Have you noticed more people using payment apps at the supermarket checkout line? Splitting milk, bread, and eggs into four installments is no longer unusual. Shoppers think they are outsmarting higher prices at the register. Many families rely on these tools to cope with persistent grocery inflation. Yet, this flexible spending habit might carry a painful, unintended consequence. As Fortune reported, these short loans may actually push shelf prices higher for everyone.
Buy now, pay later platforms have expanded rapidly beyond luxury fashion and electronics. Fortune noted that services like Klarna and Affirm now target daily essentials. A LendingTree survey revealed that 29 percent of consumers now finance groceries. That share has doubled over the past two years alone. About one in three shoppers in grocery lines now uses these installment options.
A groundbreaking study led by Professor Panos Kouvelis highlights the economic damage. The forthcoming paper in Management Science examines how installment fees alter store behavior. Speaking to Fortune, Kouvelis explained that “retailers accepting installment payments raise prices.” He emphasized to Fortune that everyone ends up paying for this business model. The problem stems directly from the transaction fees charged to grocery merchants.
Standard credit card fees usually cost stores two to three percent per swipe. In contrast, installment platforms can charge merchants fees as high as eight percent. Supermarkets operate on razor-thin profit margins of only one or two percent. They cannot absorb these steep fintech charges without losing money. Retailers therefore increase shelf prices across entire categories to protect their bottom line. Fortune detailed that stores may also trim inventories to offset rising processing costs.
This shift penalizes ordinary shoppers who never touch installment apps. Customers paying with cash or debit cards end up subsidizing other buyers. Low-margin retailers simply cannot absorb extra costs without passing them along. A service intended to ease financial stress inadvertently drives overall living costs higher. As Fortune observed, what seems like handy budgeting actually taxes the entire checkout line.
Deferring grocery payments creates a subtle trap for household budgets. Installment loans disguise the real cost of food by spreading bills into smaller chunks. Meanwhile, supermarket sticker prices climb quietly to cover the platform fees. Fortune confirmed that widespread installment usage threatens to keep grocery bills elevated. Next time you shop, remember that spreading out payments carries hidden ripple effects. That convenient four-part plan might make your next cart cost even more.
