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

Average US Credit Card APR (2025)

Approximately 20.7% to 24.6%. Rewards cards have higher rates.
