How Credit Card Interest Works
Credit card interest uses the daily periodic rate (DPR) method. APR / 365 = DPR, applied to your average daily balance. Interest compounds daily.
Example: 22% APR on $5,000
DPR = 0.0603%. Daily interest: $3.01. With 2% minimum payments:
- Payoff time: 24 years
- Total interest: $8,609
