Frequently Asked Questions
How is credit card interest calculated?
Credit card interest is calculated daily. Your APR is divided by 365 to get a daily rate, which is multiplied by your daily balance. This accrues each day and is added to your balance monthly.
Should I pay more than the minimum?
Yes — paying even a small amount over the minimum dramatically reduces payoff time and total interest. Doubling the minimum payment can cut payoff time by 70%.
