PayPal Credit has spent years marketing itself as the easy way to split purchases into six months of interest-free payments.
What the checkout screen doesn't shout about is what happens after that grace period ends.
Miss the payoff window, and your balance starts accruing interest at a 29.99% annual rate — one of the steepest you'll find outside a payday lender.
That number deserves a closer look, because it's buried in the fine print while the "0% for 6 months" banner gets top billing.
For a $600 purchase you don't finish paying off, you're looking at roughly $15 a month in interest alone.
On a $2,000 balance, you're bleeding about $50 monthly just to stand still.
Here's the mechanic that trips people up: PayPal Credit applies your payments to the promotional balance first, not the high-APR one.
If you're carrying both a 0% promo purchase and older interest-bearing debt, your money may clear the cheap balance while the expensive one compounds in the background.
Consumer advocates have flagged this payment-allocation ordering for years.
The six-month clock typically starts at the purchase date, not your statement date, so you may get closer to five months of runway than you think.
And the promotional window doesn't pause if you return an item or get a partial refund — the deadline stays put.
PayPal and its lending partner, obviously, plus the retailers who see bigger cart sizes when financing is one click away.
Synchrony Bank, which issues the credit line, books the interest when shoppers slip.
The shopper benefits only if they hit the payoff date precisely — a discipline most households juggling groceries, rent, and rising card balances struggle to maintain.
Store cards, buy-now-pay-later apps, and even some major bank cards run similar deferred-interest traps.
But PayPal Credit's 29.99% rate sits near the top of the range.
For context, the average credit card APR in the U.S. has hovered around 20% to 24% in recent years, so you're paying a real premium for the convenience.
If you're already carrying a PayPal Credit balance past its promo period, the math is unforgiving.
Minimum payments mostly cover interest, so the balance can linger for years.
A balance transfer to a lower-rate card, a personal loan, or even a side gig to knock it out fast usually beats coasting.
The smarter play is to treat the six-month window like a hard deadline with a buffer.
Divide the purchase by five, not six, and set autopay for that amount.
If you can't cover the full balance in five months, the 0% offer isn't really an offer — it's a loan at 29.99% with a free trial attached.
None of this means PayPal Credit is a scam.
It's a legal product with disclosed terms.
But disclosure isn't the same as clarity, and a checkout button that says "easy payments" isn't telling you the whole story.
Our take: deferred-interest financing works beautifully for people who never need it and punishes the people who do.
Final Thoughts
Before you click that button, do the five-month math — and if the answer is uncomfortable, that's your answer.
