What are buy now, pay later apps?

Buy now, pay later apps (BNPL) allow users to finance their purchases into smaller, equal installments, often interest-free and with minimal fees. These apps may offer four-payment installments or longer-term financing for a variety of purchases (electronics, clothing, jewelry and more) from thousands of well-known retailers. For those who appreciate how to coupon or how to get free stuff, some apps even feature loyalty programs with discounts, in-app deals and rewards when you pay on time.

With rising costs and inflation, tech-smart shoppers are learning how to save money and how to make money fast and using budget apps and BNPL platforms as powerful financial tools. In fact, thanks to their flexible payment plans, BNPL purchases jumped 68% during Black Friday week, according to an Adobe Analytics report.

Popular among people of all ages who want to stretch their paychecks or make big-ticket items more accessible, you can expect BNPL apps to split up your payments over weeks or months.

Understanding the risks of buy now, pay later apps

Companies such as Klarna and Afterpay are just two of the buy now, pay later apps popularized by tempting zero-interest payment plans. And while this type of financing has its benefits, many financial experts have raised caution flags, advising consumers to avoid using these services impulsively. These are loans, after all. If mismanaged, it’s a slippery slope into unsustainable debt, as BNPL services can impact your credit, saddle you with fees and hidden interest and leave you with fewer consumer protections than credit cards.

In general, paying off purchases in full is always the most financially responsible and least risky option. Before purchasing through BNPL services, understand your financial situation. Can you afford to borrow and pay back the loan? Do you have the ability to manage multiple payments and pay on time? Avoid using BNPL apps for unneeded items. If it’s a necessary purchase (a new phone, mattress or computer, for instance) and you’re certain you can make the monthly payments, buy now, pay later apps might be an option for you. Just remember, they’re not all created equal—some are not interest-free, some affect your credit and many will charge a fee if you miss a payment.
