Bought something on Prime Day with "4 interest-free payments"? Your second payment is probably due around now, with two more to follow.
Multiply that by millions of shoppers. Adobe projected that buy now, pay later would account for $2.04 billion of online spending during the June 23–26 event, up 5.5% from last year and 7.8% of all Prime Day sales (Adobe, via Shopifreaks).
Why this year's timing matters
Amazon moved Prime Day from July to June 23–26 this year. Shoppers spent $8.3 billion online on the first day alone, beating Adobe's forecast, and the four-day event was projected to reach $26.3 billion (Yahoo Finance).
A typical pay-in-4 plan charges the first payment at checkout, then one every two weeks. For a purchase made June 24, that's roughly:
| Payment | Approximate date |
|---|---|
| 1 of 4 | June 24 (at checkout) |
| 2 of 4 | Around July 8 |
| 3 of 4 | Around July 22 |
| 4 of 4 | Around August 5 |
Your actual dates depend on the provider. Check your app.
Several of those land right next to rent, back-to-school shopping and your card due date.
The real risk isn't one loan. It's five.
The CFPB studied BNPL borrowers and found that about 63% had more than one loan going at the same time at some point in the year, and a third had loans from more than one BNPL company. BNPL borrowers also carried higher balances on credit cards and other loans than non-users (CFPB).
Here's the catch: BNPL loans have mostly not been reported to the credit bureaus, the CFPB noted. So nobody, including you, gets one clear view of everything you owe.
Run the numbers
Three Prime Day purchases, each split into four:
| Purchase | Total | Each payment |
|---|---|---|
| Headphones | $160 | $40 |
| Air fryer | $120 | $30 |
| Patio set | $480 | $120 |
| Every two weeks | $190 |
$190 every two weeks is about $380 a month for six weeks. If a payment bounces and you cover it with a credit card at the 21.52% average rate the Fed reports for accounts charged interest (Federal Reserve, G.19), "interest-free" just became expensive.
Fee check
- Late fees: many BNPL providers charge one if a payment fails. Know the amount in your app.
- Your bank: a failed automatic payment can also trigger an overdraft or returned-payment fee from your bank.
- Paying BNPL with a credit card: some providers allow it. You're then paying card interest on an "interest-free" plan.
- Longer BNPL plans: not all plans are 0%. Monthly plans over longer terms can carry interest. Check the APR before you click.
How to get through the next six weeks
- Open every BNPL app you used and write down each remaining payment and its date.
- Put them in one calendar next to your rent and card due dates.
- Make sure the linked account will have the money on each date, or switch the payment to an account that will.
- Pause new BNPL purchases until these are paid off. Stacking is how a few small plans turn into a real problem.
Do this today: add up every BNPL payment still due between now and mid-August. That's money already spent, so take it out of your budget now.
