PayPal Credit has long been the checkout option that lets you split a purchase into easy monthly chunks.
But the interest rate on those chunks is climbing, and a lot of shoppers won't notice until the balance already feels heavy.
The headline number is a 0% promotional offer for six months on purchases of $99 or more.
The catch is what happens after the window closes.
Standard terms on PayPal Credit now carry an APR near 29.24%, and that rate is variable — meaning it moves with the broader market rather than sitting still.
If you carry a balance past the promo period, that number starts working against you fast.
To understand why, look at what's been happening with rates overall.
The Federal Reserve spent much of 2022 and 2023 pushing its benchmark rate higher to cool inflation.
Credit card APRs track that benchmark closely, and store financing and buy-now-pay-later products often follow the same path.
Even as inflation has eased from its peak, the average credit card rate has stayed stubbornly high, hovering above 20% for most cards and pushing toward 30% for store-brand and subprime products.
PayPal Credit sits right in that expensive zone.
Food prices are still up roughly 20% to 25% compared with four years ago, depending on which basket you measure.
Rent has climbed even more in many metros.
Wages have risen too, but for a lot of households they haven't kept pace with the combined cost of food, housing, and transportation.
That squeeze is exactly what makes a 0% promo so tempting at checkout — and exactly what makes the post-promo rate so dangerous.
You buy $600 worth of stuff, get six months interest-free, and pay the minimum each month.
The minimum on these accounts is often a small percentage of the balance, sometimes just $25 or $35.
The remaining $400 starts accruing interest at roughly 29%.
Now the monthly minimum barely covers the interest, and the balance barely moves.
The fix isn't complicated, but it takes discipline.
Divide the purchase by the number of promo months and pay that amount, not the minimum.
If you bought $600 with a six-month offer, that's $100 a month.
Set an autopay for it the day you check out, before the excitement of the purchase wears off.
Also check which purchases the promo actually applies to.
PayPal Credit runs separate promo windows for different transaction types, and a single statement can carry balances at multiple rates.
If you're not sure which balance is which, call and ask before you pay extra — payments usually go to the lowest-rate balance first, which can leave the expensive balance growing.
One more thing worth knowing: PayPal Credit reports to the major bureaus, so a maxed-out line can drag down your credit utilization and, in turn, your score.
That matters if you're planning to apply for a mortgage or auto loan soon. **Our take:** A 0% promo is a useful tool if you can pay it off inside the window, and a costly one if you can't.
Final Thoughts
Treat the deadline as a hard date, automate the payment, and don't let a checkout convenience turn into a 29% habit.
