PayPal Credit has spent years marketing itself as the easy way to split a purchase into six interest-free payments.
The pitch shows up at checkout on everything from sneakers to airline tickets.
What the ads don't lead with is the number that kicks in the moment you miss a due date or stretch the balance past six months.
That number is currently around 29.99% APR, depending on your account.
It's a variable rate, which means it can move with the broader market.
And it applies not just to new purchases but often retroactively to the entire balance if you slip up on the promo terms.
Here's how the six-month plan actually works.
You get no interest if you pay the full balance within the promotional window, usually six months from the purchase date.
Miss that deadline by a single day, and interest can be charged from the original purchase date, not from the day you missed.
That retroactive hit is the part that catches people off guard.
The structure mirrors store credit cards, which have long used deferred-interest offers to drive big-ticket sales.
Retailers love it because it moves inventory.
PayPal loves it because a slice of customers will inevitably carry a balance.
The consumer is the one holding the timing risk.
A $1,200 purchase paid down to $200 by month six leaves you owing interest on the full $1,200 for six months at roughly 30%.
It's a bill that can quietly balloon well past what you thought you signed up for.
Used exactly as designed, it's free short-term financing.
The problem is that "exactly as designed" requires discipline, calendar reminders, and a budget that doesn't wobble when an unexpected expense hits.
PayPal Credit is a revolving line, so it can affect your credit utilization ratio, which is a meaningful chunk of your credit score.
Opening a new line typically triggers a hard inquiry.
Neither is catastrophic, but neither is free either.
If you're weighing whether to use it, a few practical checks help.
Set an automatic payment that clears the full balance before the promo ends, not just the minimum.
Screenshot the exact expiration date at checkout, because it's easy to lose track.
And if you can't cover the full amount within six months, a low-rate balance transfer card or simply saving up may cost you less.
The bigger point is that "0%" is a marketing frame, not a promise.
The real rate is whatever you pay when the clock runs out.
Our take: PayPal Credit can be a useful tool for people who treat the six-month window like a hard deadline and never miss it.
For everyone else, it's a deferred-interest trap dressed up as a convenience.
