Frequently Asked Questions

Get answers to common borrowing, interest calculation, and repayment questions.

Credit card minimum payments are typically calculated as interest plus 1% to 2% of your balance. Because only a tiny fraction goes toward reducing your actual principal, paying only the minimum can stretch repayment over 15 to 25 years and result in paying two to three times your original balance in pure interest!
