How to Challenge Incorrect Credit Card Interest Charges
Understanding Credit Card Interest Charges
Credit card companies calculate interest using methods like Average Daily Balance or Daily Periodic Rate. Common errors include: - Misapplied payments - Incorrect APR implementation - Balance computation mistakes - Retroactive rate increases without proper notice
Example: A $1,000 balance with 18% APR would typically accrue $1.50 daily interest ($1,000 × 0.18 ÷ 365)
Identifying Suspicious Charges
- Review statements using the 50/30/20 Rule (50% needs, 30% wants, 20% savings)
- Compare actual interest against:
- Cardholder agreement terms
- CARD Act protections
- Payment application dates
Pro Tip: Use CFPB's Interest Calculator to verify computations
