Debit Card Chargebacks vs Credit Card Chargebacks: Key Differences
Debit chargebacks hit harder: funds drain directly from bank accounts with less protection than credit's Reg Z (FTC). No Section 75 equivalent for joint liability.
| Aspect | Debit (Reg E) | Credit (Reg Z) |
|---|---|---|
| Protection | Weaker; no interest buffer | Stronger; issuer absorbs risk |
| Timeline | 60-120 days (issuer/network) | 60-120/540 days |
| Funds Impact | Immediate account debit | Credit line only |
| Fraud Handling | Provisional credit slower | Faster reversals |
| Win Rate for Merchants | 30-45% | Slightly higher (40-50%) |
Note: Conflicting data--Chase 60 days vs. Visa 120 (Chargebacks911). Debit lacks credit's extended protections (Justt.ai).
