PayPal Credit has long been the quiet workhorse of online checkout, letting shoppers split purchases into six months of no-interest payments, then quietly rolling the balance into a standard credit line.
That second act is where the story turns.
For many users, the annual percentage rate on that revolving balance now sits near 29.99%, among the steepest of any major consumer credit product.
The 0% promotional offer applies only if you pay the full balance within the six-month window.
Miss that deadline by even a day, and interest can be applied retroactively to the original purchase amount, not just the remaining balance.
On a $1,200 purchase, that can mean a surprise charge of well over $100.
The Federal Reserve's benchmark rate has stayed elevated for much of the past two years, and card issuers have passed that cost straight to consumers.
The average retail credit card APR now hovers above 30%, and store-branded and digital wallets like PayPal Credit have climbed right alongside it.
Meanwhile, the money coming in hasn't kept pace.
Grocery bills are up sharply since 2020, rent in most metros has climbed double digits, and auto insurance has jumped for many households.
When essentials eat more of each paycheck, the six-month payoff window gets harder to hit, and more shoppers slide into the interest-bearing phase.
The result is a squeeze that sneaks up on people.
A shopper who uses PayPal Credit for holiday gifts or a new laptop in October may not feel the pinch until spring, when the promotional period ends and the balance starts compounding at nearly 30%.
By then, the purchase often costs more than it would have with a plain debit card.
There are practical ways to soften the blow.
Set a calendar reminder for two weeks before any promo period ends, and pay the balance in full even if it means trimming elsewhere.
If you can't, contact PayPal before the deadline to ask about a payment plan, since some hardship options exist but rarely get advertised.
And treat any 0% offer as a deadline, not a discount.
The bigger lesson is about how these products are marketed. "No interest if paid in full" sounds like a favor.
Structurally, it's a bet that a meaningful share of users won't make the deadline, and the 29.99% rate is the payout when they don't.
That's not a scam, but it's not charity either.
Our take: PayPal Credit can still be a useful tool for disciplined shoppers who pay on time, but it deserves the same wariness as any store card.
Read the terms before you click, and never let a promotional deadline drift past you.

The rate you avoid is the deal you actually got.
