Buy Now, Pay Later (BNPL) is a payment service that lets you purchase an item up front, then pay it off in installments. While it can help you get items faster, stacking multiple payment plans can start working against your future self.
Why does BNPL feel free (but isn’t)?
BNPL services can be tempting because they tap into a simple idea: "I’ll get the item now and deal with the rest later". By breaking a large purchase into smaller payments, your wallet doesn’t take as big a hit today. It can feel free in the moment, but when the ‘later’ part catches up, those tiny payments stack up, and eventually feel like any other bill.
How small debt compounds into stress
We often talk about how small, consistent investments can build potential over time, but debt has a compounding effect, too.
When you have one BNPL plan, it’s easy to track. When there’s 3 or 4, they become 3 or 4 small loans stacked on top of your existing bills.
According to CNBC, 63% of people who used BNPL took out multiple loans at the same time, and a third of them borrowed from multiple lenders at once. Each payment might still feel manageable on its own, but once you factor in interest and how long those loans run, the real cost starts to add up.
How stacking looks like from both sides
The "stacking" method works both ways. You can either stack obligations that take away from your future, or stack assets that add to it.
How stacking micro-debt can affect you
Let’s say you opted for BNPL on 3 different items. Here’s what that could look like:
- Purchase 1: $200, but you only pay $20 bi-weekly
- Purchase 2: $150, but you only pay $15 bi-weekly
- Purchase 3: $600, but you only pay $30 bi-weekly
That's $65 every 2 weeks. In this scenario, "future you" is constantly paying for "present you."
How stacking micro-investing can affect you
Now, let’s use that stacking effect for your goals instead:
- You set up a $10 Recurring Investment with Acorns, paid bi-weekly ($20/month)
- You enable Round-Ups® to invest spare change, where on average, customers invest $45/month
That’s $65/month. Over time, your money can eventually tap into the power of compounding, where those small "stacks" can potentially grow into something mighty over the long term. In this scenario, "present you" is setting "future you" up for financial wellness.
How to shift away from dealing with it later
Breaking the BNPL habit starts with recognizing what it actually normalizes. As Acorns CEO Noah Kerner said in a conversation with Axios: "The real danger of Buy Now, Pay Later isn't whether it appears on your credit score — it's that it normalizes spending money you don't have, on things you don't need, without fully understanding the consequences."
Shifting away from dealing with the costs later takes time, but can set you up to be more financially free. Here’s where to start:
- Slowly build an Emergency Savings fund. People typically opt in to BNPL services because they don’t have the money upfront. With an Emergency Savings fund, you can build a safety net over time while earning a high APY. When an emergency arises, you have the funds readily available to help out.
- Build small, consistent investing habits. You can stack micro-investments the same way you stack debt. By tapping into our automated tools, like Round-Ups® and Recurring Investments, you can invest for your future without even thinking about it.
Don't let "future you" pick up the tab for today. Start stacking in the right direction. 🌱
Frequently Asked Questions
What is the real cost of "pay later"?
Is micro-investing better than paying off debt?
If you have high-interest debt, it’s usually best to pay that off first. However, you don't have to wait to be debt-free to start investing. You can invest spare change while you pay off what you owe to help build strong, investing habits over time
Why is BNPL considered "micro-debt"?
It’s called micro-debt because the individual amounts are small — often under $50 — making them feel insignificant. However, because they are so easy to sign up for, customers can easily accumulate many of them at once, leading to a large total debt load.
