What is Buy Now Pay Later (BNPL)? Services Explained for Beginners
BNPL is a short-term financing option letting you buy products now and pay in installments, often interest-free. It's neither a traditional installment loan (which reports to credit bureaus and charges interest) nor purely interest-free--most short-term plans (4 payments over 6 weeks) are 0% APR, but longer terms (e.g., Affirm's 3-48 months) may add 0-36% APR.
Adoption stats: 75 million U.S. users in 2026, up 25% YoY (CFPB data). Unlike loans, BNPL is merchant-specific, powered by apps partnering with retailers like Amazon or Walmart.
Mini Case Study: Sarah, a first-time user, bought $200 sneakers via Klarna. She paid $50 upfront, then $50 bi-weekly--no interest, seamless app tracking. It felt like "free money," but she budgeted to avoid overspending.
