferred-interest products are a well-known profit engine precisely because a meaningful share of customers don't finish the race in time.
The "no interest" pitch gets you in the door; the 31% rate is where the money is made.
Compare that rate to what else is out there.
The average credit card APR hovers around 21% to 24% right now.
A personal loan from a credit union might run 10% to 14% for good credit.
PayPal Credit's standard rate is at the high end of consumer borrowing, and it's not because the risk is higher.
It's because the promotional hook lets them bury the real cost.
PayPal Credit lines are often small, sometimes a few hundred dollars, and usage is reported to the credit bureaus.
Max out a $500 line and your credit utilization ratio takes a hit, which can ding your score even if you pay on time.
That matters if you're shopping for a mortgage or auto loan in the next year.
If you use PayPal Credit, treat the promo deadline like a hard bill, not a suggestion.
And if you can't clear the balance in time, consider paying it off with a lower-rate personal loan before the deferred interest triggers.
Read the terms at checkout, because the APR and the retroactive interest language are both there, just small.
PayPal Credit isn't evil, and for disciplined borrowers who pay in full, it's a free short-term loan.
But the product is engineered so that the people who need the most flexibility are the ones who pay the most for it.
Our take: deferred interest is one of the most consumer-hostile tricks in retail finance, and "no interest for six months" deserves the same skepticism as any too-good-to-be-true offer.
If you can't pay it off early, you're better off with a plain low-rate card or a credit union loan.
