What Is a Chargeback? Quick Definition and 2026 Stats

A chargeback is a transaction reversal initiated by the cardholder's issuing bank (e.g., Visa, Mastercard) when a customer disputes a charge on their credit/debit card account (Stanford definition). Unlike a refund--processed directly by the merchant with no fees or network involvement--a chargeback pulls funds via the acquirer, often with $15-100 fees, and holds debit until resolution.

Why It Matters in 2026: Global disputes hit 337M (TechnologyAdvice), with 86% fraud-related (Chargebacks911) and merchants winning just 45% (PayCompass). E-commerce faces rising friendly fraud (62% merchants report increases, SEON), costing billions amid card-not-present sales boom.
