A few key terms to understand:
- APR (Annual Percentage Rate): This is the yearly interest rate that will be applied to your balance, typically shown as a percentage like 29.99%.
- Statement balance: The total amount you owe at the conclusion of the last billing cycle.
- Daily interest rate: The APR calculated on a daily basis.
Example: When you do not pay off your Statement balance:
- You charged a total of $1,200 in a billing cycle of 30 days.
- Your daily interest rate is 29.99% / 365 = 0.0822%
- Your interest charge would be:
$1,200 x 0.0822% x 30 days = $29.58
Tips to avoid high-interest rates.
- Always pay your statement balance in full before the Payment due date whenever possible.
- Pay more than the recommended Minimum Payment Amount.
- Make sure all your credit cards have a “Grace Period.”
- Any late payment will trigger the highest interest rate plus fees.
- Any Promotional rates will no longer be applied if payments are late or not paid in full.
