'Buy now, pay later' has gone mainstream, but personal finance expert warns of risks

# Buy Now, Pay Later Has Gone Mainstream — But the Hidden Risks Could Reshape Consumer Finance

Nearly half of all Americans have now used "buy now, pay later" installment plans for online purchases, and roughly 10% use them regularly, according to new data that confirms what was already obvious to anyone who's shopped online recently: BNPL has moved from a niche fintech curiosity to a core feature of consumer spending. But as the industry crosses the mainstream threshold, the warnings from financial experts are growing louder — and the regulatory reckoning may be approaching faster than the industry would like.

## The Numbers Tell a Complicated Story

The adoption figures are staggering. BNPL transaction volume in the United States exceeded $80 billion in 2025, more than quadruple the volume from just three years earlier. Affirm, Klarna, Afterpay, and a growing roster of competitors have embedded their services at checkout across virtually every major e-commerce platform. Apple Pay Later's entry into the market in 2024 validated the category permanently — when Apple builds a product in your space, you've arrived.

But beneath the growth numbers, the risk signals are flashing. The Consumer Financial Protection Bureau has reported that BNPL users are significantly more likely to also carry credit card debt, use overdraft protection, and have lower credit scores than non-users. This isn't a coincidence. BNPL's core business model — offering instant, frictionless credit at the point of purchase — systematically selects for consumers who are most vulnerable to overextension.

## Why BNPL Is Different From Traditional Credit

The fundamental difference between BNPL and traditional credit cards isn't the interest rate — many BNPL plans charge zero interest if you pay on time. It's the psychological architecture of the product.

Traditional credit cards create a single, visible balance that accumulates over time. You can see your total debt in one place. BNPL fragments that visibility. A $400 purchase split into four payments of $100 feels like spending $100, not $400. A consumer using three different BNPL services simultaneously — one for a laptop, one for clothes, one for furniture — can accumulate hundreds of dollars in monthly obligations without ever seeing the total picture.

This fragmentation is a feature, not a bug, from the BNPL providers' perspective. The less visible the total debt burden, the more likely consumers are to keep using the service. And the data bears this out: BNPL users spend 10-40% more per transaction than they would with a credit card or debit card, according to multiple academic studies.

## The Regulatory Storm Is Building

The CFPB has been circling BNPL for over two years. In 2024, the bureau issued an interpretive rule declaring that BNPL lenders must comply with the same consumer protection laws that govern credit card companies — including requirements for dispute resolution, periodic billing statements, and penalty fee limitations. The industry pushed back hard, arguing that BNPL isn't credit because most plans don't charge interest.

That argument is becoming harder to sustain. Late fees on BNPL plans can be substantial — Afterpay charges up to 25% of the purchase price in late fees for missed payments, which when annualized represents an effective interest rate that would make a payday lender blush. And the industry's own data shows that roughly one in five BNPL users has incurred a late fee in the past year.

Several states are now moving independently. California, New York, and Massachusetts have all introduced legislation that would cap BNPL fees, require credit checks before approval, and mandate that providers report to credit bureaus. If even a few of these bills pass, the economics of BNPL change dramatically — because a significant portion of current users would not qualify under traditional underwriting standards.

## Who Benefits and Who Gets Hurt

The BNPL industry argues that its products expand access to credit for underserved consumers who can't get approved for credit cards. And this is partially true — BNPL approval rates are significantly higher than credit card approval rates, particularly for younger consumers and those with thin credit files.

But expanding access to credit and expanding access to debt are not the same thing. The critical question is whether BNPL helps consumers smooth consumption over time — buying necessary goods when cash is tight but paying them off reliably — or whether it enables systematic overconsumption that leaves consumers worse off.

The evidence is mixed but troubling. A Federal Reserve Bank of New York study found that BNPL use is concentrated among consumers who are already financially stressed. These are not primarily consumers using BNPL as a rational cash-flow management tool. They are consumers using BNPL because they have run out of other options.

## What This Means For You

If you use BNPL services, the most important thing to understand is that "zero interest" does not mean "free." You are trading the discipline of paying upfront for the risk of accumulating fragmented obligations that are harder to track and easier to lose control of. Treat BNPL the way you'd treat a credit card: set a hard monthly limit across all services, never use more than two BNPL plans simultaneously, and never finance a purchase you couldn't afford to pay in full today. For investors, the BNPL sector faces a binary risk: either regulation stays light and growth continues, or regulation tightens and the business model's profitability collapses as approval rates fall and fee income shrinks. For policymakers, the challenge is balancing financial inclusion with consumer protection — and the window to get this right is closing as BNPL becomes more deeply embedded in the consumer economy.
