Buy now, pay later isn’t just a trending checkout button; it’s become a major part of how people pay.
In fact, the Federal Reserve Bank reported that nearly 1 in 5 U.S. adults used a BNPL service in the past year, and the number of BNPL users has continued to climb—especially among people who want interest-free payments and clear payoff dates instead of mounting credit card balances.
And here’s the good part: most of those purchases were made using zero-interest Pay in Four plans, meaning no interest charges, no revolving debt, and no hit to your credit score. But as BNPL grows, so do your options. And simply put, some of them do come with interest, longer terms, and fine print you’ll want to understand first.
Key Takeaways
- Pay in Four = Interest-free payments: Most BNPL services let you split purchases into four equal installments across six weeks with no interest charges.
- Monthly BNPL loans may include interest: Longer plans are more like installment loans or personal loans, and may include APRs based on your creditworthiness.
- No hard credit check for short-term plans: Most BNPL providers only use a soft credit check, so credit scores aren’t affected.
- Missing payments matters: Late fees, paused accounts, and negative reports to credit bureaus can happen—especially with programs that report payment history like Sezzle Up or Affirm Monthly.
- Still easier than credit cards for many people: BNPL loans offer clear payoff schedules, no revolving balance, and—unlike credit cards—no compounding interest if you stay on track.
How BNPL Interest Rates Work
Most BNPL services (like Sezzle, Afterpay, Klarna, PayPal Pay in 4) offer interest-free payments when you make four installments over six weeks. You pay 25% at checkout (first payment), then three more automatic payments.
But here’s where interest comes in:
| BNPL Type | Interest? | Typical Terms |
|---|---|---|
| Pay in 4 | No interest, no APR | 4 payments over 6 weeks |
| Monthly financing | Interest may apply | 3–24 months |
| Larger purchases | Interest or service fees are possible | Credit approval required |
| Missed payments | Late fee applies | Could be reported to credit bureaus |
More BNPL companies are expanding beyond small online purchases. They now finance larger purchases, like travel, furniture, laptops, or medical bills, sometimes through partner banks like Truist Bank or WebBank. These longer-term BNPL loans act more like traditional installment loans.
Why Interest-Free BNPL Still Matters
Even though some plans have interest, about half of all BNPL users still choose Pay in Four because:
- It avoids credit card interest rates (currently averaging 22–30% APR according to the Federal Reserve Bank).
- There’s no revolving debt; just pay four payments, and it’s over.
- Many with lower credit scores or no credit history can still be approved.
- Payments come directly from your bank account, debit card, or PayPal Pay instead of a credit limit.
What Affects Whether You’ll Be Charged BNPL Interest?
BNPL providers decide interest rates based on a few factors—not just credit scores.
BNPL Interest Depends On:
- Purchase amount – larger purchases may trigger longer loan terms.
- Loan terms – anything longer than six weeks may charge interest.
- Credit history/Payment history – even though approval uses a soft credit check, repayment history matters.
- BNPL usage – too many active loans can trigger declines or higher rates.
- Provider policies – Affirm, Klarna, and PayPal all have different rates and fees.
How to Avoid Paying Interest on BNPL Loans
Want to keep it truly interest-free? Here’s how:
- Stick to Pay in 4 plans
- Make every payment on time; avoid late or rescheduled payments
- Don’t stack too many active BNPL plans
- Avoid using BNPL for cash equivalent purchases like gift cards or money orders
- Use apps with financial protection (like Sezzle’s repayment alerts)
- Only borrow what fits your budget—not the maximum amount you’re approved for
BNPL vs Credit Cards: Which Has Higher Interest Rates?
| Feature | BNPL | Credit Cards |
|---|---|---|
| Interest | $0 on Pay in 4 | 22%–30% APR on average |
| Fees | Late fees only | Interest + late fees + penalty APR |
| Credit check | Soft credit check | Hard inquiry |
| Payoff structure | Fixed payments | Revolving balance |
| Credit impact | Depends on the provider | Always reported to credit bureaus |
So while BNPL loans for 12–18 months can charge interest, they usually have a lower interest rate than many credit cards—especially if your credit score isn’t perfect.
